Abstract (en)
The prodn. of aminated regenerated cellulose fibres (I) comprises making a soln. of cellulose and a protein with a mol. wt. of more than 50000 or a natural prod. contg. such a protein (II) and spinning fibres from this soln. Also claimed are (i) textile fibre material consisting of (I); and (ii) a process for dyeing and printing such textiles with anionic dyes, using a dye soln. contg. no additional electrolyte salts, at a pH of 4-6 for direct and acid dyes and 6-8.5 for reactive dyes.
