Abstract

The invention relates to the field of polyester filaments, in particularly to a polyester semi-gloss fine-denier hollow POY fiber and a production method thereof. The invention aims at providing the polyester semi-gloss fine-denier hollow POY fiber which is high in profile degree and is good in moisture absorption, dry, comfortable and good in antifouling effect and warm keeping effect after being made into fabric, and further providing the production method of the polyester semi-gloss fine-denier hollow POY fiber. The polyester semi-gloss fine-denier hollow POY fiber is composed of semi-gloss polyester melt, the section of the fiber is of a star-shaped structure of which the middle is hollow, and the length-width ratio of the fiber section is 6:1-8-1; the filament number of the fiber is 0.5-1 detex. By the adoption of the designed polyester semi-gloss fine-denier hollow POY fiber and the production method thereof, the better the woolen-type feeling effect of obtained products is, the higher the fluffiness and warm-keeping property of the fabric which is made of the obtained products are, and therefore the polyester semi-gloss fine-denier hollow POY fiber and the production method thereof greatly improved the competitive capacity of an enterprise.

Description

technical field [0001] The invention relates to the field of polyester filaments, in particular to a polyester semi-gloss fine denier hollow POY fiber and a production method thereof. Background technique [0002] At present, most of the semi-glossy polyester filaments on the market are dominated by round-hole fine denier products. Some large-scale melt direct spinning have successively developed special-shaped products such as flat, hollow, and cross-shaped products, or two-component products developed by using composite boxes. Composite fibers. But such semi-gloss polyester filament product has the following disadvantages: the first, the degree of irregularity of the product is not high; the second, the product has the disadvantages of poor hygroscopicity, dryness, antifouling and warming effect of the fabric obtained after processing. [0003] We urgently need to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to ov...
