What effect does the type of webbing yarn cellulose have on the quality of webbing

The webbing sling color fastness of webbing is an important evaluation index for printing and dyeing textiles, and the evaluation indexes of the color fastness of textiles using different types of dyes are not the same. Due to the different types of dyes used, the difference in color fastness evaluation indexes can reach one and a half levels. The washing fastness of web dyed cotton cloth (white cloth staining) is grade 4-5 for vat dyes, while it is grade 3 for vulcanized, naftor and reactive dyes. This is because the molecular structure and chemical properties of various ribbon dyes are different, and the binding method and binding force for different textiles are also different.

Some ribbon dyes chemically react with textile fiber molecules and bind to the textile by chemical bonds. On the fabric, some dyes are fixed on the textile in a physical reaction.Weaving belts are classified according to the craft, and are mainly woven belts and knitted belts. The webbing, especially the jacquard webbing, is similar to the cloth label process, but the cloth label warp yarns are fixed, and the pattern is expressed by the weft yarn; while the basic weft yarn of the webbing is fixed, and the pattern is expressed by the warp yarn. A small machine is used. It may take a long time to thread the yarn and adjust the machine, and the efficiency is relatively low.


But it can produce a wide range of dazzling products, not always those faces like cloth labels.The main function of the webbing is decorative, and some are functional. Such as popular mobile phone straps. After the tape is woven, various characters/patterns can be screen-printed, which is generally cheaper than knitting the characters directly. The webbing is made of polyester high-strength material, which has the characteristics of high strength, high temperature resistance, high strength and flame resistance.


According to the requirements of anti-sweat, a layer of pvc can be glued to the surface of the webbing, and the pvc and the webbing can be fully bonded together through a special process, which has the effects of wear resistance, corrosion resistance, sweat resistance, and beauty.Therefore, the assessment indicators for its color fastness are different. Therefore, determining the type of dyes on printed and dyed textiles is very important to assess its color fastness. In accordance with the principle of dyeing and finishing, the types of dyes used in webbing are different for different textile materials. According to the composition of textiles, the types of dyes used can be preliminarily inferred, and then targeted tests are carried out to verify.
