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 Cotton ribbon manufactor manufactor 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 Heihe River special Cotton ribbon Don't lose, don't bring trouble and trouble to yourself.
The longitude and latitude are interwoven. [Subject] After twisting, the yarn is warped into a bobbin (pan head), and the weft yarn is shaken into a bobbin, which is woven on the loom. In the 1930s, it was used for hand pulled wood looms and iron wood looms. In the early 1960s, the 1511 loom was converted into a belt loom, which is still widely used. Due to the small width of the belt, the weaving methods are different, ranging from single, double, dozens of pieces, from single layer to double layer. In 1967, the research group of shuttleless weaving belt with workers as the main body in the industry successfully designed and manufactured a high-speed single shuttleless loom by itself, which realized that the weaving belt does not need shuttles, and the process is shortened, the floor area is small, and the labor productivity is improved, which is an innovation in the history of Chinese weaving belt technology.
Silk fabrics have high porosity, so they have good sound absorption, dust absorption and heat resistance. Therefore, in addition to making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. Due to its hygroscopicity, moisture release performance, moisture retention, air absorption and porosity, it can also adjust the indoor temperature and humidity. Silk fiber has small thermal denaturation and is relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600C, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.
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.
