Woven fabrics, knitted fabrics and other types of fabrics must undergo dyeing and finishing processes, such as scouring and bleaching, dyeing or printing, finishing and other processes after they are placed on the loom, in order to complete the above-mentioned finishing content, which means that the fabrics have been bleached, dyed, printed and processed. After processing, in order to improve and improve the quality of the fabric, the textile products that endow the textile with special functions are the textile products that are put on the market. These printing and dyeing processes all belong to the category of fabric finishing.
Fabric finishing can be roughly divided into the following aspects according to its finishing purpose:
1. Make the fabric door width neat and stable in size and shape. This type of finishing includes fixed width, anti-shrinkage and anti-wrinkle and heat setting, which is called setting finishing.
2. Improve the fabric feel. Such as stiff finishing, soft finishing and so on. This type of finishing can use mechanical methods, chemical methods or a combination of the two to treat the fabric to achieve the purpose of finishing.
3. Improve fabric appearance. Such as gloss, whiteness, drapability, etc. There are calendering finishing, whitening finishing and other finishing to improve the surface properties of fabrics.
4. Improvement of other taking performance. Such as flame retardant, water-repellent and hygienic finishing of cotton fabrics; hydrophilic, anti-static, anti-pilling finishing of chemical fiber fabrics, etc.
General fabric finishing
1.Feel finishing
The feel of textiles is related to fiber raw materials, yarn varieties, fabric thickness, weight, organizational structure, and dyeing and finishing processes. As far as fiber materials are concerned, silk fabrics are soft to the touch, hemp fabrics are stiff, and woolen fabrics are bulky, rough and elastic. The hand finishing in this section only refers to stiff finishing and soft finishing.
2. Finishing
Including fixed-width (tenter) and mechanical pre-shrinking, it is used to eliminate the stress and strain accumulated in the fabric in the previous processes, so that the fibers in the fabric can be in a more appropriate natural arrangement, thereby reducing the deformation factor of the fabric . The strain accumulated in the fabric is the main cause of the shrinkage, wrinkle and rough hand of the fabric.
3. Appearance finishing
The main contents of fabric appearance finishing include calendering finishing, electro-optic finishing, embossing finishing and whitening finishing of bleached fabrics. After finishing, the appearance of the fabric can be improved and beautified, such as increased gloss, improved flatness, and the surface is rolled into a concave and convex pattern.
