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.
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 second part of our knowledge of printing types. The printing of luggage webbing is a kind of process that I like very much. The first part of what I just said is followed by the second part, which is also very interesting. Let's enjoy it together. Glue printing of luggage webbing. After the emergence and wide application of glue paste in water paste, due to its excellent coverage, it can also print any light color on dark clothes, and has a certain gloss and three-dimensional sense, making ready to wear clothes look more high-end, so it is rapidly popularized, and almost every piece of printed T will use it.
It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, we can directly wrap a unique garment with silk scarves in the hot summer, which is not only beautiful but also comfortable. Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation is proud of its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a large amount of air in these gaps, which prevents the heat emission and makes the silk have good warmth retention.
Selvedge webbing customized Aramid tape manufactor What are the characteristics: moisture retention: because the pure cotton edging ribbon is a poor conductor of heat and electricity, its heat conductivity coefficient is extremely low, and because the cotton ribbon itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is also a bad conductor of heat and electricity, the pure cotton ribbon has good moisture retention customized Aramid tape manufactor Pure cotton ribbon makes people feel warm. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
