Problems solved by technology

[0002] 160 s / 2 The long-staple cotton yarn is soft to the touch, has good moisture absorption and breathability, and has excellent wearing performance. Dyeing and finishing production of long-staple cotton skein yarn is extremely difficult
In addition, the yarn is thin and has a large specific surface area, so it can absorb more ultraviolet rays in the sun, and its poor anti-ultraviolet performance also affects 160 s / 2 Industrial production of long-staple cotton yarn

Embodiment 1

[0015] The gauge of long staple cotton yarn is 160 s / 2.

[0016] A production method of ultra-high-count long-staple cotton anti-ultraviolet mercerized yarn, the production process includes singeing → shaking → mercerizing → scouring and bleaching → dyeing and anti-ultraviolet finishing in the same bath → color fixing agent → soft finishing → Drying → rewinding → inspection and packaging; the characteristics are: the color fastness to wet rubbing of the yarn is ≥ 3-4, the color fastness to alkali is ≥ 3-4, and the ultraviolet protection factor UPF is ≥ 35.

[0017] When shaking the yarn, the swing parameters of the main shaft of the shaking machine and the yarn guide rod are adjusted from the conventional 52:44 to 53:39, so that the yarns of each layer are on a rectangular plane, and the inclination is adjusted from a near zero angle to 4.7 degree angle. The net shape of the skeined yarn becomes tighter, and the weight of the skeined yarn of the swinging yarn is reduced to ...

Abstract

The invention discloses a production method of ultra-high-count long-staple cotton anti-ultraviolet mercerized yarn. The production process includes singeing → shaking → mercerizing → scouring and bleaching → dyeing and anti-ultraviolet finishing in the same bath → color fixing agent →softening→drying→rewinding→inspection and packaging; when the yarn is shaken in the present invention, the swing parameters of the main shaft of the yarn shaker and the yarn guide rod are adjusted to make the net shape of the skeined yarn regular and tight, and the skein of the shaken yarn Yarn weight was 120 g / twist. Keep the frame length of the original skein yarn for mercerizing, adjust the spray force of the dyeing machine when dyeing and anti-ultraviolet finishing are treated in the same bath, and solve the key technical problems of easy yarn disorder and broken yarn in the dyeing and finishing of ultra-high-count long-staple cotton yarn. Ultra-high-count long-staple cotton anti-ultraviolet mercerized yarn has color fastness to wet rubbing ≥ grade 3‑4, color fastness to alkali resistance ≥ grade 3‑4, ultraviolet protection factor UPF ≥ 35, and excellent product performance. The production process of the invention has scientific and reasonable design, strong operability and is very friendly to the environment.

Description

technical field [0001] The invention relates to a dyeing and finishing production technology of ultra-high-count long-staple cotton anti-ultraviolet mercerized yarn, especially the three key dyeing and finishing processes of shaking yarn process design, skein yarn mercerizing and jet dyeing and anti-ultraviolet finishing in the same bath production technology. Background technique [0002] 160 s / 2 The long-staple cotton yarn is soft to the touch, has good moisture absorption and breathability, and has excellent wearing performance. Dyeing and finishing production of long-staple cotton skein yarn is extremely difficult. In addition, the yarn is thin and has a large specific surface area, so it can absorb more ultraviolet rays in the sun, and its poor anti-ultraviolet performance also affects 160 s / 2 Industrial production of long-staple cotton yarn. Contents of the invention [0003] The object of the present invention is to provide an ultra-high-count long-staple cott...
