Threads of different thicknesses are passed through the machine to be made into fabric. Fabrics made of threads with different materials and thicknesses through different arrangement rules will also have greater differences in functionality, and they will be made into functional fabrics with different functions.
The function of the fabric determines the characteristics of the backpack, whether it is waterproof, scratch-resistant, wear-resistant, or ultra-light, ultra-thin and tough. At the same time, the quality of the fabric directly determines the quality and price of the backpack.
At present, the most commonly used backpack is Polyamide, which is a general term for thermoplastic resins containing repeating amide groups—[NHCO]—on the main chain of the molecule. Including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application, and its name is determined by the specific carbon number of the synthetic monomer.
The backpack made of PA fabric is particularly easy to take care of. It can be machine washed, and the drying time is three times faster than that of cotton. It is not easy to deform and has the significant anti-wrinkle ability. It has excellent resilience, is particularly light, has strong water absorption, and is flame retardant. It can also be added through the coating, dip dyeing and other processes.
Compared with the deformation resistance of nylon, the biggest feature of Amylon is just the opposite. It is highly elastic and can be elongated 6-7 times, and it can be restored as the tension disappears. Spandex is generally not used alone but is incorporated into the fabric in a small amount. This fiber has both rubber properties and fiber properties.
The advantage of polyester is its high strength. Its strength is 4 times higher than that of nylon. It has good elasticity and has an expansion capacity of 5% to 6%. It has good heat resistance and insulation properties and can be thermoplastic, but it is easily burned when exposed to open flames. The surface is smooth, has good plasticity, and is also wear-resistant, light-resistant and corrosion-resistant. It's just that it has poor water absorption and is prone to static electricity.
No matter what style and size you choose, the leather bag will definitely bring you durability, or in other words, long service life. It is also strong enough to withstand all rough operations and will not easily leave dirt.
