The tensile strength after light treatment, the natural light shines on the bag webbing through the window, causing aging and reducing its strength. According to the working conditions, a lighting equipment is designed, which is equipped with representative strong light and is exposed to the light for a specified time. After lighting, pp webbing needs to be subjected to standard temperature and humidity treatment, and then to tensile test to obtain the tensile strength after lighting treatment. After soaking, the tensile strength of the safety belt installed in the car will absorb the moisture in the air, and sometimes it will be soaked by some liquid, so the immersion test is required. At room temperature, fully immerse in distilled water with a small amount of wetting agent for a specified time, and then take out the soaked pp webbing from the water to complete the tensile test within 10 minutes. The tensile strength of soaked pp webbing was obtained.

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.
As an industrial product, it also has its own standard service life, which determines the length of our actual use of webbing. Generally, there are two kinds of situations at the end of use. One is the problem of quality or external damage within the service life, so it can no longer be used. The other is the problem of natural wear and fracture, which is natural damage. It is also inevitable. Today we will talk about the life span in detail. How long is the life span?
quite a lot Shenyang special Silk double-layer belt Manufacturer Printing In mass production of silk screen products, ribbon printing and ribbon printing processing, attention should be paid to printing issues. Screen 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. According to the price of binding ribbon printing and printing Shenyang special Silk double-layer belt The type of substrate is screen. When selecting, it shall be selected and used according to fiber fabric, paper products, glass, ceramics, metal, plastic, wood products, electronic products, etc.
