Patent GB-564737-A (GB)
Title: Improvements in or relating to the sizing of artificial textile materials
IPC: D06M15/15
Filed: 1942-12-28
Abstract: Textile materials containing fibres of synthetic linear polymers such as nylon, polyvinyl compounds, polyvinylidine compounds or polystyrene, are sized by applying to them an aqueous dispersion of a water-insoluble wax, a water-insoluble oil, and casein.  Instead of the wax and oil, petroleum jelly or other water-insoluble substance of similar consistency may be used.  The textile material may be treated in loose form, or as a sliver or yarn, or in other form.  The oil may be a light mineral oil, a vegetable oil, or a synthetic ester of the kind described in Specification 487,949.  The wax may be a vegetable or animal wax or it may be a hydrocarbon.  The dispersion may contain an antiseptic such as formaldehyde, or a chlorinated cresol or xylenol.  An emulsifying agent of oil soluble-water insoluble, oil insoluble-water soluble, or oil soluble-water soluble type may be present.  Oleyl alcohol, stearamide, acrylic and alkyd resins, sodium oleate, ammonium ricinoleate, sodium alkyl sulphonates, morpholine oleate, and cyclohexylamine stearate, are specified emulsifying agents.  The dispersion may contain glycerine, sodium lactate or sodium hexametaphosphate as antistatic compound; soap-forming fatty acids, colouring matter for identification purposes, organic amino compounds or other antioxidants; aldehydes, tannic acid or chromium salts as insolubilising agents. In an example, the sizing composition comprises casein, borax, paraffin wax, polymerized methylcyclohexanol oleate (a synthetic oil), parachlor-metacresol, and water.  In another example, the composition comprises casein, borax, white ceresin wax, light mineral oil, stearic acid, sodium hexametaphosphate, sodium trichlorphenate, and water.  Specifications 499,371, [Group III], and 557,783 also are referred to.ALSO:Textile materials containing fibres of synthetic linear polymers, such as nylon, polyvinyl compounds, polyvinylidine compounds or polystyrene, are sized by applying to them an aqueous dispersion of a water-insoluble wax, a water-insoluble oil, and casein.
