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.
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. And most of them Single and double layer belt Manufacturer Manufacturer The reason why it cannot be used for such a long time is that it is lost in advance rather than other external damage. Therefore, the advice of Xiaobian is not to worry too much about the service life of PP webbing, but to pay attention to how to protect its own Heilongjiang Customized Single and double layer belt Don't lose, don't bring trouble and trouble to yourself.
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.
It may be due to the use of too much thinner, especially the poor compatibility of thinner and ink, which causes color bleeding during PP textile printing. It may be that there is color seeping on the edge of the printed image and text, which is a common phenomenon, so don't worry too much. It can be solved by ordinary methods. It may be caused by the selection of dyes in the ink, or it can be said that it is caused by the improper matching of pigments. We can deal with the problems in this link according to the situation, and pay attention to the details in this link.
