Title: Dry spinning process for fibreforming polymers
IPC: D01D4/04
Filed: 1971-10-18
Abstract: 1349019 Dry-spinning process E I DU PONT DE NEMOURS & CO 18 Oct 1971 [19 Oet 1970] 48405/71 Heading B5B A process for dry-spinning textile filaments from a spinning solution of a fibre-forming polymer in a solvent comprises passing the solution through a spinneret assembly wherein air is removed from the said assembly before the solution is passed therethrough by replacing the air with a gas which is more soluble than air in the spinning solution. The polymer may be a "Spandex" (Registered Trade Mark) polymer, defined as a long chain synthetic elastomer comprised of at least 85% of a segmented polyurethane, an aromatic polyamide, or an acrylonitrile polymer. The term acrylonitrile polymers includes homopolymers and polymers containing at least 85% by wt. of acrylonitrile units, with suitable comonomers. Specified spinning solvents include dimethyl formamide and dimethylacetamide, and the gas more soluble than air must not be unduly corrosive to equipment, should not be toxic for safety reasons and must be inert in the solution to be spun. For solutions of acrylic or spandex polymer in dimethyl formamide or dimethylacetamide carbon dioxide is the preferred gas. Nitrogen is less soluble than air in solutions of acrylic polymer or spandex polymer in dimethyl formamide and dimethylacetamide, and is not a suitable gas according to this invention for replacement of air in spinneret assemblies or spinning fibres from a solution. Oxygen is not inert to the solution to be spun. Desirably, at starting, the solution to be spun through the spinneret should be at as low a temperature as convenient. This result is thought to be due to the increase in solubility of the soluble gas in the solution at lower temperatures. The dry spinning apparatus shown may be used. As shown, spinning solution is delivered to conduit 1 which passes through heating chamber 3. Heat transfer fluid enters chamber 3 through passage 5 and exits through passage 7. Spinning solution from conduit 1 flows through the spinneret assembly consisting of pack body 9, filter pack 11, distributer plate 13, spinneret 15, retainer plate 17, bolt 19, and threaded ring 21. Hot gas from a source not shown is delivered through conduit 23 to gas distributer chamber 25 which is insulated from the heating chamber as shown and from which it flows through turbulence suppressing means consisting of perforated plate 27 and screen 29 to contact the filaments in the spinning cell. The filaments lose the bulk of the solvent to the hot, evaporative medium as they progress through the spinning cell (not shown) position below Fig. 1, and are withdrawn at a carefully regulated speed for subsequent processing.

Title: Process for the production of decorative and or protective coatings
IPC: C09D5/02
Filed: 1971-10-21
Abstract: 1373498 Coating process E T E R N I TWERKE LUDWIG HATSCHEK and UOBSA 21 Oct 1971 [30 Oct 1970] 49022/71 Heading B2E [Also in Division C3] Decorative and/or protective coatings on water-absorbant substrates are produced by mixing an aqueous dispersion of a saturated water-insoluble synthetic resin with a polymerisable organic liquid capable of swelling the synthetic resin particles, coating the substrate with the resultant mixture, and then hardening the coating by free radical polymerisation and/or free radical graft copolymerisation of the organic liquid effected thermocatalytically, or by irradiation with ultra violet light, or by exposure to high energy rays. (Graft copolymerisation is stated to occur as the major reaction when hardening is effected with high energy radiation.) Examples of the waterinsoluble synhtetic resins are vinyl chloride polymers and copolymers (e.g. with vinyl acetate), acrylic or methacrylic polymers and copolymers, styrene polymers and copolymers (e.g. with butadiene or acrylic acid), chlorinated rubber and polyurethanes. Suitable polymerisable liquids include vinyl acetate, vinylidene chloride, vinyl sulphonic acid, acrylic acid, acrylonitrile, acrylic or methacrylic esters, styrene, vinyl carbazole, esters and ethers of allyl alcohol, and maleic acid and its derivatives. The liquid may comprise a higher boiling polymerisable component to prevent evaporation losses, e.g. hydroxyalkyl (meth) acrylates and other (meth)acrylic esters of glycols or other polyalcohols, and allylic esters of polybasic acids. Thermocatalytic hardening may be effected with a peroxide, azo compound or redox system. With ultraviolet radiation, a sensitiser such as benzoin, benzophenone, anthraquinone and their derivatives or certain sulphur- or halogen-containing compounds is normally used. The preferred form of high energy radiation is electron radiation. Optional components in the coatings include pigments, finely divided fillers and silicones. Examples of water-absorbant substrates are wood (e.g. plywood), fiberboard, cardboard, paper; textiles, concrete, asbestos cement and natural stone. The coating mixture can be applied to the substrate by painting, pouring on, or spraying.
