摘要:326,461. British Celanese, Ltd., and Taylor, W. I. Sept. 28, 1928. Apparatus formaking filaments.-For the production of artificial filaments of large crosssection, anumber of artificial filaments extruded from a plurality of spinning orifices are by meansof a fluid stream caused to converge together and to unite while they are setting and aretherefore in a sticky or tacky condition. The method is particularly applicable to the dryspinning process using solutions of cellulose acetate or other esters or ethers ofcellulose; but it may also be applied to the wet spinning of solutions such as
nitrocellulose, viscose, or cuprammonium cellulose. It is convenient to maintain aroundthe filaments, prior to their convergence and adhesion, a medium rich in solvent. Foreffecting the desired convergence of the filaments, the latter mav be passed through adouble cone device 4, Fig. 1, mounted in the cell at a short distance below the spinningnozzle 2; air is blown through the space between the inner and outer cones 5, 6, theouter cone preferably extending beyond the inner. As an alternative a sleeve or hood 15,Fig. 2, may be adjustably mounted on the candle 16, the lower portion of the hood beingclosed by a hinged plate 18 in order to maintain within the hood an atmosphere rich insolvent vapour; the plate is slotted to permit the passage of the filaments, and in thecentre of the plate there is provided an incomplete ring 21 having a number of
perforations or slots 22 or a single slot through which inwardly-directed jets of air areprojected on the filaments. The united filaments may be withdrawn through an opening10, Fig. 1, in the side of the cell, passed round a feed roller 11 which may be run at aspeed sufficient to stretch the filaments and finally wound on a roller 12. The filamentsobtained may be used to produce figured, pattern or other effects in woven or knittedmaterials, and they may be used in conjunction with other artificial threads of the same ordifferent types or with natural filaments or fibres; they may be doubled or twisted withother yarns. Specification 322,557 is referred to.
