[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, a flame-retardant car seat fabric includes: a surface layer 1, a middle layer 2 and an inner layer 3, and the middle layer 2 is arranged between the surface layer 1 and the inner layer 3.

[0020] Surface layer 1 is a flame-retardant, antimicrobial polyurethane resin layer, with a silicone hydrophobic layer formed on the side facing away from middle layer 2. This flame-retardant, antimicrobial polyurethane resin layer is formed by coating a polyurethane resin containing flame-retardant and antimicrobial ingredients, forming an artificial leather layer on the surface of the fabric. This not only improves the fabric's wear resistance and durability, but also enhances its texture. The flame-retardant and antimicrobial ingredients also impart excellent flame retardancy and antimicrobial properties to the fabric. The preparation method for the silicone hydrophobic layer includes placing the fabric in a plasma generator and performing a radio-electric discharge treatment. Argon is used as a carrier gas for the silicone, and the argon flow rate is controlled to form a continuous thin film of silicone on the surface of the polyurethane layer, thereby producing hydrophobic PU leather. The silicone is selected from dimethylsilane, trimethylsilane, tetramethylsilane, or hexamethyldisilane, or a combination thereof. The hydrophobic layer imparts a hydrophobic effect to the surface of surface layer 1, enhancing the fabric's resistance to stains.

[0021] The middle layer 2 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are high-strength flame-retardant composite yarns.

[0022] like Figure 2 As shown, the high-strength flame-retardant composite yarn includes a core yarn and a wrapping yarn spirally wound around the core yarn. The core yarn is a twisted yarn formed by twisting two flame-retardant spandex filaments 11 together. The wrapping yarn includes a first composite yarn and a second composite yarn spirally wound around the twisted yarn in a 1:1 ratio. The first composite yarn includes a carbon fiber yarn 12 and a flame-retardant polyester fiber yarn 13 wrapped around the carbon fiber yarn 12. The second composite yarn includes a carbon fiber yarn 12 and a flame-retardant nylon fiber yarn 14 wrapped around the carbon fiber yarn 12. The core yarn is made of flame-retardant spandex and has excellent elasticity and flame retardancy. The wrapping yarn is made of carbon fiber, flame-retardant polyester, and flame-retardant nylon and has excellent flame retardancy, high strength, and conductive and antistatic properties. The high-strength and high-elasticity middle layer 2 gives the automotive seat fabric a higher limit of use and more diverse functions.

[0023] Preferably, the two flame-retardant spandex filaments 11 contained in the twisted yarn have the same fineness.

[0024] The inner layer 3 is formed by interweaving warp yarns and weft yarns, and both the warp yarns and the weft yarns are noise-reducing and flame-retardant composite yarns.

[0025] like Figure 3 As shown, the noise-reducing, flame-retardant composite yarn consists of a core yarn and a wrapping yarn spirally wrapped around the core yarn. The core yarn is a polyester-spandex core-spun yarn, while the wrapping yarn is a basalt polyester core-spun yarn. The polyester-spandex core-spun yarn consists of flame-retardant spandex filaments 11 and a wrapping yarn 13. The basalt polyester core-spun yarn consists of basalt fiber yarn 15 and a wrapping yarn 13. The polyester-spandex core-spun yarn has high elasticity and strength, enhancing the fabric's basic physical properties. The basalt core-spun yarn not only has high strength and elasticity, but also offers sound absorption and noise reduction properties, reducing interior noise to a certain extent.

[0026] The flame-retardant spandex filament 11 is an antibacterial flame-retardant spandex filament. The antibacterial flame-retardant spandex filament is obtained by spinning a flame-retardant masterbatch mixed with spandex chips and then subjecting it to antibacterial impregnation. The flame-retardant polyester fiber yarn 13 is an antibacterial flame-retardant polyester fiber yarn. The antibacterial flame-retardant polyester fiber yarn is obtained by spinning a mixture of antibacterial masterbatch, flame-retardant masterbatch, and polyester chips. The flame-retardant nylon fiber yarn 14 is an antibacterial flame-retardant nylon fiber yarn. The antibacterial flame-retardant nylon fiber yarn is obtained by spinning a mixture of antibacterial masterbatch, flame-retardant masterbatch, and nylon chips. By using these three types of antibacterial yarn, the antibacterial and mildew-resistant properties of the fabric can be enhanced.

[0027] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
