ABSTRACT:
Modified, regenerated cellulosics having good receptivity to acid dyes are prepared by introducing a poly-2-alkyl-2-oxazoline, such as poly-2-ethyl-2-oxazoline, having a weight average molecular weight of at least about 10,000 into an aged, cellulose-xanthate solution and forming modified, regenerated cellulosics therefrom. These cellulosics exhibit rapid and quantitative acid-dye absorption and good dye fastness.
