Background technology
Dyeing and finishing process is high, the higher operation of sewage discharge of textile industry power consumption, is denounced by society all the time.On the traditional understanding, for natural fabric, the acquisition of its color must obtain through printing and dyeing processing again.
Traditional weaving operation is put upside down in the look spinning; Mention painted link before the spinning; After the process reform, can make the yarn that forms by plurality of raw materials blending such as cotton, fiber crops, hair, silk, chemical fibres, its advantage: the one, solved the cylinder difference problem of piece dyeing finishing fully; Look spins as long as color is confirmed, it is unlimited in batches to accomplish; The 2nd, look spins the various different physical characteristic coloration of textile materials problems that solved, various fiber mixing spinnings, and the effect that can produce performance complement, look spins and has given lining unlimited development space.
Because the look spinning is directly to the part stock-dye; The average accounting of coloured fibre is about 35%; Therefore use the ratio of dyestuff and consumption of water also less; " earlier spin after stain " product traditional to the total environment damage ratio reduces more than 50%, meets the requirements of the times of " low-carbon (LC) manufacturing ", is " water-saving and emission-reducing " product in the textile industry.
The prerequisite that the look spinning is able to produce is to obtain colored fibre.CN1073997A " dyeing method for bulk cotton fibres " and CN1266120A " cotton loose-stock dyeing method " disclose a kind of production method of colored cotton fiber respectively.Though utilize the colored cotton fiber to carry out the processing of look spinning; Can reduce pollution than traditional " spinning after stain earlier " to environment; But the technology that discloses in this patent still belongs to traditional colouring method, and bath raio 1:15 in the cotton fiber refining process is warmed up to 100 ℃ of insulations 30 ~ 60 minutes; Bath raio 1:15 ~ 1:20 in the dyeing course is warmed up to 100 ℃ of insulations 60 minutes.Behind refinery practice and dyeing course, also will change water and clean up, process 1 ton of cotton fiber, the water yield that consumes in the whole process will be 50 tons ~ 100 tons, and the consumption of energy is also very big.
The look spinning belongs to trendy product, and the color of textiles is also along with the raising of the consumers living and the level of consumption becomes more and more diversified.For textile enterprise, the production requirement of its product is " small lot, many kinds ".The product lot quantity of some spinning enterprise even little of tens kilograms even several kilograms, and many kinds aspect, change in color is ever-changing.CNS colour system---the CNCS colour system that China Textile Information Center sets up, its CNCS fashion colour atla has just comprised 900 kinds of colors, general lining or have the color kind of dyed yarn manufacturing enterprise all to reach thousands of kinds.
As the production line of the regenerated celulose fibre at the upper reaches, its production line is high surpasses 100,000 tons/year production capacity, low also all at 50,000 tons/year, can not be connected between the requirement of the large-scale production equipment at the upper reaches and downstream " small lot, many kinds ".Examination is calculated with 50,000 tons/year production capacity, and production line production capacity hourly is 7000 kilograms, and look spins the batch of enterprise cotton dyeing and is merely 100 kilograms.Simultaneously, a kind of colored fibre variety production of color is changed next kind after finishing, because mill base need be known the influence of last consignment of time product attached to producing in the pipeline, need put glue and remove contamination in one hour at least.
This just means that regenerated cellulose enterprise can not connect and is less than 10 tons order, even connect order, its production cost also will be higher than conventional variety far away, and its wastage is very huge.Develop colored fibre though why domestic this also be large-scale cellulose fibre manufacturing enterprise, can't move towards market.
Summary of the invention
The objective of the invention is to solve the above-mentioned technical problem that exists in the prior art, the production method of a kind of regenerated celulose fibre and cotton blending coloured spinning is provided.
And utilize coloured regenerated celulose fibre and cotton blending, need not can thoroughly solve the influence of dyeing course to cotton dyeing fully to environment.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
The production method of regenerated celulose fibre of the present invention and cotton blending coloured spinning is carried out blending with more than one and cotton in white, red, yellow, blue, purple, orange, green, the black regenerated celulose fibre and is obtained regenerated celulose fibre and cotton blending coloured spinning.
Regenerated celulose fibre can mix when distributing cotton also and can when drafting, mix with cotton mixing in the inventive method, and the production stage that when distributing cotton, mixes is following:
(1) joins fine color matching: according to the pattern effect of look spinning; According to color theory; According to certain ratio with more than one and cotton fiber in white, red, yellow, blue, purple, orange, green, the black regenerated celulose fibre through pre-treatment; Carry out preliminary mixing and shredding through the equipment of distributing cotton, process lap or directly give down the road carding device, lap or cotton Cong Ding heavily are 350 ~ 450g/m;
(2) combing: after the preliminary mixing of the equipment of distributing cotton, lap or cotton Cong Dingliang deliver to carding equipment, and the further mixing of process carding machine becomes sliver with shredding, boundling, is referred to as the carded sliver, and the carded sliver heavily is 20g/5m surely;
(3) drafting: the carded sliver further carries out mixing in doubling step, and drafting can be two roads or three road draftings, improves the color homogeneity and the bar evenness of sliver through drafting, and the sliver behind drafting is called ripe, and ripe fixed heavily is 20g/m;
(4) spinning: use the spinning of ring spinning machine or revolving cup spinning equipment.
The production stage that mixes during drafting is following:
(1) joins fine color matching: respectively to cotton and in white, red, yellow, blue, purple, orange, green, the black regenerated celulose fibre more than one are carried out preliminary mixing and shredding through the equipment of distributing cotton; Process lap or directly give down the road carding device, lap or cotton Cong Ding heavily are 350 ~ 450g/m;
(2) combing: lap or cotton Cong Dingliang are delivered to carding equipment, and the further mixing of process carding machine becomes sliver with shredding, boundling, is referred to as the carded sliver, and the carded sliver heavily is 20g/5m surely;
(3) drafting: according to the pattern effect of look spinning, according to color theory, according to the monochromatic regenerated celulose fibre carded sliver of certain ratio and the cotton fiber carded sliver, carry out in advance and after carry out redoubling, obtain ripe uniformly of blend of colors, ripe is decided heavily is 20g/m;
(4) spinning: use the spinning of ring spinning machine or revolving cup spinning equipment.
