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.

Claims (12)

1 . A detachable carpet, comprising a carpet surface layer and an adhesive anti-skid layer, wherein the carpet surface layer and the adhesive anti-skid layer are detachably connected;

the carpet surface layer comprises a surface layer and a sticky layer, wherein 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 tops of the bent protruded monofilaments after the bent protruded monofilaments are melted/softened, wherein the bent protruded monofilaments both are bent to form a J-structure and include the lumps at curved ends of the J-structure; and

the adhesive anti-skid layer comprises a hooking surface layer and an anti-skid layer, wherein the anti-skid layer is arranged at a bottom of the adhesive anti-skid layer.

2 . The detachable carpet according to claim 1 , wherein a supportive fabric bonding layer is placed between the surface layer and the sticky layer.

3 . The detachable carpet according to claim 1 , wherein the surface layer comprises 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.

6 . The detachable carpet according to claim 1 , wherein a thickness of each of the bent protruded monofilaments is 18DTEX-10000DTEX.

7 . The detachable carpet according to claim 1 , wherein the hooking surface layer comprises 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 a surface.

8 . The detachable carpet according to claim 1 , wherein the anti-skid layer is made from one of a thermoplastic elastomer layer, an ethylene-vinyl acetate (EVA)/polyurethane (PU)/polyvinyl chloride (PVC)/styrene butadiene rubber (SBR)/cross-linked polyethylene (XPE) foamed material layer, a nonwoven fabric layer, a hot melt adhesive layer, and a fabric layer with an anti-skid function.

9 . The detachable carpet according to claim 1 , wherein a supportive layer of a fabric structure is placed between the hooking surface layer and the anti-skid layer.

10 . The detachable carpet according to claim 1 , wherein the carpet surface layer further comprises a bonding layer arranged between the surface layer and the sticky layer.
