At present, more than 90% of the market is made of cotton polyester thread or polyester cotton thread, but there are few pure cotton threads in the market, and the price is surprisingly high! Polyester cotton yarn just neutralizes the advantages of pure cotton and polyester, depending on the composition of polyester in cotton. Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton. It is easy to wash, heat resistant, alkali resistant, moisturizing, sanitary, wear-resistant, not shrink, not easy to wrinkle, not easy to deform, not easy to stick wool, and so on! The key is that the proportion of cotton and polyester is appropriate! The identification method of pure cotton webbing and polyester cotton webbing is simply to take the cut thread and burn it. If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.

Fujian special Glass cv webbing 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. special Glass cv webbing 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.

Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.

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.
