Description

A kind of coating mordanting technique of half shading window decorations
Technical field
The present invention relates to the preparation technology of window decorations, particularly relate to the coating mordanting technique of a kind of half shading window decorations.
Background technology
Beautiful attract eyeball very much although product color that modern textiles coating dyeing and finishing is out is gorgeous, but the cost that the gorgeous beautiful behind of this color is paid is water pollution;Dyeing waste water is to process the waste water that cotton, fiber crops, chemical fibre and blending product thereof are main printing and dyeing mill's discharge;The textile waste water of about 70-80% is from printing and dyeing.The dyeing waste water water yield is relatively big, and 1 ton of textile water consumption of every dyeing and printing process 100~200 tons, wherein 80~90% become waste water.Textile printing and dyeing wastewater has the features such as the water yield is big, organic pollution content is high, alkalescence is big, change of water quality is big, belongs to one of intractable industrial wastewater, containing dyestuff, slurry, auxiliary agent, oil preparation, soda acid, fiber impurity, sand class material, inorganic salt etc. in waste water.It is to reduce sewage to produce that printing and dyeing arrange industry a great problem.
CN102433645B (2013-6-19) discloses the production technology of flame-retarded sun-shading curtain cloth, but the waste water that this invention produces is more, and can only prepare full window shade cloth.
Summary of the invention
It is an object of the invention to provide a kind of printing and dyeing and coating are simultaneously completed, coating mordanting technique of minimizing sewage generation half shading window decorations.
The above-mentioned technical purpose of the present invention has the technical scheme that
A kind of coating mordanting technique of half shading window decorations, it comprises the following steps successively:
(1) prepared by grey cloth;
(2) aqueous mordanting slurry modulation: preparation environment-friendly type flexible glue 25-45 part, stiffening glue 13-18 part, water 35-47 part, high-efficient penetrant 1-5 part, defoamer 0.01-0.2 part, colouring stabilizer 0.2-1.5 part, UV absorbent 0.5-1.5 part, dyestuff 8-10 part by weight;
(3) mordanting and coating: described grey cloth is put in described aqueous mordanting slurry and pad, coat through pressure roller pressure rolling under air pressure 0.3-0.4Mpa, speed 10-15m/min;
(4) smooth process: by the grey cloth pin hole slurry Adsorption after mordanting and coating;
(5) Final finishing: cold wind cooling after drying at 165-180 DEG C.
Mordanting of the present invention and coating paste use same aqueous mordanting slurry, so that printing and dyeing mordanting and coating complete simultaneously, decrease waste water and produce;Aqueous mordanting the most of the present invention slurry safety and environmental protection, can realize environmental protection and produce;
The aqueous mordanting slurry made by special component and proportioning can realize printing and dyeing and half shading coating simultaneously, and half shading coating is effective;Simultaneously by the grey cloth pin hole slurry after mordanting and coating through slurry adsorption plane panel assembly Adsorption, while the overall appearance improving grey cloth and flatness, again because baking and banking up with earth of Final finishing can strengthen degree of staining for twice with cold wind cooling, thus finally acquisition color fastness is good, half shading window decorations especially half window shade of half good shading effect.
As preferably, described stiffening glue is polystyrene, acrylic acid or vinyl acetate and one or more in the anionic emulsion of acrylic ester copolymer;Described high-efficient penetrant is disecoctylmaleate sodium sulfonate;Defoamer is polysiloxane defoaming agent;Colouring stabilizer is that liquid barium zinc compound stabilizer, liquid barium cadmium compound appraise and decide agent, liquid barium cadmium zinc is compound appraises and decides agent or 4-benzoyloxy-2, one or more in 2,6,6-tetramethyl piperidines;UV absorbent is oxybenzoic acid phenyl ester, 2-(2-hydroxy-5-methyl base phenyl) one or more in BTA or ESCALOL 567.
As preferably, the preparation of described grey cloth includes turning over cloth, and weft yarn opens sanction, margin to seam, singes and be prepared by flower pattern hollow out organizational structure;Sanction opened by described weft yarn is to be cut apart with a knife or scissors by weft yarn by fabric;Described margin to seam is that margin to seam between board, between fabric is carried out the parallel margin to seam of weft yarn.
As preferably, described dyestuff includes reactive dye and reducing dye, described reactive dye are the Levafix EA of De Sida company, at least one in Procion H-EXL, Cibacron Light type reactive dye, and reducing dye is Fructus Canarii albi T, at least one in blue ARN, red R, black ES-SE, blue RSN, blue CLF, purple 2R.
The window decorations color using this dyestuff to prepare is soft, does not fades.
As preferably, described environment-friendly type flexible glue is made up of the raw material of following parts by weight:
Polyurethane 70-95 part, phthalic anhydride 25-35 part, triethylene glycol 10-12 part, 1,3-propanedicarboxylic acid 15-18 part, butantriol 8-10 part, Zinc Oxide 5-7 part, magnesium oxide 3-5 part, neoprene 15-25 part, softening oil 2-3 part, dimethyl carbonate 15-20 part, ethylbenzene 20-30 part, fire retardant 1-3 part;
Described fire retardant is counted composed of the following components by weight: ammonium low polyphosphate 20~50 parts, ammonium phosphate 10~25 parts, ammonium pyrophosphate 6~12 parts, ammonium sulfate 5~20 parts, boric acid 5~10 parts, water 10~25 parts.
Use the glue of the present invention, there is the advantage that tack is good, fastness is high;Fire retardant of the present invention not only good flame retardation effect, and the tack of glue with remaining the component Synergistic in glue, can be increased.
As preferably, also include grey cloth is moved back before mordanting and coating and boil drift and mercerization finish, described moving back is boiled drift and is included moving back and boil and oxygen bleaching, drift combined production line is boiled in employing, after using six lattice adverse current open washings, fabric is carried out roll compacting with control moisture content as 45-55%, the most directly pad liquid lime chloride and make fabric decatize bleach;Speed during described oxygen bleaching is 58-65m/min, described oxygen bleaching method be fabric is placed in oxygen bleaching liquid and in pressurized vessel repeatedly pressurize, decompression operation, the bath raio of oxygen bleaching liquid is 3-5:1, and described oxygen bleaching liquid is hydrogen peroxide and the water composition of refining agent OPE, 8-10g/L of the sodium carbonate of 6-10g/L, the disodium hydrogen phosphate of 2-3g/L, the sodium silicate of 1-3g/L, the sodium lauryl sulphate of 4-6g/L, 2-5g/L;In described pressurization should make pressurized tank, temperature reaches 95-105 DEG C, and described decompression is quickly to discharge the pressure in this pressurized tank to air after pressurized, heated;Described mercerising is to use the rate auto-controller containing tide to make fabric contain tide rate to control at 25-35%, carries out semi-moist mercerising in the mercerising solution comprising 265-300g/L sodium hydroxide, 5-8g/L alkylol sulfuric ester sodium salt.
Use the method described grey cloth can carry out process and remove impurity thereon, be prevented from polyster fibre simultaneously and spandex core-covered high temperature is impaired and strength declines;By traditional moving back, boil, bleaching process is reduced to a step and boils drift associating, reduces terylene and the damage of spandex, further reduces waste water and produce;Using boiling drift and can shortening the time of the present invention, rapid pressure change boils drift, improves the comfortable feel of grey cloth further.
As preferably, described post processing is included in 165-170 DEG C of drying for the first time, dries in 170-175 DEG C of second time drying and 175-180 DEG C of third time, then lowers the temperature with cold wind.
High temperature is dried and can be separated by some nuisances, improves color fastness;Dry step by step and can improve color fastness further.
It is highly preferred that with cold wind cooling specifically with the cold wind cooling 25-40min of 80-100 DEG C;Then with the cold wind cooling 15-20min of 50-70 DEG C;Finally cool down at room temperature.
Cold wind cooling step by step is used to can further improve again coloring effect and color fastness.
