Guess the pros and cons. It is difficult to identify the front and back sides of some cases and bags because of their special texture. The following is how the luggage and webbing factory teaches you to identify the front and back of the webbing.

Generally, the patterns on the front are clearer and more beautiful than those on the back. The front pattern of plant and color matching patterned fabrics with striped appearance must be clear and pleasing. This pattern is especially obvious when weaving jacquard belts.
The application of is already very common, and the technology is also new one by one. Let's talk about it briefly from the manufacturer's editor. I hope it can help. It is well known that it has been widely used. Now many bag webbing manufacturers are constantly upgrading their products to make our life more convenient. Knitting can not only weave belts, but also weave ropes. Tubular belt is a kind of braided rope. Rope or rope with a diameter of 1~4 cm is also called rope.

According to the functional data learned by Xiao Bian, the temperature of the lit cigarette is about 700 ℃, and the continuous burning time of a cigarette is about 15 minutes, which is a long time. However, the spontaneous ignition point of common combustibles is very low, such as paper, cotton, linen and knitted fabrics, whose ignition point is mostly 200 ℃ to 300 ℃, so it is easy to cause fire. Turning to the statistics of major and catastrophic fires nationwide, there are many records of fires and casualty accidents caused by smoking after drinking, smoking in bed, littering cigarette butts and other reasons. The typical case is the Great Khingan Mountains forest fire in 1987, which caused a heavy loss of 6.913 billion yuan. It was later discovered that four of the first five fire spots of the fire were caused by human beings, and two of the fire spots were ignited by the cigarette butts of three "smokers".
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.
