<p>A composite filament having an "islands-in-sea" type cross-sectional configuration having, in one embodiment, at least two kinds of islands, wherein the two islands are different in coefficient of contraction by at least 5%, or wherein one of the filamentary islands comprises a bicomponent filamentary type or eccentric filamentary type. These filamentary islands are relatively well distributed throughout the sea component and the sum of the weight of the filamentary islands is greater than the weight of the sea. Said composite filament may be made into a fabric as a filament of an ordinary denier. It is also possible to obtain a superfine fiber product being bulky or having an improved feel by superfining and heat-treating said composite filament.</p> |
