Description
Technical field
The present invention relates to a kind of colouring method of textiles, especially the colouring method of silk fabrics.
Background technology
The dyeing great majority of silk fabrics are to be medium with water, carry out in the aqueous solution of dyestuff.In various degree expanded all can take place in various fibers in water, and dyestuff mainly is that the dispersity with molecule (or ion) spreads in the amorphous region of fiber, by absorption, diffusion, set three phases and the fabric imbue.After dyeing was finished, not being adsorbed on the surface with the dyestuff of fiber generation bonding or reaction can influence COLOR FASTNESS, so also need repeatedly wash or soap etc.Therefore dyeing course is a large amount of water consumptions, power consumption, a large amount of waste discharge, pollutes the process in bad border.
The existing at present research of silk fabrics being carried out the anhydrous few water dyeing of coating; This mainly is to be insoluble granule because coating is most, and it is to disperse to exist with superfine particulate form, and all kinds of fibers are not had affinity substantially, just rely on adhesive at high temperature the bonding force of film forming attached on the fabric.The anhydrous few water dyeing of coating generally is for pad dyeing and blade coating operation, and the advantage of pad dyeing and blade coating all is that dyeing course is easy, the few water of dyeing process.Hard nut to cracks such as but the dyeing of coating pad dyeing, blade coating exists, and the dyeing product feel is coarse, hardboard or COLOR FASTNESS difference.At coating pad dyeing and blade coating dyeing product Boardy Feeling, coarse problem, generally now adopt that the method for soft treatment solves after the sand washing, but the same a large amount of water consumptions of sand washing and soft treatment, produce a large amount of waste water and pollute bad border.
REACTIVE DYES pad dyeing is widely used on COTTON FABRIC in addition, and its principle is dye liquor evenly to be rolled in the fabric under certain pressure with roll, steams by gas then or the method for banking up makes dyestuff combine with fiber.But the dyestuff loose colour that still will will not be bonded to fabric at last by the method for repeatedly washing or soaping is washed off, and this also can produce a large amount of waste water and contaminated environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of improvement of silk dyeing method, this method should be able to overcome the deficiency of above-mentioned background technology, have anhydrous or few water dyeing and exempt to wash, the product COLOR FASTNESS is good, the product feel keeps the peculiar style of silk fabrics characteristics, and water saving, energy-conservation, reduce sewage discharge, reduce cost.
The invention provides following technical scheme:
Wash-free dyeing method for silk, carry out successively according to the following steps:
1), dye liquor preparation: comprise conventional dye well dyeing assistant in the dye liquor, also comprise adhesive; Dye dosage in the dye liquor is 5-50g/l, and binder dosage is 10-100g/l, and dyeing assistant is a small amount of, and all the other are water; After stirring, pours by dye liquor the groove in the padding mangles into;
2), dyeing: the silk fabrics through pre-treatment adopts the mode of rolling of soaking to pad dye liquor on padding mangles, and pick-up rate remains on 70%-85%;
3), preliminary drying: the lining after the dyeing carries out preliminary drying, 70-90 ℃ of preliminary drying temperature, 2～5 minutes preliminary drying time;
4), decatize: in container, lining is carried out decatize; Steam temperature 100-125 ℃, decatize humidity 75-90%, steaming time 10-15 minute;
5), pad softening agent and dry finishing: the lining that decatize is crossed pads softening agent, then oven dry; Softener content in the softening agent is 30-40g/l.
Described adhesive is non-reaction-ing adhesive, comprising SBR emulsion and chitin acetum mixed adhesive, the adhesive of acrylic polymer, polyvinyl acetate class adhesive.
Adopt infrared ray heating preliminary drying before the described preliminary drying operation earlier, 150 ℃-250 ℃ of preliminary drying temperature, preliminary drying time 5-30 second.
Described conventional dyestuff comprises REACTIVE DYES or weak acid dye.
Adopt the present invention that silk fabrics is dyeed, the feel of product can keep the smooth style of the distinctive softness of silk fabrics fully, and the COLOR FASTNESS of product also can reach original requirement; But also save follow-up washing step, and saved a large amount of dyeing waters, reduced energy consumption, also significantly reduced the sewage emissions amount, alleviated influence to environment; The natural production cost is also significantly reduced.
The specific embodiment
Wash-free dyeing method for silk provided by the invention, carry out successively according to the following steps:
1), dye liquor preparation: comprise conventional dyestuff (REACTIVE DYES or weak acid dye) and dyeing assistant in the dye liquor, also comprise adhesive; Dye dosage in the dye liquor is at 5-50g/l, and binder dosage is 10-100g/l, and dyeing assistant determines that as required all the other are water; The dye liquor for preparing is poured into and is prepared to be used to pad silk fabrics in the groove of padding mangles.Because bake after the dyeing or the temperature of decatize higher, all more than 100 ℃, be complementary so the adhesive that adopts should steam temperature with dyestuff gas.
Adhesive generally can be divided into response type and non-response type two big classes.Responding property of reaction-ing adhesive group.Reactive group can and self react with adding crosslinking agent in big molecule of fiber or the mill base, and forming has lightly crosslinked film.Reactive group commonly used is a methylol propionamide etc.Because the introducing of methylol propionamide makes in the big molecule of adhesive and contains the methylol that can react.Methylol can form covalent bonds with crosslinking agent in big molecule of fiber and the mill base, but also self-crosslinking forms netted macromolecular structure.Non-reaction-ing adhesive uses raw material monomer to divide by it mostly.Generally be divided into: the adhesive of SBR emulsion and chitin acetum mixed adhesive, acrylic polymer, polyvinyl acetate class adhesive.The present invention mainly uses the adhesive of the polyacrylate polymers in the non-reaction-ing adhesive, as TYS, Changshu irradiation KG-101, the BASF UDT etc. of De Sida.Non-reaction-ing adhesive promptly melts after temperature acquires a certain degree because big molecule moves easily, and the chance solvent is also dissolved easily.Though reaction-ing adhesive is owing to form crosslinked some performances that changed adhesive, crosslinking degree should be not too high, otherwise fabric softness reduces greatly.Therefore be performances such as raising intensity to non-reaction-ing adhesive, also can suitably add crosslinking agent as required when the allotment mill base, it is lightly crosslinked that non-reaction-ing adhesive is taken place, to change its serviceability.
2, pad dye liquor: pad dye liquor and be and adopt one to soak one and roll and finish this procedure of dyeing; Pick-up rate remains on 70%-85%.
3, preliminary drying: preliminary drying directly adopts the padding mangles baking oven, 70-90 ℃ of preliminary drying temperature, 2～5 minutes time (also can carry out infrared preliminary drying earlier, 150 ℃-250 ℃ of preliminary drying temperature, preliminary drying time 5-30 second);
4, decatize: in container (airtight or open container all can), lining is carried out decatize, steam temperature 100-125 ℃, decatize humidity 75-90%, steaming time 10-15 minute.
5, pad softening agent and dry finishing: the softening agent for preparing (softening agent preparation: softener 30-40g/l) pour in the groove of padding mangles, be used to pad silk fabrics, to improve the feel of product; Afterwards lining is dried processing.
