                    Fat diamine polyoxyethylene ether application in printing and dyeing processing performance study

                      Fat diamine polyoxyethylene ether application in printing and dyeing processing performance study Fatty amine polyoxyethylene ether was made up by senior fatty amine and epoxy ethane addition reaction, the periods of low number of polyoxyethylene base, reflect certain properties of cationic surfactants, as the growth of the polyoxyethylene chains, cationic weaken gradually, reflect the nature of the nonionic surfactant, make its have washing, leveling, permeability, prevent the generalization and dispersed and other functions, is widely used in textile, printing and dyeing, food, medicine, cosmetics and other fields, has wide application prospect.This paper chooses the five kinds of fat two amine polyoxyethylene ether (ADAEO10 ADAEO15 ADAEO30, ADAEO45 and ADAEO15 / PO6), fat 2 amine polyoxyethylene ether was studied and the interaction between different acid dyes, discusses the two fat amine polyoxyethylene ether and its distribution of fertilizer application in the dyeing of silk and nylon acid dyes, and in the prevention of acid dyes on silk dyeing printing after washing with soaping color effect.The results show that the fat 2 amine polyoxyethylene ether and there is certain effect between different acid dyes.The maximum absorption wavelength is mainly manifested in the change of the displacement and the maximum absorbance, this kind of change varies with the dye.In dye must be as the fat diamine polyoxyethylene ether EO, with the increase of percentage of the interaction of auxiliaries and dyes decrease gradually.With ADAEO10 effect the most significant with acid dyes.Fat diamine polyoxyethylene ether join can effectively reduce the dyeing rate of acid dyes on silk, with two fat amine polyoxyethylene ether EO into reducing, retarding effect increases, dyed fabric uneven degree of decline, with ADAEO10 and ADAEO15 levelling effect is better.With the increase of concentration of additives, retarding effect is obviously enhanced, the general dosage is 0.5 g/L can achieve the ideal effect.Agent concentration is too high, will bring down the acid dye dyeing rate in the final.Choose ADAEO10, ADAEO15 and peregal O - 25 according to different proportion distribution of levelling agent A and B to silk and nylon have good leveling effect.In the acid dyes on silk dyeing, leveling agent than levelling agent B effect is better;In the acid dye on the polyamide fiber dyed, both effects are better.Fat 2 amine polyoxyethylene ether join can effectively prevent the contamination of acid dyes and silk fabrics, with the increase of dosage of additives, soaping stained color proof is enhanced.Which ADAEO30 and ADAEO45 stained color effect is better.With ADAEO30, ADAEO45, ADAEO15 / PO6, PVP, peregal O - 25 and chelating dispersant according to the different proportion of the compound with 4 kinds of touch in real silk dyeing printing after washing agent has good anti fouling effect, which the formula 1 of real silk fabrics with the color effect is best.
