Abstract
A method improves bundle cohesiveness of a bundle of aramid yarns, and decreasing its friction coefficient. The method includes adding to the bundle of yarns 0.1-3.0 wt. %, based on the yarn weight, of a water-soluble or water-dispersible film forming binding agent, followed by treating the bundle of yarns with an oil having an intrinsic viscosity less than 100 mm2/s.
