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.
Claims5
In processes for the manufacture of twistless or substantially twistless yarn which comprises drafting a sliver of staple fiber to a thinner fiber strand, false twisting the fiber strand and bonding it with the aid of a bonding agent, which bonding agent can be removed from products manufactured using the twistless yarn, the improvement consisting essentially in employing a water-soluble cation-active quaternized starch polymer as the bonding agent.
A twistless or substantially twistless yarn manufactured by drafting a sliver of staple fiber to a thinner fiber strand, false twisting the fiber strand and bonding it with the aid of a water-soluble cation-active quarternized starch polymer bonding agent, which agent can be removed from the final product.
