Patent Description:
There are two design methods for standard bath mats and carpets at present. One method is to design a towel-like bath mat, but this ground mat is not anti-skid and has potential safety hazards. Another method is to bond a material with an anti-skid function to a back surface of the carpet, and it is asserted that this ground mat is washable, but it will be separated or damaged or an upper fabric and a lower bottom back are separated once it is washed in a machine. Moreover, multi-applicability of the carpet is hindered due to tedious design and manufacture and high price of a conventional carpet. For example, a user is not allowed to replace the carpet seasonally at will as needed. Therefore, a carpet is needed, which not only has the functions of the conventional carpet, but also facilitates the user to separate the surface material of the carpet from a liner layer with anti-skid and water-repellent functions so as to disassemble and wash the surface material of the carpet.

In the prior art, there is a composite carpet connecting the carpet surface and the liner of the carpet by using a magic tape. The magic tape connects two layers of structures together with a secondary surface and a primary surface. One surface of the magic tape consists of fine and soft fiber loops (Loop) and the other surface is provided with hard hooks (Hook) with hooks. The two are firmly combined and can be separated only with a large force, owing to a large tensile force to separate the two. Thus, to connect the carpet surface and the liner of the carpet with the magic tape, as far as the soft carpet is concerned, the carpet may be damaged due to a large action force, and it is inconvenient to detach. The hard surface of the magic tape will reduce the using comfort level of the carpet. Moreover, the magic tape or a gravel cushion has a great destructive effect to soft loop-pile cloth, and the connecting force is greatly reduced after multiple times of use.

Through retrieval, a patent literature <CIT> discloses an easily cleaned detachable carpet, including a base, where a groove for placing the carpet is dug in an upper surface of the base, cuboid limiting plates are welded and fixed to left and right sides of the groove, there are certain gaps between the limiting plates and the bottom of the groove, cuboid notches penetrating the limiting plates are dug in the limiting plates, cuboid pressure plate blocks are placed in the notches, one end of each of the pressure plate blocks is hinged and fixed with one end of each of the notches, the other end of the pressure plate block is provided with a bolt hole, a primary paste buckle is adhered and fixed to a bottom surface of the pressure plate block, a secondary paste buckle is adhered and fixed to the primary paste buckle, the secondary paste buckles are sewed on left and right sides of the upper surface of a bottom layer of the carpet, a cloth bag is sewed on the upper surface of the bottom layer, a zipper groove is dug in the side surface of the cloth bag, a zipper is mounted in the zipper groove, a bag core is placed in the cloth bag, an anti-skid layer is sewed above the cloth bag, and a suede layer of the carpet is sewed on the anti-skid layer. The prior art has the deficiency that by adopting a technical means of the paste buckle similarly, the paste buckle is easily damaged in the detaching and cleaning processes and deforms due to factors such as temperature, so that the service life of the carpet is affected severely.

In the prior art, the plurality of vertically downward protrusions are also additionally arranged below the carpet surface layer, the downward protrusions can be inserted into the mesh gaps of the three-dimensional mesh fabric structure layer on the carpet mat, and the carpet can be combined with the gap structures of the three-dimensional mesh fabric structure layer. However, stabs formed by the polyester, polypropylene or nylon monofilaments in the anti-skid mat layer may be inlaid into the mesh gaps of the three-dimensional mesh fabric structure layer after repeated used. The carpet is susceptible to deformation after long-term use, and hands are easily pricked in terms of hand feeling when it is separated from the lower layer, which brings people uncomfortable feeling. <CIT> discloses a detachable carpet according to the preamble of claim <NUM>. The detachable carpet is provided with a fastening system for detachably securing the mat to the base tray. The fastening system has at least one mushroom-type hook fastener component attached to one or the other of the backing layer of the mat or the tray. A second component of the fastening system, which may be a mushroom-type hook fastener, loop strip or a fabric capable of being penetrated by the hooks of the first component, is attached on the backing layer of the mat or tray, opposite the first component. <CIT> discloses a hook-and-loop fastener for preventing floor mats from moving. The hook-and-loop fastener comprises a hook-and-loop fastener having engaging elements, the tip of which is formed in a hook, arrowhead or mushroom shape, implanted approximately upright on one side of a base material; and a removable layer laminated so as to form the uppermost layer on the other side of the base material of the hook-and-loop fastener, the removable layer being made of a removable adhesive layer. <CIT> discloses a non-slip mat which comprises a carpet surface layer, a middle layer and a non-slip layer, wherein the upper surface of the middle layer is bonded with the carpet back of the carpet surface layer; the non-slip layer comprises a plurality of suction cups evenly distributed on the lower surface of the middle layer; and the suction cups and the lower surface of the middle layer are pressed and solidified into a whole during injection molding. The upper surface of the middle layer is distributed with lumps formed by the scattered fibers being heated, and Velcro is sewn on the lumps on the upper surface of the middle layer. <CIT> discloses methods including use of heat and chemicals for converting loops upstanding from a base fabric into hook members suitable for use in hook and loop fasteners. A base fabric having a series of looped piles in regular rows upstanding therefrom is used as a starting material. The rows of loops first are held by rods inserted therein and, thereafter platens or rollers are to provide heat and pressure caused to pass over the upper ends of the rods thus effecting the conversion of the loops into various hooked forms. Chemical means in combination with mechanical pressure are also used for converting loops into hooked forms. <CIT> discloses a carpet pad. The carpet pad comprises an upper hooking layer and a lower anti-slip layer; the upper surface of the hooking layer is distributed with curved raised monofilaments, and the top has lumps formed by the melting/softening of the raised monofilaments.

To overcome the defects in the prior art, the present invention is intended to provide a detachable carpet according to claim <NUM>.

The objective of the present invention can be achieved by the following technical solution:.

The protruded monofilaments are distributed on the lower surface of the sticky layer. After thermal treatment, the top ends of the protruded monofilaments are melted/softened to form small lumps. Meanwhile, the monofilaments subjected to thermal treatment have certain curvature, inclination to form hooked spines which can be hooked with gaps of various adhesive anti-skid layers therebelow to gain a locking effect.

As an implementation mode of the present invention, preferably, a supportive fabric bonding layer is placed between the surface layer and the sticky layer. The supportive layer of a fabric structure can improve the supporting property, the dimensional stability, the comfort and the smoothness of the carpet.

As an implementation mode of the present invention, preferably, the surface layer includes one of a surface layer of a velvet pile structure, a surface layer of a loop pile structure, a surface layer of a fleecy structure and a surface layer of a plain woven structure.

As an implementation mode of the present invention, preferably, the sticky layer includes one of a warp and weft woven layer, a layer of a woven structure, a layer of a tufting and cutting structure, a layer of a flocking structure, a layer of a fleecy structure and a layer of a fleecy nonwoven structure.

As an embodiment of the present invention, preferably, a height of the protruded monofilament is <NUM>-<NUM>. If the protruded monofilaments are too high, a displacement is generated under the action of an external force when the surface layer is hooked with the adhesive anti-skid layer. People walking on the carpet are easy to fall down. If the protruded monofilaments are too low, the protruded monofilaments cannot be hooked firmly when being combined with the surface layer.

As an embodiment of the present invention, preferably, a thickness of the protruded monofilament is 18DTEX-10000DTEX.

As an embodiment of the present invention, preferably, the hooking surface layer includes one of a layer of a fleecy fabric structure, a layer of a woven fabric with mesh gap structures, a layer of a fabric structure with a plurality of gaps, a layer of a nonwoven structure and a layer of a flexible material structure with meshes in surface.

As an implementation mode of the present invention, preferably, a supportive layer of a fabric structure is placed between the hooking surface layer and the anti-skid layer. The supportive layer of a fabric structure can improve the supporting property, the dimensional stability, the comfort and the smoothness of the carpet.

As an implementation mode of the present invention, preferably, the carpet surface layer further comprises a bonding layer, the bonding layer being arranged between the surface layer and the sticky layer.

The hooked spines of the present invention are short and can be hooked, so that the monofilaments need not to excessively penetrate into the hooking surface layer. The adhesive anti-skid layer can be thinner, too. In the using process, the stressed carpet surface will oppress the carpet, so that the hooks formed by the protruded monofilaments enter the adhesive anti-skid layer. Compared with uncurved monofilaments, the protruded monofilaments generate a better hooking effect. The protruded monofilaments are distributed on the back of the carpet surface, so that the carpet surface will not be damaged in the detaching process, and thus, the service life is long. Compared with a condition that the hooked spines are distributed on the upper surface of the adhesive anti-skid layer, it is suitable for an ultrathin carpet surface with different feelings of foot, particularly a domestic carpet. The protruded monofilaments will not pierce the carpet surface to affect the use feeling. When the carpet surface layer is replaced in a large area, the adhesive anti-skid layer as a base can be reserved as a carpet for facilitating subsequent pavement of the carpet surface layer. A condition that replacement of the carpet surface layer on the adhesive anti-skid layer is affected as the protrusions spreading all over the surface of the base prick the hand is avoided.
