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. The reason why most of them cannot be used for such a long time is because they are lost in advance rather than because of other external damage. Therefore, the advice of Xiaobian is not to worry too much about the service life of the PP webbing, but to pay attention to how to protect yourself from loss and trouble.
Zhejiang Customized Single and double layer belt manufactor How much does a yard weigh? This is for accurate quotation. If you calculate the weight of one yard, you can know how much material is used for this yard of webbing. Is it single-sided or double-sided? Some Zhejiang Customized Single and double layer belt There are single side and double side, so this should also be asked clearly. There are pictures for reference. This is to give us a visual judgment Single and double layer belt manufactor , can give the accurate factor of the quotation. How many are there? This is a matter of deciding whether to give customers a discount. If there is a large quantity, there must be a discount. Combine factors such as the wages of the factory, the master and the workers.
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?
Clear drawings within parameters: clear the drawings within the set range of longitude and latitude. Multiple maps to one map: insert multiple maps into one map in the longitudinal direction. One manufacturing to multiple manufacturing: turn in one drawing and disassemble it into multiple pieces in the longitudinal direction. Graph merging: after multiple graphs are handed over and inserted into one (that is, multiple weaving turns to one manufacturing), the whole warp yarn with one upper and lower weave is deleted. Computer jacquard webbing drawing sequence: analyze the weave rule of the jacquard webbing, draw all the "high" parts of the text or pattern in a cycle according to the weave rule that has been analyzed and determined and the actual fabric, and then draw the "high" parts of the background color (color other than text or pattern) in a cycle according to the weave rule. After all the "high" parts are drawn, The "low" part of the pattern and bottom is drawn according to the analyzed organization rule until the drawing is completed.
In the 1970s, due to the promotion of continuous ribbon dyeing and ironing machine, the processing of ribbon has developed from the traditional process of dyeing before weaving to weaving before dyeing, weaving before bleaching, ironing after processing, and the ribbon technology has entered the ranks of mechanized mass production. In the early 1980s, the industry introduced high-speed shuttleless loom, ironing machine, wrapping machine, warping machine, etc. from Switzerland, Italy and the Federal Republic of Germany, and the ribbon technology entered a new stage of development. The progress of webbing technology has brought about the upgrading of products. In 1980, the rubber ingot belt was developed, which has the characteristics of soft, light, thin, firm, small elongation, small impact force, short and flat joints.
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.
