A composition suitable for use in sizing viscose rayon fibres and yarns comprises a solution or suspension containing linseed oil or other oxidizable oil and, as an antioxidizing and stabilizing agent, a compound obtained by the reaction of a fatty acid with triethanolamine, the agent being present in the composition in an amount of 3-30% by weight based on the weight of the oil. The fatty acid used to prepare the compound may contain 10-24 carbon atoms and the compound may be triethanol-amine stearate or oleate. The composition may be in the form of an aqueous dispersion or as a solution in petrol, heptane, benzene, toluene or trichloroethylene.ALSO:Viscose rayon fibres and yarns are sized by passing them through a single bath containing, in suspension or solution, linseed oil or other oxidisable oil and as an antioxidizing and stabilizing agent, a compound obtained by the reaction of a fatty acid with triethanolamine, the agent being present in the bath in an amount of 3-30% by weight based on the weight of the oil. The fatty acid used to prepare the compound may contain 10-24 carbon atoms and the compound may be triethanolamine stearate or oleate. The composition may be used in the form of an aqueous dispersion or as a solution in petrol, heptane, benzene, toluene or trichloroethylene. The fibres or yarns may be processed in the form of cakes or hanks and may then be centrifuged and dried. |
