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 specification 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 treatment → fixing agent fixing → softening finishing → Drying → rewinding → packaging inspection; its characteristics are: color fastness to wet rubbing of yarn ≥ 3-4, color fastness to alkali ≥ 3-4, and UV protection coefficient UPF ≥ 35.

[0017] When spinning, the swing parameters of the spinning machine spindle 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 slope is adjusted from a near zero angle to 4.7 degree angle. The mesh of the hank yarn becomes tighter, and the weight of the hank yarn is reduced to 120g / skein.

Abstract

The invention discloses a production method of ultra-high count long staple cotton anti-ultraviolet mercerized yarn. The production process comprises singeing, reeling, mercerizing, scouring and bleaching, dyeing and anti-ultraviolet finishing in one bath, fixing with a fixing agent, softening finishing, drying, rewinding, inspecting and packaging. During reeling, swinging parameters of a spindleand a yarn guide rod of a reeling machine are adjusted, the net shape of twisted yarn becomes regular and compact, and weight of the twisted yarn of reeling yarn is 120 g/ strand. Frame length betweenoriginal twisted yarns is kept for mercerization, spraying force of a dyeing machine during dyeing and anti-ultraviolet finishing in one bath is adjusted, and key technical problems that ultra-high count long staple cotton yarn is easy to mess and break during production are solved. The ultra-high count long staple cotton anti-ultraviolet mercerized yarn has color fastness to wet friction being higher than or equal to grade 3-4, color fastness to alkalis being higher than or equal to grade 3-4 and UPF (ultraviolet protection factor) being higher than or equal to 35. The product has excellentperformance. The production method has scientific and reasonable production process design and high operability and is quite environmentally friendly.

Description

Technical field [0001] The invention relates to a dyeing and finishing production technology of ultra-high count long-staple cotton anti-ultraviolet mercerizing yarn, in particular to three key dyeing and finishing processes of spinning process design, hank yarn mercerizing and jet dyeing and anti-ultraviolet finishing in the same bath. Production technology. Background technique [0002] 160 s / 2 Long-staple cotton yarn is soft in hand, good in moisture absorption and air permeability, and superior in wearability. However, due to the small number of fibers in the single yarn section and low strength, it is easy to mess and break yarn during the dyeing and finishing of skeined yarn, so it is super high The dyeing and finishing of long-staple cotton hank yarn is extremely difficult. In addition, the yarn is thin and has a large specific surface area. It can absorb more ultraviolet rays in the sun, and its anti-ultraviolet performance is poor, which also affects 160 s / 2 Industria...
