Title:
METHOD FOR MANUFACTURING FLAME-RETARDANT SHORT FIBER LAMINATE USING RAYON SHORT FIBERS AND LAMINATE OF THE FLAME-RETARDANT RAYON SHORT FIBERS
Document Type and Number:
WIPO Patent Application WO/2022/060053
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing flame-retardant rayon short fibers, and a flame-retardant rayon short fiber laminate using the short fibers. More specifically, the present invention is characterized in that, when a web made of short fibers is impregnated with a flame-retardant solution having starch and inorganic powder mixed therein and then dried, the inorganic powder is adsorbed to the short fibers by the starch, so that the removal thereof does not occur, and thus the flame-retardant efficiency is increased, and when a laminate is formed by using the short fibers, the strength thereof is improved, thereby improving workability and moldability.
