摘　　要：针对再生聚酯面料是否符合汽车内饰要求的问题,采用再生和原生聚酯两种原料,分别设计前梳、中梳均为交替缺垫组织,后梳均为经斜组织的汽车内饰面料,并与海绵复合生产汽车顶棚内饰织物。测试经编织物和复合织物不同方向的拉伸性能,结合纱线、织物表面形貌及结晶度,对比分析两种材料各个方向的力学差异性。结果表明:再生聚酯纤维表面形貌差异不大;复合后再生与原生织物各向平均断裂强力差异率为8.0%,较复合前降低14.5%,且复合后两种织物各向平均断裂伸长差异率仅为0.1%,可知经热熔复合后两种面料力学稳定性得到改善,再生织物力学各向异性十分接近原生织物,表现出优异的力学稳定性,符合汽车内饰模压成形的要求。In order to solve the problem of whether the recycled polyester fabric meets the requirements of automobile interior or not,this paper uses recycled and native polyester to design the front guide bar and middle guide bar with alternating miss-lapping structure,and the back guide bar is the automobile interior fabric with cord lap,which is combined with sponge to produce automobile ceiling interior fabric.By testing the tensile properties of warp knitted fabric and composite fabric in different directions,combined with the surface morphology and crystallinity of yarn and fabric,the mechanical differences in each direction of the two materials are compared and analyzed.The results show that there is little difference in the surface morphology of regenerated polyester fiber.The average difference rate of anisotropic breaking strength between recycled and original fabrics after composition8.0%,which is 14.5%lower than that before composition,and the average difference rate of anisotropic breaking elongation between the two fabrics after composition is only 0.1%.It can be seen that the mechanical stability of the two fabrics is improved after hot-melt composition,and the mechanical anisotropy of recycled fabrics is very close to that of original fabrics,showing excellent mechanical stability,which meets the requirements of automobile interior molding.
