Shell fabric with motion followability

Abstract

A stretch fabric has excellent snap back performance. The stretch fabric is a warp knitted fabric formed from hard yams and elastic yams, wherein the included angle (α) between a sinker loop (2) of the elastic yam and the knitting direction of a needle loop is 0-10°, and the included angle (β) between a sinker loop (4) of the hard yam and the knitting direction of a loop is 5-85°. Particularly under high-speed stretching and recovery motion conditions, a wearing pressure increase caused by an elongation stress and a wearing pressure decrease caused by a delayed recovery can be effectively inhibited. Moreover, the wearing comfort can be maintained and muscle vibration can be prevented.
