Technical field
The present invention relates to the production methods of a kind of indigo dyeing method and apparatus and high color fastness cowboy's dyed yarn.
Background technique
Indigo cowboy's dyeing is generally two kinds of equipment at present, and one is sizing-dyeing machine, and two be ball warp dyeing machine.Piece-dyeing
Machine the seventies by Changzhou Hong Wei yarn-dyed fabric mill (being now black tree peony group) produce so far, have it is at low cost, pulp is disposably completed,
There is 80% or so tatting cowboy to produce using sizing-dyeing machine at present, but sizing-dyeing machine is easy to produce left, center, right color difference.The U.S.
The introduction of the ball warp dyeing machine of Morrison company production, solves tatting cowboy's side-to-side shading, in many identical works in Changzhou nineties
Factory researches and develops cylinder device processed and produces knitted jean, currently, rope-dyeing is mostly used in knitted jean, also there is cyclic annular dyeing
Machine, the report of sizing-dyeing machine repacking production knitted jean, but measure few.
But existing denim fabric dyefastness is low, cannot cause denim fabric dyefastness with other clothes with wash
Low reason includes following several points:
1, bipseudoindoxyl dye is reduced into leuco compound and upper dye fiber under alkaline condition, then is oxidized to indigo through ventilative oxidation process
Blue, need to repeatedly dye since dyestuff dye-uptake is low can just dye dark color, reoxidize repetition so need to dye oxidation and dye again.?
During air oxidation, the dyestuff and air catalytic oxidation of upper dye fiber cause bronze-colored (it is red to be commonly called as red muscle in dyeing
Block), it is very poor that this substance is sticked to dyefastness on cotton yarn, easily flies upward in weaving process and stains equipment and air, operator
Member deeply hurts.It is difficult to wash out in knitting seam due to bronze-colored dyestuff after washing at cloth, so causing secondary dirt when laundry takes
Dye, with other clothes with washing, when washing, is easy to stain other clothes, and housewife deeply hurts thus.
2, the seventies, the requirement to jeans was the more to wash the more old, and often washing a color will more shallowly, more old more fashion.Cause
Dyefastness problem is not considered substantially when this design equipment.
3, with the changes of the times, at present to the attention of environment, the common people require jeans dyefastness higher and higher.
Denim fabric production is the production method repeatedly polluted, and sewage generation, dyed yarn per ton about 15~20 are had during yarn dyeing
Air and equipment are polluted in the discharge of ton sewage in weaving process, and workshop pollution is big, and one class of direct labor is got off and must be had a bath.
Pollution is also generated in clothing slopwork and water-washing process, enters in city's home in last jeans and same wash of other clothes also can
Pollute other clothes generation sewage can also polluted river channel, so a jeans can generate multiplicating pollution.Printing and dyeing work
Author has spent many brains unsuccessful to improve dyefastness.Specifically: using color fixing agent fixation, concentration control when due to fixation
System, which can not grasp yarn, will cause that fastness is inconsistent, and the clothes of production will cause crosspiece dyeing defect；Denim arrange when be added at
Film property color fixing agent, though fastness take a favorable turn, clothes washing also results in the different situation of clothes cuff, in addition using raising padding machine
Pressure and caustic soda is turned up, the concentration of sodium hydrosulfite is produced effects all very littles.
In traditional technology, cotton fiber cannot achieve continuous dyeing bleaching, after indigo cowboy dyeing at present is all yarn dyeing,
Yarn weaving after dyeing at denim fabric, bleach by the Chinese patent literature cotton fiber continuous dyeing of inventor herein Yang Lixin
Method and apparatus CN105155166A, which is disclosed, a kind of to be arranged cotton fiber for carcass；Then by stitching devices by upper interlayer,
Carcass and lower interlayer are stitched into one, and become the method and apparatus for the suture body that can be continuously transmitted, and realize the continuous of cotton fiber
Dyeing bleaching, refers to production efficiency significantly, reduces costs.But it is how more preferable using cotton fiber continuous dyeing method for bleaching
Ground carries out indigo cowboy's dyeing, and the cotton fiber after indigo cowboy dyeing is spun into the yarn that can be used for weaving denim fabric, according to
It is so the technical issues of this field is not yet fully solved.
