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.

摘要： PROBLEM TO BE SOLVED: To obtain a tow excellent in high-speed openability with no tacky adhesion among single fibers and an opening coefficient at a specified level or higher, and useful for e.g. nonwoven fabrics, by bundling thermoplastic fibers having sensible crimps and each a specific single fiber fineness and the specific whole fineness. SOLUTION: This two, >=3 in opening coefficient, is a fiber bundle consisting of at least one kind of thermoplastic fibers having sensible and/or latent crimps and 0.5-100 denier in single fiber fineness and 10000-300000 in the whole fineness. and selected from polyolefin-based fibers, polyester-based fibers and polyamide- based fibers. It is preferable that the thermoplastic fiber is a conjugate fiber made up of at least two components >=15 deg.C in melting point difference and has modified cross-section structure.
