Description
Известен способ крашени и печати хлопчатобумажного волокна основанием голубого фталоцианинового ЧЗМ с применением в качестве растворител смеси формамида, этиленгликол , глицерина и триэтаноламина. Однако , вследствие сложности окрашивани и дефицитности составных частей растворител применение основани голубого фталоцианинового ЧЗМ затруднено.There is a known method of dyeing and printing cotton fiber with a blue phthalocyanine base of CHSM using a mixture of formamide, ethylene glycol, glycerin and triethanolamine as a solvent. However, due to the complexity of staining and the lack of components of the solvent, the use of a blue phthalocyanine FZM base is difficult.
С целью улучшени крашени трудно покрашиваемых тканей, упрощени процесса крашени и расширени ассортимента растворителей предложен способ, в котором в качестве растворител примен ют мочевину.In order to improve the dyeing of difficult-to-be dyed fabrics, simplify the dyeing process and expand the range of solvents, a method has been proposed in which urea is used as a solvent.
Печатна краска или раствор дл крашени , при условии введени в него мочевины, представл ет собой устойчивую смесь, так как в водной среде в этих услови х и при комнатной температуре никаких химических процессов не происходит.Printing ink or solution for dyeing, provided that urea is introduced into it, is a stable mixture, since no chemical processes occur in an aqueous medium under these conditions and at room temperature.
При применении мочевины растворение, а затем взаимодействие составл ющих красител происход т лишь при повышении температуры . При ЭТОМ исключаютс побочные процессы , происход щие при применении смеси растворителей, в результате чего полученный пигмент голубой фталоцианиновой свободен ОТ побочных продуктов, придающих гр зный цвет соединению, образующемус на первой стадии после сушки ткани и вызревани .When urea is used, the dissolution and then the interaction of the constituents of the dye occurs only with an increase in temperature. This process eliminates the side processes that occur when using a mixture of solvents, as a result of which the blue phthalocyanine pigment obtained is free of side products, which impart a dirty color to the compound formed in the first stage after drying the fabric and aging.
В результате пр моточности реакции, волервых , достигаетс значительное уменьшениеAs a result of the reaction flow, wolves, a significant decrease is achieved.
интенсивности кислованн ткани после вызревани , благодар чему сокращаетс врем кисловани и обеспечиваетс возможность замены минеральной кислоты бисульфитными соединени ми, или слабощелочными обработками; во-вторых, уменьшаетс концентраци основани фталоцианинового голубого ЧЗМ примерно вдвое до 20 г/кг, (вместо 40 г/кг) при получении одинаковой насыщенности окраски. Это вление объ сн етс также полиморфизмом фталоцианинового пигмента и тем, что при использовании мочевины в качестве промотора происходит образование пигмента в кристаллической форме, обладающей высокой цветностью.the intensity of acidification of tissue after aging, thereby reducing the acidification time and providing the possibility of replacing mineral acid with bisulfite compounds, or weakly alkaline treatments; secondly, the base concentration of phthalocyanine blue FZM is reduced by about half to 20 g / kg (instead of 40 g / kg) while obtaining the same color saturation. This phenomenon is also explained by the phthalocyanine pigment polymorphism and the fact that when urea is used as a promoter, pigment is formed in a crystalline form with high chromaticity.
При применении в качестве оастволител мочевины рекомендуетс готовить в заводских услови х дисперсию основани , мочевины и воды по типу изготовлиие паст кубовых красителей дл печати.When used as an urea solubilizer, it is recommended to prepare under factory conditions a dispersion of the base, urea, and water by the type of manufacture of bottoms dyes for printing.
Примерный состав пасты следующий (в г):The approximate composition of the paste is as follows (in g):

Пасту можно приготовл ть на дисковой краскотерке, в коллоидной мельнице или другими известными способами, позвол ющимц получать тонкие дисперсии.The paste can be prepared on a disk paint mill, in a colloid mill or by other known methods, allowing the preparation of fine dispersions.
