METHOD FOR MANUFACTURING GLASS CHOPPED STRAND AND METHOD FOR MANUFACTURING GLASS CHOPPED STRAND MAT

摘要

Provided are: a method for manufacturing glass chopped strands that have good dispersiveness; and a method for manufacturing a glass chopped strand mat with no unevenness in the density of the glass chopped strands. The method for manufacturing the glass chopped strands includes cutting, into a predetermined length, a doubled glass strand (S2) which combines glass strands (S1) drawn from each of a plurality of cakes (C1 to C8). The doubled glass strand (S2) is formed by combining first glass strands that are twisted clockwise when drawn from a part of the plurality of cakes (C1 to C4) and second glass strands that are twisted counterclockwise when drawn from the rest of the cakes (C5 to C8), and the glass chopped strands are manufactured from this doubled glass strand.
