Comparing Properties of the Warp-knitted spacer fabric instead of sponge for automobile seat fabric

Abstract

Abstract The warp-knitted spacer fabric is a new material for automobile seat fabric that can replace sponge in recent years. But its properties of the strength and recovery are very important in laminated car seat fabric. In this paper, the breaking and tearing strength, stress-strain relation was tested and compared. It could be seen that the warp-knitted spacer fabric had excellent performances in strength of breaking and tearing, better air permeability than same thickness sponge. Therefore, it is a good material to replace sponge. Meanwhile, when its thickness was 6mm, the warp-knitted spacer fabric had better ability in the breaking strength, tearing strength, air permeability and the elastic recovery, so it could be used to instead of sponge in lamination car seat fabric for middle layer.
