Elastane Integration in Warp Knitting
topic
Elastane yarn integration in warp knitting uses separate guide bars feeding elastane under defined pre-stretch levels of 2 to 4 times relaxed length alongside nylon or polyester ground yarn bars, with the elastane tension applying compressive recovery force to the fabric structure after knitting, producing power net and elastic spacer fabrics for swimwear, shapewear, medical compression, and sports compression garments.
Role
Enables production of controlled-compression elastic fabrics for shapewear, swimwear, and medical compression hosiery where the combination of warp knit structure stability and elastane elastic recovery provides defined compression characteristics at different stretch levels, with elastane content, pre-stretch level, and ground fabric structure together determining the pressure-elongation profile of the finished elastic warp knit fabric.
