Is polyester fabric smooth

Update:27 May
Polyester fabrics are smooth fabrics.
It is an important variety of synthetic fibers, also known as polyester fibers, and its major feature is that it has good wrinkle resistance and shape retention. Fabrics woven from ordinary polyester filaments
It has the advantages of good strength, refreshing and crisp, easy to wash and quick drying, but it has the disadvantages of hard hand, poor hand, not soft luster, poor air permeability, and poor hygroscopicity. wash.
Fiber can be divided into short fiber, drawn yarn, textured yarn, decorative yarn, industrial yarn and various differentiated fibers.
Polyester properties include:
1. High strength. The strength of short fiber is 2.6-5.7cN/dtex, and the strength of high-strength fiber is 5.6-8.0cN/dtex. Due to its low hygroscopicity, its wet strength and dry strength basis
The same, the impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber.
2. Good elasticity. Elasticity is close to wool, almost complete recovery when stretched 5% to 6%, wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has a good size
inch stability. The elastic modulus is 22-141cN/dtex, which is 2-3 times that of nylon.
3. Good heat resistance.
