Elastane Core Spinning and Covered Yarn Twisting
topic
Elastane covered yarn production winds synthetic or natural fibre yarn helically around a pre-stretched elastane core under controlled covering tension using ring or TFO twisting, with single cover providing one helical yarn wrap and double cover applying a second wrap in the opposite direction to balance twist liveliness, producing the covered elastane yarns used in hosiery, swimwear elastic, and narrow elastic webbing where the covering protects elastane from UV and chemical degradation.
Role
Produces the textile-covered elastic yarns that combine elastane stretch and recovery with the dyeability, UV resistance, and aesthetic properties of the covering yarn, enabling the production of colour-matched elastic components for hosiery, swimwear, and underwear that bare elastane cannot provide from its limited dyeability and UV sensitivity that covering with dyed nylon or polyester yarn addresses through the mechanical protection and aesthetic enhancement of yarn wrapping.
