The present invention relates to the application of lubricant to fluoropolym er yarn which enables the yarn to be drawn at a high draw ratio and is removabl e by scouring, the lubricant being thermally stable at a temperature of at lea st 120 ~C, and being removable from the yarn by scouring and comprising oil and surfactant and/or wetting agent to enable the lubricant to spread over the surface of the yarn upon application to the yarn, the lubricant comprising o il such as a C6-C20 aliphatic acid ester of a polyol and a surfactant and/or wetting agent.
