ABSTRACT:
A processing aid is used to improve worsted and woolen processes. In the worsted process, pretreatment of wool tops with the processing aid prior to dyeing preserves fiber strength and softness. In the woolen process, addition of the processing aid to the carbonizing bath permits reduction in sulfuric acid concentration, enhances destruction of vegetable matter, and produces whiter, cleaner fiber and preserves fiber strength. If desired, the processing aid may also be introduced in the final rinse after wool scouring in either worsted or woolen processes. The preferred processing agent is epoxidized chain extended polyamide.
