Definitions

  • the invention relates to a process for the treatment of cellulosic molded articles, which are prepared from a solution of cellulose in an aqueous tertiary amine oxide, in particular fibers and structures containing these fibers, in which process the shaped bodies are brought into contact with a textile auxiliary in order to Give moldings improved properties.
  • shaped body includes sponges in particular.
  • the solvent used is a tertiary amine oxide, in particular N-methylmorpholine-N-oxide (NMMO).
  • NMMO N-methylmorpholine-N-oxide
  • the WO 99/19555 describes a process for treating solvent-spun fibers in which the fibers are contacted with 2,4-dichloro-6-hydroxy-1,3,5-triazine or with a salt thereof.
  • the fibers thus produced are characterized by a better resistance to fibrillation.
  • the WO 01/48025 describes cyclodextrins which are covalently bound to a polysaccharide by means of a crosslinking agent.
  • cellulosic molded articles prepared from a solution of the cellulose in an aqueous tertiary amine oxide can be treated with a textile auxiliary comprising a cyclodextrin and / or a cyclodextrin derivative to give products having improved properties.
  • the moldings are preferably fibers in never-dried state.
  • the fibers can be treated in a never-dried state in a post-treatment stage of a continuous processing plant.
  • cyclodextrins may include drugs that are then released, for example, over a longer period of time.
  • the treatment with the textile auxiliaries is preferably carried out in an alkaline medium.
  • the textile auxiliary additionally comprises a crosslinking agent.
  • a crosslinking agent particularly preference is given to using 2,4-dichloro-6-hydroxy-1,3,5-triazine or a salt thereof as crosslinking agent.
  • the textile auxiliary comprises 2-chloro-4-hydroxy-1,3,5-triazinyl-cyclodextrin (MCT-CD) or a salt thereof.
  • the invention also relates to a solvent-spun cellulosic fiber obtainable by the process according to the invention and to fiber structures which contain these fibers.
  • the fibers were mixed at a liquor ratio of 1:10 with a solution containing 20 g / l sodium salt of 2,4-dichloro-6-hydroxy-1,3,5-triazine, 16 g / l NaOH and 100 g / l of a cyclodextrin ( CAVAMAX W7, manufacturer Wacker-Chemie) for 5 minutes at room temperature impregnated.
  • the fibers were then squeezed to a moisture content of 100% -110% by means of a squeezer and heat treated for 5 minutes with saturated steam (100%) at 100 ° C, washed and dried.
  • the content of active cyclodextrin in the fibers thus produced was determined photometrically (552 nm) on the basis of the decolorization of a phenolphthalein solution and was 2.33% by weight.
  • the degree of fibrillation was determined by wet scrub resistance (test method according to WO 99/19555 ) of the individual fibers. According to this test method, a value of 210 revolutions results on average for the sample treated according to the invention. An untreated fiber, in comparison, exhibits a wet rub of only 40-60 turns.
  • Example 2 The procedure was as in Example 1, wherein the treatment solution 20 g / l sodium salt of 2,4-dichloro-6-hydroxy-1,3,5-triazine, 16 g / l NaOH, 30 g / l of soda and 50 g / l of a Cyclodextrins (CAVAMAX W7, manufacturer Fa. Wacker-Chemie) contained.
  • CAVAMAX W7 Cyclodextrins
  • the content of active cyclodextrin in the fibers thus obtained was 1.65 wt.%, The wet abrasion value was 470 revolutions.
  • Example 2 The procedure was as in Example 1, the treatment solution containing 30 g / l of sodium carbonate and 100 g / l of 2-chloro-4-hydroxy-1,3,5-triazinylcyclodextrin (MCT-CD; CAVASOL W7 MCT, manufacturer Wacker-Chemie). Chemistry).
  • the content of active MCT-CD in the fibers thus obtained was 1.89 wt%.
