METHOD OF WOOLEN FABRICS PREPARATION FOR COLORING BY PRINTING Russian patent published in 1994 - IPC

FIELD: textile industry. SUBSTANCE: for preparation of woolen fabrics for coloring fabric is desized in aqueous solution of enzymic preparation amylosubtilysine from Bac. subtilis following by washing with water. Then fabric is treated at low-temperature plasma of glow discharge at frequency of current discharge 8-22 kHz and current density 0.5-1.5 mА/cm² for 5-20 s. Properties: capillarity of kerchief cloth with density 100 ± 5 g/m² is 65-80 mm/h, shrinkage interweaving is 2.1-2.2%, spreadability of printing dye at the band width 1 mm is 0.1-0.2 mm. EFFECT: improved method of woolen fabrics preparation. 1 tbl
