The basic process flow of knitting is: bleaching and dyeing - weft rolling - weaving - off machine cutting - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality. In 1980, SD-81A and B rubber ingot belts were developed, which are soft, light, thin, firm, with small elongation, small impact force, short and flat joints. At the beginning of 1990, the trial production of car seat belts for Santana cars was successful. After more than two years of research and trial production, the product quality reached QC49-92 and TL-VW470 standards.
