Description

The manufacture method of fiber dyed yarn

Technical field

The present invention relates to the 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 being spun into, and the fabric that look spinning is made into has a kind of dim natural stylistic effects, very popular.Colored fibre in look spinning mostly in the market 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, after concentrated base mercerising, fades serious, color and luster withers secretly, after processing, must carry out complementary color, 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 high temperature dyeing, and dyestuff mostly is s-triazine structure REACTIVE DYES, ability highly basic mercerising, but discharge performance is not good.To sum up, alkaline-resisting can not the pulling out of look spinning, can pull out not alkaline-resisting shortcoming and seriously hinder further developing and applying of look spinning.

Summary of the invention

The object of the present invention is to provide a kind of manufacture method of fiber dyed yarn, its yarn-dyed fabric of producing through this fiber dyed yarn has discharge, makes the photochromic fabric of look spinning mariages have special discharge style.

For achieving the above object, technical scheme of the present invention is the manufacture method of a kind of fiber dyed yarn of design, comprises the steps:

1) dyeing, with dyeing that can discharge, and carry out enzyme processing, the step of soaping; Enzyme treatment conditions are: scouring enzyme consumption 4-6g/L, soda ash consumption 1-2g/L, and temperature is 65 ℃, the time is 40 minutes; Described index of soaping is: soaping agent consumption 8g/L, and 45 minutes time, temperature is 80 ℃; The index of described dyeing liquor is: dye strength is 18%, sodium chloride consumption 50g/L, soda ash consumption 35g/L, and temperature is 65 ℃, the time is 40 minutes;

2) dyeing sliver and other dyeing slivers are spinned, coloured fibre weight accounts for 45% of total weight of fiber;

3) singe, reeling;

4) mercerization finish, temperature is 70 ℃, the processing time is 5 seconds.

Advantage of the present invention and beneficial effect are: a kind of manufacture method of fiber dyed yarn is provided, and its yarn-dyed fabric of producing through this fiber dyed yarn has discharge, make the photochromic fabric of look spinning mariages have special discharge style.
