They feed the thinned Alternative into a fiber creation cell, which happens to be a cylindrical machine showcasing a specialised spinneret.
The elongation of the SCY can also be mostly determined by the performance of the spandex core yarn twisting too much, the outer layer of fibre wrapped as well carefully, plus the elastic outcome of your spandex yarn can’t give read more a good efficiency so the elongation decreases.
4. A particular degree of the solid strands are bundled with each other to supply the desired thickness with the assistance of a compressed air machine that twists the fibers jointly.
