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.
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.
Direct dyes, suitable for cellulosic fabrics, have poor washing fastness and different light fastness, but the modified direct dyes will improve their washing color. special Aramid tape manufactor Disperse dyes are suitable for viscose, acrylic, nylon, polyester, etc. The fastness to washing is different, polyester is better, and viscose is worse. Azo fuel (Naftol dye) is suitable for cellulosic fabrics. It has beautiful color and is more suitable for beautiful color and luster. Sulphur dye, suitable for Fushun special Aramid tape The color is dim, mainly dark blue, black and brown. The light and water resistance are good, and the chlorine bleaching resistance is poor. Long term storage of the fabric will damage the fiber.
For many printing, attention should be paid to printing when mass producing silk screen products, ribbon printing and ribbon printing. Screen printing is the basis of screen printing, and selecting appropriate screen is an indispensable link. As printing processing and screen printing have a very wide range of applications, there are many factors related to them. When selecting screen, different printing screens should be selected according to the specific situation and printing requirements. Generally, the following different perspectives can be considered when selecting screen. Screen shall be selected according to the type of substrate with binding ribbon printing and printing price. When selecting, it shall be selected and used according to fiber fabric, paper products, glass, ceramics, metal, plastic, wood products, electronic products, etc.
