|The webbing is made from a variety of yarns. There are many kinds of webbing, which are widely used in various industrial sectors such as clothing, trademark printing, shoe materials, luggage, industry, agriculture, military demand, transportation and so on. In the 1930s, the webbing was produced by hand workshops, and the raw materials were cotton and twine. After the founding of New China, the raw materials for webbing gradually developed into nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major types of processing techniques: weaving, knitting, and knitting. The fabric structure has plain, twill, satin, jacquard, Double layer, multi-layer, tubular and joint organization.|
The cutting of the webbing is usually done in two ways: one is manual cutting and the other is machine shearing. The webbing is widely used. The processing equipment of the webbing also requires high degree of automation and exquisite effect. The traditional webbing shearing is based on the principle of cold shearing and hot shearing. The shearing effect has burrs, loose edges, uneven cuts or appearance. Yellowing and coke. In order to improve this situation, the ultrasonic tape principle can be used to cut the webbing, which can realize full-automatic cutting, ultrasonic sealing, no yellowing and coke, and achieve the desired effect.
