Definitions
- This invention relates to the production of artificial threads, filaments, bands, films or the like containing proteins. It is known to spin into threads alkaline spinning solutions containing casein or other proteins by employing spinning baths containing acid. The artificial threads made in this way have, however, little value as substitutes for textile fibres since they possess only very low strength.
- the present invention accordingly comprises a process for the production of artificial threads, 35 filaments, bands, films or the like containing proteins from solutions of alkali salts of protein by bringing the said solution into contact with an acid precipitating bath which process consists in incorporating in the precipitating bath a proportion of a substance which has a precipitating action on glue solutions and a tanning action on the freshly produced artificial product and thereafter subjecting the said artificial prodnot to hardening with formaldehyde or the like.
- the thread, filament, band, film or the like may be subjected to tension whiie still in the acid bath.
- the tanning substances added to the precipitating bath may consist of condensation products of aromatic and hydroaromatic sulfonic acids and aldehydes and include in particular the water soluble methylene compounds resultifig from the condensation of aromatic and hydroaromatic sulfonic acids or their hydroxy, amino In Germany August 4, 1936 or chlorine derivatives and the like with aldehydes for example formaldehyde.
- tanning substances which may be employed in the precipitating bath, the following specific compounds may be mentioned, di-
- the tanning substance may also consist of an aromatic sulphonic acid including the monoor polysulphonic acids of aromatic or hydroaromatic hydrocarbons or of monoor polysulphonic acids of oxygen-containing derivatives of aromatic or hydroaromatic hydrocarbons.
- the monoor polysulphonic acids may further be employed in the form of their compounds with aliphatic alcohols. There may also be employed sulphonic acids of aromatic or hydroaromatic monoor polyhydroxy compounds, of keto-compounds, or of carboxylic acids. Examples of the above substances are naphthalene-sulphonic acid, tetraline-sulphonic acid, toluene-isopropyl-sulphonic acid, phenol-sulphonic acid, cyclohexanone-sulphonic acid, benzoic-sulphonic acid and so forth. Such substances have a. different action in the precipitating bath from that of free aldehydes since they do not attack the amino groups of the protein. 1
- the spinning bath may also contain a soluble salt or a mixture of soluble salts and these salts may include for example the sulphates of sodium, am-
- the acid concentration of the precipitating bath may vary between wide limits and this conv centration may be controlled either by neutraliscarbo-hydrates such as glycerol, sugar and the like, or mineral or organic acids.
- the sulphonic acids of the monoor polyhydroxy compounds have the advantage of a higher solubility when salts are present-
- These added substances also possess the advantage that they are simple and cheap to manufacture, and even at lowconcentrations they have a tanning action which is even superior to that of the condensation products mentioned above.
- the freshly spun thread has an appreciabiy increased strength and the rate of drawing ofi may thus be increased.
- Threads, filaments, bands, films or like artificial products obtained in accordance with the present invention are firmer than those prepared in the normal precipitating baths sothat a higher .degree of stretching may be applied thereto, this stretching resulting in a more pronounced orientation of the micells and in the production of products possessing greater strength.
- Example I A 17.5% solution of sodium caseinate is spun into a spinning bath consisting of 20% zinc sulphate, 1% sulphuric acid and 5% of the neutralised condensation product obtained by the action of half a molecule of formaldehyde on one. molecule of cresyl sulphonic acid.
- the casein solution is spun with a total titre of 250 denier from a spinning nozzle having 0 holes each of a diameter of mu. After the thread has travelled through a distance of about 60 centimetres in the spinning bath a tension of for example 25 grams is allowed to act upon it and a considerable increase in strength is thereby obtained.
- a tension of for example 25 grams is allowed to act upon it and a considerable increase in strength is thereby obtained.
- the thread is subsequently hardened with a 10% solution of formaldehyde and is then washed and dried at a moderate temperature. Hardening may take place immediately after spinning or at a later stage.
- the product is flexible and has a strength which even exceeds that of sheeps wool.
- Casein obtained from skim milk is dissolved in 14% ammonia water to form a 16% casein solution.
- This solution is spun at 45 C. in a spinning bath containing 10% by weight of sodium sulphate, 10% by weight of zinc sulphate, 3% by weight of sulphuric acid and 3% by weight of cresol sulphonic acid.
- the initial tension which may be applied to the thread in the spinning process if the abovementioned sulphonic acid is employed in the spinning bath is greater than that which can be used if the sulphonic acid is not present. This increased tension results in an increased rate of spinning.
- a process for the production of proteincontaining artificial threads, filaments, bands and the like which comprises extruding a solution of an alkali salt of a protein into an acid precipitating bath containing at least one substance selected from the group consisting of aromatic and hydroaromatic acids and the condensation products of aromatic and hydroaromatic sulphonic acids with aldehydes, for exerting a glue precipitating action and for tanning the formed product, tensioning said product while in said bath and finally treating the product with a hardening agent.
