What are the factors that affect the Spandex Covered Yarn ?

  1. In the process of spinning,Spandex pre-draft ratio is an important process parameters,it affects Covered yarn,and the elasticity of fabric,and strong influence of Covered Yarn elongation,evenness and creep performance.The predraft ratio of spandex is too small to give full play to the advantages of elastic fabric,which is difficult to draw when drawing too high,and it is easy to cause broken.

  2. Another important process parameter is twist,it affects yarn quality,strong elogation and dry evenness.The increase of twist can increase the binding force between the outsourcing fiber and the spandex fiber,so as to increase the coating strength.The twist is too low,the outsourcing fiber is loose,the coating effected,and the core phenomenon occurs,so the twist should be high when machine is coated.

Spandex Covered Yarn is widely used in the knitting and weaving industries of hosiery,shoe,materials,sweaters,swimming suit,fashion cloths and so on .E-tex enhances your products being better for people who wear them
