Description

Technical Field

[0001] The utility model relates to a three-proof composite fabric, belonging to the technical field of textile fabrics. Background Art

[0002] Sofa fabric is a general term for the main covering used in the sofa manufacturing process. It is widely used in modern people's lives and can be seen everywhere in homes, hotels, office conference rooms. When used as a sofa covering, sofa fabric needs to have an aesthetic effect, but people have higher and higher requirements for sofa fabrics, requiring sofa fabrics to have three-proof effects: waterproof, oil-proof and anti-fouling, which can effectively prevent pollutants such as water and oil from making the sofa fabric dirty. However, in the sofa preparation process, the fabric needs to be fixed to the sofa body, which requires the sofa fabric to have good tear resistance so that it is not easy to tear when used for a long time in a fixed position. How to improve the tear resistance of the three-proof fabric has become a problem to be solved. Utility Model Content

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] Combination Figure 1 , this embodiment is described in detail. The three-proof composite fabric involved in this embodiment includes a composite three-proof fabric layer 1, a tear-resistant fabric layer 2, a reinforced fabric layer 3 and an antibacterial and anti-mite fabric layer 4. And the fabric layers are bonded to each other by hot melt adhesive mesh.

[0020] The three-proof fabric layer 1 includes a fabric base layer 11 and a three-proof finishing agent coating 12 coated on the surface of the fabric base layer 11 on the side away from the tear-resistant fabric layer 2. The provision of the three-proof finishing agent coating 12 gives the composite fabric good three-proof functions of waterproof, oil-proof and anti-fouling, thereby improving the anti-fouling ability of the composite fabric, thereby reducing the pollution of water and oil to the sofa fabric.

[0021] Furthermore, the fabric base layer 11 is interwoven with high-strength flame-retardant polyester filaments. The high-strength flame-retardant polyester filaments make the fabric base layer 11 have high strength and good flame retardant effect. Specifically, in this embodiment, the fabric base layer 11 adopts a plain weave, which has more weave points, that is, the interweaving points of the warp and weft yarns, which can reduce the relative sliding of the warp or weft yarns.

[0022] The tear-resistant fabric layer 2 is a planar three-dimensional fabric; the planar three-dimensional fabric is woven from polyester filaments. Specifically, the planar three-dimensional fabric is a basic weave planar three-dimensional fabric, a double plain weave planar three-dimensional fabric, or a basic square weave planar three-dimensional fabric. In this embodiment, the basic weave planar three-dimensional fabric is selected.

[0023] The reinforced fabric layer 3 is interwoven with high-strength parallel-twisted yarns as warp and weft yarns, and the high-strength parallel-twisted yarns include parallel-twisted high-strength polyester filaments and PTFE split film filaments. The high-strength polyester filaments and PTFE split film filaments can make the reinforced fabric layer 3 have higher strength, and the PTFE split film filaments have thermal stability at high temperatures, which can make the three-proof composite fabric have good dimensional stability and reduce the deformation of the fabric during the production process.

[0024] Furthermore, the antibacterial and anti-mite fabric layer 4 is a warp-lined and weft-lined warp knitted fabric woven with antibacterial and anti-mite yarns. The warp-lined and weft-lined warp knitted fabric refers to a warp-lined and weft-lined warp knitted fabric with yarns not involved in loop formation inserted between the loops and extension lines of the warp knitted fabric, which can improve the dimensional stability of the knitted fabric.

[0025] Furthermore, the antibacterial and anti-mite yarn is an antibacterial and anti-mite Luka fiber yarn. The antibacterial and anti-mite Luka fiber yarn has antibacterial, anti-mildew and anti-mite effects. The antibacterial and anti-mite Luka fiber yarn is used in conjunction with the first antibacterial and anti-mite yarn 12 so that the fabric body has good antibacterial, anti-mildew and anti-mite effects.

[0026] Embodiment 2

[0027] Combination Figure 2 , this embodiment is described in detail. The three-proof composite fabric involved in this embodiment is different from the first embodiment in that a microporous membrane 5 is composited on the side of the antibacterial and anti-mite fabric layer 4 away from the reinforced fabric layer 3. The microporous membrane 5 can be a TPU microporous membrane or a PTFE microporous membrane. In this embodiment, a PTFE microporous membrane is selected.

[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.
