Manufacturing method of moisture-conducting and temperature-conducting wicking polyester fibers

Abstract

The invention relates to a manufacturing method of moisture-conducting and temperature-conducting wicking polyester fibers. The manufacturing method comprises the following steps that multi-arc cross-shaped spinneret orifices are adopted; wherein the multi-arc cross shape comprises four leaves, namely a leaf I, a leaf II, a leaf III and a leaf IV; the leaf I is defined by two line segments and a major arc; the two line segments are parallel to each other, the two ends of each line segment are flush, one end of each line segment is an m end, the other end of each line segment is an n end, and the m ends of the two line segments are connected through the major arc; a straight line, which passes through the circle center of the circle corresponding to the major arc and is simultaneously arranged at equal intervals with the two line segments, is taken as a line L, wherein one point, which is positioned outside the leaf I and is close to the n end, on the line L is a point O; the leaf II, the leaf III and the leaf IV are correspondingly formed by rotating the leaf I around the point O by 90 degrees, 180 degrees and 270 degrees respectively; and the technological process comprises a winding procedure. A comb-shaped filament separator is arranged in a winding machine, and the comb-shaped filament separator porcelain piece is shaped like a formula as shown in the specification. The problems that in the prior art, a large number of broken filaments and filament burrs are generated in the spinning process, and tows are prone to jumping out when passing through a comb-shaped filamentseparator porcelain piece are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of functional polyester fibers, and relates to a method for manufacturing moisture-conducting and temperature-conducting wicking polyester fibers. Background technique [0002] In the chemical fiber industry, the rear products of "ten" shaped special-shaped fibers have very good moisture absorption and perspiration performance. The moisture absorption and perspiration is to use physical methods to make the surface of polyester fibers produce fine grooves with capillary effect, and the sweat is absorbed and diffused by wicking. , transmission and other functions, quickly move to the surface of the fabric and evaporate quickly, so as to keep the dry feeling of human skin. However, the production process of the "ten" shaped special-shaped fiber on the market basically adopts the ordinary "ten" shaped spinneret hole spinneret, which will bring many adverse effects to the subsequent processing. Spinning with suc...

AI Technical Summary

Problems solved by technology

The existing comb-shaped yarn separator porcelain is a "U"-shaped porcelain piece, which is characterized by a simple structure and easy filament separation. The disadvantage is that the structure is relatively weak and easy to damage, and the restraint of the filament bundles is poor, and it is easy to drift during spinning. Wire jumping occurs when the wire and winding are switched, which leads to misaligned wires and end breaks, etc.
