Abstract
A soil-resistant spin finish composition based on select derivitized polyethers is provided that can be applied to a fiber at the earliest stages of spinning, can remain on the fiber through the entire manufacturing process, and can be left on the fiber in the final article of commerce. The spin finish composition provides excellent fiber lubrication during high-speed spin processing, yet is sufficiently soil resistant to negate the need for scouring the final fiber construction, even absent the presence of additional coatings or agents.
