Definitions

  • the invention relates to a ner process for the treatment of cellulosic molded articles which are produced from a solution of the cellulose in an aqueous tertiary amine oxide, in particular fibers and structures which contain these fibers, in which ner process the foam articles are brought into contact with a textile auxiliary in order to To give moldings improved properties.
  • molded body in particular also includes sponges.
  • a ner process for producing a solvent-spun cellulose fiber has prevailed until industrial implementation.
  • a tertiary amine oxide in particular ⁇ -methylmorpholine- ⁇ -oxide ( ⁇ MMO)
  • ⁇ MMO ⁇ -methylmorpholine- ⁇ -oxide
  • Such a ner driving is e.g. described in US Pat. No. 4,246,221 and delivers fibers which are distinguished by high strength, a high modulus of elasticity and by a high loop strength.
  • WO 99/19555 describes a ner process for the treatment of solvent-spun. Fibers in which the fibers are brought into contact with 2,4-dichloro-6-hydroxy-1.3.5-triazine or with a salt thereof. The fibers produced in this way are characterized by better resistance to fibrillation.
  • No. 5,728,823 discloses cyclodextrin derivatives, including the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinylcyclodextrin. US 5,728,823 also describes Membranes, foils, textiles or leather to which a cyclodextrin derivative is bound. Textiles treated with cyclodextrin derivatives are suitable, for example, for absorbing unpleasant odors.
  • WO 01/48025 describes cyclodextrins which are covalently bound to a polysaccharide by means of a wetting agent.
  • cellulosic moldings which are prepared from a solution of the cellulose in an aqueous tertiary amine oxide can be treated with a textile auxiliary which comprises a cyclodextrin and / or a cyclodextrin derivative, thereby producing products with improved properties.
  • the shaped bodies are preferably fibers in a never-dried state.
  • the fibers can be treated in a never-dried state in a post-treatment stage of a continuously operating production plant.
  • cyclodextrins can include active ingredients which are then released, for example, over a longer period of time.
  • the treatment with the textile auxiliary is preferably carried out in an alkaline environment.
  • the textile auxiliary also preferably comprises a crosslinking agent.
  • Particularly preferred wetting agent is 2,4-dichloro-6-hydroxy-1,3,5-triazine or a salt thereof.
  • a cyclodextrin derivative e.g. the sodium salt of 2-chloro-4-hydroxy-1.3.5-triazinylcyclodextrin, are prepared in order to subsequently apply this derivative to the material to be treated.
  • the fibers to be treated can be added with the cyclodextrin and a wetting agent, in particular 2,4-dichloro-6-hydroxy-1.3.5-triazine, without having to prepare a nerbinding from these two substances beforehand and get good results.
  • 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 which can be obtained by the process according to the invention, and to fiber structures which contain these fibers.
  • Solvent-spun fibers with a titer of 1.3 dtex produced according to the process described in WO 93/19230 were treated in the never-dried state as follows:
  • the fibers were washed at a liquor ratio of 1:10 with a solution containing 20 g / 1 sodium salt of 2,4-dichloro-6-hydroxy-1,3.5-triazine, 16 g / 1 NaOH and 100 g / 1 of a cyclodextrin ( CAVAMAX W7, manufacturer Wacker-Chemie) impregnated for 5 minutes at room temperature.
  • the fibers were then squeezed to a moisture content of 100% -110% using a squeeze mechanism and heat-treated for 5 minutes with saturated steam (100%) at 100 ° C., washed out and dried.
  • the content of active cyclodextrin in the fibers thus produced was determined photometrically (552 nm) using the decolorization of a phenolphthalein solution and was 2.33% by weight.
  • the degree of fibrillation on the fibers was determined on the basis of the wet scrub resistance (test method according to WO 99/19555) of the individual fibers. According to this test method, the sample treated according to the invention has an average value of 210 revolutions. In comparison, an untreated fiber shows a wet abrasion value of only 40-60 revolutions. - - -
  • Example 2 The procedure was as in Example 1, with the treatment solution 20 g / 1 sodium salt of 2,4-dichloro-6-hydroxy-1.3.5-triazine, 16 g / 1 NaOH, 30 g / 1 soda and 50 g / 1 one Cyclodextrins (CAVAMAX W7, manufacturer Wacker-Chemie) contained.
  • the active cyclodextrin content in the fibers thus obtained was 1.65% by weight, the wet abrasion value was 470 revolutions.
  • Example 2 The procedure was as in Example 1, with the treatment solution 30 g / 1 soda and 100 g / 1 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin (MCT-CD; CAVASOL W7 MCT, manufacturer Wacker- Chemistry) contained.
  • MCT-CD 2-chloro-4-hydroxy-1.3.5-triazinyl-cyclodextrin
  • the active MCT-CD content in the fibers thus obtained was 1.89% by weight.
