Abstract
A method for imparting lubricity to fibers and masses of fibers such as yarn by applying a sublimable lubricating substance to said fibers in an amount sufficient to impart lubricity to said fibers. The preferred sublimable compounds are endo-trimethylenenorbornane, trimethylnorbornane, cyclododecane, adamantane and camphor. The invention also includes novel yarns containing an effective amount of a sublimable lubricating substance.
Claims13
A method of treating fibers to lubricate the surface thereof comprising depositing between 0.005% and 5% by weight based on the weight of the fibers of at least one sublimable compound selected from the group consisting of endo-trimethylenenorbornane trimethylnorbornane, and cyclododecane from the gas phase on said fibers to impart lubricity to said fibers.
Yarn composed of fibers and containing between about 0.005 and 5% by weight based on the fibers of at least one sublimable compound selected from the group consisting of endo-trimethylenenorbornane, trimethylnorbornane and cyclododecane, said sublimable compound having been condensed in said fibers from the gas phase and imparting lubricity to said fibers.
