Release date:[2024/9/14] Read a total of [80] time

Ribbon weaves warp and weft. The twisted thread is warped into a bobbin (reel), and the weft is rolled into a hook and placed on the loom's webbing. In the 1930s, hand-drawn wood looms and ironwood loom webbing were introduced. In the early 1960s, the 1511 loom was converted into a loom, which is still widely used today. Because the width of the belt is small, the weaving method is different, there are single roots, double roots, dozens of roots, there are single layers, there are double layers.

In 1967, the shuttleless ribbon research group with workers as the main body successfully designed and manufactured a high-speed single shuttleless ribbon weaving machine, which realized the shuttleless ribbon weaving, shortened the process, occupied a small area, and improved labor productivity, which is a pioneering work in the history of Chinese ribbon technology.


In the 1970s, due to the popularity of ribbon continuous dyeing and ironing machines, the processing of ribbon has developed from the traditional first dyeing and weaving to the first dyeing and dyeing, the first weaving and bleaching, and the continuous finishing and ironing. Ribbon technology has entered the ranks of mechanized mass production. In the early 1980s, Switzerland, Italy and the Federal Republic of Germany introduced high-speed shuttle-free belt weaving machines, ironing machines, wrapping machines, warping machines and so on. And ribbon technology has entered a new stage of development.


The advancement of ribbontechnology has brought about the upgrading of products. In 1979, China's first generation of SD9-9 rubber ingot belt was successfully trial-produced, so that rubber ingot belt products ended the history of dependence on imports. 1980 developed SD-81A and B type rubber ingot belt, with soft, thin, strong, small elongation, small impact, short and flat joint characteristics. At the beginning of 1990, the trial production of Santana car safety belt was successful. After more than two years of research and trial production, the product quality has reached QC49-92 and TL-VW470 standards.
