<p>An acrylic composite fiber which comprises 10 to 40 wt % of cellulose acetate and/or cellulose, 60 to 90 wt % of an acrylonitrile based polymer and has a fiber structure wherein in a cross section perpendicular to the fiber axis, the component of cellulose acetate and/or cellulose forms an island component and the component of an acrylonitrile based polymer forms a sea component. The acrylic composite fiber has a new feeling different from that of a conventional cellulose acetate fiber, a cellulose fiber or an acrylonitrile based fiber, is excellent in spinability, physical properties as a fiber and the capability of passing through a spinning process, and also is excellent in functionality, especially in deodorizing function and moisture absorption and retention. The moisture absorption and retention is improved by a heat treatment under an alkaline condition in the production process of the fiber.</p> |
