Aromatic primary amino group was introduced into cellulose by curing with 4-amino-phenyl-g-sulfatoethylsul(one. These free amino groups, even in very low concentration, altered the chemical properties of cellulose. The animalized cotton fabric absorbed anionic dye and reacted with rective dye and glutaraldehyde. Thus the dyeing properties of it were investigated and the possibility of application to the crease-resistant finish was discussed.
