Cooling and Environment: After extrusion, the yarn is cooled to established the spandex layer. This phase is important for keeping the elasticity in the spandex.
The elongation in the SCY is also generally determined by the general performance on the spandex core yarn twisting excessive, the outer layer of fibre wrapped too carefully, and also the elastic influence from the spandex yarn can’t give a fantastic efficiency so which the elongation decreases.
4. A selected quantity of the reliable strands are bundled together to create the specified thickness with the help of a compressed air machine that twists the fibers with each other.
