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.
Flat screen printing. The printing mould is a polyester or nylon screen (pattern) fixed on a square frame with hollow patterns. The pattern on the pattern plate can pass through the color paste, and the mesh without pattern can be sealed with a polymer film. When printing, the pattern is pressed against the fabric, and the color paste is placed on the pattern. The scraper is used to repeatedly scrape and press the color paste to reach the fabric surface through the pattern. Flat screen printing has low production efficiency, but wide adaptability and flexible application, suitable for small batch and multi variety production. Water slurry printing of bag webbing.
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. Heilongjiang special Woven 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, Heilongjiang Woven belt wholesale 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.
The so-called water slurry is a kind of water-based slurry. It doesn't have a strong hand feel and coverage when printed on clothes. It is only suitable for printing on light colored fabrics. The price is relatively flat, and it belongs to a lower grade printing category. But it also has an advantage, because it will not affect the original texture of the fabric, so it is more suitable for large-scale printing patterns. It is characterized by soft handle and bright color~~But there is a big disadvantage of the slurry. The color of the slurry is lighter than the cloth color~~If the cloth color is darker, the slurry can not cover at all.
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.
The printing is in the passenger compartment to enhance the matching and coordination with the color in the cabin. The binding ribbon printing will be dyed into various colors. People always hope that the color dyed will not fade within the specified time. Therefore, the belt has a specific color fastness test. The wrapped webbing belt is exposed to light, and like other substances, it will fade. The wrapped webbing has this characteristic, which is called light color fastness. In this test, the webbing is placed under representative strong light and exposed to the specified time. Then compare the bag webbing with the standard color card to evaluate a fading grade.
