The webbing is made of narrow or tubular fabrics of various yarns. With a wide range of fabrics, it is widely used in clothing, industry, agriculture, quartermaster, transportation and other industries. Prior to the 1930s, ribbons were handmade from cotton and hemp. After the founding of the People's Republic of China, the country vigorously developed the textile industry and updated the appearance of the loom. The raw materials used for webbing have gradually developed into polyamide, vinylon, polyester, polypropylene, spandex, viscose, etc., and gradually formed three major categories of weaving, knitting and knitting technologies.

The earliest woven belts were woven by weaving (woven) technology with warp and weft of yarns. After twisting, the yarn is turned into a bobbin (winding head) and the weft yarn is turned into pirn to weave the tape on the loom. In the 1930s, hand-drawn wood and iron-wood looms were used to weave ribbons. In the early 1960s, professional and technical personnel transformed the 1511 loom into a ribbon loom. China has its own ribbon loom, which is still widely used today.

In 1967, the research group of the weaving industry's shuttleless belt weaving belt successfully designed and manufactured a high-speed single shuttle belt weaving machine, which realized the shuttleless belt, shortening the process, miniaturizing the area and increasing labor productivity. This is a pioneering work in the history of Chinese ribbon technology.

In the 1970s, due to the extension of continuous dyeing and ironing machines, the processing of webbing developed from traditional dyeing and weaving techniques to weaving and dyeing, weaving and bleaching, ironing and processing. In the early 1980s, the industry introduced Switzerland, Italy, and the Federal Republic of Germany high-speed non-woven belt machines, ironing machines, packaging machines, warping machines, etc., weaving technology has entered a new stage of development.

Improvements in webbing technology have led to product upgrades. In 1979, the first generation of SD9-9 rubber ingot belt was successfully produced in China, ending its dependence on imports. In 1980, sd-81a, B-type ingot belt was developed, which has the characteristics of softness, lightness, fastness, small elongation, small impact force, short joints and flatness. At the beginning of 1990, it successfully produced a car seat belt that matched the Santana sedan. After more than two years of research and trial production, the product quality has reached qc49-92 and tl-vw470 standards.

Today, although the webbing machinery and equipment are very complex and webbing technology is mature, the development and innovation of webbing machines still need to continue.
