摘要： The heat-adhesive fine composite fibers of the present invention have a denier within the range of 1-20, and consist of as a first component, a crystalline polypropylene and as a second component, an ethylene-vinyl acetate copolymer, a saponification product thereof or a mixture of any of these materials with polyethylene, the content in said second component, of vinyl alcohol and/or vinyl acetate units based upon the total of vinyl acetate, vinyl alcohol and ethylene units being 0.5-18 mol %, and said second component forming at least one part of the fiber surface of said fibers. These fine composite fibers are superior in low temperature heat-adhesiveness, in adhesiveness with foreign raw materials, and in low crimpability. Further the fine composite fibers in which the second component has a specific density of 0.93 or less show almost no crimpability and are useful for wet-type non-woven fabrics. When a polypropylene having a Q value of 3.5 or less is used as the first component, the composite fiber can be obtained by spinning process alone with sufficient fiber strength, and the composite fibers having almost no sensible and latent crimping are very suitable for wet type non-woven fabrics.
