Description

A kind of colouring method based on cotton fabric by utilizing reactive dye cation modifier
Technical field
It is more particularly to a kind of to be based on cotton fabric by utilizing reactive dye cation modifier the invention belongs to dye chemical industry technical field Colouring method.
Background technology
Reactive dye have the features such as vividness is good, easy to use, and color fastness is good, thus are widely used in fiber dye Color, it can form covalent bond in dyeing course with cellulose fibre, and color fastness is high.But reactive dye contaminate for anionic Material, and cotton fiber is also negatively charged in dye bath, therefore larger electrostatic repulsion between the two be present, and then have impact on dyeability Can, the problem of dye-uptake and low degree of fixation be present in reactive dye, therefore need in traditional dyeing process to add a large amount of inorganic salts with The electrostatic repulsion between dyestuff and cellulose is reduced, improves dyestuff dye-uptake and degree of fixation.However, this technique causes to environment Serious pollution, adds the intractability of dyeing waste-water, therefore reduces the salt alkali number during reactive dye use as printing and dyeing Worker endeavours one of hot issue solved.
Cotton fiber cationization is a kind of method of more effective lifting dyeability, and cellulose fibre is through modification Afterwards, cationic compound is anchored on cellulose fibre, while electrostatic repulsion is reduced, increases electrostatic attraction, can be significantly The dye-uptake of dyestuff is improved, and then saves dyestuff.
Cationization or aminated cellulose fibre can be obtained to the rate of adsorption and its stainability of reactive dye and significantly changed It is kind.In fact, early in 1962, there have been import cation group in cellulose molecular structure to improve cotton fiber dyeing The patent introduction of performance.Cation base, amino etc. are introduced in fiber macromolecular can be obviously improved the stainability of fiber, commonly use Cationic reagent in addition to epoxies nitrogen-containing compound, also have following several：One chloro-s-triazine type quarternary ammonium salt compound, nitrogen Azetidine cationic compound, NMA and cationic acrylamide base co-polymer, hydroxyalkyl ammonium salt compounds with And biomass cationic reagent.Han Jing is changed by synthesis of quaternary ammonium cation-type water-thinned polyurethane modifying agent to bafta Property, reach low salt dyeing effect；Sang-Hoon Lim etc. have synthesized a kind of cationization chitosan derivatives and bafta have been carried out It is modified, reach the salt-free effect of less salt；The alkali-free cation modifier for the group containing multi-active base that Luo Yanhui, Han Lijuan etc. are independently synthesized STGX-2 is modified to bafta under the conditions of alkali-free, and less salt effect has been reached after dyeing.
The agent of cotton fiber cation modifying can be divided into monomer class and polymerization species.Monomer class presence substantivity is poor, dosage is big, The shortcomings of unstable；It is larger, direct strong to polymerize species relative molecular mass, dosage is less to can reach dyeing effect well Fruit, but the difficult control of partial cation type polymer modifiers relative molecular mass, the fiber after processing exist level dyeing, through-dyeing compared with Difference, the problems such as coloured light is uncontrollable, it is not widely applied so far.Early stage research is glycidyl quaternary ammonium salt, but this kind of sun from The shortcomings of small molecular mass, direct poor, long processing period, big dosage be present in sub- reagent.
The invention provides a kind of new colouring method based on cotton fabric by utilizing reactive dye cation modifier, by with paddy The pre-treating technology that propylhomoserin sodium or Sodium phenylalaninate are dyed to bafta, can be before salt, base amount and dyeing temperature be reduced Put, realize effectively improving for dyeability, both reduced the environmental protection pressure of wastewater treatment, save opening for scale wastewater treatment Branch, excellent dyeability is obtained again.
The content of the invention
It is above-mentioned in the prior art because reactive dye are anionic dyes in order to overcome, and cotton fiber also band in dye bath Negative electrical charge, larger electrostatic repulsion between the two be present, have impact on dyeability, so in order to carry when being directed to reactive dyeing High dye-uptake and degree of fixation, a large amount of inorganic salts need to be added and promote wastewater treatment load weight caused by dye, processing cost height, ecological environment The shortcomings that heavy damage and deficiency, primary and foremost purpose of the invention are to provide a kind of cation-modified based on cotton fabric by utilizing reactive dye The colouring method of agent.
After the inventive method carries out modification using cotton fiber cation modifier to cotton fiber, cationic compound is solid On cotton fiber so that cotton fiber surface electrical behavior reduces, and repulsion reduces between dyestuff, while increases electrostatic attraction, can be significantly Degree improves the dye-uptake of dyestuff, and then saves dyestuff, and while bafta properties are not changed, effectively reduces saline and alkaline Dosage, dyeing temperature is effectively reduced, realize environmental protection dyeing.
The purpose of the present invention is realized by following proposal：
A kind of colouring method based on cotton fabric by utilizing reactive dye cation modifier, comprises the following steps：
(1) modification：Cotton fiber is added in the glutamate aqueous solution or phenylalanine saline solution, heating treatment, Take out, washing, obtain modified cotton fiber；
(2) dyeing is handled：Modified cotton fiber is dyed according to common process, wherein, reactive dye contain in dyeing liquor Measure as 1~2wt%, 5~10g/L of sodium carbonate, 23~30g/L of sodium chloride, dyeing condition be dyeing 40 at 50~70 DEG C~ 60min；
(3) cotton fiber is post-processed according to common process after dyeing is handled, and obtains dyeing processes.
Glutamate aqueous solution Glutamic Acid salinity described in step (1) is 2.0~8.0g/L, preferably 2.0g/L.
