Description
Technical field
The present invention relates to cashmere processing technique field, especially a kind of improved cashmere color-fixing method.
Background technology
Cashmere after dyeing, needs to carry out the loose colour on its surface process removal, improves the fastness of dyeing.Existing skill
The processing method that art is provided is to carry out fixation treatment to dyestuff by adding color fixing agent.Because some dyestuff is in dyeing rank
Duan Bingwei and cashmere form firm chemical bonded, so only process by color fixing agent cannot realize that dyestuff is really tied with cashmere
Close, colour fixation is not good.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of improved cashmere color-fixing method, can solve the problem that prior art
Deficiency, improves the colour fixation of cashmere.
To solve above-mentioned technical problem, the technical solution used in the present invention is as follows.
A kind of improved cashmere color-fixing method, comprises the following steps：
A, the cashmere after dyeing is put in the pure water of flowing is rinsed, remove the part loose colour on cashmere surface；
B, cashmere is put in processing pond, adds pure water, then the cashmere per 1000 parts of parts by weight adds following weight
The dosage component of number：
2～7 parts of polyoxyethylene fatty amine, 3～5 parts of neopelex, 10～20 parts of sodium chloride, 5～7
1,3- acetone dicarboxylic acid diethylesters, 10～15 parts of the 2- piperazine ketone, 7～10 parts of stearylmercaptan, 1～2 part of 2,5- of part
Mesitylenic acid, 2～10 parts of benzidine and 15～30 parts of disodium succinate；
Cashmere in processing pond is stirred, while water temperature risen to into 70～80 DEG C, is kept for 3～5 hours, make liquid with
Cashmere surface does not form the bonded dyestuff of chemistry with cashmere and fully reacts, and forms solid-state complex；
C, cashmere is taken out from processing pond, tiling is positioned in drier and is dried, baking temperature control 250～
300 DEG C, the moisture evaporation that cashmere surface is contained after being dried disappears, and the solid-state complex for being attached to cashmere surface is given birth on cashmere surface
Into cured layer；
D, cashmere surface sprinkling pharmaceutical dissolution after the drying, pharmaceutical dissolution includes the composition of following parts by weight：
5～10 parts of dicthenone, 3～7 parts to benzyl aminophenol, 15～25 parts of 1- fourth sulfonic acid, the three of 1～3 part
Fluoromethane sulfonic acid magnesium, 10～20 parts of 2,6- dichloro paracresol, 35～50 parts of methane sulfinic acid sodium, 20～30 parts of chloro oxime
Ethyl, 500～700 parts of ethanol, 1500～2000 parts of pure water；
E, the cashmere of pharmaceutical dissolution standing and drying at normal temperatures will be sprayed, while being passed through the sky that flow velocity is 3m/s～5m/s
Gas air-flow accelerates the evaporation of moisture；
F, will carry out rubbing process through the dried cashmere of step E, and the cured layer on its surface be crushed and is removed；
G, the cashmere after the process of step F is put in the pure water of flowing and is rinsed again, be then dried.
Preferably, in step B, cashmere is 2 with the bath raio of pure water:35.
Preferably, after step C is dried, it is right to the nitrogen that cashmere surface injection temperation is -15 DEG C～-25 DEG C
Cured layer is hardened, and makes cured layer crack occur.
Preferably, in step D, per kilogram cashmere sprays 25～40 grams of pharmaceutical dissolutions.
Preferably, pharmaceutical dissolution is divided into into 4 sprinklings, every time the 1/4 of sprinkling pharmaceutical dissolution total amount, quiet after sprinkling every time
Put 15～20min.
The beneficial effect brought using above-mentioned technical proposal is：The present invention makes loose colour produce network by adding medicament
Precipitation is closed, so that loose colour is completely separated with cashmere, physical removal is then carried out again so that loose colour produces more thorough with cashmere
Separation.Polyoxyethylene fatty amine and neopelex are separated to loose colour and cashmere, make not formed with cashmere
Whole chemical bonded loose colour forms aggregation group, in 2,5- mesitylenic acids, benzidine and 1,3- acetone dicarboxylic acid two
In the presence of ethyl ester, loose colour forms complex compound, and 2- piperazines ketone can improve dispersed homogeneous degree of the medicament in water, stearylmercaptan
Stability of the complex compound for generating in water is improved, sodium chloride can improve the stability for having cured the dyestuff on cashmere,
Disodium succinate is attached in complex compound, not only can improve susceptibility of the complex compound for low temperature, but also can protect sheep
Suede surface is not by low temperature injury.Pharmaceutical dissolution be used for complex compound generate cured layer decompose, be easy to subsequent step for
The removal of complexing layer.K cryogenic treatment is carried out to being complexed layer by using low temperature nitrogen, accelerates the division of complexing layer.
Specific embodiment
A kind of improved cashmere color-fixing method, comprises the following steps：
A, the cashmere after dyeing is put in the pure water of flowing is rinsed, remove the part loose colour on cashmere surface；
B, cashmere is put in processing pond, adds pure water, cashmere is 2 with the bath raio of pure water:35, then per 1000 parts of weight
The cashmere of number adds the dosage component of following portions by weight：
4 parts of polyoxyethylene fatty amine, 5 parts of neopelex, 12 parts of sodium chloride, 6 parts of 1,3- acetone
