Definitions

  • MPN fibers polymer nano-fibers
  • MPM fibers milk protein micro and superficrofibers
  • Electrospinning processes for producing protein fibers are described, for example, in patents EP 09156540.8 and EP 08162122.9. Centrifuge spinning processes suitable for the production of nanofibers are disclosed, for example, in EP 624 665 A, EP0813622 and EP 1 088 918 A. In these centrifugal spinning processes, the polymer-containing solution or dispersion is placed in a rotating container and discharged by centrifugal forces from the container in the form of fibers.
  • German Patent 09170024.5 (BASF) describes a process for the production of coated protein fibers by means of a centrifugal spinning technique, wherein it is essential to the invention that the fibers are contacted during or after their preparation with a 2-cyanoacrylic acid ester.
  • 2-cyanoacrylic acid ester These are thin-bodied or deliberately thickened esters of cyanoacrylic acid, which come in 1 K form as monomers in the trade and react by polymerization reaction in the joint gap to the actual adhesive polymer.
  • nanofibers are to allow the penetration of the skin and the absorption of drugs and thus toxicological substances are absorbed by the skin.
  • various measures are described in the literature.
  • One possible method is to influence the properties of the polymers by crosslinking reactions.
  • the invention is based on the object of avoiding the abovementioned disadvantages and of imparting a necessary water or moisture resistance to polymer fiber materials, preferably from renewable raw materials (especially protein-based) and preferably without the addition of acrylates and fossil raw materials.
  • the invention is intended in particular to reduce the processing time and the use of chemicals, wherein the MPN and MPM fibers are preferably and largely to be produced from renewable or biodegradable raw materials. At the same time, water and energy consumption are to be reduced and productivity increased.
  • the present invention is directed to MPN and MPM fibers made by a continuous or discontinuous process from a composition comprising destructured milk proteins, biodegradable thermoplastic polymers and plasticizers.
  • At least one protein obtained from milk or a protein produced by bacteria is optionally plasticized together with a plasticizer at temperatures between room temperature and 140 ° C under mechanical stress.
  • the invention is based on the finding that the milk proteins and in particular casein and its derivatives are plasticized and processed in this way. It is preferably provided that the plasticizing takes place at temperatures preferably up to 140 ° C.
  • the protein is intensively mixed or kneaded together with a plasticizer and subjected to mechanical stress.
  • the required plasticizing temperature is significantly reduced by the plasticizer.
  • the milk protein is preferably casein or lactalbumin or soy protein.
  • the milk-derived protein can be produced in situ by precipitation from milk.
  • the milk in mixture with rennet, other suitable enzymes or acid introduced directly as a flocculated mixture in the process or the pressed flocculated protein can be used wet.
  • a separately previously obtained, optionally treated pure or mixed protein, ie a Protein fraction can be used from milk, eg dried as a powder.
  • the protein fraction can also be produced by ultrafiltration or by cell cultures.
  • the milk proteins for example, with additional salts such as sodium, and potassium can be modified in further processing steps, so that a casein arises.
  • the milk protein used according to the invention can be mixed with other proteins in a proportion of preferably up to 70% by weight, based on the milk protein.
  • other albumins such as ovalbumin and vegetable proteins, in particular lupine protein, soybean or wheat proteins, in particular gluten come into question.
  • the mixture of solvent and protein is heated, usually under pressure conditions and shear, to accelerate the crosslinking process.
  • Chemical or enzymatic agents can also be used to destructivate and crosslink the milk proteins, oxidize or derivatize, etherify, saponify, and esterify.
  • milk proteins are destructured by dissolving the milk proteins in water. The milk proteins are completely destructed if there are no clumps affecting the fiber spinning process.
  • a plasticizer can be used in the present invention to make the milk proteins more destructive and to allow the milk proteins to flow, ie to produce thermoplastic milk proteins.
  • the same plasticizer or other plasticizer can be used to increase melt processability, or two separate plasticizers are used.
  • the plasticizers can also improve the flexibility of the final products, believed to be due to the lowering of the glass transition temperature of the composition by the plasticizer.
  • the plasticizers are substantially compatible with the polymeric components of the present invention so that the plasticizers can effectively modify the properties of the composition.
  • the term "substantially compatible" means that the plasticizer, when heated to a temperature above the softening and / or melting temperature of the composition, is capable of forming a substantially homogeneous mixture with milk proteins.
  • the plasticizer is preferably water used in a proportion of between 20 and 80% based on the weight of the protein, preferably in a proportion of about 40 to 50% by weight of the protein content.

  • hydroxylic plasticizer Important influencing factors are the affinity for the proteins, the amount of protein and the molecular weight. Glycerine and sugar alcohols are among the most important plasticizers. Parts by weight of plasticizers are e.g. 5% - 55%, but may also be in the range of 2% - 75%. Any of alcohols, polyols, esters and polyesters may be used in proportions by weight, preferably up to 30% in the polymer blend.
