Abstract
The invention discloses a manufacturing method of milk protein fiber or filament or blended yarn dyeing and yarn-colored product, which is characterized by the following: changing coiling density of yarn; controlling heating temperature; adopting segmented contraction in the cylinder yarn dyeing course; adding self-producing milk protein fiber dyeing specific adjuvant; utilizing polyacrylonitile or polyvinyl acetate alcohol as carrier realize active dyeing technology of milk protein fiber; solving the difficulties of flower color, weak color and bad fastening degree problem to produce excellent washing shrinkage and stable size yarn-dyed product through weaving, shrinking and softening and final disposal.
Description
Technical field
The present invention relates to the production method that dyeing of a kind of milk protein fiber or its long filament or its blended yarn and look are knitted product, relate in particular to a kind of milk protein fiber and long filament thereof and also, sth. made by twisting, composite yarn or the dyeing of its short fiber blending yarn and the look production method of knitting product, belong to yarn dyeing and look and knit the woven technical field of production.
Background technology
Milk protein fiber and long filament thereof are high-grade tencel materials, it integrates the advantage of multiple natural protein fibre and chemical fibre, have close skin, support skin, moisture absorption, ventilative, soft, characteristics such as gloss becomes clear, outward appearance is luxurious, and physical and mechanical properties is good; And has a good weaving property; Compatibility with other fiber; Be not afraid of and damage by worms; Performances such as antibiotic, antibacterial, health care are the characteristics of one.But, the immature restriction of milk protein fiber staining technique and hamper its application and popularization in textile industry.
At present, the production of milk protein fiber has two kinds of different methods, all is that the casein depolymerization with amino acid line style in the milk protein becomes after the big molecule of straight chain, and the first is carrier graft copolymerization with the acrylonitrile; It two is to be carrier grafting polycondensation with vinyl acetate alcohol; After making spinning solution, adopt wet spinning technology to carry out the molecule exchange and be solidified into fibre, form the milk protein fiber long filament through drawing-off, oven dry, coiling.Through drawing-off, oven dry, curl, cut off and form the milk protein staple fibre.
Because the spinning solution difference of milk protein fiber, the carrier of polymerization is different with production technology, so the performance of fiber and dyeing way method also are not quite similar.At present traditional milk protein fiber and blended yarn dyeing thereof is not because there is special-purpose dyestuff, and the milk protein fiber of polyacrylonitrile carrier adopts cation dyes, REACTIVE DYES, acid dyeing usually; And the milk protein fiber of polyvinyl alcohol carrier adopts REACTIVE DYES, acid dyeing.But, owing to mostly in producing adopt big capacity, short liquor ratio, the saving energy, reduce the technologies that consume, reduce production cost, no matter adopt which kind of dyeing, all be very easy to occur problems such as look flower, aberration, dye-uptake are low, COLOR FASTNESS difference.Therefore, select wool industry loose stock dyeing commonly used, just seem very unimportant for look flower, aberration, problems such as thermal contraction not homochromy and fiber, perhaps when blending, add be no more than 20% low ratio milk protein fiber again with blending such as natural fabric, regenerated celulose fibre, synthetic fiber or interweave, stay white or do not consider the problems such as dyeability of milk protein fiber, the shortcoming of this production technology and production method is: can not produce at high proportion and pure milk protein fiber product, can not demonstrate fully the premium properties of milk fibre; Have a strong impact on the every COLOR FASTNESS index of product and the vividness of color, the saturation degree of dyeing, the uniformity of color and homochromatism; Feel can not be fully played, and causes all non-constant of flexibility, drapability, elasticity easily.Because milk protein fiber is wet spinning, fibrous inside contains the room of a lot of polar groups, longitudinal groove and cross sections, and fiber self has extremely strong heat-shrinkable and causes yarn or fabric shrink, size instability.Therefore, usually the milk protein fiber of polyacrylonitrile carrier adopts cation dyes, REACTIVE DYES, acid dyeing, when the milk protein fiber of polyvinyl alcohol carrier adopts the conventional method dyeing of REACTIVE DYES, ACID DYES, the difficult colouring of the protein part of milk fibre, very easily produce dye saturating, to dye irregular, aberration, look flower, feel poor, problems such as cloth cover sclerosis.So, no matter which kind of milk protein fiber and which kind of dyeing, except selecting the rational technological process of production for use, occur that look flower, aberration, COLOR FASTNESS are poor, the size instability is its dyeing and hinder milk protein fiber and use insoluble key problem in technology in textile industry.
Summary of the invention
The purpose of this invention is to provide that a kind of dye stability is good, favorable reproducibility, even dyeing, COLOR FASTNESS height, feel good springiness, gloss is bright, loss and waste is little, technology is simple, easy to operate, consistent, dyeing back is realized easily producing and is promoted and the deep processing of product, improves that the high blending of milk protein fiber is when pure to be spun or its blended yarn dyes and look is knitted production method.
For realizing above purpose, technical scheme of the present invention provides the method that a kind of milk protein fiber or the dyeing of its blended yarn and look are knitted production, it is characterized in that, milk long filament or its milk staple fibre or its blended yarn, loose type coning, milk protein fiber special dyeing auxiliary agent, reactive dyeing.Its method is:
The first step: milk protein fiber or its long filament Bao Xin, coating, plying double twisting or its blended yarn loosely are wound on the smooth paper tube, become the long filament milk protein fiber of loose type coning or the cheese of its blended yarn, rolling density is 0.26g/cm
3-0.35g/cm
3, convoluting speed 8m/s-20m/s;
Second step: the mesh plastic tube that will dye cheese is squeezed in the paper tube, and the paper tube when withdrawing from loose type coning makes the bigger gap of generation between yarn and the plastic tube; If can reach above-mentioned rolling density during loose type coning, can change paper tube into plastic tube in the first step, directly finish the metal process and ignore second the step;
The 3rd step: with the synthetic high polymer film of reticulated or porous, long filament milk fibre or its blended yarn of loose type coning wrapped up, fluff when pine, slippage and dyeing very much to prevent yarn;
The 4th step: the cheese that will have plastic tube is put into yarn expansion, contraction, calibrator, carrying out temperature is 40 ℃-60 ℃, time is 10-20 minute damp and hot typing, be warming up to 75 ℃-85 ℃ again after making yarn obtain shrinking for the first time, time is 10-20 minute, makes yarn obtain shrinking for the second time, when yarn pack tightly netted mould pipe after, adorn cage, prepare dyeing.
The 5th step: dyeing
