Abstract
Anionically dyeable smooth-dry crosslinked cellulosic materials are produced by treatment of methylolamide crosslinked cellulosic materials with an alkali swelling agent such as sodium hydroxide prior to dyeing. Attainable color strength is dependent upon both the concentration and the contact time of the alkali swelling agent with the cellulosic material. 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.
