Patent

CA 2114026

Fibers such as caustic-treated non-round polyester fibers are prepared having certain lubricants strongly adhered to the surfaces thereof. These fibers are prepared by contacting the fibers, such as immediately prior to a crimping means, with a suitable heated hydrophilic lubricant in a processing operation followed by heating to dry or "bake" the lubricant onto and/or into the surface of the fibers.

On prépare des fibres, telles que des fibres en polyester non rondes ayant subies un traitement alcalin, aux surfaces desquelles adhèrent fermement certains lubrifiants. On prépare lesdites fibres en les mettant en contact, par exemple, immédiatement avant leur sertissage, avec un lubrifiant hydrophile réchauffé de façon appropriée dans une opération de traitement suivie par un réchauffement servant à sécher ou à ''cuire'' le lubrifiant à l'extérieur et/ou à l'intérieur de la surface desdites fibres.
