Abstract
A fabric having unidirectional stretch and recovery force properties suitable for providing the force for dispensing fluid from a container is provided in a fabric construction comprising chain stitches of inelastic yarn, elastomer yarn laid into each course of the fabric providing it with the unidirectional stretch, and substantially inextensible yarn laid lengthwise in said chain stitches to limit the stretch of the fabric in the direction of the chain stitches.
Claims5
A high recovery force warp knit fabric suitable for dispensing application, comprising chain stitches of inelastic yarn, elastomer yarn laid into each course of said chain stitches to provide said fabric with widthwise stretch of at least 200% and recovery force of at least 750 g per cm of fabric length at 100% stretch of said fabric, said elastomer yarn being present in at least 20,000 denier per cm of length of said fabric, and substantially inextensible yarn laid lengthwise in said chain stitches to limit the stretch of said fabric in the direction of said chain stitches upon the stretch of said fabric in the elastomer yarn direction.
