Abstract
The invention relates to a reactive dye and especially relates to a reactive dye low-salt dyeing assistant and belongs to the technical field of dye chemical engineering. A cationic additive is added into a dye liquor, so that the cationic additive loosely bonds with the dye thus dye electrical properties are reduced, or the cationic additive is absorbed by fibers at first thus fiber interface electrical properties are reduced and electrostatic repulsion between the fibers and the dye is reduced and a dyeing rate and a fixation rate are improved. Therefore, the reactive dye low-salt dyeing assistant realizes low-salt dyeing. Betaine has no damage on a human body and the environment, and most betaine can be metabolized in a human body so that an environmental load caused by nitrogen produced in betaine decomposition is tiny.
Description
Technical field
The present invention relates to a kind of REACTIVE DYES, be specifically related to a kind of REACTIVE DYES low salt dyeing auxiliary agent, belong to the dye chemical industry technical field.
Background technology
REACTIVE DYES with bright in colour, chromatogram is complete, application is easy, with low cost, fastness is good and famous.The particularly development of cellulose fibre in recent years, REACTIVE DYES have become the most important dye of cellulose fiber textile dyeing.But the distinct issues of REACTIVE DYES are that degree of exhaustion and degree of fixation are low, the utilization rate of dyestuff is not high, must add a large amount of inorganic salts (sodium chloride or sodium sulphate) for dye-uptake and the degree of fixation that improves REACTIVE DYES in the traditional dyeing of cellulose fibre.But consequent dyeing waste water causes serious environmental pollution.The discharge of wastewater of high salinity has directly changed the water quality in rivers and lakes, has destroyed ecological environment, is secondly waste salt resource, has increased cost.The most frequently used modifying agent can be with fiber with covalent bonds in recent years, namely introduce in amine salt or quaternary ammonium salt can with fiber in the epoxy radicals of hydroxyl reaction, with permanent cationic, dyeability is more stable through the cellulose fibre of this modification.Come modification as the compound with triethanolamine, or come modification with the hydrochloride of chloroethyl second two ammoniums, generate DEAE, this fiber is very strong to the reactivity of REACTIVE DYES.Due to tertiary amine groups, fixation speed is accelerated greatly, reactive dyeing there is catalytic action, can strengthen the fixation reaction.The reagent such as epoxy amine or quaternary ammonium cation is little molecular cation reagent, good penetrability, being beneficial to level dyeing dyes thoroughly, but consumption is large, and a lot of cationic reagents itself are unfavorable to environment, such as some amine substances are very large in occurring in nature toxicity, eyes, skin, respiratory tract etc. there are spread effect, operator healthy brought serious hidden danger.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of REACTIVE DYES low salt dyeing auxiliary agent is provided, add Cationic aid in dye liquor, itself and dyestuff are formed loose in conjunction with reducing the electrical or first by fibers adsorption of dyestuff, reduce fiber interface electrical, reduce the electrostatic repulsion between fiber and dyestuff, improve its dye-uptake and degree of fixation, realize low salt dyeing.Contain a cation radical and an anion base on betaine, cation radical can the sulfonic group formation ionic bond on dyestuff be combined, reduce the charge repulsion of dyestuff and fiber, dyestuff is increased the substantivity of fiber, thereby the consumption of the salt in dyeing is greatly reduced, realize the low salt dyeing of REACTIVE DYES.Simultaneously, betaine is to human body and environmentally friendly, and even most of betaine can be by metabolism in human body, and the nitrogen that produces during decomposition is extremely small to carrying capacity of environment.
The present invention realizes with following technical scheme: a kind of REACTIVE DYES low salt dyeing auxiliary agent, and it is characterized in that: described dyeing assistant comprises betaine and bi-quaternary ammonium salt; The chemical name of described betaine is the 1-carboxy-N, N, and N-trimethyl second lactone, molecular formula is (CH3) 3N+CH2COO-, with amino acid similarity, belongs to the quaternary amine alkaloids on chemical constitution; Described bi-quaternary ammonium salt contains two cation radicals.
Described betaine outward appearance is mobility, little brown crystalline powder, and 293 ℃ of fusing points, very easily water-soluble, be soluble in methyl alcohol, be dissolved in ethanol, be insoluble in ether, through the decomposition reaction of dense potassium hydroxide solution, can generate trimethylamine.
Advantage of the present invention is: add Cationic aid in dye liquor, itself and dyestuff are formed loose in conjunction with reducing the electrical of dyestuff or first by fibers adsorption, reducing fiber interface electrical, reduce the electrostatic repulsion between fiber and dyestuff, improve its dye-uptake and degree of fixation, realize low salt dyeing.Simultaneously, betaine is to human body and environmentally friendly, and even most of betaine can be by metabolism in human body, and the nitrogen that produces during decomposition is extremely small to carrying capacity of environment.
