Abstract

A detachable carpet includes a carpet surface and an anti-slip mat. The carpet surface includes a surface layer and a bottom three-dimensional mesh fabric structure layer. The anti-slip mat includes a bottom anti-slip and water-repellent layer and an upper bonding layer, and the bonding layer is a single-sided fabric on which are arranged a plurality of polyester, polypropylene or nylon monofilament protrusions. The protrusions can be inserted into corresponding meshes of the three-dimensional mesh fabric structure layer. The bonding layer of the anti-slip mat of the present invention adopts a single-sided structure layer formed by cutting the middle of the three-dimensional mesh fabric structure layer, or a single-sided fabric that is made of at least 20 D monofilament and provided with protrusions. The 20 D-120 D polyester, polypropylene or nylon monofilament on the bonding layer forms thick and rigid protrusions with a certain stiffness.

Claims (22)

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.

2. The detachable carpet according to claim 1 , wherein,

an included angle between each of the plurality of polyester, polypropylene or nylon monofilament protrusions and the single-sided fabric is 40°-90°.

3. The detachable carpet according to claim 2 , wherein,

an area of a single mesh on a single-sided warp-knitted mesh fabric of the single-sided structure layer of the upper bonding layer ranges from 0.2 square millimeters to 100 square millimeters.

4. The detachable carpet according to claim 2 , wherein,

the upper bonding layer is a single-sided tufted fabric knitted by using 20 D-120 D polyester, polypropylene or nylon monofilaments, or

the upper bonding layer is a single-sided flocked fabric knitted by using the 20 D-120 D polyester, polypropylene or nylon monofilaments.

5. The detachable carpet according to claim 1 , wherein,

the upper bonding layer is a single-sided tufted fabric knitted by using 20 D-120 D polyester, polypropylene or nylon monofilaments, or

the upper bonding layer is a single-sided flocked fabric knitted by using the 20 D-120 D polyester, polypropylene or nylon monofilaments.

6. The detachable carpet according to claim 1 , wherein,

a thickness of the bottom three-dimensional mesh fabric structure layer of the carpet surface is 2 mm-20 mm;

an area of a single mesh on the upper warp-knitted mesh fabric layer or the lower warp-knitted mesh fabric layer of the carpet surface ranges from 0.2 square millimeters to 100 square millimeters.

7. The detachable carpet according to claim 1 , wherein,

an area of a single mesh on a single-sided warp-knitted mesh fabric of the single-sided structure layer of the upper bonding layer ranges from 0.2 square millimeters to 100 square millimeters.
