Definitions

  • the fiber will be heat treated the longer and / or hotter after the precipitation bath and a solution containing more tertiary amine oxide will be used, the less NMMO the fiber has left the precipitation bath, whereas the shorter and / or the less heat treated and one the more uses less tertiary amine oxide solution, the more NMMO the fiber contains after leaving the precipitation bath.
  • Secondary fibrillation means that the fibrils are also observed in the deeper layers of the filaments. The stronger the secondary fibrillation progresses, the longer and thicker the fibrils become.
  • the fibers treated according to the invention showed a significantly reduced tendency to fibrillation.
  • the filamentation of fibers that were treated after felling and before washing received a rating of 2-3.
  • Washed and possibly dried fibers or washed and possibly dried or unwashed fiber products made from them received a rating of 3 after the treatment. 4th
  • the invention is not restricted to the use of a certain average degree of polymerization DP of the cellulose raw material. Rather, cellulose or cotton linters with a DP in the range from about 400 to 7000 can be used individually or as a mixture of celluloses with a high and low degree of polymerization.
  • the invention is also not limited to the fact that the fibers or a fabric made from them must be under a certain mechanical tension. Rather, the fibers or the textile fabrics produced therefrom can be used without mechanical tension or in a state of mechanical tension.
  • a fiber obtained by spinning an NMMO / cellulose solution, precipitating, washing and drying is drawn through a treatment bath which has a temperature of 90 ° C.
  • a treatment bath which has a temperature of 90 ° C.
  • the fiber speed and the dimensions of the treatment bath are adjusted so that a fiber dwell time of about 3 seconds results.
  • the fiber is then washed in a known manner to a residual content of ⁇ 1% by weight of NMMO and dried.
  • the tendency to fibrillation of the fiber treated in this way received a rating of 3-4.

Abstract

La tendance à la fibrillation de fibres cellulosiques filées à partir de solutions d'oxydes d'amine tertiaires et celle des produits fibreux obtenus à partir desdites fibres sont réduites grâce à un traitement avec une solution contenant un oxyde d'amine tertiaire et éventuellement un additif et sous apport de chaleur. Pour réduire la tendance à la fibrillation de fibres après précipitation et avant lavage, un traitement thermique suffit.
