Characteristics of Shijiazhuang Jiadingsheng Decoration Tianjin Bangmei Advertising Decoration Polyester
The strength of short fiber is 2.6 ~ 5.7 cn/dtex, and the strength of high strength fiber is 5.6 ~ 8.0 cn/dtex.
Because of its low hygroscopicity, its wet strength is basically the same as its dry strength.
The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber.
2. Good elasticity.
Elasticity is close to wool, and it can be almost completely restored by stretching 5% ~ 6%.
The crease resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability.
Polyester fabric has high strength and strong elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing.
3. Heat-resistant polyester is made by melt spinning, and the formed fiber can be heated and melted again, which belongs to thermoplastic fiber.
Polyester fiber has higher melting point, but lower specific heat capacity and thermal conductivity, so polyester fiber has higher heat resistance and heat insulation.
This is the best fiber.
4. Polyester has smooth surface and tight internal molecular arrangement.
Polyester is the fabric with the best heat resistance among fiber fabrics, which is thermoplastic and can be made into pleated skirts with lasting pleats.
At the same time, the polyester fabric has poor melting resistance, and it is easy to form holes when encountering soot and Mars.
Therefore, contact with cigarette butts and sparks should be avoided when wearing.
5, good wear resistance.
Wear resistance is second only to nylon with the best wear resistance, and better than other natural fibers and fibers.
6. Good light resistance.
Light resistance is second only to acrylic fiber.
The light fastness of polyester fabric is better than acrylic fiber, and its light fastness is better than natural fiber fabric.
Especially behind the glass, the sun resistance is very good, almost equal to acrylic fiber.
