Abstract

The invention provides a manufacturing method for a colored spun yarn, which comprises the following steps: (1) dyeing: dyeing by using a discharging dye, and during dyeing, performing the steps of enzyme treatment and soaping, wherein the enzyme treatment conditions are as follows: 8-10g/L refining enzyme, 0.1-0.15g/L soda ash, temperature at 40-50 DEG C and time being 30min, and the indexes of the dyeing liquid are as follows: 12% of dye density, 70g/L sodium chloride usage, 25g/L soda ash usage, temperature at 70 DEG C and time being 1 hour; (2) spinning: spinning the dyed slivers obtained in the step (1) with the other dyed slivers, wherein the dyed fiber weight is 5-30% of the total fiber weight; (3) singeing and reeling the slivers obtained in the step (2); and (4) mercerizing, wherein the caustic soda density for the mercerizing treatment is at 30 baume degrees, the temperature is at 60 DEG C and the treating time is 10 seconds. According to the manufacturing method for the colored spun yarn provided by the invention, the variety of the colored spun yarn is enriched and the application scope of the colored spun yarn is widened.

Description

A kind of manufacture method of fiber dyed yarn

Technical field

The present invention relates to field of textiles, particularly, relate to a kind of manufacture method of fiber dyed yarn.

Background technology

Look spinning is generally to mix by two or more different color and luster fibers the yarn that is spun into, and the fabric that the look spinning is made into has a kind of dim natural stylistic effects, and is very popular.Colored fibre in look spinning in the market mostly is cotton bulk fibre and adopts K type or the reactive dyeing of KN type, bright in colour, chromatogram is complete, can form multiple style, but alkaline-resisting mercerising fastness is very poor, serious through fading after the concentrated base mercerising, color and luster withers secretly, must carry out complementary color after processing, strengthen the loss of human and material resources, energy aspect, production efficiency is low; Colored fibre in a kind of look spinning in addition adopts the high temperature dyeing, and dyestuff mostly is the s-triazine structure REACTIVE DYES, ability highly basic mercerising, but the discharge performance is not good.To sum up, alkaline-resisting can not the pulling out of look spinning can be pulled out not alkaline-resisting shortcoming and seriously hindered further developing and using of look spinning.

Summary of the invention

In pin prior art of the present invention, alkaline-resisting can not the pulling out maybe of look spinning can be pulled out not alkaline-resisting shortcoming, and a kind of processing method of fiber dyed yarn is provided.

In order to solve the problems of the technologies described above, the invention provides following technical scheme:

A kind of manufacture method of fiber dyed yarn comprises the following steps,

(1) dyeing, but the dyeing of use discharge; In dyeing, carry out enzyme processing, the step of soaping; The enzyme treatment conditions are: scouring enzyme 8-10g/L, soda ash 0.1-0.15g/L, temperature are that 40～50 ℃, time are 30min; The index of described dyeing liquor is: dye strength is 12%, sodium chloride consumption 70g/L, soda ash consumption 25g/L, temperature are that 70 ℃, time are 1 hour.

(2) the dyeing sliver of step (1) and other sliver that dyes is spinned in spinning; Coloured fibre weight accounts for the 5-30% of total weight of fiber;

(3) to step (2) singe, reeling;

(4) mercerization finish: the caustic soda concentration of mercerization finish is: 30 Baume degrees, temperature are 60 ℃, and the processing time is 10 seconds.

Particularly, described index of soaping is: soaping agent 6 g/L, time 40min, temperature are 50-70 ℃.

The present invention has following beneficial effect:

But changed the common look spinning mercerising of anti-highly basic and the conflicting condition of discharge performance, enlarged the scope of application and the Application Areas of look spinning.Adopt sliver dyeing to replace traditional loose stock dyeing, the pre-treatment time is shortened in 2 hours by 3～5 hours of routine, and the consumption of water, electricity and gas obviously reduces, and has increased substantially operating efficiency, has reduced spinning process difficulty and cycle; Adopt the enzyme treatment process of economic environmental protection to replace traditional high temperature alkali cooking to practice technique, reduced the damage to cotton fiber, increased the spinnability of look spinning, the spinning loss of look spinning obviously reduces, and spinning count gets a promotion; The yarn-dyed fabric of producing through the method has discharge, makes the photochromic fabric of look spinning mariages have special discharge style, and kind is more diversified.
