Abstract (en)
The present invention addresses the problem of providing a high-strength polyamide multifilament from which stockings having excellent wearability and also having excellent transparency and texture can be produced. The problem can be achieved by a polyamide multifilament having a total fiber fineness of 6 to 20 dtex, loop strength of 12 cN/dtex or more, and a degree of flatness, which is represented by the ratio (b/a) of a longer diameter b of a transverse section of a single fiber to a shorter diameter a of the transverse section, of 1.5 to 5.0.
