Description
Technical field
The present invention relates to the dyeing of cloth, more particularly to a kind of dyeing processing technique of woollen sweater.
Background technology
Wool is a kind of excellent natural protein fibre, with its excellent hygroscopicity, elasticity, gas permeability, warmth retention property, is relaxed
Adaptive and unique ready-made clothes effect and it is very popular.Wool surfaces are had the scale layer of direction friction effect to cover,
In hydrophobic property, dye liquor is not easy to soak, and hinders the absorption and diffusion of dyestuff so that woollen sweater usually dyes in dyeing
Irregular and low dyefastness phenomenon.
Patent CN105568594B discloses a kind of woolen sweater dyeing machine, it includes rack, and rotating cylinder is provided in rack,
External in rotating cylinder coats crust body, and the actuating unit being sequentially connected with rotating cylinder is provided in rack, is set in rack
It is equipped with dyestuff atomising mechanism, air pressure balance mechanism and steam heating mechanism；What is be spaced on the inner wall of rotating cylinder is provided with two pieces of masters
Baffle is provided with one piece of secondary baffle between adjacent master shield, one or more is provided on the radial end face of master shield
Radial driving lever；Wherein the rotating cylinder between one group of adjacent master shield and secondary baffle, there are one feeding gates for setting on outer housing.
The processing dyed to woollen sweater using above-mentioned woolen sweater dyeing machine can be realized effectively and be contaminated woollen sweater using rotating cylinder
Color helps to reduce woollen sweater in dyeing course the phenomenon that uneven dyeing, but dyefastness is still undesirable.
Patent CN107299544A's discloses a kind of woolen sweater dyeing technique, which includes：Pretreatment, surface are modified
Processing, dyeing and four processes of fixation, although helping to improve colour fixation, the process of surface modification treatment is complicated, right
The equipment requirement of surface modification treatment is higher, increases the dyeing cost of woollen sweater.
Invention content
The purpose of the present invention is to provide a kind of dyeing processing technique of woollen sweater, have the advantages that dyefastness is good.
The present invention above-mentioned technical purpose technical scheme is that.
A kind of dyeing processing technique of woollen sweater, includes the following steps：
Step 1, woollen sweater is immersed in neutral protein enzyme solutions by the pretreatment of woollen sweater, is carried out in preprocessing solution, 40
10~20min is pre-processed at~50 DEG C；
Step 2, dye, step 1 treated woollen sweater immersed in the dye liquor of dye vat, at 50~60 DEG C constant temperature processing 30~
After 60min, color fixing agent is added into dye vat, is added after color fixing agent, with the heating rate of 1~2 DEG C/min, by dye liquor and fixation
The mixed liquor of agent is warming up to 70~80 DEG C and keeps 10~20min；
Step 3, it cleans, by step 2, treated that woollen sweater is carried out dehydrating, and then utilizes the woollen sweater after dehydration
Cleaning solution is cleaned；Woollen sweater after cleaning is drained naturally, obtains the woollen sweater for completing dyeing.
Preferably, in the neutral protein enzyme solutions neutral proteinase a concentration of 0.8g/L~1.2g/L；The neutrality
The mass ratio of protein enzyme solution and woollen sweater is (5~10)：1.
Through the above technical solutions, woollen sweater is pre-processed using neutral protein enzyme solutions before dyeing, it is neutral
Protease can make the intercellular binding of wool scale layer degrade, and help to expand the duct on wool scale layer, be carried for dyeing
For dyeing channel, contribute to dye liquor that scale layer is passed through so that dye liquor is combined even closer, Jin Eryou with wool into wool
Help improve the dyefastness after woolen sweater dyeing.
Dyeing course is divided at 50~60 DEG C constant temperature processing and reinforces after toner that constant temperature handles two at 70~80 DEG C
Stage helps to improve absorption of the dye liquor on wool, and then conducive to the dyefastness of raising woollen sweater.
Preferably, it after woollen sweater being immersed neutral protein enzyme solutions in the step 1, is passed through into neutral protein enzyme solutions
Ozone.
Through the above technical solutions, ozone is passed through in neutral protein enzyme solutions, ozone has strong oxidizing property, helps to open
The part 2S keys of wool scale layer contribute to the place for making neutral proteinase be adsorbed in the destruction of 2S keys, and are conducive to neutral proteinase
Into in wool, the scale layer of wool is on the one hand opened, the upper dye position of wool is on the other hand increased, helps to improve
Contaminate rate.Ozone is different from the substance of other Strong oxdiative classes, safe and nontoxic, is generated without harmful liquid, gives up after more conducively dyeing
The processing of water.
Preferably, the dye liquor is made of the raw material of following parts by weight：Reactive dye, water, polyoxyethylene-type nonionic
Type surfactant, a concentration of 0.6~0.8g/L of the reactive dye, the Polyoxyethylene nonionic surfactant
A concentration of 0.1~0.5g/L.
Preferably, the bath raio of the dye liquor and woollen sweater is (10~20):1；The mass ratio of the color fixing agent and dye liquor is
(1~2)：100.
Through the above technical solutions, Polyoxyethylene nonionic surfactant is used as levelling agent, polyoxyethylene
Ehter bond in type nonionic surface active agent forms Hydrogenbond with water first, is then reacted again with dye molecule, generates and lives
The smaller hydrogen-bonded adduct of property.Hydrogen-bonded adduct decomposes during heating, dyestuff is released, to play the work of level dyeing
With.Color fixing agent and reactive dye cross-linking reaction, to help to reinforce the dyefastness of woollen sweater.
Preferably, the cleaning solution is made of the chitosan, 0.05~0.1g/L glacial acetic acid and water of 0.08~0.13g/L；
The mass ratio of the cleaning solution and the woollen sweater after dehydration is (3~6)：1.
Through the above technical solutions, the addition of chitosan, contributes to the scale layer for making wool open to bond, closing dye is played
The loss of dyestuff is reduced, and then improve the dyefastness of woollen sweater to play the effect of lock color in chrominance channel.Glacial acetic acid
Addition keeps cleaning solution weakly acidic, and the condition of weak acid contributes to the dissolving of chitosan.
Preferably, the method for dehydration is to utilize compression roller extrusion dehydration in step 3.
The processing of dehydration reduces the excess dyestuff on woollen sweater after dip dyeing, helps to reduce in follow-up clean operation
Water consumption.The mode of extrusion dehydration is different from the dewatering type of centrifugal dehydrator, squeeze influence to wool scale layer be less than from
Influence of the heart to wool scale layer, reparation of the more conducively follow-up cleaning solution to scale layer, to play the work for improving dyefastness
With.
Preferably, it is heated up to the mixed liquor of dye liquor and color fixing agent using the method for microwave heating in the step 2.
Microwave helps to improve the activity of reactive dye, the more conducively combination of reactive dye and woollen sweater；Microwave heating
Mode coordinates 70~80 DEG C of temperature, contributes to and neutral proteinase is made to lose activity, and after contributing to dip dyeing to complete, dyeing is logical
The effect for improving dyefastness is played in the closing in road.
In conclusion the invention has the advantages that：
1, neutral proteinase and ozone coordinate, and are pre-processed to woollen sweater, help to expand the dyeing channel on wool, more sharp
Enter in wool in dye liquor；
2, the cooperation of chitosan and glacial acetic acid, the scale layer of wool after contributing to reparation to disseminate, plays the effect of lock color；
3, the operation of compression roller extrusion dehydration and microwave heating each contributes to improve the dyefastness of woollen sweater.
