(2) It has good hydrophilicity, capillary effect and water diffusivity;
(3) Modulus and bending stiffness are half of polyester, so it feels soft;
(4) Good resilience, wrinkle resistance and shape retention;
(5) High limiting oxygen index (L0I 24-29), good self-extinguishing after ignition, low combustion smoke, and good flame retardancy;
(6) It has the ability to prevent ultraviolet rays, and the ultraviolet absorption rate is low;
(7) Low refractive index and good color rendering of dyed products;
(8) Easy to dye, the dyeing temperature is lower than that of polyester.
PLA fiber also has some shortcomings: a. poor abrasion resistance, b. low melting point (about 175°C).
