Due to its good performance and wide range of uses, it has developed rapidly and has now become the world's largest chemical fiber. Polyester is mainly short fiber, which is mainly used to blend with cotton, wool viscose fiber, hemp and other chemical fibers to make various clothing textiles.
The main physical and chemical properties of polyester: form The longitudinal surface of polyester is straight and smooth, and the cross-section is round. Polyester is acid-resistant but not alkali-resistant, because the ester groups in polyester macromolecules will be hydrolyzed in lye, but it is also possible to use appropriate lye to imitate the silk. Strong elongation and elasticity Polyester has high strength, high elongation, and good elastic recovery performance. The strength of ordinary polyester is 35.2-52.8cN/tex, and the elongation at break is 30%-40%. According to different processing, polyester has high strength and low elongation, low strength and high elongation and other types.
Due to its high strength, high elongation and good elasticity, polyester has excellent abrasion resistance, second only to nylon. In addition, the initial modulus of polyester is high, so the fabric is crisp and dimensional stability is good. Polyester has only 0.4% moisture regain under normal atmospheric conditions. Therefore, the fabric has the advantages of easy washing and quick drying, and also reflects the defects of poor sweat absorption and air permeability.
