摘　　要：为降低汽车座椅用织物的制备成本,表层织物利用双层小提花组织设计,采用一定比例的阻燃涤纶与普通涤纶进行交织,兼顾装饰、阻燃、耐磨等性能;中间层使用不同结构的经编间隔织物(WKSF)替代海绵,提高透气性、环保性及缓压性能;里层织物采用涤纶针织物。采用热塑性聚氨酯(TPU)热熔胶网膜黏合剂将3层织物复合层压,研究复合工艺中温度、时间、施胶量等参数对复合材料性能的影响。结果表明:优化复合工艺的温度为120℃、时间为100 s、施胶量为50 g/m^(2);当间隔织物网眼数为45个/(25 cm^(2)),厚度为7.12 mm,间隔丝密度为39.71根/cm^(2)时,中间层织物对复合材料的剥离强力、透气性等性能最佳。通过该复合工艺设计的汽车座椅面料可将阻燃、透气、装饰、绿色环保等功能集于一体,从而适应高档汽车座椅用纺织品的需要。Objective The functional fabrics are one of the important research directions of automotive seat fabrics in recent years.The automotive seat fabrics were made of several materials with different properties to obtain composite functions.In this research,33.3 tex flame-retardant polyester yarn and 33.3 tex ordinary polyester low-elastic yarn were used to produce the automotive seat fabric,using small jacquard stitching double structure,to achieve good decoration effect,and lame resistance.The warp-knitted spacer fabric(WKSP)offers satisfactory air permeability,breaking and tearing strength,and the elastic recovery,so it is a good material to replace sponge.The knitted fabrics are known to have excellent extension to achieve smooth fabric conformation.Method In this work,a simple jacquard fabric was selected as surface fabric(1#).The warp-knitted spacer fabric(WKSF)was used as the middle layer because of its good compression and resilience performance.A knitted fabric was selected as bottom fabric(2#).Then,the 1#,2#and WKSF were glued with a new type of thermoplastic polyurethane(TPU)hot melt adhesive through the self-developed hot pressing bonding machine to perform composite lamination.The laminating process was designed and applied.Under the optimized conditions,peel strength and air permeability were evaluated to explore the influence of WKSF of different structures on lamination.Results Three factors,i.e.the temperature,time and glue amount,were studied and analyzed.The glue amount had a positive impact on the peeling strength,and the compounding time showed a favorable influence on the air permeability of the seat fabric.Meanwhile,TPU hot melt adhesive is a dopted to combine automotive seat fabrics,which could meet the standard or even far higher than the standard evaluation of car seat fabric in air permeability and peeling strength.The orthogonal experiment method was adopted to plan the experiments and the results revealed the optimal composite process parameters,which were composite temperature of 120℃,t
