Description
Technical field
The present invention relates to the textile dyeing field, the progressive coloured dyeing of specifically a kind of fabric.
Background technology
At present, the progressive coloured dyeing of top-weight fabrics such as silk broadcloth is mainly carried out on starframe or square frame extension dyeing equipment, the maturation process that is generally adopted is that dyestuff is added method, concrete method is as follows: dye light color earlier, coloured light is taken out 1/3 dye liquor after aiming at, and replenishes a certain amount of dyestuff and dyes middle-grade look, and then take out 1/3 dye liquor, add dyestuff and dye dark color again.Owing to adopted the extension dyeing technique; bath raio is big (being generally 1: 30～50); the dyeing waste of discharging is many and concentration is high; this has not only caused the increase of the energy and raw materials consumption, has also increased the burden of environment, moreover this kind technology having relatively high expectations; the top-weight fabric of plain weave class especially; in lifting process, be easy to generate between the fabric and " take mutually to operation " problem, cause uneven dyeing, the transition that makes depth color is nature.For this reason, the producer that has adopts the method that dye jigger is tilted to install to dye the progressive coloured of plain weave class top-weight fabric, and its concrete grammar is to dye light color earlier, reduces water level then gradually and deepens dye liquor, reaches requirement up to the degree of depth.This method has certain limitation and is equally also having the emission problem of dye liquor aspect the adaptability of fabric variety, especially dyeing later stage, because of color darker, dye liquor concentration is high and fabric area that contact with dye liquor is little, remaining dyestuff is more in the dye liquor, therefore, the dye liquor concentration of discharging is equally also higher.In addition, above-mentioned two kinds of methods once can only be dyed the progressive coloured of a kind of color, dye once more again if will dye the progressive coloured need of two kinds of colors, and can only dye two kinds of colors at most, so be subjected to certain restriction on output and the number of colors.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency that above-mentioned existing technology exists, provide a kind of dyeing waste discharging less, the energy and raw materials consumption is low and the progressive coloured dyeing technique of fabric that once can dye two or more colors.
For this reason, the present invention adopts following technical scheme: the progressive coloured dyeing technique of a kind of fabric, it may further comprise the steps: 1) give fabric coloring, used color applicator comprises a plurality of hydrojet tinters of regulating dyeing liquor concentration, described a plurality of hydrojet tinter is lined up more than one group or two groups, each hydrojet tinter works alone, dyeing liquor concentration to each hydrojet tinter ejection is regulated separately, the dyeing liquor concentration adjustment one-tenth that every group of hydrojet tinter sprayed increases progressively successively in whole width of cloth scope or in certain interval or successively decreases successively, thereby produces progressive coloured on fabric; 2) heating, drying or air dry; 3) vapour steaming colour fixing; 4) washing; 5) dry finishing.If a plurality of hydrojet tinters are lined up one group (or row), can on fabric, produce the progressive coloured of a kind of color; If a plurality of hydrojet tinters are lined up two groups above (comprising two groups), and the color difference of every group of hydrojet tinter ejection, so just can be progressive coloured more than the color of two kinds of generations on the fabric or two kinds.After the fabric coloring drying, overwhelming majority dyestuff is the surface attached to fiber, also not being penetrated into fibrous inside combines with fiber, therefore need to improve COLOR FASTNESS through vapour steaming colour fixing, the equipment of decatize can be garden bucket steam box or continuous steaming machine, during with garden bucket steam box or continuous steaming machine decatize, can be with reference to the process conditions of direct printing, select respectively to evaporate process conditions accordingly according to the kind of fabric, just finished whole dyeing process through washing and arrangement oven dry again after the decatize.
As the further of technique scheme improved and replenish, the present invention takes following technical measures:
Above-mentioned dyeing technique when giving fabric coloring, adopts color applicator move mode or fabric move mode.
Adopting the color applicator move mode is a kind of painting methods of gap, and its concrete method is as follows: fabric is stretched tight puts down on the silk fabric frame that stretches tight of belt track, color applicator in orbit along fabric radially or broadwise move, it is painted simultaneously fabric to be implemented hydrojet.If color applicator is what radially to move to fabric coloring, on fabric, produce progressive coloured be to change in broadwise, adopt this mode can disposablely finish the painted of whole fabric; If color applicator moves to fabric coloring along broadwise, on fabric, produce progressive coloured be radially to change because the length of color applicator has certain limitation, therefore the painted needs of whole fabric repeatedly repeat just can finish.After adopting aforesaid way painted, the drying of fabric can adopt the heating, drying device that moves in orbit to carry out drying or air dry.
Adopting the fabric move mode is a kind of continuous colorize method, it is that color applicator is fixed, color applicator is given fabric coloring when fabric moves, the coloring effect of this mode is identical with the coloring effect of preceding a kind of form of color applicator move mode, can only produce progressive coloured that broadwise changes on fabric.Because fabric is to move continuously, the fabric after therefore painted must be dried at once, to realize continuous painted processing, so this coloring mode can carry out on this kind equipment of hot flue stenter, also can carry out on other similar devices.
Above-mentioned dyeing technique, the dyeing liquor that adjacent hydrojet tinter sprays on fabric is overlapped, and the color that is sprayed on the fabric is formed from shallow to deep or by being deep to progressive effect shallow and that transition is natural, makes progressive effect better.
Another object of the present invention is to provide the color applicator that above-mentioned dyeing technique adopted, a plurality of hydrojet tinters of regulating dyeing liquor concentration, a dilution bucket and dyeing mother vat that at least one provides dyeing liquor for the hydrojet tinter are housed on it, and described hydrojet tinter is made up of the dyeing liquor mixing channel of sealing, the nozzle control valve and the nozzle that are installed in dyeing mother liquid flow rate control valve, diluent stream control valve, the dyeing liquor agitator on mixing channel top and are installed in the mixing channel bottom.The number of dyeing mother vat is corresponding with the kind number of color, if will dye two kinds of colors, then needs two dyeing mother vats.On dyeing mother vat and the dilution bucket overflow launder and circulating pump are housed, liquid during work in the bucket is delivered to overflow launder by circulating pump, because the liquor charging amount of pump is greater than the amount of liquid that flows out, excess liquid will be overflowed overflow launder from the upper edge of overflow launder and be flow back in the bucket again, liquid level in the time of can keeping two barrels of work like this is identical and constant, and is identical with the fluid pressure of guaranteeing the liquid outlet place.A plurality of dyeing mother liquid flow rate control valves and a plurality of diluent stream control valves link to each other with overflow launder drain pipe on the dilution bucket by pipeline and dyeing mother vat respectively.
The inlet of the feed tube on the nozzle control valve is higher than bottom land, mixes up the inlet flow nozzle of the dyeing liquor of concentration by this feed tube in the mixing channel on request, and the dyeing liquor that mixes up concentration of flow nozzle finally sprays application on the fabric after atomizing through compressed air.One dividing plate is arranged in the mixing channel, and it is divided into two parts that communicate up and down with mixing channel, and its effect is to stop the liquid that flows into mixing channel directly to flow to the inlet of feed tube, guarantees to flow into two kinds of liquid of mixing channel through flowing into the inlet of feed tube after stirring again.The bottom of mixing channel has a leakage fluid dram, conveniently the liquid in the mixing channel is discharged.
The present invention compared with prior art has following advantage:
(1) the present invention has removed this procedure of dyeing owing to adopted the dyeing of non-dip-dye, has therefore reduced the dyeing water, thereby has reduced the sewage emissions amount.
(2) existing technology dye is to be affixed on the fabric by the mode that exhausts, and also need discharge some dye liquors in the dyeing course and cause dye loss because of technological requirement, the extension dyeing technique dye loss that particularly bath raio is bigger is more, so the utilization rate of dyestuff is not high; New technology of the present invention is then different, after dyestuff is applied on the fabric, is affixed on the fabric by decatize, and most of dyestuff can be utilized, so the present invention compares with existing technology and can save dyestuff, and this has not only reduced cost, also alleviates the pollution to environment.
(3) steam consumption of the present invention is mainly in the decatize stage, and what its heated mainly is the fabric of doing; And the steam consumption of existing technology is mainly in the dyeing stage, its heating mainly be water, it is many especially to hang dyeing technique bath raio big yield, the consumption of steam is more outstanding, so the present invention can reduce steam consumption, has reduced production cost.
(4) the present invention can realize once dying the progressive coloured of two or more colors by the permutations of hydrojet tinter, reaches the existing technology Color that is beyond one's reach.
In sum, new technology of the present invention has the effect of water saving, energy-conservation reduction raw materials consumption, can alleviate the pollution to environment, realizes cleaning processing production, once can dye the progressive coloured of two or more colors, therefore has very good prospects for application.
The present invention is further illustrated below in conjunction with specification drawings and specific embodiments.
