    摘要: The invention provides improved composite and conjugate filaments to be used exclusively in in-water submerged purposes. Each of these filaments consists of a core of vinylidene fluoride resin consisting in turn of one or more filamentary element(s), while a sheath consists of polyamide resin. The composing ratio as measured between the cross-sections of these both resins is defined by a value extending from 1/99-to 40/60, preferably from 3/97 to 30/70, still more preferably between 3/97 and 20/80.
