Abstract: A method of making wax articles and lubricity to textile yarns in which paraffin wax having a particular melting temperature is heated to a temperature above the melting temperature and thereby melted. A mold is then filled with a molten wax while being chilled to a temperature. Thereafter, the mould and the wax in the mould are heated to a temperature substantially the same as the melting temperature and the wax is subsequently removed from the mould. The sequenced chilling and heating impart to the moulded wax a particular molecular structure which enhances lubricity.

Abstract: Articles are moulded from paraffin wax by melting the wax and then allowing the wax to solidify in a mould, the mould being refrigerated. The invention includes a machine for moulding the articles, and wax treated by the method.
