Abstract (en)
A polyphenylene sulfide monofilament has a phenylene sulfide unit as a main structural unit and satisfies (1) to (5):(1) a fineness of 6 to 35 dtex;(2) a breaking strength of 3.4 cN/dtex or more;(3) a breaking elongation of 24% to 45%;(4) a 5% modulus of 1.0 to 1.6 cN/dtex; and(5) a 10% modulus of 1.4 to 2.3 cN/dtex.
