Definitions
- the invention relates to a method for producing protein shaped bodies from globular proteins according to the NMMO method and protein shaped bodies from globular proteins according to the MMO method.
- Globular proteins in the sense of
- protein moldings mean protein-containing moldings made from globular proteins.
- the first protein fiber was manufactured by A. Millar from gelatin (Vandura) in 1894, casein fibers from casein dissolved in glacial acetic acid were protected in GB 6 700 and US 625 345.
- F. Todtenhaupt found a much cheaper and easier-to-use solvent for casein in sodium hydroxide solution and coagulated the threads in a precipitation bath containing sulfuric acid and Glauber's salt, to which formaldehyde was added to stabilize the fibers (DE 170 051; DE 178 985; DE 183 317; DE 203 820).
- deformation products from mixtures of a casein solution and a cellulose xanthate solution can also be produced by the wet spinning process, and mineralized casein fibers by adding sodium or. Potassium silicate solution or a solution of alkali-soluble metal salts, such as zinc or aluminum compounds (GB 483 731; US 2 548 357).
- US Pat. No. 2,211,246 describes the use of dilute ammonia solution instead of dilute sodium hydroxide solution as a solvent.
- a method is known by which proteins are dissolved in dichloroacetic acid or trichloroacetic acid and in pure water or in methanol,
- Ethanol or aqueous ethanol can be coagulated (GB 684 506).
- the protein shaped bodies have to be hardened after the coagulation in order to fix the stretch-oriented polypeptide chains via cross-links.
- suitable aldehydes and dialdehydes as well as, for example, aluminum sulfate, formamide and dimethylolurea are suitable as hardeners.
- various methods for additional stabilization of the fibers are described in the literature. This can be done by acetylation (Ind. Engng. Chem. 36, 1171; Textile Res. J. 18), by formaldehyde treatment (Textile Res. J. 20, 95), by treatment with silicon halides (Ind. Engng. Chem. 36, 1171; Textile Res. J.
- N-methylmorpholine-N-oxide is also presented as a possible solvent for proteins.
- the subject of the patent is a solution of a natural or synthetic polymeric or monomeric component with a weight fraction of up to 70% in one of the solvents N-methylmorpholine-N-oxide, N-methylpiperidine-N-oxide, N-methylpyrrolidine-N-oxide or N-methyl-azacycloheptane-N-oxide and a process for the preparation of the aforementioned solution.
- the solvents are used in anhydrous form and the production of special moldings and special features for process design are not presented.
- DE 198 41 649 describes a process for the preparation of concentrated solutions of fibrillar proteins in NMMO monohydrate and its product-oriented processing presented.
- the globular proteins that occur in nature in large numbers and are often easily obtainable are excluded.
- the object of the invention is to provide a method according to which protein-containing molded articles can be produced in significantly fewer process steps and in a more environmentally friendly manner than previously.
- the object is achieved in this process in that a suspension of aqueous NMMO and globular proteins is converted into a spinning solution, this spinning solution is extruded through a molding tool and through an air gap into a precipitation bath, the molded body is then washed free of solvents and over with an aqueous liquid known crosslinking reactions is cured. Additional stabilization using known methods is possible.
- Moldings used equipment can be processed extremely environmentally friendly to protein moldings.
- a globular protein which is known to be crosslinked by means of known crosslinking reactions, for example by aldehydes and dialdehydes and, for example, also aluminum sulfate, forma id, dimethylolurea et al. is already pre-crosslinked, in which case the hardening / crosslinking of the shaped bodies after extrusion can then optionally be omitted.
- the crosslinking (s) expediently take place in the presence of Lewis acids, which serve as a catalyst for the crosslinking.
- the crosslinking (s) are expediently carried out at temperatures between 0 and 160 ° C. leads.
- the reactive groups for the crosslinking (s) are not only the aminoex groups and any acid amide groups, but also the imino groups of the peptide bond and the oxy groups of the serine.
- crosslinking through sulfur bridges or using benzoquinone is possible.
- a targeted pre-crosslinking of the protein significantly reduces the solubility in water and / or saline solution without significantly influencing the solubility in NMMO.
- the proteins due to their reactive groups, are able to stabilize the solvent against thermal decomposition, measurable, for example, by less discoloration of the extrusion solution compared to solutions of cellulose, for example.
- decomposition products of the solvent such as formaldehyde, react with the reactive groups and are thus trapped, so that they are no longer available for subsequent decomposition reactions.
- a polysaccharide is added to the suspension and / or the extrusion solution to modify the properties of the molded article to be produced.
- one or more global proteins are used as the protein and one or more polysaccharides and / or polysaccharide derivatives, which consist of hexoses with glycosidic 1,4- and 1,6-linkage or at least, are used as the polysaccharide are partially made up of uronic acid (s), preferably cellulose.
- uronic acid preferably cellulose
- water-insoluble or water-soluble homopolysaccharides and / or homopolysaccharide derivatives can be used as polysaccharide, which are built up from uniform basic units with different linking possibilities, as well as heteropolysaccharides, which in addition to uniform basic chain building blocks also have different building blocks, preferably bound as side chains.
- homopolysaccharides are starches, pullulan and hyaluronic acid
- heteropolysaccharides are pectin, algin, carrageenan, xanthan, carubin and guarane
- homopolysaccharide derivatives are chitosan, carboxyethylchitosan, carboxymethyl cellulose or cellulose acetate.
- the possibly pre-crosslinked protein and the polysaccharide are expediently activated before the spinning solution is prepared. This can be done by swelling in water, in aqueous NMMO, in liquid ammonia and / or by means of a suitable enzyme system.
- the proteins can be combined with synthetic polymers soluble in NMMO monohydrate, e.g. Dissolve poly (N-vinylpyrrolidone), polyvinyl alcohol, or polyethylene oxide.
- Spinning solutions prepared in this way can be processed according to the invention by the known wet or dry / wet spinning processes in an environmentally friendly manner and in a few process steps to form a wide variety of shaped articles, such as fibers, filaments and foils.
- other diverse product-oriented processing methods are possible, such as microfibers, fibrids and nonwovens produced by shear coagulation. These products in their entirety can in turn be used in a variety of ways.

- This residue-free spinning solution was extruded through a nozzle as filaments through an air gap into an aqueous precipitation bath (spinning temperature: 80 ° C; hole diameter: 90 ⁇ m; number of nozzle holes: 150; air gap: 15 mm). The filaments were then washed with dist. H 2 0 washed solvent-free and cut into fibers (40 mm). These fibers were post-cured in a 0.5% glutaraldehyde solution with the addition of MgCl 2 at 25 ° C. and then dried at 60 ° C. in a rocking cabinet.

In addition, 25 g (dry) ground sulfite pulp (DP 760) are added to the suspension. 0.5 g of propyl gallate was added as a stabilizer. This suspension is converted into a spinning solution in a jacket-heated kneading apparatus under a vacuum of 30 mbar at a temperature of 90 ° C. by distilling off 140 g of H 2 O. The homogeneity of the spinning solution was checked by light microscopy, which was given 15 minutes after the distillation had ended.
