| Polyester is an important species in synthetic fibers. Polyester printed lanyards are commonly used in mobiles phones products. Polyester has a wide application area, extensively used in clothing manufacture and industrial products. The polyester has extremely excellent effigurate performance. Polyester yarn or fabric after generated the amorphous fluffy form or pleats in use by repeated washing, still perishable unchanged.
First of all, printed lanyard has smooth surface, internal molecular are tightly packed, lack of hydrophilic molecular structure, so the moisture regain is small, poor hygroscopic.
And then printed lanyards have good elasticity. Elasticize wool, when elongation of 5% to 6%, almost can completely restored. Crumpling resistance is higher than any other fibers, the fabric does not wrinkle, good dimensional stability. The elastic modulus is 22 ~ 141cN/dtex, and 2 to 3 times higher than the nylon.
Lastly, printed lanyards have high strength. The staple fiber strength is 2.6 ~ 5.7cN/dtex, and high strength fibers is 5.6 ~ 8.0cN/dtex. Due to the low moisture absorption, its wet strength and dry strength are substantially the same. Impact strength is 4 times higher than the nylon, 20 times higher than that of viscose fibers.
