Description
Technical field
The present invention relates to a kind of dacron colouring method, particularly a kind of pad dyeing colouring method of dense dark dacron.
Background technology
Traditional dacron continuous dyeing method has hot melt knot dyeing technology and high temperature steaming decoration method, production efficiency is high, the hot melt continuous knot dyeing method time is short, this technique by dacron by padding dye liquor, preliminary drying, cure fixation and reduction cleaning completes dyeing procedure, color fixing temperature 185 DEG C ~ 220 DEG C, time 3.5 ~ 4min; High temperature steaming decoration method is placed in by fabric in 180 DEG C ~ 190 DEG C high temperature steam boxs, carried out the steaming and color fixing of fabric, time 7 ~ 10min by additional steam.In actual production, the above-mentioned dyeing of usual employing, and when processing the dark product of thick and heavy dacron, often through increase DISPERSE DYES consumption, or interpolation promoter such as certain carrier increases deeply, or silicone finish increases dark mode, or strengthened the mode of external condition by raised temperature etc., promote the raising of the fabric color degree of depth.These methods above, need to add other auxiliary agent usually, and the dark effect of actual increasing and DISPERSE DYES, color and luster kind, processing technology etc. are relevant, have special requirement, and can increase contaminated wastewater and processing cost.And to the color depth of heavily fabric, with through-dyeing, more difficultly to meet the requirements of, and affect COLOR FASTNESS, increase the discharge capacity of waste water and affect environment.A kind of continous mode pad-dry-cure dyeing technique of application number 201310236055.8 dacron fabric, for " steam → roll → dry → roasting " technique, indication is that a leaching one is rolled, and polyester (terylene) fabric passes through (40 ~ 50 DEG C) in advance and evaporates, time longer 15 ~ 30min.Be noted that, (polyester fiber) dacron that, regain poor to hygroscopicity is low, once pad dye extraction, DISPERSE DYES can not be met at tight or that heavily fabric is inner abundant absorption, diffusion, therefore, foregoing invention patent application is not suitable for the continuous prodution processing of dense dark dacron.
Summary of the invention
The object of the present invention is to provide a kind of pad dyeing colouring method of dense dark dacron, in conjunction with traditional continuous melt baking process, is a kind of environmental protection colouring method processing dense dark product.
The step of the technical solution used in the present invention is as follows:
1) dyestuff padding liquid and a pad dyeing is prepared
By DISPERSE DYES 10 ~ 40g/L, penetrating agent JFC 2g/L, Dispersant MF 2g/L, 3% sodium alginate slurry 25 ~ 40g/L, puts into groove, adds water to padding liquid total amount, stir, dacron to be immersed in the padding liquid of groove → by roll roll compacting → immersion dye liquor → roll compacting, be two leachings two and roll, pick-up rate is adjusted to 40 ~ 60%;
2) dacron through padding above cures, and secondary pad dyeing is cured
A, will pad dye liquor dacron send into baking oven at 90 DEG C, dry 1 ~ 1.5min, enter curer at 175 ~ 205 DEG C, fixation 1.5min, go out baking oven and naturally cool;
B, the dacron dyeed entered again groove two soak two and roll former dye liquor, 90 DEG C, preliminary drying 1 ~ 1.5min in step a, at 175 ~ 205 DEG C, cure fixation 1.5min, outlet enters the washing of rear road;
3) dacron will dyeed through secondary, first rinses DYED FABRICS with water, after in 80 DEG C × 3min reduction cleaning, its proportioning is: sodium hydrosulfite 3g/L, caustic soda 3g/L, and all the other are water; Washing, dries; Whole is continuous washing process.
Described dacron is terylene ornamental tape, woven dacron, terylene bundling belt or terylene bunting.
Described DISPERSE DYES is low form dyestuff, middle warm type dyestuff or high temperature modification dyestuff.
The beneficial effect that the present invention has is:
The present invention is different from existing decoration method, and required dye dosage and dyeing time and discharge of wastewater are all better than above-mentioned traditional handicraft, and degree of fixation is high, and color is dark, and through-dyeing is good, and COLOR FASTNESS is excellent.Research shows, the color of secondary exhaust dyeing method increases dark rate, different along with the difference of disperse dyes structure performance, compares with a dyeing, and dye level improves 20% ~ 85%; And reach same target depth of color, comparing with adopting a dyeing of traditional high dye dosage, the utilization rate of dyestuff can be significantly improved.With 15g/L dye strength, 50% liquid carrying rate is example, if its secondary decoration method obtains sample depth, is equivalent to the sample depth of a 50g/L decoration method.Then can save that dyestuff is fabric weight 0.5%, namely produce 1000 kilograms of fabrics, can save or reduce waste water from dyestuff and discharge 5 kilograms.In addition, increase by one washing step after dyeing, can further improve the main COLOR FASTNESS of thick and heavy dacron dyeing product, as WASHING COLOR FASTNESS, the wet fastness 0.5 ~ 1.5 grade of colorfastness to rubbing, particularly friction is (the highest 5 grades, minimum 1 grade), reach product quality requirement.Therefore, this technique can solve the colouring problem of dense dark pad dyeing dacron product, is also a kind of colouring method of environmental protection.
Accompanying drawing explanation
Fig. 1 is process chart of the present invention.
Detailed description of the invention
By following examples, the present invention will be further described.
As shown in Figure 1, dacron of the present invention once pads dye liquor-preliminary drying 90 DEG C × 1 ~ 1.5min-fixation 175 ~ 205 DEG C × 1.5min-and goes out baking oven and naturally cool-and secondary pads former dye liquor-preliminary drying 90 DEG C × 1 ~ 1.5min-fixation 175 ~ 205 DEG C × 1.5min-washing-reduction cleaning, washing, dries.
Padding liquor proportioning:
By DISPERSE DYES 10 ~ 40g/L, penetrating agent JFC 2g/L, Dispersant MF 2g/L, 3% sodium alginate slurry 25 ~ 40g/L, puts into groove, adds water to padding liquid total amount.
Reducing solution proportioning:
Sodium hydrosulfite 3g/L, caustic soda 3g/L, all the other are water.
Wherein penetrating agent JFC is in the short time pads, allow dyestuff rapid osmotic enter polyester fiber inner and must be added penetrant, Dispersant MF is the dispersing aid that must add the peptizaiton of the DISPERSE DYES of water-insoluble particles shape; Be conventional Environmentally-friesurface surface surface-active agent, do not need to add other any medicament again.
Described dacron is: its warp thread, weft yarn are comparatively thick, or yarn twist is higher, or fabric construction is tight, and thicker, light transmission is poor, as various dacron and terylene ribbon.
Described washing process: washing → reduction cleaning → washing → oven dry, once wash before increase, the non-fixing dyes in order to remove DYED FABRICS surface and medicament, alleviate the burden of sequential reduction cleaning simultaneously, further secondary washing, removes in the dyed polyester textiles after being reduced cleaning, the materials such as the oligomer in its polyester fiber, non-set dyestuff and analyte, medicament and auxiliary agent, guarantee the WASHING COLOR FASTNESS of dense dark dacron, colorfastness to rubbing meets the requirements.
For some hard-packed dacrons, owing to there is excessive internal stress, too high color fixing temperature can cause the contraction of fabric, affects the liquid carrying rate of fabric size and secondary pad dyeing.Therefore, in order to not affect the style of dacron, in content of the present invention, for the color fixing temperature of high temperature modification disperse dyed polyester at 205 DEG C or following.
