Definitions

  • the type I crystal structure of cellulose is a crystal structure contained in the cell walls of many plants and bacterial cellulose, and cannot be synthesized artificially.
  • Natural cellulose containing cellulose type I crystal structure generally has high strength and elastic modulus, which is derived from type I crystal structure.
  • Cellulose contained type I crystals, and the relationship between the type I crystal fraction and the strength and elastic modulus was also reported.
  • the present inventors have attempted for the first time to spin regenerated cellulose long fibers by adjusting the type I crystal fraction, and as a result, obtain regenerated cellulose long fibers having high strength and high elastic modulus. succeeded in.
  • the regenerated cellulose filaments having higher strength and elasticity can be spun, as the inventors have already found, but when the type I crystal is contained in the raw material solution, By spinning the fiber so as to be 10 ⁇ m or more and 50 ⁇ m or less, it is possible to obtain a regenerated cellulose long fiber having good spinnability, high strength and high elasticity.
  • the molded article of the present invention is characterized by being formed by molding a composite resin composition contained in the regenerated cellulose long fiber resin containing the I-type crystal structure.
  • the fiber diameter is thicker than 50 ⁇ m, there was no problem in terms of spinnability even in a sample having a high I-type crystal fraction. Therefore, spinning was performed using the solutions of Sample 1 and Sample 3, and the strength and elastic modulus were measured. As a result, when Sample 1 having a I-type crystal fraction of 31.5% was used, the fiber diameter was 51.6 ⁇ m, the strength was 0.31 GPa, the elastic modulus was 17.9 GPa, and the I-type crystal fraction was 15 When 3% of the sample 3 is used, the fiber diameter is 55.1 ⁇ m, the strength is 0.26 GPa, and the elastic modulus is 14.6 GPa. There wasn't. Therefore, the average fiber diameter is preferably 50 ⁇ m or less.

Abstract

La présente invention a pour objectif de fournir de longues fibres de cellulose régénérée présentant une résistance élevée et une élasticité élevée. Dans de longues fibres de cellulose régénérée obtenues par dissolution d'une matière première de cellulose dans un liquide ionique et par essorage de ces dernières, les conditions de dissolution sont ajustées de telle sorte que la teneur en cristaux de cellulose de type I varie entre 0,1 % et 35 %, et que de longues fibres de cellulose régénérée présentant une résistance élevée et une élasticité élevée soient obtenues par essorage.
