Abstract

The invention relates to the field of dyeing and finishing production, in particular, to the method of dyeing and anti-salable finishing of wool fiber. The invention makes it possible to reduce the wool salinity from 8 to 4-5 points, to increase its physical and mechanical properties (breaking strength by 11.4%, breaking load by 12.6%, crimpiness by 9%) and resistance to alkaline environments by 22, 5% due to the fact that the dyeing is carried out in the presence of the drug sintegal U and 2-3% by weight of the glycerin fiber. 1 tab.

Description

The invention relates to the chemical technology of fibrous materials, in particular to the method of dyeing and the anti-depletion of the wool fiber finish.

The purpose of the invention is to reduce the habits of wool fiber, increasing its physical and mechanical properties and resistance to alkaline media.

In the proposed method, the drug sintegal U based on the condensation product of higher fatty acids with ethylene oxide and glycerin is used.

The use of glycerol in dyeing changes the state of the scaly layer of wool fiber by adsorbing glycerol only to its surface layer.

All components except the dye are introduced into the bath heated to 30-40dC, wool fibers are loaded and processed for 10 minutes. Thereafter, a dye solution is added to the bath and dyeing is carried out for 10 minutes. Then, over a period of 30 minutes, the bath is heated to and dyeing at this temperature for 20 minutes. Then for 30 minutes the bath is heated to 85 ° C and dyeing is carried out.

Then, 25% ammonia is added to pH 7-7.5 and the wool fiber is treated for 10-15 minutes, after a period of time the solution is drained, and the fiber is washed with water in the presence of CI1K (0.5% by weight of fiber ) at 35–40 ° C for 10–15 min. G asgvor is drained and the fiber is washed with a cold coda.
