Abstract

The invention discloses a polyester fiber. The fiber contains inorganic particles which are 2.5-24.0 wt% of the fiber, the generation quantity of free radicals of the polyester fiber after irradiationwith light with the wavelength of 300-400 nm is 1.0*10<15> / cm<2> or below, and the fiber has excellent light resistance, transmitting prevention property, ultraviolet resistance and heat shielding property. A fabric prepared from the fiber has good light resistance, transmitting prevention property, ultraviolet resistance and heat shielding property.

Description

technical field [0001] The invention relates to a polyester fiber and a fabric using the fiber, in particular to a composite polyester fiber containing high content of inorganic particles, less free radical generation, good light resistance, high anti-permeability and anti-ultraviolet. Background technique [0002] Visual shading is an important performance of textiles. In the field of clothing, it is related to the most basic function of covering the body; in the field of decoration and military, it involves special visual requirements such as one-way perspective and camouflage. In addition, with the worldwide use of Freon in large quantities and the increasing environmental pollution, the ozone layer in the atmosphere has been severely damaged. Long-term exposure to ultraviolet radiation will reduce the lifespan of organic molecules and reduce the immune function of the human body. It will not only damage the skin and cause dermatitis, erythema, freckles and skin cancer, b...
