Description
Technical Field
The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a one-bath quick bleaching agent for printing and dyeing, and a preparation method and application thereof.
Background
In the traditional textile printing and dyeing process, the traditional process of the polyester/cotton fabric needs to be pretreated firstly, the cotton is bleached under the conditions of alkalinity and hydrogen peroxide, and then the polyester is dyed by using disperse dyes under the acidic condition after being washed. In the process, a large amount of wastewater is generated, the burden is increased for sewage treatment, the environment is polluted, a large amount of steam is generated, and the energy consumption, the time and the labor cost are high. Therefore, it is very important to find a quick bleaching agent which can bleach cotton when the disperse dye is used for dyeing terylene and does not influence the depth and color of the terylene fiber dyed by the disperse dye.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides the one-bath quick bleaching agent for printing and dyeing, and the preparation method and the application thereof.
In order to achieve the purpose, the invention adopts the following technical scheme:
a one-bath quick bleaching agent for printing and dyeing is characterized in that: the quick bleaching agent comprises a separating agent I, a separating agent II and a separating agent III, wherein the mass ratio of the separating agent I to the separating agent II to the separating agent III is 1:1: 2; the agent I comprises a fiber amorphous region channel expanding agent accounting for 88% of the total mass of the agent I, and the balance of water; the fiber amorphous area channel expanding agent comprises the following components in percentage by mass: 30-40% of benzyl benzoate, 10-15% of diethylene glycol phthalate or dipropylene glycol phthalate, 20-25% of dibutyl maleate, 15-25% of fatty alcohol-polyoxyethylene ether and 5-10% of ethylene glycol butyl ether; the dispersant II comprises a dispersant accounting for 9-12% of the total mass of the dispersant II and the balance of water; the component III comprises 25-30% of dye antioxidant by mass and the balance of water.
The fatty alcohol-polyoxyethylene ether is isomeric tridecanol polyoxyethylene ether or isomeric tridecanol polyoxyethylene ether.
The dispersant is C12～18H25-37O(CH2CH2O)15～20H or povidone K30.
The dye is used for preventingThe oxidant is HO (C)4H2O5M2)nNa。
The fiber amorphous area channel expanding agent comprises the following components in percentage by mass: 38% of benzyl benzoate, 14% of diethylene glycol phthalate, 23% of dibutyl maleate, 15% of isomeric tridecanol polyoxyethylene ether and 10% of ethylene glycol butyl ether; the dispersing agent is povidone K30 accounting for 10% of the total mass of the dispersing agent II; the dye antioxidant is HO (C) accounting for 27 percent of the total mass of the component III4H2O5M2)nNa。
Because the polyester fiber has a compact structure, high crystallinity and difficult dyeing, the invention adopts benzyl benzoate as a carrier of disperse dye, has solubilization effect on the disperse dye, and ensures that the dye amount dissolved in the carrier adsorption layer on the surface of the fiber is far higher than the dye amount dissolved in a dye bath, thereby increasing the concentration difference of the dye inside and outside the fiber, accelerating the diffusion of the dye to the interior of the polyester fiber, and the benzyl benzoate has plasticization effect on the polyester fiber, so that the Tg of the polyester fiber can be reduced, the macromolecule chain segment in an amorphous region of the polyester fiber can move at a relatively low temperature, the microgaps in the fiber are increased, and the holes are increased, thereby increasing the dyeing rate of the disperse dye by the polyester fiber. When the mass fraction of the benzyl benzoate is too high, the benzyl benzoate has an inhibiting effect on the combination between disperse dye molecules and fibers, and the dye uptake and the breaking strength of the fibers are easily reduced, so that the benzyl benzoate accounts for 30-40% of the total mass of the channel extender in the amorphous region of the fibers.
The diethylene glycol phthalate or the dipropylene glycol phthalate can generate a synergistic interaction effect with other components such as benzyl benzoate, fatty alcohol-polyoxyethylene ether and the like, and further expand the amorphous area of the polyester fiber, so that the disperse dye can enter the fiber more easily, and meanwhile, the disperse dye entering the fiber is easy to diffuse and migrate from the inside to the outside of the fiber.
The fatty alcohol-polyoxyethylene ether is a nonionic surfactant, has stable chemical property, strong acid resistance, strong alkali resistance and high temperature resistance, is not easy to be oxidized, has less foam, can prevent the aggregation of disperse dye particles in dyeing, can be used as a levelling agent, delays the speed of dyeing fibers by the dye, and avoids the phenomena of uneven depth and color spots. The isomeric tridecanol polyoxyethylene ether is used as one of fatty alcohol polyoxyethylene ether, is a green and environment-friendly nonionic surfactant, and is the best substitute for substituted nonyl phenol surfactants.
Ethylene glycol monobutyl ether is a safe and environment-friendly solvent, can effectively promote the dissolution of other components in the dispersing agent I, and can also effectively promote the dispersion of disperse dyes.
C12～18H25-37O(CH2CH2O)15～20H and polyvidone K30 are used as nonionic chelating dispersant, and have effects of resisting deposition and protecting color.
HO(C4H2O5M2) nNa sodium polyepoxysuccinate is a green antisludging disperser, and can reduce Ca in water during bleaching and dyeing2+、Mg2+、Cu2+、Fe2+The influence of the metal ions on the product quality and the decomposition of hydrogen peroxide also have a protective effect, so that the whiteness can be obviously improved, and the yellow spot phenomenon of the fabric can be eliminated.
A preparation method of a one-bath quick bleaching agent for printing and dyeing comprises the following steps:
(a) heating and stirring benzyl benzoate, diethylene glycol phthalate or dipropylene glycol phthalate and dibutyl maleate uniformly at 85-100 ℃ in proportion, cooling to 35-50 ℃, adding fatty alcohol-polyoxyethylene ether and ethylene glycol monobutyl ether in batches in proportion at the temperature, and stirring uniformly to obtain a partitioning agent I;
(b) uniformly stirring and mixing a dispersing agent and water at 35 ℃ in proportion to obtain a dispersing agent II;
(c) at normal temperature, the dye antioxidant and water are stirred and mixed uniformly according to a proportion to obtain the dispersant III.
The quick bleaching agent can be used for a polyester-cotton fabric printing and dyeing process.
The polyester-cotton fabric printing and dyeing process comprises the following steps: putting the polyester-cotton fabric into a dyeing machine, injecting water into the dyeing machine according to a bath ratio of 1:10-15, adding a separating agent I, a separating agent II and a separating agent III, heating to 40 ℃, running for 10-15 minutes, then adding glacial acetic acid, hydrogen peroxide and disperse dye, heating to 85-130 ℃ at the speed of 1-2 ℃/min, dyeing for 25-40 minutes, then cooling to 60 ℃, draining, reducing, cleaning, washing with water, dyeing cotton by using active dye, soaping, and fixing color to obtain the polyester-cotton dyeing fabric.
The dosage of the partitioning agent I is 1g/L, the dosage of the partitioning agent II is 1g/L, the dosage of the partitioning agent III is 2g/L, the dosage of the glacial acetic acid is 1.5-2g/L, the dosage of the hydrogen peroxide is 4.5-5.5g/L, and the dosage of the disperse dye is 0.25-0.5% of the weight of the polyester-cotton fabric.
The invention has the beneficial effects that: through reasonable proportioning of the components of the quick bleaching agent, the synergistic effect among the components is fully exerted, cotton fibers can be bleached during dyeing, the depth and the color of polyester fibers dyed by disperse dyes are not influenced, and the quick bleaching agent is applied to a polyester cotton dyeing process, so that the pretreatment step of the traditional dyeing process can be omitted, a large amount of water, steam and electricity consumption is saved, energy conservation and emission reduction are realized, the production efficiency can be effectively improved, and the production cost is reduced.
