Abstract

The invention relates to a spinneret plate and a method for producing cross-shaped hollow high-imitation cotton fine-denier polyester yarns. The technical problem to be solved is to design a novel spinneret orifice for producing polyester pre-oriented yarns (POY) with a multi-bladed hollow structure of three blades, a cross (namely four blades), five blades, six blades and the like. The spinneret orifice of the spinneret plate is formed by distributing three, four, five or six equilateral angular spinning seams (1) in an opposite angle mode, wherein inner angles of the angular spinning seams are 180 degrees, 90 degrees, 72 degrees or 60 degrees; the width of each spinning seam (1) is between 0.05 and 0.09 millimeter, and the single-edge length of each spinning seam is between 0.5 and 0.1 millimeter; and the edge interval (2) of each spinning seam and the adjacent spinning seam is between 0.03 and 0.09 millimeter. The cross-shaped hollow high-imitation cotton fine-denier polyester yarns can be obtained by using the spinneret plate with a cross seam and adjusting process parameters of equipment.

Description

[0001] technical field [0002] The invention relates to a differentiated functional polyester chemical fiber for textiles, specifically a highly imitative cotton polyester false-twist textured yarn with a cross shape and a certain hollowness, which has moisture absorption and perspiration, warmth retention and smooth hand feeling and its production method . Background technique [0003] Polyester is a kind of chemical fiber clothing fabric raw material that is widely used in daily life. The biggest advantage of its fabric is that it has good wrinkle resistance and shape retention, and is suitable for outerwear. However, compared with cotton fabrics, polyester fabrics are less hygroscopic, moisturizing, and breathable. They are easy to wear next to the skin and feel stuffy, without the comfort of natural fibers, and have poor hand feeling. With the development of society, the improvement of textile and chemical fiber technology and people's living standards, it is particu...
