Document Type and Number:
WIPO Patent Application WO/2021/144854
Kind Code:
A1
Abstract:
Provided are a fibrillated regenerated cellulose fiber, and a fabric using the same, the fiber having a characteristic surface texture, softness, and a resilient feeling, being fibrillated by rubbing and tanning treatment in a wet state, and having an excellent surface texture and long-lasting feeling after being water-washed, thereby exhibiting high quality. Provided are: a regenerated cellulose fiber of which the surface is fibrillated and which has a degree of polymerization of 100-250, and a tensile strength of 1.0-3.0 cN/dtex (exclusive of 1.0 cN/dtex) at the time of drying; a fabric including the regenerated cellulose fiber as a constituent yarn; and a method for producing the regenerated cellulose fiber of which the surface is fibrillated, and the fabric including the regenerated cellulose fiber as a constituent yarn, the method comprising a step for modifying, in an acid solution, the regenerated cellulose fiber into yarn or fabric form, under the conditions of a temperature of 110-150 °C, a pH of 2.6-3.4, and a duration of 10-30 minutes.
