according to special Clothing ribbon 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. Zhejiang Clothing ribbon 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.

Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
At present, more than 90% of the market is made of cotton polyester thread or polyester cotton thread, but there are few pure cotton threads in the market, and the price is surprisingly high!

Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton. It is easy to wash, heat resistant, alkali resistant, moisturizing, sanitary, wear-resistant, not shrink, not easy to wrinkle, not easy to deform, not easy to stick wool, and so on! The key is that the proportion of cotton and polyester is appropriate! The identification method of pure cotton webbing and polyester cotton webbing is simply to take the cut thread and burn it. If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.
