Abstract (en)
[origin: EP3690087A1] There are provided a composite fiber from which a fabric-feel molded article having a fiber texture can be obtained and a molded article using the composite fiber.The composite fiber has a sea-island structure in which, in a sea component 1 of which a cross section vertical to a longitudinal direction is made of a first thermoplastic resin, a plurality of island components 2 made of a second thermoplastic resin higher in melting point than the first thermoplastic resin is interspersed. Woven cloth, knitted cloth, or braided cloth is formed using a composite fiber 10 for two or more axes in which the sea component 1 has a parallel light transmittance of 5% or more, the island components 2 have a crystallinity of 10% or more, and the volume ratio of the island components 2 is 50 to 90%, and is thermally molded to form a molded article.
