Abstract: the use of plain, twill and satin and heavy flat structure, the use of Flame retardant polyester and polyester DTY with different proportions and intertwined, flame retardant test. Through the comparison of different fabrics of single, double, three layers of fabric air permeability, wear resistance and comfort, and combined with the flame retardant effect and cost factors, the optimum design scheme of automobile seat cover fabric.
            
The best scheme is: Polyester / flame retardant polyester 50 / 50, double layer fabric. As a newly emerging industry in the textile industry, automotive interior fabric is highly targeted and highly difficult to compare with general clothing or household textiles, [1-2]. Blending and interweaving with different characteristics of various chemical fibers can complement each other, improve fabric performance and meet the difficulty of developing automotive interior fabrics.
            
Product design should consider not only the physical properties, comfort and safety of materials, but also the theme and concept of vehicle design, the color and texture of automotive interior system and the individual needs of consumers [3]. At present, the most used textile fabric in automobile seat is polyester, accounting for about 90% [4], and polyester has excellent light stability and thermal stability. This paper adopts flame retardant polyester and polyester Didansi interweave, studied with flame retardant polyester DTY woven fabric in different proportion, different organizations and different fabric layers under the condition of air permeability, wear resistance and comfort, to determine the optimum design scheme of automobile seat cover fabric.
            
The product design 1.1 selects the 300dtex flame retardant polyester yarn produced by Jin Xiaxin Mstar Technology Ltd and 300dtex polyester low elastic yarn. The most common fabric design fabrics of plain, twill, satin weave, 5-7. The fabric will be organized to see 1. 1 on three, double fabric layer and multi-layer fabric also has important significance for the development of cruise car seat fabric products, specifications fabric design parameters of double fabric and three layers of fabric structure and material on the meeting see

Test method: Ignite the fire source (flame height 2 ~ 40mm), and burn the vertical fabric fixed in the U folder at the center of 20mm from the bottom edge of the fabric.
            
In the combustion time, combustion state, fabric testing continued burning time, smoldering time, damage length index. The size of the sample is 30cm x 10cm. The permeability test of fabric used GB / T5453 - 2015 "measurement of textile fabric permeability" to test the permeability of fabric. When the permeability of the back surface of the fabric is different, the small side of the pressure should move down to prevent air leakage. To obtain the accurate permeability of the fabric, the sample can be covered with the airtight cover plate, and the air leakage and the air flow through the fabric are measured separately [Kvc4ue97a
