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


The color fastness of the webbing is an important evaluation index for printing and dyeing textiles. Different types of dyes used in textiles have different color fastness evaluation indicators. Due to the different types of dyes used, the color fastness evaluation index The difference can reach one and a half. The washing fastness (white cloth staining) of the ribbon dyed cotton fabric is 4-5 for vat dyes, while the vulcanization, Naphto, and reactive dyes are 3 levels. This is because the molecular structure and chemical properties of various webbing dyes are different, and the binding methods and binding forces for different textiles are also different. On the fabric, and some dyes are fixed on the fabric in the form of physical reaction.

Ribbons are classified according to the process, mainly woven belts and knitted belts. Webbing, especially jacquard webbing, is somewhat similar to the fabric labeling process, but the warp yarn of the fabric label is 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, using a small machine. Threading and adjusting the machine can take a long time and is relatively inefficient. But a wide variety of products can be produced, dazzling, and it is not always the same as the cloth label.

The main function of webbing is decorative, and some are functional. Such as the popular mobile phone straps and so on. After the tape is woven, various characters/patterns can also be screen printed, which is generally cheaper than directly weaving the text patterns. 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 anti-sweat requirements, a layer of pvc can also be attached 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 evaluation indicators of its color fastness are not the same. Therefore, it is very important to determine the type of dyes on printed and dyed textiles to assess their color fastness. According to the principle of dyeing and finishing, for different textile raw materials, the types of dyes used are also different. According to the composition of the textile, the type of dyes used can be preliminarily inferred, and then targeted tests are carried out to verify.
