Title: Process for the manufacture of rayon threads
IPC: D01F2/10
Filed: 1960-09-21
Abstract: High-tenacity rayon threads are made by spinning viscose into a coagulating bath containing sulphuric acid, zinc sulphate and sodium sulphate, and thereafter stretching the freshly spun filaments in an acid medium at 90 DEG -100 DEG C., the cellulose content of the viscose being from 5,0-6,5% by weight, the ratio of the sodium hydroxide content of the viscose to the cellulose content of the viscose being from 1,2:1 to 1,5:1 by weight, the zinc sulphate content of the coagulating bath being 6-9% by weight ZnSO4 and the sulphuric acid content of the coagulating bath by weight and the spinning speed S being chosen so that the equation %H2SO4=4,8+0,089S is substantially satisfied, S being the speed in metres/min. which the first tow transporting means after the jet imparts to the tow. The viscose may contain 0,5-4% by weight, based on the cellulose, of one or more modifiers, especially a mixture of the compound <FORM:0912016/IV(a)/1> where x and y are integers, and polyethylene oxide, or alternatively a block copolymer of ethylene oxide and propylene oxide; a reaction product of either cocoamine or cocoamide with ethylene oxide; cyclohexylamine or dimethylamine, or the reaction products of cyclohexylamine, phenol or imidazolone with ethylene oxide.  A further portion of carbon disulphide may be added to the viscose after the formation of the cellulose xanthate.  The coagulating bath may contain 50-300 mg. per kg. of one or more of lauryl pyridinium chloride, dimethyl formamide, cyclohexylamine and triethanolamine.  The freshly spun filaments may be conducted through a spinning tube through which the coagulating bath flows in the same direction as the tow, the rate of flow of the bath through the tube being chosen so that the minimum value of tow tension is just reached.  Specifications 794,780 and 803,089 are referred to.

Title: Improvements in or relating to a spinneret used in melt spinning highly polymerised substances
IPC: D01D5/08
Filed: 1952-12-24
Abstract: The spinneret plate described in the parent Specification is characterized in that each precious metal inlay is manufactured from unhardened tantalum in a known way, the spinning orifice is provided therein in a known way, after which the inlay is inserted into the non-precious metal extrusion plate and further drilled and the complete spinneret plate is further polished and finally is subjected to a heat treatment at a temperature not above 400 DEG  C., e.g. 350 DEG  C., until the tantalum has a hardness of at least 230 DEG  and preferably of 250-270 DEG  Vickers.  In the example, apertures are drilled in a plate of stainless steel (18 Cr-10 Ni) 6 mm. thick, each aperture consisting of an upper part of depth 3 mm. tapered with a conicity of 60 degrees, the diameter at the upper end being 6.5 mm. and at the lower end 2.7 mm., and a lower part with a conicity of 3 degrees, the diameter at the upper end being 2.7 mm. and at the lower end 2.5 mm.  Inlays are formed by punching cylindrical pieces with a diameter of 2.6 mm. from a plate 1.7 mm. thick of unhardened tantalum.  The cylindrical pieces are then pressed under high pressure to form a cup with an inner diameter of 1.8 mm. at the upper end and an inner diameter at the lower end of 0.45 mm.  The bottom of the cup is 0.4 mm. thick.  The inlays at the same time are given the conical outer shape corresponding to the lower part of the apertures in the stainless steel plate.  In each of the inlays so formed an orifice is drilled in the bottom of the cup and the inlays pressed by means of a stamp into the apertures in the plate.  Additional drilling is applied to the orifices in the inlays, and the plate with the inlays is polished.  The complete plate with the inlays is then heat treated for 24 hours at 350 DEG  C.

Patent GB-866412-A (GB)
Title: Improvements in or relating to the production of microporous filters
IPC: B29C44/00
Filed: 1958-10-15
Abstract: Films useful as microporous filters are made from a solution of a cellulose ester in an organic solvent by applying a film of said solution to the surface of a carrier and moving said carrier through a gelation zone through which moist air flows in countercurrent and then drying the film by heating it to about the beginning of its thermoplastic range.  The air flow may be heated and humidified prior to its contact with the film, and the drying may be effected by causing a stream of <FORM:0866412/IV (a)/1> heated and less moist air to flow past the film.  The gelation and drying steps may take place successively using a common conveyer belt to support the film carrier, and the air stream may move at different speeds in different regions of the gelation zone. Apparatus as shown comprises means 13 for applying a film of the solution to the surface of a carrier member 10, a conveyer 11, 12 on which the carrier member may be placed and advanced horizontally, a conduit 14 disposed about the conveyer and through which the conveyer and film move, a blower 38 blowing air through the conduit in countercurrent, heating means 42 and humidifying means 45 for the air flow, a second conduit 15 disposed about the conveyer beyond conduit 14 and through which the conveyer and film move, a blower 58 blowing air through conduit 15 in countercurrent, and heating means 59 for heating this second flow of air.  The film is stripped from the carrier member 10 after leaving the conduit 15.  In the apparatus of Fig. 7, the upper limiting wall of the gelation zone is disposed at varying heights above the conveyer belt so that varying speeds are imparted to the air stream. The apparatus of Fig. 6 is suitable for applying a film forming solution to a backing of porous paper or cloth 64. The backing material is first moistened by a liquid-feeding apparatus 164 with a suitable aqueous solution (e.g. a mixture of water, acetone and/or methyl alcohol) and is then pressed on to the glass plate 10a by spring-loaded roller 65 prior to receiving a film of solution. U.S.A. Specification 1,421,341 and German 805,039 are referred to.ALSO:Microporous films are made by applying a solution of a cellulose ester in an organic solvent to a carrier which moves through a gelative zone through which moist air flows in countercurrent, the film finally being dried by heating to near its thermoplastic range.  The cellulose ester is gradually precipitated by replacement of the solvent by water, pores then being formed by evaporation of the solvent.  Suitable apparatus is described (see Group IV(a)).
