Abstract

A nano ZrO2 composite polyester functional fiber contains ZrO2, polybutylene terephthalate, polyethylene terephthalate and a small quantity of auxiliaries, and is manufactured by means of a novel nano ZrO2 powder dispersing and wrapping process and by adjusting a spinning process. The nano ZrO2 composite polyester functional fiber realizes nano-dispersion of nano ZrO2 in a polyester carrier, hydrolysis of composite polyester master batch preparation and degradation of nano composite master batch in polybutylene terephthalate during secondary melting dispersion, and overcomes the shortcomings of the prior art, so that nano ZrO2 powder particles are uniformly distributed and organically compounded in polyester fibers, and mass production of the fiber is realized. A product made of the fiber can efficiently emit biological infrared waves in a long-acting manner, is ultraviolet-resistant, has the health care function of improving human microcirculation and has a sunscreen effect, and a novel fabric market is certainly activated owing to the advantages of functionality, comfort and variety and color diversity of the fiber.

Description

technical field [0001] The invention belongs to the field of new textile materials, in particular to a nanometer ZrO 2 Composite polyester functional fiber and its manufacturing method and application. Background technique [0002] There are a large number of research literature reports at home and abroad on the health care effect and mechanism of infrared radiation on organisms and human bodies and have been widely used. Studies have shown that: 9-11μm band infrared radiation is easily absorbed by human skin, and can be used in the field of warmth preservation and health care; the 10-16μm band infrared radiation frequency is consistent with the natural vibration frequency of the human organic observation group peptide chain, so it can cause resonance in human cells And produce thermal effect, promote the penetration and absorption of drugs, and play a good auxiliary medical effect; in addition, some infrared radiation in specific bands can also stimulate the nervous system...
