Comfortable. Silk is composed of protein fiber, which has good biocompatibility with human body. In addition, its surface is smooth, and its friction stimulation coefficient to human body is low among all kinds of fibers, only 7.4%. Therefore, it follows the curve of the human body with its supple texture. 2、 Good moisture absorption and desorption. Silk protein fiber is rich in many hydrophilic groups such as amino group (- CHNH), amino group (- NH2), and because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and maintain a certain amount of water. Under normal temperature, it can help the skin to retain a certain amount of moisture, so as not to make the skin too dry; Wearing it in summer can quickly dissipate sweat and heat from human body, making people feel cool.
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 Silk double-layer belt wholesale wholesale 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 Fushun Customized Silk double-layer belt Don't lose, don't bring trouble and trouble to yourself.
What are the characteristics of the edging webbing: moisture retention: because the pure cotton edging webbing is a poor conductor of heat and electricity, the heat conductivity coefficient is extremely low, and because the cotton webbing itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is a bad conductor of heat and electricity, the pure cotton webbing has good moisture retention, and people feel warm when using the pure cotton webbing. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
What backpack webbing means to bags: It is the end of the year again, and a large-scale movement in history is about to begin, which is the Spring Festival travel. In this wave of people returning home, all kinds of bags and backpack webbing have become a beautiful landscape. What's the meaning of backpacking. Bags are widely used in our daily life, especially in the days of Spring Festival travel. What people carry on their backs, what they carry on their hands, and what they hang around their necks, regardless of where they appear, are the knapsack ribbons that are closely related to the human body. It can be said that it is of great significance. Can you imagine the sour and refreshing feeling brought by the sudden rupture of the bag belt when you are carrying a full case of luggage to board the train?
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?
The basic process flow of knitting is: bleaching and dyeing - weft rolling - weaving - off machine cutting - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality. In 1980, SD-81A and B rubber ingot belts were developed, which are soft, light, thin, firm, with small elongation, small impact force, short and flat joints. At the beginning of 1990, the trial production of car seat belts for Santana cars was successful. After more than two years of research and trial production, the product quality reached QC49-92 and TL-VW470 standards.
