Abstract

The invention relates to polyester-nylon composite yarn and a preparation method thereof. The polyester-nylon composite yarn is prepared by conducting measurement, composite spinneret extrusion, cooling, oil applying, stretching, heat shaping and winding on PET flux and PA flux, a composite spinneret is provided with a spinneret hole A and a spinneret hole B different from the spinneret hole A atthe same time, and the microporous length ratio of the spinneret hole A to the spinneret hole B is equal to the product of the equivalent diameter ratio of the spinneret hole A to the spinneret hole B, a coefficient K and the consistency coefficient ratio of a material flowing through the spinneret hole B to a material flowing through the spinneret hole A, wherein the equivalent diameter is the radio of the cross sectional area of one spinneret hole to the cross sectional perimeter of the spinneret hole, and the coefficient K is 0.97-1.03; composite spinneret extrusion means that the PET fluxis extruded from the spinneret hole A, and the PA flux is extruded from the spinneret hole B, or the PET flux is extruded from the spinneret hole B, and the PA flux is extruded from the spinneret holeA. The method is simple and reasonable, the prepared polyester-nylon composite yarn not only has the advantages of a good moisture absorption performance and good dimensional stability at the same time, but also has rich color and lustre, and has an excellent promotion value.

Description

technical field [0001] The invention belongs to the field of fiber preparation, and relates to a polyester-nylon 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 content o...
