Description
Technical field
The present invention relates to a kind of cotton yarn section dyeing technique, be specifically related to a kind of from neck yarn to post processing cotton yarn section dyeing technique, belong to textile printing and dyeing field.
Background technology
Section dye refers to catches two or more different colours on hank yarn or fabric.Section dye product is novel unique, and the style that the yarn institute of section dye weaves fabric obtains basic breakthrough, so be deeply subject to the favor of consumers in general.The yarn being applicable to the section of makeing dye has: cotton, polyester-cotton blend, nitrile cotton, short rayon fiber long filament, acrylic fibers, artificial silk, terylene thread, pure wool yarn, nylon wire, polyamide fibre short fiber long filament and various blended yarn, and the dyestuff that may be used for the section of doing dye has: REACTIVE DYES, ACID DYES, DISPERSE DYES, coating etc.
The method of section dye can be robotic segments dye also can be original manual section dye.Direct section can be divided into contaminate for robotic segments dye and indirect section contaminates two kinds.The equipment of robotic segments dye also has a lot, have equipment once most multipotency contaminate six kinds of colors, be dye fixing integration.Dyeing quality is also good; The YD-5-8 eight look reeled yarn section dyeing machine that Ya Caizhengran machinery plant produces is suitable for the color fringe segmental dyeing of various reeled yarn ready-made clothes, and the color that once can contaminate is also many; The DL-8 look vacuum reeled yarn segmental dyeing machine of Wuxi City Yang Jia dyeing and finishing machinery Co., Ltd is applicable to the reeled yarn segmental dyeing of acrylic fibers, wool, blending fiber crops, cotton, terylene, nylon, low-stretch yarn, and dye utilization rate is high, and environmental pollution is little.The people of research section dyeing technique is also more and more, and the mechanical material that section contaminates, auxiliary agent, technique are also all in continuous development.All the time, color-woven fabric is all first by yarn dyeing, and then arranges according to the colored shape of design that dyed yarn carries out weaving.The fabric woven is neatly regular, only have a kind of color from the beginning to the end owing to being every one thread, the just aobvious dullness of the style of the fabric therefore woven is without new meaning, so this fabric style colorful changing of Yarn-dyed fabric be made into through testing, putting into practice, sum up the section yarn dyeing of just designing nearly sixfold color widely is just named as illusion-colour yarn fabric.Its yarn dyeing process feature is the yarn dyeing equipment adopting import special, unique yarn dyeing process, same yarn dyes two to six kinds of different colors, change traditional monochromatic yarn dyeing formula, the Fabric Style be made into obtains basic breakthrough, demonstrates regularity, show third dimension in the planes in irregular, colorful, levels are rich.Especially a yarn six looks be can contaminate at most, design and aesthetic needs farthest met.If weave with the Rapier looms of eight storage latitude drums, just can there are 48 kinds of colors in single broadwise.If coordinate warp thread color, the fabric color that institute weaves is more rich and varied.This fabric adopts textile, polyester-cotton blend or low ratio terylene and silk/cotton blended yarn, therefore has all advantages of such yarn: moisture absorption is ventilative, feel is soft and smooth, cloth cover is smooth, comfortable and easy to wear etc., is the fabric that a kind of comprehensive wearing characteristics is excellent.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, one cotton yarn section dyeing technique is simply and easily provided.
According to technical scheme provided by the invention, a kind of cotton yarn section dyeing technique, step is as follows by weight:
(1) yarn pre-treatment is led:
A, neck yarn dress cylinder: lead out the embryo yarn of respective numbers to deliver from godown according to the quantity that need dye, prepare embryo yarn dress cylinder, check and check quantity, entry according to quantity correspondence spray cylinder cylinder position, often the embryo yarn weight of pipe penetration pipe is 10-12kg;
B, drift yarn: adopt yarn bleaching machine to carry out drift yarn, in yarn bleaching machine cylinder, add auxiliary agent, wherein, bleeding agent is 0.5-1.5g/L, and scutching cotton agent is 1-3g/L, and hydrogen peroxide is 4-6g/L, and being adjusted to temperature is 95-100 DEG C, drift yarn 40-60min; Add glacial acetic acid and regulate pH, be 0.4-0.6g/L to glacial acetic acid content, be cooled to normal temperature, leave standstill 5min, the drift yarn water in cleaning yarn bleaching machine;
C, dehydration: the embryo yarn got after drift yarn enters in Water Extraction Machinery the 4-6min that dewaters, put into charka and prepare section dye after machine to be drained off comes to a complete stop;
(2) section dye dyeing:
A, open single row of tubes: open list according to required color data, and to vacuum section dyeing machine row dyestuff pipe;
B, batching: get formula single, weighing; Heat up water material, water temperature 60-70 DEG C, pours fuel tank into after evenly melting dyestuff; Add in dye tank and melt auxiliary agent; Described auxiliary agent and concentration as follows: thickener 50-80g/L, sodium bicarbonate 15-25g/L, reserve salt 2-3g/L, urea 2-3g/L, bleeding agent 3-5g/L, solvent is clear water;
C, section dye fixation: open vacuum zone dye to the embryo yarn section of the carrying out dye in charka; After section dye, reeled yarn is divided successively on yarn steaming pallet, the folded phenomenon of pressure can not be had; Condensed water is all drained rear unlatching steam and carry out yarn steaming, yarn is put into yarn steaming, in order to avoid the moisture in steam is rushed in yarn; Charka is pushed steam box and close steam box door, start steam box and be warming up to 90-95 DEG C, insulation 20-30min; Open after steam off switch after yarn is received in chamber door cooling and prepare post processing;
(3) post processing:
A, dyed yarn dress yarn: entried gained dyed yarn correspondence spray cylinder cylinder position after the dyeing of section dye, often the embryo yarn weight of pipe penetration pipe is 10-12kg;
B, washing process: the dyed yarn after dress yarn is washed; First add the glacial acetic acid normal temperature washing 4-6min of 0.5-1g/L, wash once with clear water normal temperature; Add the soaping agent of 0.5-1.5g/L, 90-100 DEG C of washing 5min, then wash second time with clear water normal temperature; The softener that mass percentage is 3%-5% is added, washing 10-15min at 30-40 DEG C;
C, go out cylinder dehydration: the dyed yarn 10 after washed is twisted one and even level is put into Water Extraction Machinery carries out processed, go out cylinder after 3-5min and put into charka and prepare to dry to be checked;
(4) pack: put in storage after the dyed yarn after post processing being dried quality inspection packaging, get product yarn.
Described bleeding agent is nonionic penetrant.
Tool of the present invention has the following advantages: the invention provides a kind of technique by machine section dye cotton yarn, its preparation process is simple and convenient, applied widely, by adding the effect of the suitable auxiliary agent section of improve dye dyeing, is all improved color and luster and Liu Se duration.
