A composite fiber is provided in which two types of segments A and B are present in a fiber transverse section, where the segment B has a cross-sectional area smaller than a cross-sectional area of the segment A, and is formed of two types of polymers combined in a side-by-side type or an eccentric core-sheath type; and where a multifilament is composed of two types of filaments A and B, in which one or more of the filaments B are present between any two of the filaments A in the multifilament; and where a woven or knitted fabric is subjected to water repellent finish and includes a multifilament composed of two types of filaments A and B, in which one or more of the filaments B are present between any two of the filaments A in the multifilament.
A composite fiber in which two types of segments A and B are present in a fiber transverse section, wherein the segment B has a cross-sectional area smaller than a cross-sectional area of the segment A, and is formed of two types of polymers combined in a side-by-side type or an eccentric core-sheath type.
A multifilament composed of two types of filaments A and B, wherein one or more of the filaments B are present between any two of the filaments A in the multifilament, and the filament B has a smaller fiber diameter than a fiber diameter of the filament A and is formed of two types of polymers combined in a side-by-side type or an eccentric core-sheath type.
A woven or knitted fabric subjected to water repellent finish, comprising a multifilament composed of two types of filaments A and B, wherein one or more of the filaments B are present between any two of the filaments A in the multifilament, the filament B has a smaller fiber diameter than a fiber diameter of the filament A and is formed of two types of polymers combined in a side-by-side type or an eccentric core-sheath type, and a sliding angle of water drop is 1 to 20 degrees.
