Description
Technical field
The present invention relates to the field that dyeing use REACTIVE DYES mixing alkaline agent carries out cold-rolling heap staining, especially a kind of fast proofing method for cold-rolling heap staining.
Background technology
Dyeing uses REACTIVE DYES mixing alkaline agent to carry out cold-rolling heap staining production, needs during this time stacking at room temperature about 24 hours, just can complete dyeing.And full-page proof often needed to beat sample before cold-rolling heap staining, to determine dyeing prescription, dyeing when full-page proof cold-rolling heap staining is produced, if but cold-rolling heap staining is beaten sample and is also adopted with full-page proof cold-rolling heap staining and produce the same stacking at room temperature 24 hours, tend to incur loss through delay the full-page proof cold-rolling heap staining production schedule because beating sample overlong time, finally incured loss through delay the product time of delivery.
For this reason, many printing and dyeing producer is all actively groping how to shorten cold-rolling heap staining and is beating the method for sample time, the at present more employing micro-wave oven of the printing and dyeing producer method of drawing a design, the baking oven method etc. of drawing a design, but owing to beating the cotton color of sample and the larger aberration of cotton color existence of full-page proof production, and same dyeing prescription, dyeing, repeat to beat between the cotton color batch of sample at every turn and also exist larger aberration, its reason is that above-mentioned these method of drawing a design all exists dyeing temperature and cannot stably be controlled at identical conditions, dyeing temperature fluctuation is larger, cause beating the cotton color of sample and the larger aberration of cotton color existence of full-page proof production.Therefore, look often will be repaiied after full-page proof cold-rolling heap staining is produced by printing and dyeing mill, has had a strong impact on like this raising of quality stability and the production efficiency of product.
The domestic problem of the larger aberration of cotton color existence produced of cotton color and full-page proof that adopts the water bath with thermostatic control method of drawing a design to solve to beat sample that also had document or patent report, although obtained significant progress, still there is certain aberration in the cotton color of putting into practice cotton color and the full-page proof production of beating sample.This is mainly also not too to approach because of beating little sample testing situation and condition actual state and the condition that full-page proof is produced.In addition, also ignored the cold rolling heap alkaline agent of REACTIVE DYES hydrolysis of reactive dye has been affected to this key factor.
Summary of the invention
The present invention is directed to above-mentioned defect, a kind of fast proofing method for cold-rolling heap staining is provided, simple to operate, process equipment requires low, can effectively shorten the time of beating sample, reduces the aberration of the cotton color of sample and the cotton color existence that full-page proof is produced.
For this reason, the present invention takes following technical scheme, and a kind of fast proofing method for cold-rolling heap staining, comprises the following steps:
(1) the preparation reactive pad dyeing solution consistent with full-page proof factory formula, REACTIVE DYES, osmotic agent solution made to use up after mixing with the cold rolling heap alkaline agent of REACTIVE DYES in 40-90 minute;
(2) according to producing consistent dip time, pick-up rate with full-page proof, sample cotton one is soaked to one and roll;
(3) the hand sample dyeing cotton after pad dyeing is reeled along the long glass bar of fabric width identical with it, put into the plastic sealing bag matching with it, and extract the gas in plastic bag out, keep sealing;
(4) hand sample dyeing cotton plastic sealing bag first will be housed, put into gently 20-40 DEG C of water-bath, sealing opening of plastic bag will be higher than liquid level, and insulation was banked up after 20-60 minute, plastic sealing bag is proposed gently again, put into gently 40-70 DEG C of water-bath, insulation was banked up after 20-60 minute, then proposed gently plastic sealing bag, put into gently 20-40 DEG C of water-bath, insulation was banked up after 5-30 minute, proposed gently plastic sealing bag, took out dyeing cloth specimen;
(5) according to producing consistent washing with full-page proof, soap, washing process dyes post processing, then will after the oven dry of hand sample dyeing cotton, pressing, balance, check colors.
The cold rolling heap alkaline agent of described REACTIVE DYES, by forming for alkaline constituents, buffer components and filling components, wherein comprises NaOH, potassium hydroxide, sodium carbonate, potash, tertiary sodium phosphate for alkaline constituents; Buffer components comprises sodium metasilicate, sodium metasilicate, sodium bicarbonate, saleratus, sodium hydrogen phosphate, calgon, trisodium citrate, potassium sodium tartrate; Filling components comprises sodium chloride, potassium chloride, sodium sulphate, potassium sulfate.
As preferably: reactive pad dyeing solution in step (1), REACTIVE DYES, osmotic agent solution made to use up after mixing with the cold rolling heap alkaline agent of REACTIVE DYES in 60 minutes, hand sample dyeing cotton plastic sealing bag first will be housed in step (4), put into gently 30 DEG C of water-baths, insulation was banked up after 30 minutes, plastic sealing bag is proposed gently again, put into gently 60 DEG C of water-baths, insulation was banked up after 30 minutes, propose gently plastic sealing bag again, put into gently 30 DEG C of water-baths, insulation was banked up after 15 minutes, propose gently plastic sealing bag, take out dyeing cloth specimen.
In step (1) because REACTIVE DYES was hydrolyzed quite slow in 40-90 minute, in the meantime, make the pad dyeing solution of using up, can avoid REACTIVE DYES under alkali condition because of too fast hydrolysis, uncontrollable hydrolysis rate and cause the generation of this situation of color that cannot be the accurately corresponding full-page proof of color of beating sample produces.While doing little sample testing, according to producing consistent dip time, pick-up rate with full-page proof, sample cotton one is soaked to one and roll, can approach very much actual state and condition that full-page proof is produced.
In step (2), the hand sample dyeing cotton after pad dyeing is reeled along the long glass bar of fabric width identical with it, put into the plastic sealing bag matching with it, and drive the gas in plastic bag away, sealing.Do like this little sample testing and can approach very much actual state and the condition that full-page proof is produced, and can avoid hand sample dyeing cotton pasting plastic bag because of monoblock, the dye liquor on cotton is easily infected with plastic bag unevenly and is caused the final dyeing of cotton inhomogeneous.
It is mainly the stacking at room temperature environment that simulation full-page proof is produced that the first stage of step of the present invention (4) and phase III bank up with 20-40 DEG C of water bath heat preservation, and second stage is banked up with 40-70 DEG C of water bath heat preservation, the time of banking up can be shortened greatly, find the very accurately color of corresponding full-page proof production of color of its dozen of samples through groping test, CMC DE≤1, and fix because of dyeing temperature, dyeing time, adopt same dyeing prescription, dyeing, repeat to beat sample, the aberration between its batch there is no significant change at every turn.
The present invention has researched and solved the cold rolling heap alkaline agent of REACTIVE DYES affects this major issue to hydrolysis of reactive dye, secondly approach as much as possible by beating little sample testing situation and condition actual state and the condition that full-page proof is produced, bank up by 40-70 DEG C of water bath heat preservation in centre, greatly to shorten the time of banking up.
Beneficial effect of the present invention is as follows:
(1) simple to operate, process equipment requires simple;
(2) adopt the fast proofing new method of this cold-rolling heap staining, can greatly shorten and beat the sample time, front and back operated about approximately 2 hours, just can complete dozen little sample testing.
