Definitions

  • the invention relates to the use and use of antimicrobial polymers for the production of antimicrobial nonwovens such as textile composites and papers.
  • Mucus layers often form, which cause microbial populations to rise extremely, which have a lasting impact on the quality of water, beverages and food, and can even lead to product spoilage and consumer health damage.
  • Bacteria must be kept away from all areas of life where hygiene is important. This affects textiles for direct body contact, especially for the genital area and for nursing and elderly care. In addition, bacteria must be kept away from furniture and device surfaces in care stations, in particular in the area of intensive care and the care of small children, in hospitals, in particular in rooms for medical interventions and in isolation stations for critical infections and in toilets.
  • the copolymer produced with aminomethacrylates is only a matrix or carrier substance for added microbicidal active substances which can diffuse or migrate from the carrier substance.
  • Polymers of this type lose their effect more or less quickly when the necessary “minimum inhibitory concentration” (MD) is no longer achieved.
  • a large number of contact microbicidal polymers are known from the following patent applications: DE 100 24 270, DE 100 22 406, PCT / EP00 / 06501, DE 100 14 726, DE 100 08 177, PCT / EP00 / 06812, PCT / EP00 / 06487 , PCT / EP00 / 06506, PCT / EP00 / 02813, PCT / EP00 / 02819, PCT / EP00 / 02818, PCT / EP00 / 02780, PCT / EP00 / 02781, PCT / EP00 / 02783, PCT / EP00 / 02782, PCT / EP00 / 02799, PCT / EP00 / 02798, PCT / EP00 / 00545, PCT / EP00 / 00544.
  • These polymers do not contain any low molecular weight components; the antimicrobial properties are due to the contact of bacteria with the surface.
  • textile composites and papers in which flat structures are produced directly from filaments and fibers, are particularly susceptible to microbiological attacks due to their generally porous structure combined with a large surface area. This can e.g. in the presence of moisture, lead to the complete decomposition of the substrate, which has a devastating effect on traditional antiquarian books and writings, and has catastrophic effects on the protection of historic monuments.
  • the present invention therefore relates to antimicrobial nonwovens containing antimicrobial polymers.
  • nonwoven materials are referred to below as nonwovens, fiber materials, textile composite materials, random nonwovens or nonwovens with preferred orientation being encompassed.
  • the nonwovens according to the invention are preferably constructed entirely from antimicrobial polymers; it is also possible for the nonwovens to contain non-antimicrobial substrates such as paper, textile composites, polymer fibers, metal fibers, glass wool, vegetable fibers.
  • the nonwovens according to the invention can be produced by in the course of the production of nonwovens, for. B. of textile composites and papers of the fiber mixture antimicrobial polymers, finished nonwovens with antimicrobial polymers or refined nonwovens from polymers by surface grafting of monomers or monomer mixtures from which antimicrobial polymers are produced.
  • the antimicrobial nonwovens according to the invention can consist entirely of antimicrobial polymers. These polymers can e.g. B. in the form of fibers and then processed into a tangled nonwoven.
  • the substrate can already be present as a nonwoven or the nonwoven intermediate, e.g. B. fibers or threads can be coated.
  • the product resulting from all of the described procedures is a textile composite or paper with an antimicrobial finish without the addition of low molecular weight biocides.
  • the products manufactured in this way can be further processed into all products that were previously based on unmodified textile composites and papers.
  • These products can e.g. are filters, disposable tissues, disposable handkerchiefs, hygiene articles, papers, packaging cardboard or the like.
  • the generally known production and processing methods for textile composites and papers can be used, as described in the relevant literature, e.g. in Hans-Georg Elias, Macromolecules, Volume 2 Technology, Hüthig & Wepf Verlag, 5th edition, pp. 547 to 557.
  • antimicrobial cellulose papers can be obtained, for example, by adding antimicrobial polymers during the processing of the aqueous suspension of the cellulose fibers.
  • radical centers are generated on the surface of the substrates to be refined, which can serve as starting points for the grafting process.
  • the generation of corresponding radical centers is e.g. by lighting, corona, plasma, UV radiation or initiators, e.g. in U.S. Patents 5,967,714 and 6,096,800.
  • antimicrobial nonwovens that combine the mechanical and processing properties required for the tasks as well as the biochemical inhibitory effect on microbial growth in an almost ideal way. Since the antimicrobial polymer is fixed in the matrix of the nonwovens and consequently no low-molecular components are released into the environment, such systems can also be used in sensitive areas, e.g. air purification or direct physical contact, e.g. when used as a paper handkerchief, can be used without the toxicologically questionable transfer of biocides from the product.
  • Nitrogen- and phosphorus-functionalized monomers are preferably used for the production of the antimicrobial polymers.
  • Monomers functionalized in this way are also suitable for the described refinement by means of surface grafting.
  • these polymers are prepared from at least one of the following monomers: 2-tert-butylaminoethyl methacrylate, 2-diethylaminoethyl methacrylate, 2-diethylaminomethyl methacrylate, 2-tert-butylaminoethyl acrylate,

  • Acrylic acid methyl ester acrylic acid ethyl ester, acrylic acid butyl ester, acrylic acid tert-butyl ester, tert. -Butylaminoethylester.
  • the proportion of the antimicrobial polymers in the nonwovens can be 0.01 to 70% by weight, preferably 0.1 to 40% by weight, particularly preferably 0.1 to 20% by weight.
  • all materials used for the production of nonwovens can be used as substrates, in particular glass wool, metal fibers, paper, silk, rayon, cotton, wool, flax, ramie, aramid, polyether sulfones, polyamides, polyesters, polyacrylic derivatives, polyethylene, polypropylene, PTFE, Polymethacrylates, polysulfones, polyacrylonitriles, cellulose, cellulose, cellulose acetate or other cellulose derivatives.
