Aminated cellulosic synthetic fibers

An aminated cellulosic synthetic fiber, prepared by a process comprising the step of:

• adding an amine-substituted saccharide to a viscose or an alkali cellulose and spinning fibers by a viscose spinning process, or by adding said amine-substituted saccharide to a cellulose solution and spinning fibers from said solution,
• wherein the amine-substituted saccharides are selected from the group consisting of
• polymers of olefinically unsaturated amines with saccharides and with cellulose components;
• or saccharides or cellulose components substituted with amines of the formula (1a) or (1b) ##STR10## where Y is an ester group;
• A and N together with 1 or 2 alkylene groups of 1 to 4 carbon atoms form the radical of a heterocylic ring wherein
• A is an oxygen atom or a group of the formula (a), (b), or (c) ##STR11## where R is selected from the group consisting of a hydrogen atom;
• an amino group;
• an alkyl group of 1 to 6 carbon atoms which is optionally substituted by 1 or 2 substitutents selected from the group consisting of amino, sulfo, hydroxyl, sulfato, phosphato and carboxyl;
• and an alkyl group of 3 to 8 carbon atoms which is interrupted by 1 or 2 groups of the formulae --O--, --NH-- or a combination thereof or is optionally substituted by an amino, sulfo, hydroxyl, sulfato or carboxyl group,
• R.sup.1 is hydrogen, methyl or ethyl,
• R.sup.2 is hydrogen, methyl or ethyl, and
• Z.sup.(-) is an anion;
• B is selected from the group consisting of an amino group of the formula H.sub.2 N--, an amino, ammonium group of the formula (d) and ammonium group of the formula (e) ##STR12## where R.sup.1, R.sup.2 and Z.sup.(-) are each as defined above,
• R.sup.3 is methyl or ethyl, and
• R.sup.4 is hydrogen, methyl or ethyl;
• p is 1 or 2;
• alkylene is selected from the group consisting of a straight-chain alkylene radical of 2 to 6 carbon atoms, which are optionally substituted by 1 or 2 hydroxyl groups, a branched alkylene radical of 2 to 6 carbon atoms which are optionally substituted by 1 or 2 hydroxyl groups, a straight-chain alkylene radical of 3 to 8 carbon atoms which is interrupted by 1 or 2 groups of the formulae --O-- and --NH-- and a combination thereof;
• and a branched alkylene radical of 3 to 8 carbon atoms which is interrupted by 1 or 2 groups of the formulae --O--, --NH-- or a combination thereof;
• alk is selected from the group consisting of a straight-chain alkylene radical of 2 to 6 carbon atoms, a branched alkylene radical of 2 to 6 carbon atoms, a straight chain alkylene radical of 3 to 8 carbon atoms which is interrupted by 1 or 2 groups of the formulae --O--, --NH-- or a combination of --O-- and --NH--, or a branched alkylene radical of 3 to 8 carbon atoms which is interrupted by 1 or 2 groups of the formulae --O--, --NH-- or a combination of --O-- and --NH--;
• m is 1 or 2;
• n is from 1 to 4;
• and
• the amino, hydroxyl and ester groups can be attached to a primary, secondary or tertiary carbon atom of the alkylene radical;
• the saccharides being monosaccharides, oligosaccharides, polysaccharides, thermally or mechanically treated saccharides, oxidatively, hydrolytically, or enzymatically degraded polysaccharides, oxidized hydrolytically or enzymatically degraded polysaccharides, chemically modified mono-, oligo-, or polysaccharides, or mixtures thereof.
