Abstract:

This paper mainly focuses on the important property of car seat fabric in practical use.  Twelve kinds of pattern samples selected and divided in two groups (jacquard baisc texture and facquard pattern texture), according to the different characteristics of their pattern, and use four kinds of typical seam stitch on knitting fabric to complete sample processing first. Then we adopt the strip method to conduct the tensile fracture test about seam strength and tensile rupture of the primary fabrics, both warp and weft directions respectively. By processing and analysis the data obtained from the test, we find the best seam stitch which is able to maximize seam strength of warp knitting jacquard spacer fabric, and summarize the influence of different pattern structure on seam strength both warp and weft was summarized, and it is expecting to provide guidance for the pattern design of warp knitting jacquard spacer fabric used on automobile seats.

Key words: car seat, warp knitting, jacquard spacer, seam strength, seam stitch
