[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, a wear-resistant and flame-retardant sofa fabric includes: a base fabric layer 1 and raised particles 8. The raised particles 8 are numerous and evenly distributed on the inner side of the base fabric layer 1, made of rubber, and are soft and durable. The raised particles 8 are located on the inner side of the sofa fabric, giving it a textured feel and providing a certain massage effect when sitting on it.

[0027] Preferably, such as Figure 2 As shown, the protrusion 8 has a dome-shaped structure and a central groove 9 is formed by recessing along its diameter. The protrusion 8 is fixedly connected to the base fabric layer 1 by stitching, with the stitching fitting into the central groove 9. A flame-retardant finishing agent layer is attached to the surface of the base fabric layer 1 to improve its flame retardancy. The flame-retardant finishing agent layer is obtained by impregnating the base fabric layer 1 with a flame-retardant finishing liquid.

[0028] Base layer 1 is composed of interwoven warp and weft yarns, with the warp yarns being the first composite yarn, such as... Figure 3 As shown, the first composite yarn includes a core filament and a wrapping filament spirally wound around the core filament. The core filament is a polyester-spandex core-spun yarn, and the wrapping filament is the first core-spun yarn. Specifically, the core yarn of the polyester-spandex core-spun yarn is spandex filament 7, and the wrapping yarn is antibacterial polyester fiber yarn 5; the wrapping yarn of the first core-spun yarn is flame-retardant polyester fiber yarn 2, and the core yarn is antistatic filament 3. The polyester-spandex core-spun yarn not only possesses excellent elasticity and strength but also antibacterial properties, improving the hygiene of the sofa surface. The first core-spun yarn has advantages such as flame retardancy, antistatic properties, high strength, and wear resistance, giving the sofa fabric excellent performance and rich functionality.

[0029] The weft yarns include the first weft yarn and the second weft yarn. The first and second weft yarns are overlapping weft yarns, forming a double weft structure with the warp yarns. The first weft yarn is the inner weft, and the second weft yarn is the outer weft. The inner weft faces the inside of the sofa, and the outer weft faces the outside of the sofa.

[0030] The first weft yarn is the second composite yarn, such as Figure 4As shown, the second composite yarn includes a core yarn and a wrapping yarn spirally wound around the core yarn. The core yarn is a polyester-spandex core-spun yarn, and the wrapping yarn is the second core-spun yarn. The polyester-spandex core-spun yarn is the same as that of the first composite yarn. The wrapping yarn of the second core-spun yarn is flame-retardant polyester fiber yarn 2, and the core yarn is antibacterial filament 4. The difference between the second core-spun yarn and the first core-spun yarn is that the second core-spun yarn abandons the antistatic ability and instead enhances the antibacterial ability of the fabric. Combined with the polyester-spandex core-spun yarn, the antibacterial properties of the fabric can be further improved.

[0031] The second weft yarn is the third composite yarn, such as Figure 5 As shown, the third composite yarn includes a core yarn and a wrapping yarn spirally wound around the core yarn. The core yarn is a polyester-spandex core-spun yarn, and the wrapping yarn includes flame-retardant polyester fiber yarn 2 and flame-retardant viscose fiber yarn 6. The flame-retardant polyester fiber yarn 2 and flame-retardant viscose fiber yarn 6 are spirally wound around the polyester-spandex core-spun yarn in a 1:1 ratio. The polyester-spandex core-spun yarn is the same as described above. The flame-retardant polyester fiber yarn 2 gives the outer and weft fabrics basic properties of abrasion resistance and flame retardancy; the flame-retardant viscose fiber yarn 6 has good flame retardancy and softness and comfort, which can improve the softness and comfort of the sofa fabric surface. Preferably, the fineness of the flame-retardant polyester fiber yarn 2 is greater than that of the flame-retardant viscose fiber yarn 6, so that the flame-retardant polyester fiber yarn 2 protrudes from the flame-retardant viscose fiber yarn 6, which can protect the flame-retardant viscose fiber yarn 6, thereby improving the abrasion resistance of the flame-retardant viscose fiber yarn 6.

[0032] Preferably, the preparation process of flame-retardant polyester fiber yarn 2 includes: 1. Under nitrogen protection, using sodium acetate as an ether inhibitor and triphenyl phosphate as an anti-aging agent, phenylphosphine acid and ethylene glycol are added to a reaction vessel, and an esterification reaction is carried out at a reaction temperature of 155-165℃ for a reaction time of 1.0-2.5h. After the reaction, water vapor is removed under vacuum at 200℃ with a vacuum degree of 500Pa for a removal time of 0.5-1.0h to prepare hydroxyethyl phenylphosphine ester; 2. Using dioxane as a solvent, concentrated sulfuric acid with a mass fraction of 98% as a catalyst, sodium acetate as an ether inhibitor, and triphenyl phosphate as an anti-aging agent, hydroxyethyl phenylphosphine ester and guanidinoacetic acid are added to a reaction vessel, and the reaction is carried out at a reaction temperature of 180-200℃ for a reaction time of 1.5-2.0h. Esterification reaction was carried out. After the reaction, water vapor was removed under vacuum at 220℃ with a vacuum degree of 500Pa and a removal time of 0.5-1.0h to prepare a primary flame retardant. 3. Using the primary flame retardant, nano magnesium hydroxide and cyclic polybutylene terephthalate as raw materials, flame retardant PBT material was obtained by extrusion granulation at a melting temperature of 195-210℃ using a melt blending method. 4. Flame retardant PBT material and polyester chips were melt-mixed and melt-spun through a circular spinneret to obtain flame retardant polyester filament. The spinning process was as follows: winding speed of 3800-4400 m / min, ring blower speed of 0.25-0.45 m / min, ring blower length of 110-175 cm, stretch ratio of 2.1-3.4 times, and winding tension of 25-37 cN.

[0033] Among them, the antistatic filament 3 consists of a core filament and a sheath: the outer surface of the core filament is provided with a conductive particle layer, and a sheath is covered on the outer surface of the conductive particle layer. The sheath is made by sizing with a nitrogen-phosphorus flame retardant liquid. The core filament is a polyester filament, and the conductive particle layer is composed of silver particles, copper-nickel particles, or nickel-chromium particles with a particle size of 0.5-300 nanometers.

[0034] Preferably, the antibacterial filament 4 is formed by twisting antibacterial polyester filament and far-infrared polyester filament together. The antibacterial polyester filament is obtained by modifying polyester. The far-infrared polyester filament includes 1-10% far-infrared radiating ceramic powder, which is composed of 60% silicon dioxide, 20% zirconium dioxide, 15% ferric oxide, and 5% copper oxide. The preparation method is as follows: first, the ceramic powder is mixed with aliphatic polyester to obtain far-infrared masterbatch, and then the masterbatch and chips are melt-extruded.

[0035] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
