摘要： A method is disclosed including causing a preform 1 that is softened to pass from an inner side of a container-shaped member 10 having a shape of a container having a through hole 12 at a bottom thereof through the through hole 12. The preform 1 includes a resin. At least an inner surface 10i of the container-shaped member 10 is formed of a material including glass, a heat-resistant resin, or aluminum as a main component. In one embodiment of the present invention, the preform 1 is heated while the preform 1 and a metallic member 20 in which the container-shaped member 10 is disposed are not in direct contact with each other, and the preform 1 softened thereby is caused to pass through the through hole 12 and then through a tubular portion 26 of the metallic member 20 to shape the preform 1 into a fibrous shape.

摘要： Provided is a thermal molding method for producing a thermally molded article having excellent abrasion resistance at its melt-fused part. Polyamide 6 and a copolyester are prepared separately. The copolyester contains terephthalic acid, ethylene glycol, and 1,4-butanediol as copolymerization units. The copolyester may further contain ε-caprolactone and/or diethylene glycol as a copolymerization unit. A multifilament yarn in which core-sheath type composite filaments each containing a core component and a sheath component at a ratio of 1 to 4:1 by mass are bundled is produced by a composite melt-spinning method using the polyamide 6 as the core component and the copolyester as the sheath component. Using the multifilament yarn, a product of filaments is produced by weaving, knitting, knitting and braiding, or braiding. The product of filaments is heated to melt the copolyester and fuse the core-sheath type composite filaments to each other while retaining the initial filament form of the polyamide 6, thus thermally molding the product of filaments.

摘要： The present invention relates to a process for producing electrospun fibers comprising polyethyleneimine nanoparticles (PEIN). The use of PEIN permits the antibacterial finishing of electrospinnable polymers, provided that these polyethyleneimine nanoparticles are particles of derivatized polyethyleneimine (PEI), since pure underivatized PEI has no antibacterial action. Preference is given to using quaternized polyethyleneimine. The electrospinnable polymers can be coated with PEIN during and/or after the electrospinning. The polymeric fibers obtainable by the process according to the invention can be used for textile fibers, for example for the production of fibers for functional apparel or for fibrous nonwoven webs or fibrous mats for cell culture substrates.

摘要： An assembly of fibers composed of at least two dissimilar fiber-forming polymers, characterized by the fact that(1) it consists of numerous fibers,(2) at least 90% of said fibers have a non-circular cross-sectional shape,(3) the cross sections of at least 50% of said fibers differ from each other in at least one of shape and size, and(4) at least 50% of said fibers each have in their cross section taken at right angles to the fiber axis at least two side-by-side coalesced blocks of at least two dissimilar fiber-forming polymer phases with at least a part thereof being exposed to the peripheral surface of the fiber, at least one of the number, shape and size of the blocks varying from fiber to fiber. The assembly of fibers can be produced by extruding a molten macroblend composed of many molten phases of at least two dissimilar fiber-forming polymers through a mesh spinneret having many small openings; and taking up the extrudates from the small openings while cooling them by supplying a cooling fluid to the extrusion surface of said spinneret or to its neighborhood, whereby said extrudates are converted into numerous separated fine fibrous streams and solidified; characterized in that said macroblend is prepared by coalescing many distinct molten phases of at least two dissimilar polymers in such a manner that in a phantom cross section of the molten macroblend taken parallel to the spinneret, there exist many effective continuous boundary lines between the molten phases of dissimilar polymers each of which lines has a length larger than one-fourth of the length of a partitioning member which defines one small opening in the spinneret, whereby said many boundary lines are cut with the partitioning members in the spinneret.
