Abstract

A detachable carpet is provided. The detachable carpet includes a carpet surface layer and an adhesive anti-skid layer, and the carpet surface layer and the adhesive anti-skid layer are detachably connected. The carpet surface layer includes a surface layer and a sticky layer, and the surface layer is arranged at a top end of the carpet surface layer. Bent protruded monofilaments are distributed on a lower surface of the sticky layer, and lumps are formed at the tops of the monofilaments after the monofilaments are melted/softened. The adhesive anti-skid layer includes a hooking surface layer and an anti-skid layer, and the anti-skid layer is arranged at a bottom of the adhesive anti-skid layer. After the protruded monofilaments on the lower surface of the sticky layer are subjected to thermal treatment, the top ends of the protruded monofilaments are melted/softened to form small lumps.

Description

CROSS REFERENCE TO THE RELATED APPLICATIONS This application is the national phase entry of International Application No. PCT/CN2022/103555, filed on Jul. 4, 2022, which is based upon and claims priority to Chinese Patent Application No. 202221122673.0, filed on May 11, 2022, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The present invention relates to carpets in the textile industry, and particularly relates to a detachable carpet. BACKGROUND 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 type of ground mat is washable, but it will become 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 typically cannot replace the carpet seasonally at will as needed. Therefore, a carpet is needed which not only has the functions of 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, which connects 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). 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-shaped cushion has a great destructive effect to soft loop-pile cloth, and the connecting force is greatly reduced after multiple times of use. Patent literature CN209932326U 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 the pressure plate block is hinged and fixed with one end of the notch, 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 an 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, a 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 an uncomfortable feeling. SUMMARY To overcome the defects in the prior art, the present invention is intended to provide a detachable carpet. The objective of the present invention can be achieved by the following technical solution: the present invention provides a
