Abstract
In sizing and drawing of one or more textile filaments, particularly a warp sheet of multiple filaments, by successively conveying the filaments through a sizing bath, a driven squeezing mechanism, a differentially driven spaced drying roller, and a warp beam or other filament winding mechanism, the filaments are heated to a temperature of approximately 100.degree. C. and maintained in a predetermined moistened condition, e.g., by the application of saturated airborne water vapor, within the draw zone between the squeezing mechanism and the drying roller, in order to achieve a sufficiently elevated temperature for draw stretching of polyester filaments, particular POY and LOY filament, without premature drying and undesirable cracking of the sizing applied to the filaments.
