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.
customized Aramid ribbon It may be due to the use of too much thinner, especially the poor compatibility of thinner and ink, which causes color bleeding during PP textile printing. It may be that there is color seeping on the edge of the printed image and text, which is a common phenomenon, so don't worry too much. It can be solved by ordinary methods. It may be caused by the selection of dyes in the ink, or it can be said that Harbin customized Aramid ribbon It is caused by improper matching of pigments. We can deal with the problems in this link according to the situation, and pay attention to the details in this link.
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.
Under normal use, the general use time is about three years. After three years, because of natural wear, part of the pp webbing will be corroded and broken. But this is under normal use. If it is not used frequently, similar situations will not occur. The reason why most of them cannot be used for such a long time is because they are lost in advance rather than because of other external damage. Therefore, the advice of Xiaobian is not to worry too much about the service life of the PP webbing, but to pay attention to how to protect yourself from loss and trouble.
