    摘要： A core/sheath conjugate fiber comprises a sheath component B of an ethylene-vinyl alcohol copolymer and a core component A of a different thermoplastic polymer. In its cross section, the core component A has at least 10 projections or exists as an aligned group of at least 10 flattened cross-section core components, the distance (I) between the neighboring projections or between the neighboring flattened cross-section core components is at most 1.5 &mgr;m, the projections or the flattened cross-section core components are so positioned that their major axes are all at an angle of 90°±15° to the outer periphery of the fiber cross section, and the ratio (X) of the outer peripheral length (L2) of the core component A to the outer peripheral length (L1) of the conjugate fiber satisfies the following formula (1): X/C≧2  (1) wherein X indicates the ratio of the outer peripheral length of the core component A to the outer peripheral length of the conjugate fiber (L2/L1); and C indicates the conjugate ratio by mass of the core component A to the overall conjugate fiber defined as 1.

    摘要： The present invention relates to a fiber, which includes: 2 to 95% by weight, based on the total weight of the fiber, of at least one block copolymer, which includes: at least one polymer block (A) that includes 50 to 100% by weight of olefinic monomer units, based on the total weight of the block copolymer; and at least one polymer block (B) that includes 0.1 to 100% by weight of (meth)acrylic monomer units, based on the total weight of the block copolymer. Other embodiments of the invention include fibrous structures, non-woven fabrics, leather-like sheet materials, and dyed articles, which include the above-described fiber, and processes of making the above-described fiber. The present invention also relates to a composite fiber, and fibrous structures, non-woven fabrics, leather-like sheet materials, and dyed articles, which includes the above-described composite fiber, as well as processes for producing the above-described composite fiber.
