Abstract
Elements are made of a polyacetal resin, which can effectively improve the chain crosswise strength while maintaining wear resistance. Provided is a fastener element made of a polyacetal resin composition containing 5 to 30% by mass of reinforcing fibers each having an average fiber diameter of 5 to 15 μm and a numeric average fiber length of 150 to 500 μm.
Claims8
A fastener element made of a polyacetal resin composition containing 13 to 17% by mass of reinforcing fibers having an average fiber diameter of 8-11 μm and a numeric average fiber length of 200 to 270 μm, wherein the reinforcing fibers have a fiber length distribution Lw/Ln of 1.0 to 1.5 in which Ln represents the numeric average fiber length and Lw represents a weight average fiber length.
