Definitions

  • the degree of substitution is the number of hydroxyl groups substituted by carbamate per monosaccharide unit.
  • the DS can vary and reach at most the number of OH groups per monosaccharide unit.
  • the maximum DS 3.
  • a suitable and sufficient DS for the present invention depends on the mode of application and can be changed by selecting the saccharide substrate and the reaction temperature and reaction time.
  • the derivatizing melt thus produced can now be processed into shaped articles by the usual methods, e.g. by extrusion through nozzles or dissolution of the cellulosecarbamat conceptionigen polymer in sodium hydroxide solution and precipitation in an aqueous precipitation bath. If the cellulose carbamate solution is introduced directly into an aqueous solution, cellulose carbamate in amorphous form is obtained.
  • the deformation of the materials takes place by the action of heat and pressure.
  • the material samples described below were treated at a pressure of around 1.0 bar for a period of 30 seconds to 2 minutes at temperatures of 150 ° C to 220 ° C.
  • the formation of the cellulose carbamate can be confirmed on the basis of the N content and the IR spectrum, wherein the nitrogen content increases with the use of said formulations with increasing treatment temperature and treatment time up to about 2 wt.% N from the weight of the material.
  • N about 1% by weight of N is obtained after treatment at 190 ° C. for 2 minutes or 220 ° C. for 30 seconds; for a treatment at 220 ° C. for 2 minutes, formulations 1 1, 6 Wt.% N and in formulation 3 2.0 wt.% N bound in the polymer (this corresponds to a degree of substitution DS of 0.2-0.25).
  • Fig. 2 shows the nitrogen content in wt.% Of the treated cellulose
  • the treating solution was prepared by mixing polyethylene glycol (20% by weight), urea (60% by weight) and sodium acetate (20% by weight). The molecular weight of polyethylene glycol was varied from 4000 to 6000 from 2000. A sufficient amount of deionized water was added. Viscose fabric stored under standard conditions (20 +/- 2 ° C, 65 + 1-2% RH) for at least 48 hours was impregnated with a pad at the above solution at room temperature under 1 bar pressure at a speed of 1 m / min. Thereafter, the textile was dried in a tenter dryer at 105 ° C for 40 seconds to remove water. Thereafter, the dried textile was treated at 1 bar pressure for 2 min at 100 ° C to 250 ° C.
