Above-mentioned blue or green floss discoloration method, the action principle of each auxiliary agent is as follows:
A, enzyme are washed in step:
1. in enzyme is washed, the purpose of nonionic lotion is to remove the oils and fats on blue or green floss surface, dirt, gives full play to mercerising protease and plays a role.
2. in enzyme is washed, regulate pH value 8-9, give full play to mercerising protease and play a role.
3. adding mercerising protease in enzyme is washed is to remove the secondary protein on cashmere fiber surface and hydrolyzed protein, effectively gets through second step pretreatment ferrous ion and enters the passage within cashmere fiber.
In B, pre-treatment step:
1. the take a policy purpose of powder of pretreatment is the reducing environment maintaining treatment fluid, prevents ferrous ion to be oxidized to insoluble ferric ion.
2. the alkali remained in regulation PH=4-5 and when enzyme is washed, as used acetic acid to regulate.
3. add the purpose of chelating agent
(1) efficient complexation ferrous ion, and ferrous ion forms coordinate bond and combines, and shields the positive charge around ferrous ion, decreases the damage to fiber of the positive charge ferrous ion, eliminate fiber protection agent.
(2) adding chelating agent makes treatment fluid stable: owing to chelating agent makes the surrounding of ferrous ion present elecrtonegativity, add the water solublity of ferrous ion, stability, experiment finding, the treatment fluid adding chelating agent is the limpidest, and does not add the treatment fluid surface of chelating agent due to air oxidation jaundice, muddiness；
(3) ferrous ion is made to change charged character (negative charge) after adding chelating agent so that ferrous ion more easily enters fiber and pigment combines.During owing to adding acetic acid in second step, cashmere surface is positively charged, in electronegative complexation ferrous ion because attractive coulombic force electrical attraction (having got through passage owing to adding enzyme in the first step) more easily enters fiber combines (pigment in blue or green floss is better than chelating agent and ferrous ion binding ability with the ability that ferrous ion combines) with pigment；
(4) jointly act on due to chelating agent and first step ferment treatment so that the effective rate of utilization of ferrous salt increases, and decreases ferrous salt consumption, reduces cost, decreases the washing time after second step,
(5) use chelating agent make not with ferrous ion and the chelating agent generation complexation of the excess of pigment complexation, the ferrous ion good water solubility of complexation, be prone to rinse, decrease washing time, it is to avoid the unnecessary iron ion catalysis damage to fiber in oxygen bleaching.More than original at least flushing 5 cylinder water, it is reduced to have only to rinse 1-2 cylinder water；
In C, oxygen bleaching step:
1. adding stabilizer is to maintain a stable pH environment, it is to avoid during oxygen bleaching, iron ion is excessively catalyzed.
2. damage cashmere fiber when the purpose of addition fiber protection agent is to prevent oxygen bleaching.
3. adding hydrogen peroxide is to bleach, owing to the comparison of the second step ferrous ion after improving and pigment complexation is abundant, therefore new technology hydrogen peroxide consumption is by original opposed fabric weight 60%, it is reduced to opposed fabric weight about 30%, save the hydrogen peroxide of half, reducing cost, bleaching time was shortened to 60 minutes by original 90 minutes, decreased the damage to fiber.
In D, reduction step:
1. the purpose adding formic acid is the residual alkali in order to neutralize oxygen bleaching, controls the condition of reduction to carry out under sour environment, and formic acid has certain reproducibility, beneficially ferric ion to be reduced into ferrous ion.
2. the purpose of powder of taking a policy is the reducing environment maintaining treatment fluid, the hydrogen peroxide that reduction is not rinsed well.The ferrous ion that insoluble ferric ion oxygen bleaching caused is reduced into.
3. the purpose adding chelating agent is to make ferrous ion complexation disperse, more fully (traditional method uses oxalic acid to go iron ions to make iron ions, owing to the corrosivity of oxalic acid is strong, cashmere feel after process is very poor), even and if have minimal amount of iron ion to remain, not interfering with the coloured light (metal ion can cause dyeing after gloomy) of rear road dyeing owing to iron ion is complexed, unnecessary chelated iron ion is rinsed removal after having dyeed.Therefore, the method protects the feel of fiber, strongly, adds the whiteness of final fiber.
Above-mentioned blue or green floss discoloration method, has the following characteristics that
1, in front washing, add mercerising protease and remove secondary protein and the hydrolyzed protein on cashmere fiber surface, effectively get through second step pretreatment ferrous ion and enter the passage within cashmere fiber.
2, add a kind of compound complex agent during pretreatment, be not only pretreatment fluid stable, and make ferrous salt consumption reduce, decrease the washing time after second step.
3, during oxygen bleaching, hydrogen peroxide consumption reduces a lot, and bleaching time shortens, and reduces cost.Owing to the comparison of the second step ferrous ion after improving and pigment complexation is abundant, therefore new technology hydrogen peroxide consumption is by original opposed fabric weight 60%, it is reduced to opposed fabric weight about 30%, save the hydrogen peroxide that half is many, reduce cost, bleaching time was shortened to 60 minutes by original 90 minutes, decreased the damage to fiber.
4, reducing bleach employs the 2-cyclopenten-2,3-diol-1-one .-formic acid of small-molecular-weight instead of composite decoloration acid and reduce cost, be simultaneously used a small amount of efficient chelating agent so that go removing rust more abundant, protect fiber strength, add the whiteness of final fiber.
Compare the blue or green floss decoloration process of routine, the invention have the advantages that
One, introduce biological enzyme technology, front washing adds mercerising protease.
Enzyme is always the emphasis of textile science research, and biological enzyme formulation has the distinguishing features such as single-minded, efficient, environmental protection.(this mercerising protease is for Pilus Caprae seu Ovis mercerising soft treatment for the mercerising protease used in present invention process, in the washing pre-treatment extended) consumption is considerably less, but effectively get through second step pretreatment ferrous ion and entered the passage within cashmere fiber, effectively processed for second step and lay a good foundation.
Two, efficient chelating agent has been selected during pretreatment.
This efficient chelating agent can efficient complexation ferrous ion, and ferrous ion forms coordinate bond and combines, and shields the positive charge around ferrous ion.The benefit using this efficient chelating agent to bring has:
The fiber protection agent used in A, the former technique eliminated.Owing to the positive charge of ferrous ion is shielded, decrease the damage to fiber of the positive charge ferrous ion.Therefore, this step eliminates fiber protection agent, in its postpose oxygen bleaching, uses the best steel to make the knife's edge, reduce fibre damage；
B, the treatment fluid adding efficient chelating agent are stable.Owing to efficient chelating agent makes the surrounding of ferrous ion present elecrtonegativity, add the water solublity of ferrous ion, stability, experiment finding, the treatment fluid adding efficient chelating agent is the limpidest, and does not add the treatment fluid surface of efficient chelating agent due to air oxidation jaundice, muddiness；
Make ferrous ion more easily enter fiber after C, addition chelating agent and pigment combines.During owing to adding acetic acid in second step, cashmere surface is positively charged, in electronegative ferrous ion because attractive coulombic force electrical attraction (and in the first step, addition enzyme has got through passage) more easily enters fiber with pigment complexation；
D, jointly act on due to efficient chelating agent and first step ferment treatment so that the consumption of ferrous salt decreases 3/4, and the time of second step pretreatment is greatly shortened, and is reduced to about 40 minutes by original 120 minutes.Simultaneously because the consumption of ferrous salt reduces, decrease the washing time after second step, more than original at least flushing 5 cylinder water, be reduced to have only to rinse 2 cylinder water；
Three, during oxygen bleaching, hydrogen peroxide consumption reduces a lot, and bleaching time shortens, and reduces cost.
Owing to the comparison of the second step ferrous ion after improving and pigment complexation is abundant, therefore present invention process hydrogen peroxide consumption is by original opposed fabric weight 60%, it is reduced to opposed fabric weight 30%, save the hydrogen peroxide that half is many, reduce cost, bleaching time was shortened to 60 minutes by original 90 minutes, decreased the damage to fiber.
Four, reducing bleach employs the 2-cyclopenten-2,3-diol-1-one. (formic acid) of small-molecular-weight instead of composite decoloration acid and reduce cost, be simultaneously used a small amount of efficient chelating agent so that go removing rust more abundant, protect fiber strength, add the whiteness of final fiber.
