1. A detachable carpet, comprising:
a carpet surface comprising a surface layer and a bottom three-dimensional mesh fabric structure layer, and
an anti-slip mat comprising a bottom anti-slip and water-repellent layer and an upper bonding layer; wherein
the upper bonding layer is a single-sided structure layer formed by cutting a middle of a three-dimensional mesh fabric structure layer and is integrally knitted by using 20 D-120 D polyester monofilament yarn, the three-dimensional mesh fabric structure layer comprising an upper warp-knitted mesh fabric layer, a lower warp-knitted mesh fabric layer, the thickness of the three-dimensional mesh fabric structure layer is 2 mm-20 mm, a plurality of polyester, polypropylene or nylon monofilament protrusions arranged vertically in the middle to connect the upper warp-knitted mesh fabric layer and the lower warp-knitted mesh fabric layer, and a height of each of the plurality of polyester, polypropylene or nylon monofilament protrusions on the upper bonding layer is 5 mm-10 mm;
the bottom three-dimensional mesh fabric structure layer of the carpet surface comprises an upper warp-knitted mesh fabric layer, a lower warp-knitted mesh fabric layer, and a plurality of polyester, polypropylene or nylon monofilaments, wherein the plurality of polyester, polypropylene or nylon monofilaments are arranged vertically in a middle of the bottom three-dimensional mesh fabric structure layer to connect the upper warp-knitted mesh fabric layer and the lower warp-knitted mesh fabric layer; and
the plurality of polyester, polypropylene or nylon monofilament protrusions of the upper bonding layer are inserted into meshes of the bottom three-dimensional mesh fabric structure layer creating a bonding strength between the upper bonding layer and the bottom three-dimensional mesh fabric structure layer that has a peel force between 1.325 and 1.467 Newton after subjecting the detachable carpet with a size of 5 cm×20 cm to be rolled twice with a 6 kg roller; and wherein
a washable and movable double-sided adhesive tape made of polyurethane and acrylic is provided on a periphery or four top corners of the bottom three-dimensional mesh fabric structure layer of the carpet surface.
