ABSTRACT:
A chemical, useful as a warp size, which is soluble in water at one temperature and insoluble at a different temperature, is applied to textile yarns in the process known as slashing. By manipulation of temperatures the chemical is reclaimed and recycled as a warp size. The water from the reclamation step may be recycled, or the water may be discharged with a minimum of waste treatment.
