Title: Process for the manufacture of threads from solutions of polyacrylonitrile in mineral acids
IPC: D01F6/18
Filed: 1953-09-14
Abstract: A solution of an acrylonitrile polymer in aqueous nitric acid or aqueous perchloric acid, prepared according to Specifications 701,652 or 732,117, is spun into a spinning or precipitating bath cooled to a temperature within the range from +10 DEG  to -20 DEG  C. this bath containing in aqueous solution nitric acid or perchloric acid with or without an addition of a halide, nitrate, or perchlorate of a di- or polyvalent metal, or acetic acid, and the thread so formed is stretched in the path between the spinning bath and the washing apparatus in stages to a total extent of at most 100 per cent of the length, and, after washing or washing and drying, the thread is heated and stretched to a total extent corresponding to 8-12 times the original length, including the preliminary stretching.  The salt which may be added to the precipitating bath may be a salt of calcium, magnesium, zinc, aluminium, iron, or chromium.  A solution containing 25 per cent of nitric acid, 25 per cent of acetic acid, and 50 per cent of water may be used as precipitating bath.  In an example, a copolymer comprising 91 per cent of acrylonitrile and 9 per cent of vinyl acetate is dissolved slowly and with cooling in aqueous nitric acid of 58 per cent concentration.  The solution is filtered and centrifuged.  It is then extruded at 20 DEG  C. through a tantalum spinning nozzle into a precipitating bath cooled to minus 8 to minus 9 DEG  C.  The bath consists of an aqueous solution containing 32 per cent of magnesium nitrate and 10 per cent of nitric acid.  The thread obtained passes through the bath and then through a second cooled precipitating bath containing magnesium nitrate but no addition of nitric acid.  The thread passes over a roller and is stretched between this roller and another which rotates in magnesium nitrate solution at 20 DEG  C.  It is then further stretched between this roller and another rotating in a water bath at 20 DEG  C.  The thread is then washed free from acid with water at 70 DEG  C. and is then stretched in hot glycerol at 140 DEG  C.  Preferably, the spinning solution is stored and allowed to ripen for 1-24 hours before being extruded.  If desired, the precipitating bath may initially contain no nitric or perchloric acid, but once the spinning has started the bath becomes acid since acid is introduced by the extruded spinning solution.  The precipitating liquid containing nitric or perchloric acid may be introduced and allowed to flow through the bath at a controlled rate.  For the hot stretching treatment, the thread may be heated by passing it over hot rollers or by passing it through a tube heated by electric induction to e.g. 170 DEG  C.

Title: Flexible sound records
Filed: 1928-09-11
Abstract: 320,492. Gramophone Co., Ltd., and Whyte, S. Sept. 11, 1928. Records. materials for.-The surface noise of laminated disc records of the type formed of a paper or fabric core covered with cellulose material is reduced by using both nitrocellulose and cellulose acetate or other non-inflammable cellulose as the covering material. One of the materials may be applied in sheet form and the other as a solution, or both as solutions, either kind of cellulose forming the outer layer, but it is preferred that the various layers should have substantially the same coefficients of expansion. The paper core is impregnated with paraffin wax, metal stearates, rosin, or bituminous compounds, which leave the paper waterproof after the application of heat and pressure. A solution of nitrocellulose and rosin is applied to the core and then a sheet of cellulose acetate and the whole is hot-pressed between record dies; or the core is impregnated with either an aqueous or alcoholic solution of urea or thiourea, formaldehyde resins, or phenol formaldehyde or other synthetic resin, with or without colouring matter, and pressed to remove excess of solution. The paper is then dried and spread with nitrocellulose solution, dried again and covered with cellulose acetate material. The cellulose acetate may be in the form of solution dissolved in acetone or ketones, or mixtures of acetone with any of the known solvents for cellulose esters, together with a suitable proportion of plasticizer such as ptoluene, sulphonamide, diethyl phthalate, or the like, with or without pigments and fillers such as zinc oxide, lithopone, barytes, carbon black, nigrosine, or the like. The composition of a suitable dope would be 1220 grams of cellulose acetate with 260 grams of para-toluene sulphonamide in 7 litres of a mixture of acetone (75 per cent), alcohol (10 per cent), and benzol (15 per cent), and 480 grams of lithopone. The nitrocellulose solution used consists of the lower nitrates of cellulose dissolved in acetone or other ketones or esters, such as ethyl acetate or butyl acetate, with a plasticizer such as triphenyl phosphate. A suitable composition would be 1300 grams of nitrated cotton with 200 grams ot triphenyl phosphate in 7 litres of a like mixture of acetone, alcohol and benzol, and with 600 grams of zinc oxide. When the outer layers are applied as sheets, the paper core is of smaller diameter than the cellulose sheets so that it is wholly enclosed and in this case a separate pressing operation for the overhanging edges is necessary and impregnation of the core is unnecessary.
