Dyeing of cellulose-containing textiles in glycol and glycol ether solvents

摘要

The dyeing of cotton in glycol and glycol ether solvents containing direct or sulfur dyes is disclosed. Prior to dyeing, the fabric is treated with an aqueous solution to swell the fibers. When the pretreated cotton is dyed in solvent containing 0.25% to 2% potassium thiocyanate it results in improved color saturation. The instant invention is extremely effective for either cotton or cotton/polyester blends.
