Abstract
A method for dyeing cotton fiber fabric by multiple auxiliaries comprises steps as follows: dye, positive ions T, a dispersant CNF, nonionic alicyclic amine polyoxyethylene ether and an acid-base buffering agent are placed into a mixed liquid of an alcohol organic solvent and water and uniformly stirred to prepare a dye liquid; the dye liquid and the cotton fiber fabric are placed in a dyeing machine, the fabric is dyed at the temperature of 40 DEG C, heated at the speed of 1.5 DEG C per minute and subjected to thermal insulation dyeing; flaked soap and sodium carbonate are placed into the mixed liquid of the alcohol organic solvent and the water and stirred uniformly to prepare a washing solution; the dyed cotton fiber fabric is placed into the washing solution for washing; the cotton fiber fabric is dried and subjected to aftertreatment, stentering, preshrinking, cloth inspection and rolling. According to the method disclosed by the invention, three types of auxiliaries are matched for use, the staining property is not influenced while the dye-uptake rate and the fixation rate of dye to cotton fiber are remarkably increased; and the dyeing process is simple, environment protection is realized, the cost is lower, and the method is suitable for large-scale production.
Description
Technical field
The present invention relates to a kind of colouring method of cotton synthetic fibre fabric, particularly relate to a kind of method utilizing multiple auxiliary agent to carry out cotton synthetic fibre textile dyeing.
Background technology
At present, along with the raising day by day of people's living standard, the continuous renewal of consumption idea, the requirement of consumer to the quality, kind, color etc. of cotton synthetic fibre textiles, particularly fabric is more and more higher.Weak acid dye is the primary dye of cotton synthetic fibre dyeing, and when cotton/cotton or cotton/cotton mixture fabric adopt two bath methods or one-bath dyeing, faintly acid fuel can be infected with cotton fiber, causes the color fastness decreased of cotton/cotton or cotton/cotton mixture fabric, even has influence on the vividness of color.
Meanwhile, conventional cotton synthetic fibre colouring method is higher than in the dyeing installation of 100 DEG C, carries out damp and hot dyeing.The solvent normally water of DISPERSE DYES, in actual production, the dispersive property of dyestuff declines, and dyestuff is meeting secondary aggregation in course of dissolution, or on dye thing, forms the dye defects such as look flower, color spot, barriness because fastness difference, affects quality.
In sum, the cotton synthetic fibre fabric dyeing method of dyeability can be improved in the urgent need to one at present, the compatibility of fuel can be provided, and improve the dyeability of dyestuff and reduce staining.
Summary of the invention
CATION T is the cationic of cetyl bi-quaternary ammonium salt, has stronger emulsifying capacity, has good compatibility with nonionic and amphoteric surfactant, can increase the dyeing ability to cotton synthetic fibre, and less to the staining of cotton synthetic fibre.Dispersing agent C NF is the anionic of benzyl naphthalenesulfonate formaldehyde condensation compound, and diffusivity is good, without permeability and foaming characteristic.Acid and alkali resistance, salt and hard water, Heat stability is good, dispersing agent C NF can give and improve dyestuff to the dyeing ability of cotton synthetic fibre, but also can increase the staining to cotton synthetic fibre simultaneously.The aliphatic amine polyoxyethylene ether of nonionic has excellent level dyeing, diffusion, it is reducing dye levelling agent, and dye rapidly under contributing to high temperature, the staining of dyestuff to cotton synthetic fibre can be reduced, but also can increase and decrease few dyestuff to the dye-uptake of cotton synthetic fibre and fixation simultaneously.This three kinds of auxiliary agents collocation is used, effectively can improve the dyeability of cotton synthetic fibre and reduce cotton synthetic fibre staining.Again due to ethanol as dye solvent, when temperature is higher than cotton synthetic fibre vitrification point, the strand that can increase its surface is movable, increases the hole holding dye molecule.Promote that dyestuff is adsorbed by cotton synthetic fibre fabric.
For achieving the above object, technical scheme provided by the present invention is:
Utilize a cotton synthetic fibre fabric dyeing method of CATION T, dispersing agent C NF, comprising:
1) aliphatic amine polyoxyethylene ether of dyestuff, CATION T, dispersing agent C NF, nonionic and acid-base buffer agent are placed in the mixed liquor of alcohol organic solvent and water, after stirring, make dye liquor;
2) dye liquor and cotton synthetic fibre fabric are placed in dyeing machine, 40 DEG C enter dye, heat up with 1.5 DEG C/min, insulation dyeing;
3) soap flakes and sodium carbonate are placed in the mixed liquor of alcohol organic solvent and water, stir and make cleaning solution;
4) by step 2) in the complete cotton synthetic fibre fabric of dyeing put into cleaning solution and wash;
5) dry, post processing, tentering, preshrunk, cloth-inspecting rolling.
Further, in step 1) described in the bath raio of dye liquor be 1:25-1:45, the volume ratio of alcohol organic solvent and water is 75-50%:25%-50%, the concentration of CATION T is 0-0.5g/L, the concentration of dispersing agent C NF is 0-2g/L, the concentration of the aliphatic amine polyoxyethylene ether of nonionic is 0.05-0.35g/L, and the concentration of acid-base buffer agent is 1-5g/L.
Further, in step 1) described in the bath raio of dye liquor be 1:35, the volume ratio of alcohol organic solvent and water is 60%:40%, the concentration of CATION T is 0.3g/L, the concentration of dispersing agent C NF is 1g/L, the concentration of the aliphatic amine polyoxyethylene ether of nonionic is 0.25g/L, and the concentration of acid-base buffer agent is 2.5g/L.
Further, in step 3) in, the bath raio of described cleaning solution is 1:20-1:55, the volume ratio of alcohol organic solvent and water is 75-50%:25%-50%, the concentration of soap flakes is 1-5g/L, the concentration of sodium carbonate is 1-3g/L, in step 4) in wash temperature be 80-95 DEG C, wash time is 10-15min.
Further, in step 2) in, be warming up to 130-140 DEG C, dyeing time is 20-30min.
Further, described alcohol type organic is the one in ethanol or isopropyl alcohol.
Adopt technique scheme, beneficial effect of the present invention has:
1. use alcohol organic solvent as the solvent of dissolving dye and cleaning solution in the present invention, because the molecular proportion water of alcohol organic solvent is large, so when the vitrification point of temperature higher than cotton synthetic fibre, alcohol organic solvent can make the strand of cotton synthetic fibre movable thus increase intermolecular hole, such dyestuff is more to enter cotton synthetic fibre, one deck interfacial film can be formed on cotton synthetic fibre surface owing to adding the auxiliary agents such as dispersant simultaneously, the dye molecule of attachment be spread gradually, avoids the phenomenons such as the look flower of wink dye generation.
2. in the present invention the aliphatic amine polyoxyethylene ether of CATION T, nonionic and dispersing agent C NF with the use of; add CATION T and obviously can increase dyestuff to the dye-uptake of cotton synthetic fibre and degree of fixation; do not affect its staining simultaneously; the aliphatic amine polyoxyethylene ether of nonionic can reduce the staining of dyestuff to cotton synthetic fibre; but also can increase and decrease few dyestuff to the dye-uptake of cotton synthetic fibre and fixation simultaneously; improve the staining phenomenon produced owing to adding separately the cotton synthetic fibre of dispersant; and dyeing is simple; protection of the environment; cost is lower, is applicable to large-scale industrial production.
