Pulpeartige kurze Fasern

摘要

Pulp-like short fibers prepared from liquid crystal polyesters capable of forming an anisotropic melt phase at a temperature of 200 DEG C. to 400 DEG C. and having a molecular weight of 2,000 to 100,000 are provided. These fibers consist of microfibrils and have the following highly-oriented fiber characteristics and properties: (a) Tensile strength: 5-30 g/den.; (b) Modulus of elasticity: 200-1,500 g/den.; (c) Orientation angle as determined by an X-ray diffraction: below 20 DEG ; (d) Thickness distribution: 0.1-50 mu m; (e) Length distribution: 0.1-50 mm; and (f) Specific surface area as determined by a nitrogen adsorption method: 3-30 m2/g.
