Abstract
The invention discloses a cellulose fiber modifier, which belongs to the technical field of textile dyeing. The cellulose fiber modifier is characterized in that the cellulose fiber modifier is essentially prepared by the following raw materials in mass portion: 50 to 70 portions of epoxy chloropropane, 20 to 30 portions of epoxy chloropropane, and 5 to 15 portions of dicyandiamide. The product is used for modifying cellulose fiber to ensure that the cellulose fiber is cationized, and then can be dyed by reactive dyes under salt-free and alkali-free conditions. The cellulose fiber modifier has the advantages that the cellulose fiber modifier has good color fastness, is salt-free and alkali-free in residual liquid, is favorable to the sewage disposal, reduces the difficulty of sewage disposal, contributes to the environmental protection, reduces the cost, and improves the quality of products at the same time.
Description
Technical field
The invention belongs to the textile dyeing technical field, particularly a kind of cellulose fiber modifier and synthetic, this modifier belongs to the polyepichlorohydrin amine compounds.
Background technology
Cellulose fibre is electronegative in water, and the dyestuff that is used for cellulose dyeing mostly is anionic dye, and both repel mutually, and dye-uptake is not high, the dyeing waste-water contaminated environment.In order to improve the adhesion of cellulose fibre to anionic dye, people have done number of research projects, change dye structure, use to substitute salt, to cellulose fibre modification poststaining etc., when they have all alleviated cellulose dyeing to a certain extent to the pollution of environment.For example, with the aminate of Hydrin to the COTTON FABRIC preliminary treatment after with the direct dyes and the reactive dyeing of 1%, 2% (owf), dyeing waste-water is almost colourless.The polyepichlorohydrin amine thing mostly is high molecular polymer, and molecular mass is 1380～2100, and during to the cellulose fibre modification, modifier is difficult to enter cellulose fibre inside, only in surface modification, during dyeing, forms ring and dyes.Therefore, the molecular mass of modifier is one of key factor that influences the modified fabric dyeing uniformity.
During dyeing, under the effect of water and auxiliary agent, it is 2～3nm that the space of the noncrystalline domain of cellulose fibre increases, and dyestuff mainly enters the noncrystalline domain after expanded.In surface modification, the particle diameter of modifier should be less than 2nm for fear of only.The development modifier that molecular mass is low, nitrogen content is moderate, cellulose fibre has higher tinctorial yield to anionic dye after keeping modification, improves its level-dyeing property simultaneously.
" development of low molecular mass, cellulose fiber modifier polyepichlorohydrin amine thing that nitrogen content is moderate " (Zheng Jiancheng, 2005 the 12nd phases of Yu Yinan " printing and dyeing assistant ") disclose the synthetic of a kind of low molecular mass, cellulose fiber modifier polyepichlorohydrin amine thing that nitrogen content is moderate, its concrete grammar is 300ml CCl

2Make catalyst, the 92.5g epoxychloropropane slowly drips in 3.5h, and reaction finishes back standing demix, separatory.Get the Hydrin behind the above-mentioned separatory, be respectively by pure dimethylamine and Hydrin mass ratio and carried out amination in 1: 1,2: 1,3: 1.Drip dimethylamine agueous solution 1h, continuation reaction 8h prior to 95 ℃.The disclosed content of the document is quoted at this as prior art.
This method reaction is complicated, and the reaction time is longer.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of synthetic method of cellulose fiber modifier is provided, the cellulose fiber modifier that the present invention synthesizes is the polyepichlorohydrin amine thing.
The following technical scheme of the concrete employing of the present invention, that is:
A kind of cellulose fiber modifier is characterized in that, is made by the raw material of following parts by weight in essence:
50～70 parts of epoxychloropropane
20～30 parts of diethylenetriamines
5～15 parts of dicyandiamides.
The method for making of described cellulose fiber modifier comprises the steps:
In reactor, diethylenetriamine and dicyandiamide raw material are mixed with the aqueous solution of 40% concentration by weight the ratio of 2:1, drip epoxychloropropane not being higher than under 60 ℃ the condition of normal pressure then, dropwise the back less than 60 ℃ of following insulation reaction 3-4 hours, promptly get cellulose fiber modifier of the present invention.
Beneficial effect of the present invention is:
1) to the cotton fiber chemical modification, improve the dyeability of cotton fiber to REACTIVE DYES, and can reach the dyeing draining clean compliance with environmental protection requirements;
2) this polyepichlorohydrin amine thing is soluble in water, has good heat endurance.Molecular weight is lower, easy permeable fiber when preliminary treatment is cotton, and nitrogen content is moderate, leaves more chloromethyl reactive group.Under alkali condition, cellulose ion is a nucleopilic reagent, and the chloromethyl in this polymer can react with nucleopilic reagent, and the end group of polymer also can be converted into epoxy radicals and fibrin reaction under the alkali condition, and the reactivity of cellulose and modifier is strong.Can reduce the negative ξDian Wei of cellulose fibre during the modification poststaining significantly, dye under salt-free neutrallty condition with REACTIVE DYES, the dyestuff dye uptake is improved greatly, pigment significantly reduces in the dyeing residual liquid.
3) COLOR FASTNESS is good, and salt-free alkali-free helps sewage disposal in the raffinate.Reduce the sewage disposal difficulty, help environmental protection.Reduce cost simultaneously, improve the quality of products.
1) composition of raw materials: prepare burden according to following table
Unit: Kg
| Embodiment 1 | Embodiment 2 | Embodiment 3 | |
| Epoxychloropropane | 70 | 60 | 50 |
| Diethylenetriamine | 20 | 25 | 30 |
| Dicyandiamide | 5 | 12.5 | 15 |
2) preparation method: batching is selected from each prescription of embodiment 1-3
At first in reactor, diethylenetriamine and dicyandiamide raw material are mixed with in proportion the aqueous solution of 40% concentration, slowly drip epoxychloropropane and, can finish reaction from head tank not being higher than under 60 ℃ the condition of normal pressure then at 60 ℃ of following insulation reaction 3-4 hours.
The usage ratio 2:1 of diethylenetriamine and dicyandiamide is the ratio that the applicant preferably uses among the present invention, and in fact, as embodiments of the invention, the ratio of diethylenetriamine and dicyandiamide also is to reach the object of the invention, and just effect is poor slightly.
Product of the present invention is used for that cellulose fibre is carried out modification makes it cationization, can dye with REACTIVE DYES under salt-free alkali-free condition then, is characterized in that COLOR FASTNESS is good, and salt-free alkali-free helps sewage disposal in the raffinate.Reduce the sewage disposal difficulty, help environmental protection.Reduce cost simultaneously, improve the quality of products.
Compared with prior art, its unique distinction is: salt-free, non-alkali dyeing, environmental protection, COLOR FASTNESS is good, cost is low, quality is good.
