Reactions of ethleneimine with various aldehydes and acid chlorides were investigated. The reaction products retain the reactive aziridinyl groups in their molecules, and can react with cellulose. Diaziridinyl phenyl methane obtained by the reaction of ethyleneimine with benzaldehyde and N-stearoyl ethyleneimine obtained by the reaction of ethyleneimine with stearoyl chloride were investigated to use as the finishing agents of viscose rayon fibers. It was found that the physical properties of the fibers treated with these agents in solution are hardly affected by the treatments, but the dyeability is considerably improved. The fibers are dyeable almost alike wool. It is considered that only the surface of the fibers are modified chemically in the treatment with the finishing agents. Viscose rayon fibers which are mixed-spun with small amounts of diaziridinyl, phenyl methane were produced, but the physical properties of the rayon fibers were not found to be so good. Compounds produced by the reactions of ethyleneimine with furfural, glyoxal and glutaryl dialdehyde were so unstable that they could not be used in the finishing of the cellulose fibers.
