Study on crease recovery property of warp-knitted jacquard spacer shoe upper material.

Shoe upper materials are often subjected to repeated creasing in use, which affects their shape retention and aesthetic. The crease recovery property of fabrics is an important property that affects its serviceability. Six variants of warp-knitted jacquard spacer fabrics with different jacquard layer structures were selected and the crease recovery angles on six orientation angles were tested for 30 cycles.
