| 摘要 |
The invention pertains to a method for improving bundle cohesiveness of a bundle of aramid yarns and decreasing its friction coefficient, comprising 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 mm^2/s.
