Abstract

The invention relates to a full-dull polyester and polyester composite yarn and a preparation method thereof. According to the preparation method, dull PET (polyethylene terephthalate) melts and super-bright PET melts are metered, extruded by a composite spinneret plate, cooled, coated with oil and wound to prepare POYs (polyester pre-oriented yarns); the POYs are heated, drawn, falsely twisted, shaped in a heating manner and wound to prepare DTYs (draw texturing yarns) through a yarn guide pipe and a network, namely, the full-dull polyester and polyester composite yarn. An oil agent for oiling contains crown ether, the content of the crown ether is 67.30-85.58wt%, a full-dull polyester and polyester composite yarn extruded by the same composite spinneret plate simultaneously contain dullPET monofilaments dispersed matt agents and super-bright PET monofilaments dispersed matt agents, the matt agents are mixture of unformed titanium dioxide and unformed silicon dioxide or mixture of calcium carbonate and unformed silicon dioxide, and the composite yarn gloss is lower than 20%. The preparation method is simple, the smooth spinning of fibers is achieved in the preparation process, and fabrics prepared by the method are excellent in performance and has great application values.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a full-dull polyester composite yarn and a preparation method thereof. Background technique [0002] With the development of modern textile technology and the continuous improvement of people's living standards, people put forward higher requirements for the output, performance and quality of chemical fibers used in clothing, decorative and industrial textiles. Therefore, in recent years, researchers have devoted themselves to chemical Research and development of new varieties of fibers to meet people's market demand for fibers with high added value. [0003] At present, there is a demand for high-sensitivity and high-functionality textiles in the consumer market. In order to meet these needs, traditional fiber manufacturing must be transformed, and high-function fibers, high-sensitivity fibers, smart fibers, and degradable fibers must be developed. Improve the technological conte...
