But another disadvantage is that it is moisture permeable and not waterproof. If you wear a swimsuit made of this kind of fabric underwater, the water flow will definitely soak the whole swimsuit and increase the load. In addition, the water flow will fill between the swimsuit and the body, increasing the resistance of advancement; As outdoor sports clothing, rock climbing clothing must be able to adapt to the harsh weather conditions outside
According to various data, there are few professional rock climbing clot

Abstract

The invention discloses a dual-direction high-elastic warp-knitted fabric and a production method thereof. The dual-direction high-elastic warp-knitted fabric is formed by interweaving polyurethane yarns and other non-elastic yarns, and when in weaving, guide bar for guiding the coiling of the polyurethane yarns transversely moves for 2 to 4 stitch lengths and is opposite to the moving direction of other guide bar yarn inlays. The dual-direction high-elastic warp-knitted fabric has balanced elasticity proportion in the longitudinal and the transverse directions and has excellent elasticity recoverability. Swimsuits made of the warp-knitted fabric have strong guide effect and excellent hydrophobic effect. Moreover, the dual-direction high-elastic warp-knitted fabric has low running water resistance and is particularly suitable for producing close-fitted sportswear with high elasticity requirements such as swimsuit, rock climbing clothing, exercise clothing and the like.

Description

technical field [0001] The invention relates to a two-way high elastic warp knitted fabric and a production method thereof. Background technique [0002] Elastic fabrics (knitted fabrics) that are stretchable both longitudinally and transversely are called two-way elastic fabrics (knitted fabrics). Two-way stretch warp knitted fabrics are warp knitted fabrics that contain elastic yarns. The leading two-way elastic warp knitted fabrics on the market are generally interwoven with elastic yarns and non-elastic yarns, but the elastic yarns are mostly formed into loops with a transverse movement of 1 gauge. Although this type of elastic knitted fabric also has two-way elasticity, there is a large difference between the longitudinal elasticity and the transverse elasticity, and often the longitudinal elastic elongation remains, and the transverse elastic elongation is too small, resulting in uneven distribution of longitudinal and transverse elastic ratios, which restricts the la...
