High-breathability yarn and manufacturing method thereof

Abstract

The invention relates to high-breathability yarn and a manufacturing method thereof. The fabric related to the yarn has high breathability. The high-breathability yarn is composed of fibers with dumbbell-shaped cross sections. The high-breathability yarn is 75D / 22F dumbbell yarn. The manufacturing method of the high-breathability yarn includes a spinning step and a dyeing step; in the spinning step, yarn fibers with the dumbbell-shaped cross sections are sprayed out by customizing special-shaped spinneret plates; in the dyeing step, reduction cleaning is reinforced, and therefore the phenomenon that fine dye auxiliary particles block pores of the yarn can be prevented. The high-breathability yarn enhances the breathability of the fabric, enhances the moisture absorption effect of the fabric on sweat, improves wear comfort, and greatly lowers clothes cost.

Description

technical field [0001] The invention relates to a polyester air-permeable yarn and a manufacturing method thereof, and the fabric it relates to has strong air permeability. Background technique [0002] The moisture-wicking effect and breathability of the fabric are two characteristics that designers pay attention to. The former is caused by the siphon effect existing in the fabric fibers; the latter depends on the number of voids in the yarn. [0003] see figure 2 , the cross-section of ordinary polyester fiber 30 is a circular cross-section, and the area of ​​the cross-section is small, which is not conducive to the siphon effect. After wearing, at the beginning of the sweating stage, its moisture absorption effect is OK; , the moisture absorption of the fiber is saturated, and the drying speed of the clothing cannot match it, so it cannot effectively wick away sweat, causing the fabric to be close to the body, resulting in a stuffy feeling.

Problems solved by technology

[0003] see figure 2 , the cross-section of ordinary polyester fiber 30 is a circular cross-section, and the area of ​​the cross-section is small, which is not conducive to the siphon effect. After wearing, at the beginning of the sweating stage, its moisture absorption effect is OK; , the moisture absorption of the fiber is saturated, and the drying speed of the clothing cannot match it, so it cannot effectively wick away sweat, resulting in the fabric being close to the body and causing a stuffy feeling.

[0004] see image 3 , COOLMAX yarn is a cross-section fiber 40 yarn, although, relatively, its cross-sectional area increases, so that the moisture absorption and perspiration effect of the fabric is strengthened; but the gaps in the yarn are still not enough, and the air permeability effect is not very good ideal
