METHOD FOR LIQUID TREATMENT OF WOOL MATERIALS UPON DYEING PROCESS Russian patent published in 1997 - IPC

FIELD: textile industry, in particular, washing upon fulling of dyed thin-cloth fabrics. SUBSTANCE: method involves fulling fabric in fulling solution containing surfactant; washing out for 30 min with further one-stage washing out including low, average, high rate water treatment. Surfactant with concentration of 0.4-0.6 g/l during washing is the mixture of anion-active and nonionogenic surfactants used in the ratio of 4:1. Such ratio produces significant synergism expressed in higher washing effect. Optimum concentration of surfactant allows surfactant consumption to be reduced. EFFECT: increased quality of ready material, simplified sewage cleaning process, reduced consumption of water and surfactant and reduced souring. 2 cl, 2 tbl
