Definitions

• viscose fibers are essentially the same as those of cotton fibers.
• alkaline dispensing agents and electrolytes are required for dyeing cellulosic natural or regenerated fibers in order to achieve satisfactory fixing results with reactive dyes.
• regenerated fibers based on cellulose will therefore be of increasing importance. They have previously been converted into highly dye-affine, i.e. Salt and alkali-free dyeable modifications have been transferred.
• the chemical behavior of fibers modified in this way is similar to that of animal fibers, such as wool or silk, and can be dyed under neutral conditions with anionic dyes, without further salt or alkali additives.
• DE-A-1 469 062 also deals with "aminalized fibers".
• the additives are aminoethyl and diethylaminoethyl celluloses in high concentration, coloring is done exclusively with acid dyes.
• the object of the present invention was to provide modified viscose fibers in order to dye textiles from such fibers with low salt and alkali with anionic dyes and to obtain a fabric with a soft feel.
• a viscose fiber can be produced which, surprisingly, is significantly more affinity when dyed with anionic dyes and which has the desired properties compared to conventional viscose fibers, for example due to a soft feel clearly differentiates.
• the present invention relates to a process for the production of regenerated cellulose regenerated fibers, characterized in that a solution of cellulose and a protein with a molecular weight of greater than 50,000 or a natural product containing such a protein is prepared and fibers are spun from this solution.
• the procedure is such that a) cellulose and a protein with a molecular weight greater than 50,000 or a natural product which contains such a protein are mixed and the mixture is subjected to alkaline digestion and the resulting alkaline digested mixture is reacted with carbon disulphide or b) a protein with a molecular weight greater than 50,000 or a natural product which contains such a protein, dissolves in sodium hydroxide solution and adds it to a spinning viscose, and transfers the viscose spinning solution obtained according to a) or b) into an acidic spinning bath and spins it into fibers.
• reaction with carbon disulphide expediently takes place at temperatures of 15 to 30 ° C.
• Subsequent spinning in an acidic spin bath gives the aminated cellulose fibers according to the invention.

• the cellulose and the protein are dissolved in a suitable organic solvent, for example N-methylmorpholine-N-oxide / water, reacted with one another and spun directly from the solution into fibers.
• fibers After spinning in an acidic spinning bath, fibers are obtained which can be dyed according to the invention using low-electrolyte or completely electrolyte-free and alkali-free or alkali-free dyeing liquors (including printing pastes and ink-jet liquids).
• Low-electrolyte dyeing liquors are understood to mean those with an electrolyte content of less than 15 g / l and low-alkali dyeing liquors to those with a pH of at most 8.5.

• the dyeing of the modified viscose according to the invention takes place between pH 4 and pH 8.5, depending on the type of dye.
• salt contents of 0.01 to 0.5% by weight, based on the dyeing liquor, are normally present. Without the amination of the cellulose fibers according to the invention, however, this salt content would be too low by a factor of 50 to 1000 for a successful dyeing process.
• the incorporation of the alkaline digested or dissolved protein into the viscose spinning mass is advantageously carried out without emulsifiers.
• the protein is added in an amount of 1 to 20% by weight, preferably 1 to 12% by weight, based on the cellulose content of the dope, before the precipitation and shaping.
• the viscose is deformed using customary methods, such as with spinnerets, a subsequent precipitation bath and, if necessary, further post-treatment baths.
• the fibers obtained by the described methods can be dyed after processing into fabrics and knitted fabrics, using a wide variety of processes, such as exhaust, padding and modern printing processes - and this includes ink-jet processes - without the use of salt or alkali.

• the dyes used to dye the modified cellulose are generally anionic in nature.
• the fiber-reactive textile dyes are those which can react with hydroxyl groups, for example of cellulose, or amino and thiol groups, for example of wool and silk, of synthetic polymers, such as polyamides, or also the celluloses aminated according to the invention, and one covalent bond are particularly suitable.
• the sulfatoethylsulfonyl, vinylsulfonyl, chlorotriazinyl and fluorotriazinyl group and combinations of these reactive groups may be mentioned in particular as fiber-reactive components on the textile dyes.
