What is finishing finishing after finishing?
After heat-setting fabric, in addition to improving the dimensional stability, the other performance also has a corresponding change, such as wet rebound performance and pilling performance are improved, feel more stiff;
Generally in a state of tension with the subsequent process of slightly higher temperature processing, that is, heat setting to prevent shrinkage of the fabric deformation, in order to facilitate the post-processing.In addition, the use of heat-setting process combined with other physical or mechanical effects also Can be made elastic yarn (silk), low elastic yarn (silk) and yarn expansion yarn.
Thermoplastic fibers in the textile process will produce internal stress in the dyeing process of wet, hot and external force, prone to fold and deformation, so in the production (especially hot and humid processing such as dyeing or printing)
Heat-setting is the process of making the thermoplastic fiber and its blended or interwoven fabric relatively stable. It is mainly used for the processing of synthetic fibers such as nylon or polyester and its blends after heat shrinkage
The elongation of the thermoplastic fibers decreases with the increase of the heat setting tension, while the strength changes little. If the molding temperature is too high, both of them decrease significantly. The change of the dyeing properties after heat setting varies with the fiber type
