Method for dyeing materials from cellulose fibers with anionic dyes

专利摘要:
Compound for use in the dyeing of cellulosic fibers by anionic dyes, method of making such compound and method of dyeing involving the use of such compound. The compound has the general formula <IMAGE> wherein R1 and R2 are alkyls with 1-3 carbon atoms, R3 is alkylene with 1-2 carbon atoms, R4 is a hydrogen atom or an alkyl with 1-2 carbon atoms, and X is an anion of a strong inorganic ore organic acid. Such compound may be produced by a method in which 70 to 80 parts by weight of 35% hydrochloric acid are gradually added to 100 parts by weight of N,N-dimethylbenzylamine whereupon the temperature of the reaction compound is adapted to the value of 40 DEG to 80 DEG C. and 55 to 75 parts by weight of epichlorhydrin are gradually added, wherein the temperature of the resulting compound is kept between 60 DEG to 100 DEG C. over the course of 60 to 120 minutes since the last addition of epichlorhydrin.

The invention relates to a process for dyeing materials from cellulosic fibers with anionic dyes. The method expands the degree of utilization of these dyes and improves the degree of colouration. To improve the degree of coloration and to expand the use of some anionic dyes, mainly susantive and active, some epoxy ammonium compounds have been proposed and protected. From the works of Rupin Um. Pup In and count. Textilveredrung, 5, 1970, N 11, p. 829-8383 N- (2,3-ExipropylM, H, -trimethyl-ammonium chloride) is known. This compound reacts with hydroxyl cellulose groups with its epoxy group and forms a cellulose ether. The quaternary ammonium group then binds anionic dyes, resulting in increased strength dyeing and increasing the degree of dye utilization of the phone. The compound can react with cellulose before dyeing or during the dyeing process. The disadvantage of this method is that trimethylamine is released from this compound in an alkaline medium. giving an unpleasant odor, malodor, apparently, is the cause of this inhibit the spread of the dyeing process. Another means povyshakichim etc. NOSTA coloration mainly substantive dyes, NCH is a 2,3-epoxypropyl) -N-methylmorpholine chloride. Compared to the previous compound, it has almost no unpleasant odor, but is less effective. The solution to the problem of developing a drug with high activity that does not have an unpleasant odor is possible in several ways. One possible option is a compound in accordance with this invention, represented by the general formula: + 1 3 / D-G x CH2-SYa-CH2-1-B and he where I K alkyl with 1 to 3 carbon atoms ft is lkkylene 1-2 carbon atoms, a hydrogen atom or an alkyl with 1-2 carbon atoms; - anion of a strong mineral or organic acid. The compound is transferred in an alkaline medium to an epoxy-ammonium compound of the type SNg-CH-CH2-K 1, which can react with cellulose. According to the invention, the method of dyeing cellulosic fiber materials with anionic dyes using quaternary ammonium compounds is implied that the material is treated in an alkaline medium before dyeing or in the dyeing process, or after dyeing with a compound of general formula (). Compounds according to the invention can be synthesized from M; ,, M-dimethylbenzylamine, epichlorohydrin and hydrochloric acid, or from similar starting materials; Compounds are stable during long-term storage; no odor. They can be used for cationization of cellulose before dyeing, simultaneously with dyeing or after dyeing. Example 1. Cotton fabric after preliminary finishing is impregnated on a plus bath with a bath containing, g. 20 N- (2-hydroxy-3-chloropropyl) -Ubenzyl-I, M-Dimethylammonium chloride; 15 Pr my blue ff With,:. 15 sodium hydroxide. Spin 701, temperature 20 ° C, Tissue in a roll is kept at 20-25 C for 12 h, then washed with water at. The resulting color is blue, juicy and pka, it has good resistance to wet treatments. Example 2. Fabric from a mixture of б7% cotton and 33% viscose staple yarn after pre-finishing is impregnated on a semi-finished bath containing g. 25 N - (2-hydroxy-3-chloropropyl) -1-ethylenephenyl-M, M-dimethylammonium bromide, 25 sodium carbonate. Next, the fabric is squeezed to 80%, dried at 100 ° C, the color is fixed for 90 s at. This is followed by rinsing and 3 staining on a jigger with the dye Active blue W C.J.5, intensity of 3% staining. Dyeing is carried out in the absence of commonly used salt and alkali. The dyeing time is 60 minutes. Dyeing finish washing and soaps at boiling. The resulting color is highly resistant to wet treatments. The dye, when dyed, is almost completely selected from the bath. Example 3- Flax yarn with a cross package after pre-finishing is treated in a dyeing apparatus with a bath module 1: A of composition, 15 forms of M- (2-oxy-3 chloropropyl) -N-besyl-N, M-dimethyl-amino, 10 Sodium hydroxide After washing, the yarn is dyed with Acid Green No. C.Z. 12. dye with a color intensity of 1% at) for 0 min. Dyeing finish washing at. The resulting color has a very good resistance to wet treatments. Note k. A cotton yarn fabric dyed in the usual way on a jigger. Preamble 67 If C-.E, with color intensity 2, after washing the treatment 84 is woven on the jigger of the bath composition, Ch: 5 2-chloro-3-hydroxypropyl, H- benzyl, I, H-dimethylammonium chloride, 5 sodium hydroxide. Processing time 30 min at kffC. Then the fabric is washed until neutral. The resulting color is highly resistant to washing at 95 ° C. , Example 5. Viscose staple-fiber fabric after printing with active dyes: Active red (D C..45 Active blue NT C; J. 13 Active brown If C, E.2 and fixing the dye zalary-: soak impregnated on the bathtub of the composition, chl 25 2-chloro-3-hydroxypropyl-M-benzyl, M, M-dimethylammo "bromide; 15 sodium hydroxide. The fabric in the roll is kept for 12 hours at 20-25 C, then washed in succession by treatment in three baths with water temperature, then in two baths with Bopja temperature and in one bath with cold water. riznano invention of the examination by the Office for invention Chehos / yuvatskoy socialist republic.
