There are two primary methods for coloring, one is to apply it to a wide range of dyeing (conventional dyeing), and the first is to treat it in chemical dye solution. The other method is to use paint to make the paint into tiny insoluble colored particles to stick to the fabric (dyeing of fibrous material stock solution is not included). Acid dyes are mostly suitable for protein fiber, nylon fiber and silk. It is characterized by beautiful color, poor washing degree and excellent dry cleaning degree. It is widely used in natural dead dyeing.
The unused ones from the knitting production line are called. The strength, width, thickness, elongation and stiffness described above are all measured on the knitting production line. The data measured on the knitting production line are called data. The safety belt installed in the car should be worn by the passengers after they get on the car. The use process is an aging process, and its strength will decline. In order to ensure that the safety belt can effectively protect the passengers before the vehicle is scrapped, the strength of the webbing shall be measured after simulating the working conditions. This strength is called the strength after the environmental test. After the environmental test, the strength includes light treatment, low temperature treatment, high temperature treatment, immersion test and wear treatment.
Xiao Bian always believes that any backpack and webbing factory needs to constantly promote safety in production. In addition to conventional production safety and personal safety of employees, fire prevention should be an important part of this safety. Guangdong special Silk double-layer belt The industry is a flammable industry, because a large number of various yarns and finished webbing products stacked in its workshops are flammable, its safety is directly related to human life safety. Therefore, Guangdong Silk double-layer belt manufactor The important thing for enterprises is how to prevent fire. In the past two years, there have been fires in many ribbon factories across the country, which has caused huge property losses to enterprises. The frequent occurrence of fires in the ribbon industry has also sounded a safety alarm for us. The safety of the company is also closely related to the employees. As a member of the company, fire prevention should start from self. Do not smoke in the factory. If you want to smoke, please go to the specified smoking area. Don't throw cigarette butts everywhere, let yourself be a part, and protect our safety together.
Clear drawings within parameters: clear the drawings within the set range of longitude and latitude. Multiple maps to one map: insert multiple maps into one map in the longitudinal direction. One manufacturing to multiple manufacturing: turn in one drawing and disassemble it into multiple pieces in the longitudinal direction. Graph merging: after multiple graphs are handed over and inserted into one (that is, multiple weaving turns to one manufacturing), the whole warp yarn with one upper and lower weave is deleted. Computer jacquard webbing drawing sequence: analyze the weave rule of the jacquard webbing, draw all the "high" parts of the text or pattern in a cycle according to the weave rule that has been analyzed and determined and the actual fabric, and then draw the "high" parts of the background color (color other than text or pattern) in a cycle according to the weave rule. After all the "high" parts are drawn, The "low" part of the pattern and bottom is drawn according to the analyzed organization rule until the drawing is completed.
After the weft tube is formed by the yarn warp cylinder and weft winding, it is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross weave with each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - 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.
It is widely used. Xiaobian will briefly introduce some problems, hoping to help the wholesale friends of selvedge webbing. Main materials: nylon webbing, nylon webbing, cotton webbing, polyester webbing, pp webbing, bamboo fiber and other production processes: textile is a traditional industry in China with a long history. As early as the Tang Dynasty, Chinese textiles have crossed the vast ocean to benefit the world. Today, the textile industry is still a strong industry in China.
