Glue layer for wig and method of its production
[0001]. This invention relates to a glue for wigs for reliable fixation of the wig on the head, which covers part of the head with thinning hair or without hair, wig, in which the use of such adhesive, and to methods for their manufacture.
[0002]. Usually the wig provides the basis and the hair part, made of natural or artificial hair that is embedded in a base, which is essentially made of faux leather on the merits of soft plastic, such as polyurethane, and is essentially designed in the form of a grid having good ventilation.
[0003]. When inserted into the hair at the base of the wig made of artificial leather usually use the so-called V-shaped is inserted, in which individual hair are inserted into the base of the wig with imitation of their growth from the scalp. When V-shaped insert folded in half hair stick with the outer side of the Foundation of the wig towards the inside using a special tool, such as wig making the hook, create the "root" part of about 1 mm and attach the hair to the base of the wig with obtaining V-shaped, pulling one end of the folded double hair again to the outer side of the base. However, because the insertion of hair without additional operations leads to the fact that hair is easily pulled the basis of your finger or combing, we need to fix the hair attached to the base of the wig. For such a commit after inserting the hair on the entire inner side of the framework wig made of artificial leather is usually applied diluted with an organic solvent adhesive that sticks to the artificial skin and fixed it, thanks to the "root" part of the hair is located between the artificial skin and the adhesive coating, with the possibility of fixation (see, for example, patents 1 and 2).
[0004]. To be worn on the head of this wig with adhesive fixing your hair on the inside of the basics of artificial leather, use your own natural hair around the field of rare hair or areas of hair loss, attaching special clamp to the inside of the basics of artificial leather and stitched them with your own natural hair, weaving them into hair wig or tying them to the cord placed around the perimeter of the base.
In another case, the wig is worn directly sticking the basis of the artificial skin to the scalp with glue or sticky substance. In other words, when gluing the wig to the scalp fast-acting glue or adhesive the adhesive substance or a substance prepared each time you use the wig, and the adhesive is applied or adhesive tape stick on specified areas on the perimeter of the inner is the first part of the foundations of artificial leather, resulting glue or tape to be stuck to the scalp. When removing the wig, with masking tape, which is adhered by a simple pressing, it can be relatively easy to separate from the scalp and fast-acting glue requires slow and careful departments with raskreposchayuschego substance applied between the wig and scalp.
Thus, the required bonding and releasing the adhesive or sticky substance (adhesive tape), carried out every time when donning or removing the wig, are rather burdensome task.
[0005]. In this regard, patent 3 (published patent application Japan 2001-89921 A) describes the wig with the adhesive layer is previously executed on the entire inner side of the Foundation of the wig designed for adhesion to the scalp.
Specified wig includes a base and two adhesive layer on its inner side. The first adhesive layer for fixing the hair on the base by applying glue to the inner side of the Foundation of the wig captures the hair attached to the base, and the second adhesive layer applied on the entire inner side of the framework on the outer side of the first adhesive layer, glues a wig to the scalp.
In particular, as disclosed in patent 3 (description, column [0010]), the first adhesive layer is used for clamping and fixing the root of hair is inserted into the wig again and protruding from its inner side (hereinafter in this document, the root of the hair, protruding from the inner side, referred to as a part of the hair under the needle heel), between the base of the wig and glue, and as described in the patents 1 and 2, the hair is fixed by blowing fast drying adhesive with its subsequent condensation on the inside of the Foundation of the wig.
The second adhesive layer are made so that for bonding basics wig directly to the scalp sticky substance placed by blowing across the inner side of the Foundation of the wig on top of the first adhesive layer after curing and paste this adhesive strip, which is removed while wearing the wig, and the entire surface of the second adhesive layer paste to the scalp.
In other words, in the adhesive layer of two-layer structure of the first quick-drying adhesive layer is applied, followed by curing on the inside of the basics wig for fixing hair wig and then hardened first adhesive layer is applied to the second adhesive layer of the adhesive substance other than the specified quick-drying glue for gluing the basis of the wig to the scalp.
[0006]. As disclosed in the patent 3, etc. in the traditional wigs, with system adhesion to the scalp for fixing the "root" part of the hair facing the inside of the basics of artificial leather, quick-drying glue is applied, followed by curing on the inner side of the base, then n is glue put sticky substance, which is not cured for a long time, or paste sticky tape to glue the wig to the scalp, and thus, consistently causing the first and second adhesive layers, different in type, it is possible to fix hair wig in the base of the wig and its adhesion to the scalp.
Thus, as in traditional systems, the first adhesive layer is made of quick-drying glue, when the user tries to attach it to the scalp, this layer is already provided utverzhdennym and has no adhesive property. This is due to the lack of stickiness of the adhesive of the first adhesive layer to the scalp as a result of curing, although this adhesive exhibits adhesiveness when a chemical reaction with the base of the wig is made of plastic. On the other hand, the second adhesive layer, without the first, you may glue the wig to the scalp due to the stickiness, but cannot fix the hair at the base of the wig. Because only physical stickiness sticky substances shown when clicked, instead of gluing ability, manifested by a chemical reaction, such gluing ability does not commit the hair and will not prevent them from pulling. Traditional sticky substances do not have the adhesive power required for fixing the hair in the base of the wig, and it is not known Lipki the substances for application in a single layer on the bonding surfaces with very different physical properties, such as the base of the wig is made of solid polymer, and human skin. Therefore, for forming a double adhesive layers must consistently apply various substances, glue and sticky substance with a different application. Thus, it is not yet known adhesive or unknown sticky substance, doing or performing both functions: fixing hair wig it and gluing the base to the scalp.
[0007]. In this regard, although the wig can be firmly glued to the scalp not using sticky substances and adhesive, the bonding breaks down quickly in the environment, if your scalp is oily or sweaty, or you receive the stretching force when brushing. Although the deterioration of the adhesive capacity, you can apply a new adhesive for re-use, it leads to hardening of the wig, the increase of its thickness as a result of repeated application of the adhesive and the deterioration of the appearance of the wig wearing.
[0008]. In addition, the wig made of artificial leather light passing through the gaps inserted hair, can be reflected from the base of the wig, causing unnatural lustre.
The brilliance of the reflected light can easily be spotted by nearby people, so it must be eliminated. To eliminate Shine known the following methods: physical Zarubina surface is the exploits of sandblasting and the like, squeezing a small concavity and convexity on the surface, the addition of foreign substances, for example, inorganic. Sandy stream and squeezing terrain suitable for processing plate and filmy products using machines, but not suitable for processing basics wig having a curved nose portion. Although the method of adding foreign substances, for example, inorganic, simple and suitable for the manufacture of the wig, to achieve a natural Shine hard and this process leads to the lowering of the basics of the wig.
In addition, the elimination of Shine framework wig having a curved nose portion, as disclosed in the patents 4 and 5, which describe how to zagrobelny of the surface by exposure to random surface of the base of the wig corrosion to get a small convexity and concavity.
Patent 1: published patent application Japan S52-123755 And (1977).
Patent 2: Japan patent 3484565.
Patent 3: published patent application Japan 2001-89921 A.
Patent 4: published patent application Japan H02-216207 And (1990).
Patent 5: published patent application Japan H03-69601 (1991).
[0009]. As mentioned above, traditional glued to the scalp of the wig is made so that to capture the "Korneva the part of the hair, inserted into the base of the wig on the inside of the basics out of quick-drying glue, as described in patents 1 and 2, which adheres and hardens, then on the inside of the basics of wig out of a sticky substance that is described in the patent 3, to form a second adhesive layer for adhesion to the scalp. However, it is not known adhesive or sticky substance that implements or implements independently both features: durable bonding hair wig and glued to the scalp. In addition, the wig, described in the patent 3, not detachable from the scalp, and therefore is not suitable for reuse. Thus, the traditional wig has no adhesive layer, which simultaneously performs one function strong gluing hair wig to the base of the wig and gluing the wig to the scalp.
[0010]. In addition, suppression of surface gloss basics wig by physical zagrublenija this surface and adding foreign substances, for example, inorganic, is associated with some difficulties. Adding foreign substances, for example, inorganic, moreover, leads to hardening of the basics of the wig, so she, being attached to the scalp, can not repeat the movements of the skin, which leads to deterioration of the strength of adhesion of the base to the scalp, and the base can be easily separated from her is Jena.
[0011]. Taking into account above-mentioned problems, a first object of the present invention is to provide an adhesive for a wig, containing one layer made with the possibility netslaves bonding to the inner side of the Foundation of the wig by chemical reaction and with the possibility of adhesion to the scalp pressing with subsequent peeling.
The second objective of the present invention is to provide a wig, having one adhesive layer made with the possibility of reliable fixation of the hair at the base of the wig and gluing the wig to the scalp.
A third objective of the present invention is to provide a method simple production of the above adhesive for a wig.
[0012]. The adhesive for a wig, proposed to solve the first problem, is different in that it has one layer made with the possibility netslaves bonding to the inner side of the Foundation of the wig and with the possibility of adhesion to the scalp pressing with subsequent peeling.
Glue for the proposed wig also differs in that it has an adhesive layer made with the possibility netslaves bonding to the inner side of the Foundation of the wig, and one side of this layer is bonded by chemical reaction to the inside of the basics of the wig in the formation of gel in the adhesive R is the target, printed on the inside of the basics of the wig, and implements the function of fixing the "root" part of the hair, indicated on the inside of the Foundation of the wig, and the other side of the adhesive layer is glued to the scalp pressing without the use of chemical reactions and are made with the implementation of the functions possible subsequent flaking from the scalp. Here the function of a possible subsequent flaking from the scalp implemented after the completion of the gelation reaction in the adhesive layer.
In the above structure, the adhesive layer contains a urethane gel, preferably polyurethane contact adhesive from a mixture of two fluid made of a basic reagent and a hardener, with the basic reagent is a high molecular weight alcohol for polyurethane as the main component and the curing agent as the main component contains a polyisocyanate.
Due to this structure can be created adhesive for a wig that contains one adhesive layer, which implements, as a function of fixing the "root" of the parts of the hair that is inserted in the base of the wig, and function of a possible subsequent flaking from the scalp.
[0013]. For solving the second problem proposed wig, which is characterized in that it includes a base inserted in her hair and the adhesive layer deposited on the inner side of the Foundation of the wig, and specified the first adhesive layer has one side bonded by chemical reaction to the inside of the basics wig during the gel formation in the adhesive solution applied on the inside of the basics of the wig, and the other side of the adhesive layer is glued to the scalp pressing without the use of chemical reactions with the possibility of flaking from the scalp.
In the above structure, one side of the adhesive layer is preferably bonded through a chemical reaction to the inside of the basics wig during the gel formation in the adhesive solution applied on the inside of the basics of the wig, and performs a function of fixing the hair the specified adhesive, expressed in fixing the "root" part of the inserted hair, placed on the inside of the Foundation of the wig, and the other side of the adhesive layer adhered to the skin of the head pressing, and, since the bonding carried out without the use of chemical reactions, another function of the adhesive layer is manifested in the ability of subsequent peeling off the scalp for reuse.
Because the wig with such a structure contains only the base and one adhesive layer that implements the function of fixing the "root" part of the hair and the function of the subsequent peeling off the scalp for reuse, the design is quite simple. Therefore, the wig can be thin and light. And because the side of the adhesive layer, designed for adhesion to the skin of the head, is made with the possibility of exfoliation for re-use, the wig can be used repeatedly and, therefore, to have a low cost.
[0014]. In this structure, the surface of the base wig is preferably treated to eliminate Shine. This treatment is carried out by introducing into the base of the wig eliminates Shine supplements with the subsequent formation on the substrate surface small areas of concavity and convexity.
Eliminates Shine the additive is preferably inorganic particles, and lots of small concavity and convexity performed by transferring a pattern of small cells. After processing basics wig to eliminate Shine making it eliminates Shine additives and formation of small areas of concavity and convexity light from the fundamentals is reflected absently and wear a wig difficult to detect.
[0015]. In accordance with a preferred implementation of the present invention, the base of the wig is made of synthetic PU leather, and the adhesive layer of the wig is made of urethane gel. Specified urethane gel contains polyurethane contact adhesive from a mixture of two fluid made of a basic reagent and a hardener, which OS is the ESD agent is a high molecular weight alcohol for polyurethane as a main component, as the curing agent as the main component contains a polyisocyanate. Formed in polyurethane wig one adhesive layer of urethane gel reacts very well to the movement of the scalp, moving with her while wearing the wig, and sufficient fixing the wig achieved without compromising the strength of adhesion to the scalp.
[0016]. To accomplish the third objective, a method for manufacturing the adhesive layer, is made on the inner side of the framework proposed wig, which differs in that form, followed by mixing the solution containing the primary agent, curing agent and an organic solvent, and leave it at ordinary temperature for a predetermined time for reaction, then apply this solution on the inside of the basics of the wig is heated to a predetermined temperature higher than normal, glued to the inner side of the Foundation of the wig and cooled to normal temperature after heating for a predetermined time to form the adhesive layer, thus giving the other side of the adhesive layer that appeals to the base of the wig, the function of fixing hair for fixing the "root" of the parts of the hair, inserted with penetration on the inside of the Foundation of the wig, and the other side of the adhesive layer, which is designed for p is kleivane to the scalp, function any further flaking from the scalp.
In the above structure, the adhesive layer is made of urethane gel and preferably contains the polyurethane from a mixture of two fluid made of a basic reagent and hardener, in which the basic reagent is a high molecular weight alcohol for polyurethane as the main component and the curing agent as the main component contains a polyisocyanate.
In accordance with the above-described production method is easy to make the adhesive layer for wig, containing a single layer that performs the function of fixing the "root" part of the hair, inserted into the base of the wig, and function of a possible subsequent flaking from the scalp.
[0017]. The production method proposed wig includes the process of forming the basis of the wig is made of soft plastic, the process of inserting hair in the specified basis and the process of forming on the inside of the basics of the adhesive layer and differs in that form, followed by mixing the solution containing the primary agent, curing agent and an organic solvent, and leave it at ordinary temperature for a predetermined time for reaction, then apply this solution on the inside of the basics of the wig is heated to a predetermined temperature above about who offered, glued to the inside of the basics of the wig and cooled to normal temperature after heating for a predetermined time to form the adhesive layer, thus giving the wrong side of the adhesive, which is converted to the base of the wig, the function of fixing hair for fixing the "root" of the parts of the hair, placed on the inside of the Foundation of the wig, and the other side of the adhesive layer, which is designed for adhesion to the scalp, is a function of the possible subsequent flaking from the scalp.
In the above structure, the hair is preferably inserted with obtaining V - or U-shaped with the penetration from the surface to the inside of the basics of the wig for the formation of the "root" of the parts of the hair and back of their drawing to the surface, and the solution for forming the adhesive layer is applied on the inside of the basics of the wig is heated to a predetermined temperature above normal and glued to the inner side of the base, whereby the "root" of the hair are fixed on the inner side of the Foundation of the wig.
In accordance with the above-described production method can produce the wig that implements one adhesive layer is a function of fixing hair for fixing the "root" of the hair parts and function of a possible subsequent peeling off to the head. Since the proposed adhesive layer these functions are implemented, the wig can be made thin and light, in contrast to the known two adhesive layers formed separately. And because that side of the adhesive layer, which is designed for adhesion to the skin of the head, is made with the possibility of exfoliation for re-use, the wig can be used repeatedly and, therefore, to have a low cost of production.
[0018]. Create a wig preferably includes processing framework to eliminate Shine, contains the process of depositing the basis of the wig eliminates Shine additives and formation of small areas of concavity and convexity on the surface of the wig. The process of depositing the basis of the wig eliminates Shine supplements are produced during the manufacture of the framework by applying and drying the solution with inorganic particles added to the solution, to the base of the wig. For the formation on the basis of the wig sites small concavity and convexity it is covered with a fine-meshed net after making the basis of the wig eliminates Shine additives and form a concave and convex areas through migration pattern of small cells. Due to such processing, the basics of the wig can be made wig, which is almost invisible when n is due to scattering of the reflected light. Since such processing fundamentals of wig do you make it eliminates Shine additives and the creation of small areas of concavity and convexity, it is possible to achieve the natural splendor of the framework.
[0019]. In a preferred embodiment of the invention a soft plastic that forms the basis of the wig is a polyurethane, and the adhesive layer is made of urethane gel. Specified adhesive layer formed from a polyurethane from a mixture of two fluid, namely the main reagent and hardener, and the main agent is a high molecular weight alcohol to polyurethane as the main component and the curing agent as the main component contains a polyisocyanate. The creation of the adhesive layer of urethane gel gives such a layer the ability to pull away later for re-use. Also, because the base of the wig, and the adhesive layer is made of urethane, base wig is flexible and well follows the movements of the scalp.
In accordance with the adhesive for a wig and a production method of the adhesive layer for wig using the proposed adhesive, in a single layer can be implemented as a function of fixing the "root" part of the hair, and function of a possible subsequent peeling off the scalp for reuse.
In the accordance with the proposed wig and method of its production can be offered wig having a two-layer structure, with the base of the wig and one adhesive layer made of the adhesive for a wig. As one adhesive layer implements the function of fixing the "root" part of the hair and the function of possible future flaking from the scalp to re-use, it has a simple structure. Therefore, the wig can be made thin and light.
In addition, one side of the adhesive layer, which is clearly for adhesion to the skin of the head, is made with the possibility of subsequent recovery by simple washing with water part of the adhesive layer for reuse. Therefore, you can create a cheap wig.
In addition, due to the processing surface of the base wig to eliminate Shine can be offered wig, which when worn it is difficult to detect.

[0023]. Hereinafter described in detail embodiments of the present invention with reference to the accompanying drawings. In this regard, it should be noted that what is depicted in the accompanying drawings options in no way limit the scope of the present invention, and are intended to objasneni and understanding.
First, a description of the wig using the adhesive layer for the proposed wig.
Figure 1 shows the cross-section, schematically illustrating the structure of a wig in accordance with the first embodiment of the present invention. As shown in figure 1, the wig 1 includes a base 2 wig, hair 3, inserted into the base 2, and one adhesive layer 4 for wig (hereinafter referred to as an adhesive layer). Hair 3 made of human or synthetic hair. As shown in the drawing, the hair 3 can be inserted with obtaining V - or U-shaped through the surface side of the framework 2 with the release on the inner side and stretched out again on the surface side of the framework 2. The section of hair, put on the inner side of the framework 2, is called the "root" part 3A of the hair. This chip is called here is essentially V-shaped. The base 2 may be made of ultra-slim faux leather with soft plastic, such as polyurethane.
[0024]. In the proposed wig layer 4 has an original structure with the specific property, namely, that one side is glued without the possibility of exfoliation to the inner side of the framework 2, and the other side may be adhered by pressing to the scalp with the possibility of exfoliation. The above-mentioned side layer 4 bonded to bezothodnosti exfoliation to the inner side of the framework 2 and performs a function of fixing hair for fixing portion 3A, inside the framework of the wig between the said inner side fundamentals wig and one side of the adhesive layer. Moreover, since the other side of the layer 4 may be bonded by pressure to the scalp with the possibility of exfoliation, the wig can be reused. Thus, the proposed wig 1 has a two-layer structure formed by the base 2 and used it one layer 4, which is glued without the possibility of exfoliation to the inner side of the framework 2, thus realizing the function of fixing parts 3A and possible subsequent peeling off the scalp for reuse.
[0025]. Layer 4 in accordance with the present invention can be performed by transmitting or transparent adhesive for a wig, having the following component and property, and this layer is firmly bonded to the base 2 and part 3A and executed with the possibility of flaking from the scalp. In this regard, after the formation of layer 4 on the base 2 is preferably applied to the adhesive layer with a release sheet 5 made of a vinyl chloride film or similar material and is easily peelable by hand.
[0026]. In this application, in addition to the term "adhesive ability, accompanied by a chemical reaction uses the terms "adhesive" or "adhesive layer", kotoryeprodayut gluing simple pressing without the use of chemical reactions, with this in mind, in the present invention, the term "adhesive layer 4 for wig" or "glue" should be interpreted expansion with the inclusion of both concepts.
The layer 4 is made so that one side is designed for bonding to the base 2, is attached to the inside surface of the base 2 during the gelling reaction in the adhesive solution applied on the inside of the Foundation of the wig. Part 3A is placed between the base and layer 4 after its adhesion to the base 2, and at the same time it is recorded in layer 4.
On the other hand, the second side of the layer 4 may be bonded by pressure to the scalp with the possibility of subsequent peeling from it. This function is a possible subsequent flaking from the scalp layer 4 is implemented after the completion of the gelation reaction of the adhesive. Therefore, the layer 4 after completion of the reaction, gelation can be glued to the scalp through intermittent application of small efforts at ordinary temperature, i.e. it has the property of a layer of contact adhesive (so-called adhesive layer), allowing the bonding pressing. In addition, layer 4 after the gel-forming reaction has the possibility of multiple bonding to the scalp by wiping its surface with a small amount of water or the organic solvent. In the present invention this is called a function of a possible subsequent peeling or merely a function of exfoliation, allowing re-gluing.
[0027]. Next, given a description of the proposed layer 4.
As an adhesive for a wig that is used for forming layer 4, use such classes of substances, such as polyurethane, polymethylmethacrylate and rubber. The adhesive for a wig made of polyurethane has good adhesion, as described below, for fixing portion 3A in base 2, and has the property of strong netslaves bonding layer 4 to the base 2. Besides, he may very well pull away from the head for bonding to the head and does not cause strong irritation of the skin.
Therefore, it can be preferably used as an adhesive for a wig for the formation of the proposed layer 4.
[0028]. On the other hand, the adhesive polymethyl methacrylate has a very good stickiness, but not exfoliate for subsequent use, and in some cases causes severe skin irritation. Rubber exhibits excellent initial tack, but his ability to pull away for subsequent use is significantly reduced over time. Moreover, in the preferred embodiment of the invention the specified adhesive for a wig is not a form of glue on the basis of polymethylmethacrylate is or kauchukopodobnoe polymer, since he can't repeat the movements of the skin, being glued to the scalp, due to the stiffness of the polymer tends to flake off due to the deterioration of the strength of adhesion to the scalp, its adhesiveness is insufficient to capture the "root" of the parts of the hair at the base of the wig, the adhesion between the adhesive layer and the base of the wig is too weak and is easy peeling.
[0029]. Next is a detailed explanation of the case create a layer 4 using the adhesive of polyurethane.
As such an adhesive, preferably a mixture of two fluid containing the main agent and the curing agent.
The basic reagent may be a high molecular weight alcohol for polyurethane as the main component and the main component of the hardener may be a polyisocyanate. In a preferred embodiment of the invention, the two fluids mix for the implementation of the gelation reaction, which is obtained after the specified reaction, which can be accelerated by heating.
Isocyanate contained in the curing agent in the gelation, allows not only the physical bonding with the surface tension, and chemical bonding. Thus, significantly improved the adhesion between the base 2 and the layer 4 and the fixation of the base part 2 of the hair under the beard kr is CCA, inserted in this basis, with the resulting fixation is not inferior to commit a conventional hair glue. In the present invention, the fixation is defined as the bonding of the bases 2 and the "root" part of hair inserted into the basis with the proposed layer 4, and differs from the conventional bonding heat-sensitive adhesives. As the adhesive for a wig made of polyurethane made from a mixture of two fluid forms a layer 4 of the gel structure formed after a chemical reaction, i.e. the adhesive, it perfectly follows the movement of the scalp while wearing the wig 1, and the strength of adhesion to the scalp is not getting worse, thus achieving sufficient stickiness wig.
[0030]. Next, the description is given of the method of fixation parts 3A hair, inserted into the base 2. This can be done by mixing adhesives containing monomers from a mixture of two fluid polyurethane type, applying the obtained adhesive on the base 2 with a small amount of organic solvent base material that removes Shine, added to these two fluid environments, and drying.
If the substrate 2 is a urethane elastomer, as such a solvent can be used dimethylformamide and methyl ethyl ketone. To adjust the size of the fixing layer 4 with the parts 3A and stickiness to the head can selection ratio of the main agent and hardener glue, made from a mixture of two fluid polyurethane type, selection applied viscosity and setting time after mixing of the two fluid and before applying on the basis of 1 inserted in her hair 3.
[0031]. In accordance with the present invention, the layer 4 may be applied partially on the site of the inserted hair 3, instead of the whole base 2. If the region in which the inserted hair 3 are not performed on the peripheral area of the framework 2, the adhesion to the scalp easily feasible using layer 4, border bases 2 and scalp difficult to detect, thus while wearing the wig improved natural appearance.
Thus, the present invention is to use one of the adhesive layer 4, which can replace the first adhesive that performs the function of fixing the "root" part of the hair, and the second adhesive that performs the function of bonding to the scalp, performed separately in a known prototypes. Due to this, the present invention proposed a simple structure, which can be implemented through framework 2 and layer 4. The thickness of the layer 4 may be just sufficient for fixing portion 3A, for example, about 0.05 mm, which is equal to the diameter of the inserted hair, and, consequently, the wig 1 can be made easy.
In addition, layer 4 on the side which is intended for bonding to the e of the head, made with the possibility of exfoliation and stickiness can be restored by simple washing with water parcel layer 4 for reuse. Therefore, the wig 1 may have a small cost and sold at a low price.
[0032]. Next, a description of the wig with the base that removes the Shine, which is an improved version of the first variant implementation of the present invention.
Wig 1 in accordance with the first option is preferable, for example, to increase the amount of hair in the frontal part by gluing the front offset from the line of the original position of your own hair, but glued so the base of the wig is easily noticeable. Especially due to the fact that the proposed pillar 2 has a smooth and shiny surface, since it is made of faux leather. Therefore, as reflected from the surface of the artificial leather light visible through the inserted hair 3, it is very important glued artificial skin to perform invisible.
[0033]. In accordance with the second embodiment of the present invention proposed the Foundation of the wig is made of synthetic leather, the brightness of which is reduced to a level of brightness of the scalp, as well as the form and structure of the surface, imitating the pattern of the scalp, made up of small concavity and vypuklost the th. Figure 2 is a cross section schematically depicting the structure of the wig 10 with a base 12 that removes Shine, in accordance with the second embodiment of the present invention, and figure 3 depicts a top view of the framework 12, as shown in figure 2. As can be seen from figure 2 and 3, the difference of the wig 10 from wig 1, provided in the first embodiment, is that to eliminate the Shine on the surface of the substrate 12 is a plot 12D small concavity and convexity and the basis of the wig made it eliminates Shine additive 6. This plot 12D includes a concave area 12V and a convex section 12C and has a pattern that mimics the pattern of the scalp.
Therefore, even if the artificial skin is visible through the inserted hair, you can make it look like the skin of the head carrier wig, and due to diffused reflection of light by small concavity and convexity can be reduced unnatural Shine. Moreover, the proposed additive 6 made in artificial skin to a certain depth from the surface. Thus, there is an additional suppression of unnatural Shine to Shine scalp. Supplement 6, as shown in the drawing, bury in a certain area 12A from the surface of the artificial leather, the Shine of which, as well as hardness and transparency can be adjusted by the amount of additives 6. In the rest of the om wig 10 is similar to the wig 1.
[0034]. In case of execution of the fundamentals of thin wig to make it easy to eliminate Shine and capable glued able to repeat the movement of the scalp, it is preferable to make the additive 6 shallow from the surface of the substrate 12. For example, if the thickness of the bases 12 of the order of 0.05-0.1 mm, the additive is preferably 6 contribute to a depth of about 0.01-0.015 mm from the substrate surface of the wig.
If you make an additive to a depth of less than 0.01 mm, the Shine is eliminated insufficient, and if the depth of 0.015 mm, Supplement 6 leads to the lowering of the framework 1, which may not sufficiently be repeated movement of the scalp, and therefore in this area are not preferred. In addition, it is undesirable to make too many additives 6, because it leads to a whitish haze and poor transparency.
As an additive 6 can be used various inorganic particles. As a material for the above inorganic particles 6 can be used silica, titanium oxide, aluminum oxide, hydrate alumina, magnesium carbonate, calcium carbonate, zeolite or glass. It is especially recommended to use a silica powder with a particle diameter of about 1-10 micrometers. The quantity of powder of silica is preferably 5-25% by weight thermoplastische elastomer, RA is solved in an organic solvent. Due to the introduction of powdered silica as an additive 6 only on the surface side of the Foundation of the wig, because the color of the skin of the head carrier wig is visible through it, the border basics 2 that removes the Shine and scalp almost unnoticeable, thereby improving the natural appearance while wearing the wig.
[0035]. Based on the 12-transfer of a pattern of small cells setcompany fabrics, etc. as described below, executed plot 12D, which has a pattern that mimics the pattern of wrinkles scalp.
[0036]. The proposed base 12 in the wig 10 is able to eliminate the gloss additive 6 and scattering section 12D of the reflected light. Because powdered silica is transparent and the color of the skin of the user's head is visible through the base, the boundary between the base of the wig and scalp is almost unnoticeable, which makes the appearance while wearing the wig more natural.
In addition, the base of the wig that removes the Shine becomes savage because made of inorganic substances, and its color and transparency are very dependent on them, and therefore difficult to perform a basis similar in color to the scalp of the user, but the proposed framework allows to deal with it.
In accordance with the present invention can be made wig 10, which performs the function of fixing the "root" part of the hair, inserted in the warp wig, and function of a possible subsequent peeling off the skin of the user's head and which has a sheen and pattern of wrinkles, similar to the scalp, through the use of bases 12, in which very effectively addressed Shine.
[0037]. The following is a description of the proposed method of manufacturing layer 4 for wig and wigs 1 and 10, are equipped with such a layer.
First described method of manufacturing basics 2.
At the first stage of processing of a thin sheet or film of artificial skin, like the skin of a human head, get the base 2, in which you want to insert the hair by applying the solution (hereinafter referred to as thermoplasty elastomer solution), in which the organic solvent is dissolved granulated thermoplastic elastomer soft plastic with accommodation on a positive form for molding (for example, gypsum and the like), imitating the shape of the head carrier wig and prepared by casting and drying.
For this purpose suitable thermoplastic elastomers, but the preferred one is, for example, urethane elastomer, and optionally can be added fungicide, etc. the size of the wig can be determined depending on the degree of baldness of the head carrier, and may be made of the so-called partial wig or wig, covering the whole head. Artificial the skin may be made in the form of a sheet, if used on a flat plot of the user's head.
[0038]. The following is a description of the method of manufacturing base 12, which is the base 2, which eliminated the glitter in accordance with the second embodiment of the invention.
The first stage is similar to the above. Performed at the first stage base 2 to eliminate Shine processed in the subsequent steps, thereby giving the surface of the substrate wig natural looking.
More specifically, in the second stage solution in which an additive 6 in thermoplastic elastomer solution made of inorganic particles used for the production bases of the wig, put on the surface of the base, made in the first step, and dried. Here, the design basis wig thickness of the order of 0.05-0.1 mm, depth-of-field 12A containing the additive 6, after application and drying of the solution is preferably about 0.01-0,015 mm this purpose may be selected viscosity thermoplastische elastomer in the applied solution. You can use various inorganic particles, but preferred is a silica powder with diameter of the order of 1-10 microns, the amount of which is preferably 5-25% by weight thermoplastische elastomer dissolved in nanoceria solution. If you need polymodality 6 can be made of the ultraviolet absorber or the oxidant to prevent yellowing.
[0039]. In the third stage base 12, on which surface at the second stage included Supplement 6, cover with a fine-meshed net, cause the solvent of the base material of the wig, after drying mesh removed and thus form the plot 12D made in the form of small cells on the substrate surface of the wig.
Wire mesh used at this stage, can be made of any material that is not soluble in applied to the base of the wig in the solvent. For example, if the base of the wig is made of polyurethane, it is possible to use nylon fine mesh. This network is preferably woven from filaments with a diameter of 0.03-0.1 mm, and has a size of about 30-100 cells (threads/inch) in order to reduce light reflection and to obtain a structure similar to that of the scalp.
[0040]. On the second and third stages of the basis of 2, made in the first step, is treated to eliminate Shine, thereby giving the basis of 12 natural Shine. Thus, the base 12 is fixed glitter combination of the formation region 12A modified inorganic particles and forming section 12D.
[0041]. The following steps are common in the manufacture of wigs 1 and 10.
In the fourth stage of processing in the wig 2 or 12 is inserted with obtaining V-shaped and the like, of human or artificial hair.
[0042]On the fifth stage of forming the layer 4 on the inner side of the wig 2 or 12 is inserted in her hair. The layer 4 may be accomplished by applying adhesive that performs the function of fixing portions 3A on the inner side of the framework 2 or 12 that removes the Shine, and the function of adhesion to the head, and drying.
For applying glue on a wig, you can use spray or brush.
[0043]. Next, on a separate example explained the stage of forming the layer 4.
Layer 4 is performed on the back side (inner side) basics 2 or 12 is inserted in her hair. The basis of 2 or 12 turn inside out and fix on a positive form for molding imitating the shape of the head carrier wig, and in such position on the inner side of the Foundation of the wig form the layer 4. The specified tool in the shape of the head is made from, for example, thermosetting epoxy resin.
First mix the adhesive monomer for wig and an organic solvent. As the adhesive monomer for wig can be used, the adhesive consisting of a mixture of two fluid environments. In addition, if necessary, may be used an organic solvent basics 2 or 12. This solution advocated at ordinary temperature for a preset period of time for reaction to create adhesive for a wig. Here advocating for a predetermined time is carried out to establish the relationships m is waiting for molecules in solution.
Next, the adhesive for a wig, settled for a pre-determined time, applied on the inner side of the framework 2 or 12 with getting the desired thickness, and dried for a predetermined time at an elevated temperature and cooled to normal temperature after drying, thus forming layer 4. To obtain a layer 4 of a desired thickness can again apply the adhesive solution and dried by heating.
In this regard, the adhesion between the base 2 and the layer 4, between the base 2 and 3A inserted in her hair occurs when the gelation by drying within a predefined time at elevated temperatures. Although the adhesive layer, formed only by the gelation of the adhesive solution, performs the function of bonding to the scalp, the adhesion between the base 2 and the layer 4, between the base 2 and 3A inserted in her hair is not shown.
[0044]. At the fifth stage of processing the proposed layer 4 is formed, and wigs 1 and 10 can be manufactured. In addition, the layer 4 may be applied to the sheet 5 for peeling the purpose of the protection layer prior to use.
[0045]. As an example, in accordance with the present invention was made wig 10 having a base 12.
At the first stage of processing on pre-prepared plaster mould in view of the head carrier wig has applied the solution, in which the urethane elastomer was dissolved in dimethylformamide and methyl ethyl ketone, and to which was added fungicide, and dried for one hour at elevated temperature of 60°C to form the basis of 1 thickness of about 0,04 mm
[0046]. The second phase was prepared solution to eliminate Shine, which in dimethylformamide and methyl ethyl ketone dissolved urethane elastomer and added fungicide, and, in addition, were added silica powder (average grain diameter of 3.1-4.1 micrometer) as it eliminates Shine additives 6, an ultraviolet absorber and an antioxidant. The weight of the silica amounted to about 15% by weight of the urethane elastomer. The solution is to eliminate Shine was applied on the basis of 1 wig and dried for 2-4 hours at 60°C.
[0047]. Next, in the third stage, the surface of the base of the wig, in which the second stage was made Supplement 6, coated wire mesh, which was used mesh commercially available nylon pantyhose, caused dimethylformamide and methyl ethyl ketone as an organic solvent basis wig and was dried for 4 hours at a temperature of 100°C. After drying, this mesh was removed, resulting in a surface of the base wig was formed section 12D. The diameter of the thread used grid was 0.05 mm, and the number of cells is approximately 50 mesh (threads/inch).
Thus, on the substrate surface wig, made of polyurethane, formed region 12A containing the additive 6 and section 12D, and thus made the basis of 12. The thickness of the whole base 12, is increased by 0.01-0.015 mm in thickness region 12A containing the additive 6, 0.5-0.6 mm
Due to the fact that the basis of 12 was made of ultrafine through it was visible color scalp media and was saved transparency and, in addition, reflected light from the Foundation was comparable with the reflection from the scalp, thus was achieved the natural appearance with reduced gloss.
[0048]. In the fourth stage of the artificial hair made of nylon, have been inserted with obtaining a V-shape in the base 12.
[0049]. In the fifth stage was formed layer 4 on the inner side of the Foundation of the wig 12 inserted in her hair. More specifically, the base 12 is inserted in her hair was turned inside out and placed on a positive form to mold having the shape of the head carrier wig.
[0050]. As a glue to create a layer 4 was used a mixture made of consisting of two fluid polyurethane binder monomer containing a main agent and the curing agent and dimethylformamide as the organic solvent 12. Here is basically the reagent as the main component contained high the molecular alcohol for polyurethane as a main component, as the curing agent as the main component contains a polyisocyanate.
The main agent and hardener polyurethane adhesive from a mixture of two fluid and dimethylformamide as the organic solvent were mixed. This solution was distilled in 1-2 hours at room temperature for reaction. The viscosity of the solution after settling preferably comprised between 2000-3000 sandypaws. Specified adhesive solution was applied by brush on the inner side of the framework 12, dried at a temperature of 80°C for 10-15 hours and after drying cooled to room temperature. Thus was formed a layer 4 of a thickness of 0.05-0.2 mm
[0051]. Figure 4 is an image obtained with the scanning electron microscope (SEM), sections 12D small concavity and convexity performed on the surface of the wig 10, made according to the example above. The accelerating voltage of the electron was 15 Kev and a magnification of 150. As can be seen from the drawing, the surface is not flat and smooth, and rough due to the introduction of additives 6. Lots of small concavity formed by the two line sections in the horizontal direction of the drawing, the components of the drawing grid.
[0052]. Figure 5 (A) represents the image obtained with the scanning electron microscope, and (C) schematics which depicts the corresponding surface and the cross section of the wig 10, manufactured according to the example above. The accelerating voltage of the electron was 15 Kev and a magnification of 100. As shown in figure 5, the wig 10 using base 12, had a two-layer structure containing a base 12 with a thickness of about 0.06 mm, and the layer 4 with a thickness of about 0.19 mm, and the base 12 have been inserted artificial hair 3 with a diameter of about 0,06 mm Of the drawing it is seen that the substrate surface region 12 that removes Shine, made in the form of plots 12D.
[0053]. 6 (A) represents the image obtained with the scanning electron microscope, and (C) schematically depicts the corresponding surface and the cross section of the wig 10, made according to example 2. The accelerating voltage of the electron was 15 Kev and a magnification of 200. As can be seen from Fig.6, the "root" part 3A hair was inserted from the upper part 12 in its lower part and the fixed layer 4 in the base 12. Shown here, the layer 4 has a thickness of 0.19 mm, but when the bonding layer 4 to the scalp was appropriate thickness 0,04-0,06 mm
[0054]. They studied the strength of the fixation bases 12 and part 3A with the layer 4 of the wig 10. The adhesion strength of the framework 12 and layer 4 was about 180 g/mm2and the strength of the fixing portion 3A and layer 4 was about 10 Gauss/mm2. The adhesion strength of the framework 12 and layer 4 was also ocena way of exfoliation manually and it was found that the layer 4 not exfoliate from the base 12, demonstrating that the glued without the possibility of exfoliation.
In addition, the strength of fixation of the bases 12 and part 3A was studied by the method of pulling of the hair 3 manually. The adhesion part FOR the base 12 is weaker than the adhesion bases 12 and layer 4, but the strength of fixation was sufficient for combing hair, etc.
[0055]. Sticky layer 4 and the possibility of peeling off the skin of the head was also very good. After wiping layer 4 water it again can be glued to the scalp, and, moreover, such a bonding and separation could be carried out continuously dozens of times, thus confirming the possibility of exfoliation of the layer 4. Therefore, because the wig you can wear and take either daily, or if you want to wear constantly for several days, it is hygienic and preferred from a practical point of view.
[0056]. When testing watched the appearance of the bearer of the wig 10 and noticed the reflection of light from the layer 4. In addition, when the head of the carrier of the wig 10 watched another subject, he did not notice the presence of the layer 4, the color of the scalp media wig was visible through the wig, visible Shine and pattern of wrinkles, similar to the scalp, consequently, the wig 10 is not noticeable when worn and gives Ho is OSI appearance.
[0057]. Above was a variant of implementation of the present invention, but it does not restricted and can be appropriately modified within the scope of the present invention. For example, as a layer 4 was shown urethane gel, but as soon as it provides the strength of fixation basics 2 or 12 and part 3A inserted into this framework, and the capacity for subsequent detachment from the area of the scalp, can be properly selected adhesive for a wig for its manufacture. In addition, the additive that eliminates Shine, not limited to silica, and can be used another Supplement. In addition, individual numerical values shown in the above embodiments can be modified properly.
