Abstract
A method of manufacturing twistless or substantially twistless yarn consisting of dry drafting a sliver, moistening the drafted sliver with a water-soluble cation-active polymer bonding agent, drafting the sliver in the web state, false twisting the sliver, activating the bonding agent by drying the sliver on a heated drum and winding the resultant yarn up on cross wound cheeses, and a yarn manufactured according to this process.
