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.

摘要： A method for producing a hollow-cylindrically shaped fibrous article stabilized by hot adhesion and an apparatus suitable to produce the same are provided. Said method comprises passing a web of gathered fiber layer carried on a conveyor belt through a heating zone, heating said web in such a way that a lower-melting component of composite fiber contained in the lower part of said web contacting the conveyor belt is not in the molten state and a lower-melting component contained in the upper part of said web is in the molten state, while separating said web from the conveyor belt, winding up said web on a take-up rod or tube in such a way that the upper surface thereof occupies the inner side of the winding, while heating the web further, cooling the wound up article and drawing out the take-up rod or tube from the shaped product.The production method of the present invention is simple and does not require complicated apparatus and the resultant product is useful for filtration.
