Core Spinning for Elastic Yarn Production
topic
Core-spun yarn machinery feeds an elastane filament under controlled tension through the front roller nip of a ring frame where drafted cotton or polyester fibres are twisted around the elastane core, producing a composite elastic yarn where the sheath fibre provides appearance and skin comfort while the elastane core provides the stretch and recovery for comfort stretch or power stretch fabric applications.
Role
Produces the elastic core-spun yarns that enable stretch and comfort properties in denim, sportswear, intimate apparel, and hosiery fabrics without the full cost or handle of pure elastane fabric, with core elastane draft level determining the stretch percentage and recovery force of the composite yarn that governs the comfort stretch properties of the finished fabric.
