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 ammonia knit fabric, particularly the colouring method of washing ammonia knit fabric of fragrance.
Background technology
Wash ammonia knitted fabric and be rich in elasticity, be subject to very much the favor of European & American Market.The dyeing of washing at present ammonia knitted fabric adopts DISPERSE DYES high-temperature pressure dyeing method more.Containing 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 cannot repair.
The low temperature dyeing effect of polyster fibre conventional carriers is very good, such as these representational commodity carriers such as wintergreen, swelling agent OP, swelling agent MN have all passed through long-term practice test.But these carriers still exist some defects, Chinese ilex main body of oil is gaultherolin, and its price is high, smell is large, volatile, needs closed-loop operation; The main component methyl naphthalene of swelling agent MN, although price is low, easy to use, has strong camphor stink, and especially in the time that blanching is shaped, smell is stronger, and workman cannot be stood; The main component of swelling agent OP is o-phenylphenol sodium salt, and after its dyeing, residual carrier has impact to light fastness.Therefore to adopt the carrier of " environmental protection " type.
Vanillic aldehyde (vanillin) is the first essence of mankind's synthesized, has another name called vanillic aldehyde.Chemical name Vanillin, appearance white or micro-yellow crystal, have vanilla fragrance and strong milk, is kind maximum in perfume industry, is the Main Ingredients and Appearance 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 the food consumption such as beverage, candy, cake, biscuit, bread and roasted seeds and nuts is in the majority.Vanillic aldehyde, abroad in a large number for the production of medicine intermediate, is also produced conductive agent etc. for plant growth promoter, bactericide, lubricating oil antifoams, brightening agent, printed wiring board.Also there is no the harmful relevant report of vanillic aldehyde.
Summary of the invention
The object of the invention is in order to overcome above deficiency, provide a kind of and can make to wash ammonia knit fabric and when acquisition is satisfied with color and luster, there is certain armaticity, the peculiar smell while having avoided damage that high-temperature pressure dyeing produces and general carrier dyeing and the fragrant dyeing at normal pressure method of washing ammonia knit fabric of toxicity.
Object of the present invention is achieved through the following technical solutions: a kind of dyeing at normal pressure method of washing ammonia knit fabric of fragrance, and described colouring method comprises the following steps:
A, preparation dye liquor: take DISPERSE DYES 1-4%(owf), draw material by bath raio 10～40:1 with 30～40 DEG C of water, then add while stirring the vanillic aldehyde of 10～15g/L, be warming up to 50 DEG C simultaneously, be mixed with dye liquor;
B, dyeing: in dye liquor, add and to wash ammonia fabric through pre-treatment, then be warming up to 90～95 DEG C with the speed of 1.5～2 DEG C/min, insulation 40～60min dye, color and luster selective staining time and temperature retention time as required, color and luster more the deep dyed color time and temperature retention time longer;
After C, dyeing finish, the ammonia fabric of washing after dyeing is first used to 60 DEG C of hot water wash twice, then use reducing solution reduction cleaning 30min under the condition of 50 DEG C, then wash twice, after dehydration, carry out HEAT SETTING.
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: taking nontoxic, can widely used vanillic aldehyde as spices and carrier, under 90 ~ 95 DEG C, neutrallty condition, dye by DISPERSE DYES, when being satisfied with color and luster, acquisition there is certain armaticity, peculiar smell and toxicity while having avoided damage that high-temperature pressure dyeing produces and general carrier dyeing.
