• This invention relates to a process of producing artificial fibers, films, foils, ribbons and the like materials capable of being dyed by acid wool dyestufis.
• a further object 01' the invention is the provision of artificial fibers which can be dyed together 25 with wool and in thesame dyeing bath in 'uniform tints.
• Still another object is the provision of artificial fibers, threads and the like textile materials, which consist of cellulose hydrate, cellulose 30 acetate or a similar filmor fiber-forming polymer' and which contain dispersed therein an addition of a basic artificial resin.
• Suitable organic bases are, for instance, the alkyleneimines, such as ethylene-, propyleneand butylene-imines, N-propyl-ethyleneimine and 50 N-benzylethyleneimine.
• Flu'thermore aliphatic and aromatic amines such as methylamine, stearylamine andaniline may be employed. 5
• Suitable protein substances are casein, albu- 55 men, gelatin, and the like materials.
• arylisoand arylisothiocyanates there may be employed mainly the phenyland naphthylis'ocyanates as well as the phenyland naphthylisothiocyanates, benzylisocylenate, and related compounds :
• arylisoand arylisothiocyanates there may be employed mainly the phenyland naphthylis'ocyanates as well as the phenyland naphthylisothiocyanates, benzylisocylenate, and related compounds :
• the resinous compositions may be added to the spinning 'solutions'either in the form of the reaction mixture or they may be isolated beforehand and added to the spinning solutions as powdery substances.
• the synthetic resins may be added to viscose solutions, to cuprammonium spinning solutions or to cellulose acetate solutions.
• the finished fibers have exactly thesame properties from the point of view of the colorist as wool.
• the fastness to light and washing of dyeings thereon with acid wool dyestuils equals that of wool.
• Example 1 500 grams of casein are added in successive small portions while stirring to liters of an aqueous solution of per cent strength of ethyleneimine. This mixture is allowed to stand for 24 hours, during which period the casein enters into reaction with the ethyleneirnine and becomes quickly dissolved. The solution is cooled and 3 kilos of phenylisocyanate are added thereto drop by drop while strongly stirring. The white emulsion first produced gradually solidifies to a fine powder which is insoluble in dilute acids and alkalies. The product contains 22 per cent of nitrogen. It may be added to the spinning solution in the form of an emul- 56 sion produced by making it into a paste with warm cyclohexanol. The thread obtained on spinning is very similar to wool in respect of being dyed.
• Example 2.1 kilo of casein is stirred cautiously in small portions into 5 liters of an aqueous solution of 30 per cent strength of ethyleneimine, and the whole is allowed to stand overnight.
• the mixture is diluted with 2 liters of trichlorethylene and there are added gradually by drops while cooling'and stirring 5 kilos of phenylisocyanate.
• the white emulsion thus obtained is suspended in 2 liters of cyclohexanol and the whole is heated-for 1 hour at C. 300 grams of this emulsion are added to 10 liters of viscose (cellulose content 7.9 per cent, alkali content 6.3 per cent), and the mixture is stirred until the animalizing agent-has been uniformly distributed in the viscose.
• the viscose thus obtained, after filtration and subjection to a vacuum, is spun.
• the animalized fiber has a good afilnity for acid wool dyestufls.
• the product is an almost transparent highly viscous solution which may be directly emulsified with viscose.
• the spun fibers have a character similar to that or wool.
• Example 4 300 grams of casein are added in small portionswhile stirring to 1 liter of ethyleneimine of 30 per cent strength. The solution is allowed to stand overnight and then filtered. To the filtrate 300 cc. of phenylisothiocyanate are added drop by drop. When this addition is complete, the whole is heated for 2 hours at 70 C. From the product thus obtained there is prepared an emulsion in cyclohexanol and this is added to viscose.
• Example 5 --500 grams of casein are stirred into 3.3 liters of a solution oi ethyleneimine or 15 per cent strength. After a short heating to 40 C. the whole is left standing for 24 hours at room temperature. 'Ihe casein is then completely dissolved. To this mixture of casein and ethyleneimine there are gradually added while stirring 1 liter of phenylisocyanate by drops. The temperature of the reaction mixture must not rise above 40 C. The white reaction product is carefully filtered and well washed with hot water. The condensation product is insoluble in dilute acids and alkalies. It is soluble, for instance, in pyridine, aniline alnd meta-toluidine. ,If this solution is added to a spinning solution fibers of wool-like character are obtained.
• Artificial textile materials capable of being dyed by acid wool dyestuffs in the same manner as wool, comprising a polymer useful in forming an artificial textile material incapable per se of being dyed by acid dyes, and finely distributed therein the product of a joint polymerization of the reaction product or an alkyleneimine and a protein, with a compound selected from the group consisting of arylisocyanates and arylisothiocyanates.
