ABSTRACT:
Anionically dyeable smooth-dry crosslinked cellulose is produced by modifying cellulose-containing material with the combination of a hydroxyalkylamine or a hydroxyalkyl quaternary ammonium salt, a methylolamide crosslinking agent and one or more reactively inert glycol ether swelling agents. The reaction is typically catalyzed with salts such as zinc nitrate or magnesium chloride used either alone or in conjunction with citric acid. Types of usable anionic dyes include acid, direct, and reactive dyes. The cellulose-containing material may be in the form of fibers, threads, linters, roving, fabrics, yarns, slivers and paper.
