Definitions
- This invention relates to an improved process for producing artificial fibres such as filaments, threads and the like by spinning protein solutions, particularly casein solutions.
- Protein solutions coming into consideration for spinning fibres are prepared by dissolving proteins suitable or rendered suitable to this efiect, for instance casein or other animal or vegetable proteins, such as fish proteins and soya protein, in diluted alkaline solution. Moreover inorganic or organic substances may be added to these solutions, which substances influence the spinning process or the products obtained in some way or other. Such a solution is then spun in an acid spinning bath, consisting as generally known of solutions of strong acids, salts and if desired organic substances. Also spinning baths have been proposed, consisting of mixtures of alcohol and organic acids. Since these latter baths are however impractical and uneconomic the first mentioned baths are generally preferred.
- the spinning bath may according to my invention also consist of a solution of organic salts with or without inorganic salts, to which only such an amount of inorganic acid and if desired organic acid is added that the pH value of the spinning bath is more than 2 and preferably above 2.7 or even above 3.0.
- the spinning baths according to the invention may contain organic substances substantially not influencing the pH value, such as for instance alcohol, glycerol, glucose, urea and the like.
- An example of a spinning bath for use according to my invention is an aqueous solution con- Shrinkage Maxl- Mink of the s inningbatb Tern 8552?; 11 $831111? as we e:

- a process for the production of protein products of low shrinkage characteristics comprising spinning a solution of protein material in dilute alkali into an aqueous spinning bath containing 5% of lactic acid, 5% of sodium lactate and 15% of magnesium sulphate in solution therein.
