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.
Xiao Bian always believes that any backpack and webbing factory needs to constantly promote safety in production. In addition to conventional production safety and personal safety of employees, fire prevention should be an important part of this safety. Benxi Customized Cotton ribbon The industry is a flammable industry, because a large number of various yarns and finished webbing products stacked in its workshops are flammable, its safety is directly related to human life safety. Therefore, Benxi Cotton ribbon wholesale The important thing for enterprises is how to prevent fire. In the past two years, there have been fires in many ribbon factories across the country, which has caused huge property losses to enterprises. The frequent occurrence of fires in the ribbon industry has also sounded a safety alarm for us. The safety of the company is also closely related to the employees. As a member of the company, fire prevention should start from self. Do not smoke in the factory. If you want to smoke, please go to the specified smoking area. Don't throw cigarette butts everywhere, let yourself be a part, and protect our safety together.
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.
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.
What type is this? For example: ribbon, plaid belt, jacquard webbing, cotton belt and other products, these should be distinguished first. What is the size? The width and thickness should be understood clearly. What material is this ribbon? Different materials mean different prices. What color is it? How many colors are there? This also needs to be made clear. For example, single color ribbons should be cheaper, while multi color ribbons must be more expensive. Do you need dyeing? Some ribbons are dyed by the customer, and the price of dyeing is different.
Computer drawing process. Many friends are particularly interested in computers. Xiao Bian has briefly introduced the textile technology of computer jacquard belts before, but many people are still interested in how to draw computer jacquard belts. Today, we will introduce its drawing method according to the drawing process of the ribbon. Single color change: change the color of the left or right mouse button in the picture according to the position within the parameter range, and change the color of a connected color block within the parameter range. The color changed depends on whether the left or right mouse button is pressed. Select a rectangular range: click two points in the editing area to form a rectangular range with these two points as the opposite corners, so that you can clear, cut, copy, and organize this rectangular range. Clear out of parameter drawings: Clear the drawings outside the set range of longitude and latitude.
