Dyeing of cellulose warp yarns with coloured sizes - contg. Leuco vat dyes subsequently developed by actinic light

摘要

Warp yarns of cellulose or cellulocse contg. fibres are dyed at pH 3-8 with a thickened size soln. contg. leveo vat dyes, subsequent exposure in the wet state to actinic light, drying, weaving and making-up without post-treatment. Sizing and dyeing are achieved in a single simplified process.
