ABSTRACT:
This invention is to a process for sizing spun cotton yarns, especially dyed spun cotton yarns. The process entails treating a cotton-containing yarn with a solution polyacrylamide polymer. The use of this polymer system with a spun cotton yarn has been discovered both to overcome the previous excessive brittleness which had precluded use of polyacrylamide polymers as a size and to produce a fabric which can be overdyed without prior removal of the size.
