The elongation of the SCY can be predominantly determined by the functionality of your spandex core yarn twisting excessive, the outer layer of fibre wrapped much too closely, as well as the elastic influence of the spandex yarn can’t give an excellent functionality so which the elongation decreases.
four. A selected amount of the strong strands are bundled collectively to make the specified thickness with the assistance of the compressed air machine that twists the fibers together.
Spandex Extrusion: Spandex is then extruded on to the core yarn. This process is completed in a heated surroundings where by the spandex is inside a molten condition, allowing for it to adhere towards the Main yarn.
in the event the twist is too lower, the outer covering fibre can be free and have an affect on the covering impact, which can induce the core exposure, Hence the twist should be large in mechanical wrapping. Having said that, when the twist is just too significant, The material feels stiff and drapes badly.
