  • Patent number: 4323626
    Abstract: 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.
    Type: Grant

  • Patent number: 4100009
    Abstract: 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.
