The presence of a covalent bond between the active centers of the dye and the fiber nucleophilic groups provides a bright and strong colors . Significant disadvantage of the use of reactive dyes is the need to use large amounts of neutral electrolytes in periodic staining methods . Total consumption of sodium chloride (the most commonly used electrolyte ) estimated several million tons per year. Only a small portion of salt lingers in waste water treatment plants , the remainder is discharged into the environment , almost not change . Thus water pollution by chlorides - urgent problem requiring urgent solutions . The most radical and economically feasible way to reduce the inorganic salts in wastewater dyeing and finishing enterprises is neutral electrolyte exception of dyeing technology through the use of cationic drugs. The developed technology of dyeing of cotton textiles with reactive dyes using cationic polymers allows the exclusion of neutral electrolyte and reduce the length of dyeing process by 1.5 times to get intense, uniform and resistant to physical - chemical influences coloring.
