Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

Example (b):

a wear-resistant warp-knitted polyester sofa fabric is shown in figures 1 and 2 and comprises a sofa fabric body. The sofa cloth body comprises a chenille layer 2, a terylene warp knitting layer 12, a fabric flame-retardant layer and an expansion layer 5. The terylene warp-knitted layer 12 is positioned on the lower surface of the chenille layer 2, the fabric flame-retardant layer is positioned on the lower surface of the terylene warp-knitted layer 12, and the expansion layer 5 is positioned on the lower surface of the fabric flame-retardant layer. The terylene warp-knitted layer 12 is mutually bonded with the fabric flame-retardant layer and the chenille layer 2 through pressure-sensitive adhesive.

The fabric flame-retardant layer comprises a polyester warp tape 1, a polyester weft tape 3 and a glass fiber grid layer 4, the polyester warp tape 1 and the polyester weft tape 3 are interwoven to form a base fabric intersection 7, the polyester warp tape 1 and the polyester weft tape 3 are bonded at the intersection, and are soaked in a phosphorus-nitrogen liquid flame retardant in advance and dried to perform flame-retardant treatment. The glass fiber mesh layer 4 is fixedly arranged below the polyester warp tape 1 and the polyester weft tape 3, the mesh number of the glass fiber mesh layer 4 is 6 meshes or 8 meshes, and the mesh number of the glass fiber mesh layer 4 is 6 meshes in the embodiment. Each of the polyester warp tapes 1 and the polyester weft tapes 3 respectively comprises three parallel polyester cords, the upper surface of the polyester cord in the middle is provided with a metal wire 11, the metal wire 11 is a stainless steel metal wire 11 or a copper metal wire 11, the metal wire 11 is the copper metal wire 11 in the embodiment, and the metal wire 11 is twisted and compounded with the polyester cord in the middle of the three parallel polyester cords.

The expansion layer 5 is made of non-woven fabrics, a concave hole is formed in the upper surface of the expansion layer 5, an expansion graphite block 6 is fixedly stuck in the concave hole, and the expansion graphite block 6 is located under a base cloth intersection 7. The surface of the expanded graphite block 6 close to the intersection 7 of the base cloth is in a sawtooth shape. The side of the intumescent layer 5 away from the flame retardant layer of the fabric is coated with an intumescent flame retardant coating 8, and the intumescent flame retardant coating 8 comprises an acid source, a carbon source and a gas source. The chenille layer 2 includes piles 9, and a rubber ring 10 for increasing friction is fitted around and adhered to a middle portion of each pile 9 in the longitudinal direction.

This embodiment is used: when the sofa fabric is ignited by external open fire, the terylene warp tapes 1 and the terylene weft tapes 3 which are soaked by the phosphorus-nitrogen liquid flame retardant and dried have the flame retardant effect, so that the further burning of the open fire can be prevented.
