according to customized Backpack webbing 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. Jilin Backpack webbing 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".
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.
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 are divided into 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 of what is, and give us a more accurate factor of 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.
Silk fabrics have high porosity, so they have good sound absorption, dust absorption and heat resistance. Therefore, in addition to making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. Due to its hygroscopicity, moisture release performance, moisture retention, air absorption and porosity, it can also adjust the indoor temperature and humidity. Silk fiber has small thermal denaturation and is relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600C, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.
