Title: Improvements in synthetic plastic filaments and method of making same
IPC: B29C48/05
Filed: 1953-06-15
Abstract: Molecularly oriented crystalline synthetic monofilaments having a transverse cross-section shaped like that of a double convex lens (in a diametrical plane parallel with the axis of the lens), one dimension of the filament cross-section being 6.5-30 mils., the maximum dimension of the cross section being 2-5 times and preferably 3 times the minimum dimension thereof, and the opposite edges of the filament being relatively sharp, are produced by extruding a molten plasticized crystalline polymer, copolymer or terpolymer of vinylidene chloride chemically stabilized towards light and heat through a spinneret provided with one or more orifices whose transverse cross sections are as described above, drawing the plastic filaments through an aqueous quenching bath, and continuing to draw the filaments to orient their crystalline resinous components and to give the filaments cross-sectional dimensions about one quarter to one third of those of the spinneret orifices.  The spinneret plate may be provided with a multiplicity of orifices arranged in circular configuration about the axis of the plate and may include an integral conical structure having its base on the inner face of the spinneret and its axis coinciding with the axis of the spinneret, this structure being adapted to distribute the plastic material uniformly to each of the spinneret orifices.  The filament substance may be a copolymer of 85-95 per cent of vinylidene chloride with 15 to 5 per cent of vinyl chloride.  The filament may contain one or more fluorescent pigments, such as activated metal sulphides. Specification 601,305 and U.S.A.  Specifications 414,090, 723,873 and 2,146,788 are referred to.

Title: New 3-alkoxy-2-hydroxypropane sulphonates
Filed: 1959-05-13
Abstract: Detersive compositions comprise as active ingredients a branched chain tridecyloxy hydroxy propane sulphonate of the general formula C13H27OCH2CH(OH)CH2SO3X wherein X is an alkali metal such as sodium, potassium or lithium and the C13H27 group is a branched chain tridecyl radical, preferably derived from a branched tridecyl alcohol obtained by the OXO synthesis from a branched C12 olefine such as tetrapropylene or tri-isobutylene.  A specified composition comprises sodium branched-chain 3-tridecyloxy-2-hydroxy propane sulphonate, soda ash, sodium tripoly phosphate, sodium tetra pyro phosphate and sodium silicate.  The compositions may be moulded.ALSO:The invention comprises branched-chain tridecyloxy hydroxy-propane sulphonates of the general formula C13H27OCH2CH(OH)CH2SO3X wherein X is an alkali metal and the C13H27 group is the branched chain tridecyl radical, preferably derived from a branched-chain tridecanol obtained by the oxo synthesis from a branched C12 olefine e.g. tetra propylene or tri-isobutylene.  They may be prepared by reacting a branched-chain 1 - chloro - 3 - tridecyloxy-2-propanol or 2-chloro-3-tridecyloxy-1-propanol, or a mixture of these, with an alkali metal sulphite in aqueous solution which may also contain an alkaline material such as a water-soluble inorganic alkali, for example, an alkali-metal hydroxide, a salt thereof with a weak acid, such as a carbonate or acetate, or an alkali metal alcoholate. Reaction may be effected at or above ordinary temperature and reduced or elevated pressures may be used.  Alternatively, a branched-chain tridecyloxy glycidyl ether may be reacted with an aqueous alkali metal sulphite to obtain the desired sulphonates.  Suitably, the by-product alkali metal hydroxide is substantially neutralised as it is formed, for example, by addition of an acid to maintain a pH of 6-8.  Organic solvents may be present in both reactions.  The glycidyl ether may be prepared by dehydrohalogenation of either or both of the above mentioned tridecyloxy chloropropanols, for example, by treatment with aqueous alkali metal hydroxide in the presence of at least 10% by its weight of a dialkyl sulphoxide. 1-chloro-3-tridecyloxy-2-propanol, generally admixed with the 2-chloro isomer is obtained by reacting epichlorhydrin with a branched-chain tridecanol.  Examples describe the preparation of sodium 3-branched tridecyloxy 2-hydroxy-1-propane sulphonate by both the above-mentioned methods.  The potassium and lithium sulphonates are mentioned.  The compounds may be used as active ingredients in detergent compositions (see Group III).
