[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Embodiment 1

[0020] Combination Figure 1 and Figure 2 The present embodiment is described in detail. The present embodiment involves a three-proof sofa fabric, which comprises a three-proof fabric layer 1, a tear-resistant fabric layer 2, an anti-mite and antibacterial fabric layer 3 and a waterproof fabric layer 4.

[0021] The three-proof fabric layer 1 is formed by core-spun yarn woven in plain or twill weave, the core-spun yarn includes a first core yarn and a first wrapping yarn wrapped around the outside of the core yarn, the core-spun yarn includes ultra-high molecular weight polyethylene filaments, and the wrapping yarns are nylon 6 filaments; the surface of the fiber in the three-spinning fabric layer 1 is attached with a nano three-proof finishing agent. The fineness of the nylon 6 filament used is 75D / 144F. The ultra-high molecular weight polyethylene filament used has high strength and anti-cutting effect, so that the three-proof fabric layer 1 has anti-cutting effect.

[0022] Furthermore, the tear-resistant fabric layer 2 is a planar three-dimensional fabric woven by the first yarn 21, the second yarn 22 and the third yarn 23 at an angle of 60°; the first yarn 21 and the second yarn 22 are ultra-high molecular weight polyethylene filaments, and the third yarn 23 is an ultra-high molecular weight polyethylene filament and a hot-melt filament twisted in parallel. Conventional fabrics are generally interwoven with mutually perpendicular warp yarns and weft yarns. This orthogonal planar fabric can only effectively transfer loads in the direction parallel to the yarns. When the force direction is not along the warp or weft arrangement direction, the ability of the fabric to resist deformation and damage is greatly reduced, and it is difficult to meet the mechanical performance requirements of textiles. The planar three-dimensional fabric is formed by the first yarn 21, the second yarn 22, and the third yarn 23 interwoven at a 60° direction. The bearing capacity of the fabric in all directions is relatively uniform. Regardless of whether the force direction is along the yarn direction, it is not easy to cause the phenomenon of local stress concentration in the planar two-way fabric causing the yarn to break. It has good dimensional stability and strong resistance to deformation and damage.

[0023] The first yarn 21, the second yarn 22 and the third yarn 23 all use ultra-high molecular weight polyethylene filaments, which have high strength and cut-resistant effects. The third yarn 23 also uses hot-melt filaments, which will bond with other yarns after heat treatment, thereby further improving the dimensional stability and tear resistance of the fabric. The hot-melt filaments used are ES filaments.

[0024] Furthermore, the anti-mite and anti-bacterial fabric layer 3 is interwoven with copper-modified anti-bacterial and anti-mite polyamide 6 fiber yarns. The waterproof fabric layer 4 includes a composite water-repellent polyester spunlace non-woven fabric and a waterproof breathable membrane, and the waterproof breathable membrane is located on one side close to the anti-mite and anti-bacterial fabric layer 3.

[0025] Embodiment 2

[0026] Combination Figure 3, this embodiment is described in detail. The three-proof sofa fabric involved in this embodiment is different from that in the first embodiment in that: a flame-retardant fabric layer 5 is arranged between the tear-resistant fabric layer 2 and the anti-mite and antibacterial fabric layer 3; the flame-retardant fabric layer 5 includes a polyacrylonitrile pre-oxidized fiber non-woven fabric, and flame-retardant microcapsules contained in the internal gaps of the polyacrylonitrile pre-oxidized fiber non-woven fabric. In this embodiment, a needle-punched non-woven fabric is selected, which is formed by consolidating fibers and has gaps between the fibers.

[0027] Furthermore, the flame retardant microcapsule includes a capsule wall and a flame retardant gas in a packaging space formed by the capsule wall; the capsule wall is ethylene-vinyl acetate copolymer. The flame retardant gas is nitrogen or carbon dioxide, and nitrogen is selected in this embodiment. When the flame retardant microcapsule burns, the capsule wall is destroyed, thereby releasing the internal gas, which can dilute the concentration of oxygen at the combustion site, thereby achieving a flame retardant effect.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
