Patent Description:
Excellent moisture permeability is one of the common goals of the current research and development of clothing, especially sportswear. In the industry, dense vent structures or changing the composition ratio of fabrics are usually used to improve the moisture absorption rate and air permeability, etc. However, the function of such air permeability is fixed and cannot be adjusted according to the state of perspiration and non-perspiration, so it is easy to catch cold in cold wind. There are also designs that can be opened and closed by opening the opening and installing a zipper at the opening, but it needs manual operation. Besides, the clothes are not light enough and the appearance is not simple enough after adding a zipper. How to prepare clothes that can automatically adjust the breathable and moisture permeable structure according to the state of human perspiration or not is an urgent problem to be solved at present.

Patent document <CIT> discloses an automatic opening composite material and garment. The automatic opening composite material comprises a fabric layer, a notch, and a composite layer group. Arranged on the fabric layer, the composite layer group includes a hydrophilic functional layer with a higher moisture absorption rate than common materials, a hydrophobic functional layer with a lower moisture absorption rate than common materials, and a glue film for bonding the composite layer group into a cohesive unit. In a dry environment, the notch remains closed; however, in a humid environment, the notch opens, allowing for automatic ventilation or cooling.

Patent document <CIT> discloses a process for providing ventilation incisions on flexible substrates. The process involves treating the flexible substrate with a chemical or a combination of chemicals that react to environmental factors, thereby regulating the functioning of the ventilation points on the substrate. The process includes substrate selection, chemical selection and preparation, application of the chemical on the substrate, and creation of ventilation incisions on the substrate. The chemical or combination of chemicals used includes those that react to environmental factors such as temperature, moisture, and light. The reaction of the chemical or combination of chemicals causes the ventilation incisions on the flexible substrate to deform and adapt for ventilation.

Therefore, the present invention proposes a new scheme to prepare a garment that can automatically adjust the breathable and breathable structure according to the state of human sweating or not.

For a clearer representation, the following is a detailed description of the present invention in combination with the accompanying drawings and specific embodiments.

Referring to <FIG>, the present invention provides a preparation method of a garment with automatic opening, which first prepares a garment opening preform <NUM>, and then uses the garment opening preform <NUM> to prepare a garment with automatic opening <NUM>.

Specifically, the preform <NUM> includes a functional layer <NUM>, a positioning layer <NUM>, a first connecting layer <NUM>, a second connecting layer <NUM>, and an adhesive layer <NUM>. Therein, with reference to <FIG>, the functional layer <NUM> has a predetermined shape and size, and a plurality of functional layers <NUM> are attached to a portion of an area of the inner side <NUM> of the positioning layer <NUM>, the plurality of functional layers <NUM> being evenly spaced on the inner side <NUM> of the positioning layer <NUM>. Referring to <FIG>, a first connecting layer <NUM> is provided between the functional layer <NUM> and the positioning layer <NUM> for connecting the functional layer <NUM> to the positioning layer <NUM>, and a second connecting layer <NUM> is provided on at least part of the area of the inner side <NUM> to which the functional layer is not connected, for connecting the preform <NUM> to the garment to be opened when the open garment is subsequently made, in order to position the opening for the garment to be opened. An adhesive layer <NUM>, attached to the side of the functional layer <NUM> away from the positioning layer <NUM>, is used to subsequently connect the functional layer <NUM> to the garment fabric layer <NUM>, the shape and size of the adhesive layer <NUM> being the same as or compatible with the functional layer <NUM>. The preform <NUM> contains the adhesive layer <NUM>, and the shape and size of the adhesive layer <NUM> is the same as the predetermined shape and size of the functional layer <NUM> can be more accurate and convenient to use when subsequently connecting with the garment fabric layer, and avoid the problems of inconvenient positioning, increased labor and adhesive material residue when covering the adhesive layer directly on the garment fabric layer.

When it is necessary to open the garment, it is only necessary to connect the preforms <NUM> with the area of the garment to be opened and make the incision according to the position of the functional layer <NUM>, without using the machine to line up the garment one by one and then make the incision, which is convenient and simple, easy to adjust (connection position) and more accurate positioning, providing a convenient and accurate template role for the garment opening, which is ready to use.

Functional layer <NUM>, is a hydrophilic material layer made of hydrophilic material, or hydrophobic material layer made of hydrophobic material. The hydrophilic material has a higher moisture absorption rate than an ordinary garment fabric, such as a polyurethane/polyethylene composite film or cotton; the hydrophobic material has a lower moisture absorption rate than an ordinary garment fabric, such as polyester or nylon. The functional layer <NUM> cooperates with the garment fabric layer <NUM> having the incision stitch, and the difference in moisture absorption between the functional layer <NUM> and the garment fabric layer <NUM> is used to make the incision stitch open or close automatically according to the human body sweating or not, so as to improve the breathability and moisture permeability performance and enhance the wearing comfort.

Referring to <FIG>, in a specific embodiment, the cross-sectional shape of the plurality of functional layers <NUM> is semi-circular and of the same size. It is easy to understand that the shape, number, size and arrangement distribution of the functional layer <NUM> are designed according to the opening design of the garment to be opened, which can be changed according to the garment design needs, and can be a uniform shape, a uniform size, or a variety of shapes, a variety of sizes, and can be a plurality of evenly spaced arrangement distribution, or can be irregularly arranged. For example, the functional layer of the uniform semicircle in this embodiment corresponds to the shape of the garment opening seam as a uniform circular line (see <FIG> later). In another embodiment, the cross-section of the plurality of functional layers <NUM> may also be uniformly triangular (not shown), in which case their corresponding garment opening seams are shaped as uniform V-shaped lines. In other embodiments, the shape of the plurality of functional layers <NUM> may also be horseshoe, crescent, star, or any combination thereof, etc. In one embodiment, the number of functional layers <NUM> is a plurality, which allows the cutouts for the garment to be opened to be produced in bulk; in other embodiments, the number of functional layers <NUM> may also be one, such as an individual unique or prominent shape design.

As a further improvement, the adhesive layer <NUM> may also have a protective film (not shown in the FIG. s) attached to the side of the adhesive layer <NUM> away from the positioning layer <NUM> so that the functional layer <NUM> and the adhesive layer <NUM> are not damaged before subsequent attachment to the garment fabric layer <NUM>.

The positioning layer <NUM> is used to carry the functional layer <NUM>, which may be a transparent plastic film smooth on both sides for easy observation during subsequent attachment to the garment fabric, or it may be a release paper. The positioning layer <NUM> is connected to the functional layer <NUM> by a first connecting layer <NUM>, which is for example a low viscosity adhesive layer, and a second connecting layer <NUM> is attached to the part of the inner side <NUM> of the positioning layer <NUM> that is not covered/connected with a functional layer.

Referring to <FIG>, in one embodiment, the first connecting layer <NUM> and the second connecting layer <NUM> are the same layer, which are joined together and cover the entire inner side. This is convenient to make and can make the subsequent paste positioning better. As a further improvement, the positioning layer <NUM> and the first connecting layer <NUM> and the second connecting layer <NUM> can also be a one-piece product, for example, a commercially available PET film with low adhesion, so that raw materials are easy to obtain and easy to implement.

When the first connecting layer <NUM> and the second connecting layer <NUM> are the same layer, and both are integrated to form a monolithic connecting layer and cover the whole nner side; the preparation of the preform <NUM> includes the following steps:.

In other embodiments, the second connecting layer <NUM> may also be attached to only a portion of the area on the inner side <NUM> that does not have the functional layer <NUM> attached to it, i.e., the area on the inner side <NUM> that does not have the first connecting layer <NUM> attached to it does not all have the second connecting layer <NUM> attached to it, as long as it is able to achieve attachable positioning with the subsequent garment fabric. At this time, the second connecting layer <NUM> can be distributed on the four corners or edges of the inner side <NUM> (can be shown with reference to the blank area in <FIG>), and the first connecting layer <NUM> and the second connecting layer <NUM> can be made of the same material, or can be made of different materials.

When the first connecting layer <NUM> and the second connecting layer <NUM> are not the same layer, the preparation of the preform <NUM> comprises the following steps:.

In the present invention, with reference to <FIG>, the preparation of a garment with automatic opening <NUM> using the garment opening preform <NUM> comprises the following steps: fixing the garment opening preform <NUM> to the fabric layer <NUM> of the garment to be opened by means of the second connecting layer <NUM>, laminating the fabric layer <NUM>, the adhesive layer <NUM> and the functional layer <NUM> into a composite body, laser engraving the opening of the composite body so that the fabric layer <NUM> to create a penetrating incision stitch in the fabric layer; remove the positioning layer, the second connecting layer and the first connecting layer, that is.

Specifically, the above steps can be further refined as follows:.

Referring to <FIG>, a garment with automatic opening <NUM> includes a functional layer <NUM> of the preform <NUM>, a garment fabric layer <NUM> and an adhesive layer <NUM>, which is provided between the functional layer <NUM> and the garment fabric layer <NUM> to achieve mutual bonding. The adhesive layer <NUM> may be a hot melt adhesive film, which may be one of polyamide, polyester, polyethylene and polyester amide, such as Bemis adhesive film.

The garment fabric layer <NUM> is provided with incision stitch <NUM> throughout, the number of incision stitch <NUM> is the same as the number of functional layers <NUM>, the shape of the incision stitch <NUM> is the same as one side or two interconnected sides of the functional layer <NUM>, and the open seam position of the incision stitch <NUM> corresponds to the side distribution position. For example, the functional layer <NUM> has a semicircular cross-section, corresponding to the incision stitch <NUM> as a circular line (see <FIG>); or the functional layer <NUM> has a triangular cross-section, and the incision stitch is a V-shaped line (not shown). The seam width of the incision stitch is <NUM>-<NUM>, for example <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, <NUM>, preferably <NUM>.

In a specific embodiment, the functional layer <NUM> can be attached to the side of the garment fabric layer <NUM> near the human skin, when the functional layer <NUM> is a hydrophilic material layer, the hydrophilic material layer has a higher moisture absorption rate than the garment fabric layer <NUM>, the hydrophilic material layer is for example PU high permeability film; when the human body sweats, the hydrophilic material layer near the incision stitch <NUM> absorbs moisture and expands and elongates more than the garment fabric layer <NUM>. Thus, it is pulled apart by the garment fabric layer <NUM>, which is located on the outside with a short elongation, making the incision stitch <NUM> open automatically, increasing the contact area between the surface of human skin and the outside air, accelerating the evaporation of sweat and heat dissipation; when the human body does not sweat and returns to a dry state, the pulling force disappears and the incision stitch <NUM> closes automatically again.

In another specific embodiment, the functional layer <NUM> can also be attached to the side of the garment fabric layer <NUM> away from the human skin, when the functional layer <NUM> is a hydrophobic material layer, the hydrophobic material layer has a lower moisture absorption rate than the garment fabric layer <NUM>, when the human body sweats, the garment fabric layer <NUM> near the incision stitch <NUM> absorbs moisture and expands and elongates more than the hydrophobic material layer, thus being located on the outside with a short elongation of the hydrophobic, which makes the incision stitch <NUM> automatically open. When the body does not sweat and returns to the dry state, the pulling force disappears and the incision stitch <NUM> closes automatically.

The garment provided by the present invention can automatically open (can automatically open the incision stitch) through the functional layer with the garment fabric layer, using the difference in moisture absorption rate between the functional layer and the garment fabric layer, so that the incision stitch can automatically open or close according to the human body sweating or not, improving the breathable and moisture permeable performance and enhancing the wearing comfort.
