METHOD OF TREATING WOOL MATERIAL WITH HYDROLYTIC ENZYME PREPARATION IN DYEING PROCESS

FIELD: textile industry. SUBSTANCE: wool material is dyed on boiling after preliminary treatment at 20 to 60 C with 0.5-1.0% (based on the weight of wool material) of aqueous solution of hydrolytic enzyme preparation with pH 7.0-8.0 possessing keratinase, protease, and amylase activities, the treatm...

Zusammenfassung:	FIELD: textile industry. SUBSTANCE: wool material is dyed on boiling after preliminary treatment at 20 to 60 C with 0.5-1.0% (based on the weight of wool material) of aqueous solution of hydrolytic enzyme preparation with pH 7.0-8.0 possessing keratinase, protease, and amylase activities, the treatment and dyeing being carried out in the same vat. EFFECT: increased resistance of coloration performed with acid dyes to dry friction, accelerated dyeing process due to extended choice of dyes, and strengthened intensity of coloration resistant to washing, distilled water, organic solvents, and ironing. 1 dwg, 7 tbl, 22 ex
