Next, the Leimande laptop backpack manufacturer will give you a detailed introduction to Wulongbu. Let’s get to know it together!

Wulong cloth is a kind of cloth with high appearance value. Its full name is cationic durable polyester. It is a kind of engineering plastic with excellent performance and wide application. It is widely used in fibers, films and plastic products. Chemical name: polybutylene terephthalate (elastic polyester), abbreviation: PBT, which belongs to modified polyester.

Due to the introduction of dimethyl phthalate with a polar group SO3Na in the polyester chip, it can be dyed with cationic dyes at 110 degrees, which greatly improves the color absorption performance of the fiber. Moreover, the crystal is reduced to make the dye molecules easy to penetrate, so that the fibers are easy to be dyed and the color absorption rate is improved. Hygroscopicity is also improved. This kind of fiber not only guarantees cationic easy dyeing, but also increases the micropores of the fiber, improves the dyeing rate, air permeability and hygroscopicity of the fiber, so as to further adapt to the imitation silk of polyester fiber.

The fabric can be made soft, breathable, comfortable, antistatic, and durable under normal temperature and pressure through imitation silk.

Through the cationic modification of multifunctional wool-like fabric, the fabric can be soft to the touch, antistatic, anti-pilling, and can be co-dyed with wool at normal temperature and pressure.

The molecular structure of PET plastic is highly symmetrical, and it has a certain crystal orientation ability, so it has high film-forming and fiber-forming properties. PET plastic has good optical performance and weather resistance, and amorphous PET plastic has good optical transparency. In addition, PET plastic has excellent wear resistance, dimensional stability and electrical insulation.
