    摘要： Apparatus for making dual-component thermoplastic fibers, such as glass fibers, comprises a spinner having an orificed peripheral wall for centrifuging fibers from thermoplastic material, the spinner having vertically aligned compartments with first and second thermoplastic materials in alternate compartments, and a series of elongated orifices in the peripheral wall in communication with each of two adjacent compartments to enable centrifuging of both the first and second thermoplastic materials from a single orifice.

    摘要： A process of melt spinning a fibre-forming thermopias- tic polymer, more particularly polyethylene terephthalate, polyhexamethylene adipamide or polypropylene, at a minimum wind up speed of 1 kilometre per minute in which there is added to the fibre-forming polymer, between 0.1 % and 10% by weight of another polymer which is immiscible in a melt of the fibre-forming polymer, such other polymer having a particle size of between 0.5 and 3 microns in the melt with the fibre-forming polymer immediately prior to spinning and novel melt spun fibres produced by such a process and in which the other polymer is in the form of microfibrlls.

    摘要： Apparatus for making dual-component fibers (68) includes a spinner (60) having a peripheral wall (64) with orifices (90) for centrifuging the thermoplastic materials (A,B) constituting the dual-component fibers. The interior of the spinner (60) is divided into a plurality of compartments (88) by baffles (86) positioned circumferentially around the peripheral wall, the baffles being inclined at an angle of about 5° to about 75° from the vertical rotational axis (66) of the spinner, and most preferably at about 450 from the vertical; and by a divider (82) which directs the thermoplastic materials (A,B) into alternate compartments (88) so that adjacent compartments contain different thermoplastic materials. The orifices (90) are aligned with the baffles (86) but are wider than the thickness of the baffles so as to communicate with adjacent compartments and so that the thermoplastic materials are centrifuged as dual-component fibers (68).

    摘要： An apparatus is provided for making dual-component fibers (100a). The apparatus comprises a distributor (40), equipment for providing first and second thermoplastic materials (A, B) to the distributor (40), a rotatable spinner (90) and a rotation mechanism. The distributor (40) has an outer casing (50) and a divider cup (60) fixedly positioned within the outer casing (50). The outer casing (50) has first and second orifices (56, 58) extending through its peripheral wall (54). The divider cup (60) defines with the outer casing (50) first and second chambers (70, 72) for receiving first and second molten thermoplastic materials (A, B). The first orifices (56) communicate with the first chamber (70), and the second orifices (58) communicate with the second chamber (72). The rotatable spinner (90) includes first and second passages (94a, 94b) in its peripheral wall (54). The rotation mechanism rotates the distributor (40) and the spinner (90) to centrifuge layers of the first and second thermoplastic materials (A, B) through the first and second orifices (56, 58) and to centrifuge dual-component fibers (100a) through the first and second passages (94a, 94b) in the peripheral wall (54) of the spinner (90).

    摘要： Two-component fibres, having a surface area of at least 1 m 2 /g, suited for replacing cellulose fibres in the manufacture of paper and paper-like products, comprise a core of olefinic polymer and from 2 to 50% by weight of a sheath of a hydrophilic polymer, and exhibit values of tenacity higher than 3,000 meters and cohesion higher than 300 meters. They are prepared by extruding a stable emulsion formed by a mixture of a solution of the olefinic polymer with a solution of hydrophilic polymer in reciprocally immiscible solvents, at a temperature exceeding the boiling temperature of the solvent of the olefinic polymer and at least equal to the dissolution temperature of such polymer in such solvent, in a medium at a lower pressure.
