Abstract
The invention discloses a normal-pressure dyeing method of a fragrant polyester/polyurethane knitting fabric. The normal-pressure dyeing method of the fragrant polyester/polyurethane knitting fabric comprises the following steps of: A, preparing dye liquor: weighing 1-4% (owf) of disperse dye, mixing the materials by using water at 30-40 DEG C based on the bath ratio of (10-40):1, adding 10-15g/L of vanillin while stirring, and raising the temperature to 50 DEG C to prepare the dye liquor; B, dyeing: adding polyester/polyurethane fabric subjected to pretreatment in the dye liquor, raising the temperature to 90-95 DEG C at the speed of 1.5-2 DEG C/min, insulating for 40-60min and dyeing, wherein the dyeing time and insulating time are determined based on the color required, and the darker the color is, the longer the dyeing time and insulating time are; and C, after dyeing, washing the dyed polyester/polyurethane fabric with hot water at 60 DEG C for twice, then carrying out reduction cleaning by using reduction liquid at 50 DEG C for 30min, washing for twice, dehydrating and carrying out heat shaping. By using the method, the polyester/polyurethane knitting fabric has a certain aromatic property, and the damage caused by high-temperature and high-pressure dyeing as well as peculiar smell and toxicity generated when an ordinary carrier is dyed is avoided.
Description
Technical field
The present invention relates to a kind of colouring method of washing the ammonia knit fabric, particularly Fang Xiang the colouring method of washing the ammonia knit fabric.
Background technology
Wash the ammonia knitted fabric and be rich in elasticity, be subjected to very much the favor in American-European market.Wash the dyeing of ammonia knitted fabric at present and adopt DISPERSE DYES high-temperature pressure dyeing method more.Contain spandex fabric under the condition of high temperature, acid, alkali, under the impact of liquid stream, very easily aging, embrittlement and produce disconnected spandex defect causes the substandard products that can't repair.
The low temperature dyeing effect of polyster fibre conventional carriers is very good, has all passed through long-term practice test such as these representational commodity carriers such as wintergreen, swelling agent OP, swelling agent MN.But still there are some defectives in these carriers, and the Chinese ilex main body of oil is gaultherolin, and its price height, smell are big, volatile, need closed-loop operation; The main component methyl naphthalene of swelling agent MN though price is low, easy to use, has strong camphor stink, and especially smell is stronger when blanching is finalized the design, and the workman can't be stood; The main component of swelling agent OP is the o-phenyl phenol sodium salt, and carrier residual after its dyeing is influential to light fastness.Therefore to adopt the carrier of " environmental protection " type.
Vanillic aldehyde (vanillin) is the human first kind of essence that is synthesized, and has another name called vanillic aldehyde.Chemical name 3-methoxyl group-4-hydroxy benzaldehyde, appearance white or little yellow crystal have vanilla fragrance and strong milk, are kind maximum in the perfume industry, are the Main Ingredients and Appearances of the cream vanilla generally liked of people.Its purposes is very extensive, as in food, daily use chemicals, tobacco industry as spices, flavor enhancement or fixastive, wherein food consumptions such as beverage, candy, cake, biscuit, bread and roasted seeds and nuts are in the majority.Vanillic aldehyde also is used for plant growth promoter, bactericide, lubricating oil antifoams, brightening agent, printed wiring board production conductive agent etc. abroad in a large number for the production of medicine intermediate.Also there is not the harmful relevant report of vanillic aldehyde.
Summary of the invention
The objective of the invention is in order to overcome above deficiency, provide a kind of can making to wash the ammonia knit fabric and when obtaining satisfied color and luster, have certain armaticity, the dyeing at normal pressure method of washing the ammonia knit fabric of the peculiar smell when having avoided damage that high-temperature pressure dyeing produces and general carrier dyeing and the fragrance of toxicity.
Purpose of the present invention is achieved through the following technical solutions: a kind of dyeing at normal pressure method of washing the ammonia knit fabric of fragrance, and described colouring method may further comprise the steps:
A, preparation dye liquor: take by weighing DISPERSE DYES 1-4%(owf), draw material by bath raio 10～40:1 with 30～40 ℃ of water, add the vanillic aldehyde of 10～15g/L then while stirring, be warming up to 50 ℃ simultaneously, be mixed with dye liquor;
B, dyeing: in dye liquor, add and to wash the ammonia fabric through pre-treatment, speed with 1.5～2 ℃/min is warming up to 90～95 ℃ then, insulation 40～60min dyes, as required color and luster selective staining time and temperature retention time, and color and luster more deep dyed color time and temperature retention time is more long;
After C, dyeing finish, will wash the ammonia fabric earlier with 60 ℃ of hot water wash twice after the dyeing, use reducing solution reduction cleaning 30min under 50 ℃ condition again, wash twice again, carry out HEAT SETTING after the dehydration.
Further improvement of the present invention is: described DISPERSE DYES is low form or middle warm type DISPERSE DYES.
Further improvement of the present invention is: described reducing solution comprises the sodium hydrosulfite of 2g/L and the soda ash of 2g/L.
Further improvement of the present invention is: described pre-treatment is oil removal treatment.
The present invention compared with prior art has the following advantages: with nontoxic, can widely used vanillic aldehyde be spices and carrier, dye under 90 ~ 95 ℃, neutrallty condition with DISPERSE DYES, when obtaining satisfied color and luster, has certain armaticity, peculiar smell and toxicity when having avoided damage that high-temperature pressure dyeing produces and general carrier dyeing.
