What are the processing methods of polypropylene elastic yarn?

There are many processing methods of polypropylene elastic yarn. Most polypropylene elastic yarns are processed by false twisting method. A twist with the opposite twist direction and the same twist is formed. If the twist direction on the lower thread at the twist point is set as twist, then the twist direction on the upper thread at the twist point is untwisted. When the thread is moved from bottom to top to above the twist point, the resulting The twist will return to zero, and there is no real twist on the thread. Using the thermoplastic properties of chemical fibers, heating and setting are carried out at the lower part of the twisting point, that is, the twisted filaments that have been twisted are removed from the twisting stress in the heat-setting device, and the twisting deformation is fixed. The curled state formed is preserved, which is called curled and fluffy polypropylene elastic yarn. The polypropylene elastic yarn produced by the false twist method has an unbalanced moment and the shape is unstable. In practice, two elastic yarns are often twisted together, and the twisting direction is opposite to that of the original yarn. Polyester low elastic yarn is also processed by false twisting method, which is to further process the twisted textured yarn to make it heat-set again under certain elongation conditions. After processing, the bulkiness of the product is slightly reduced, and the elasticity is considerably improved. .
