Abstract

The invention relates to new finishing mixtures, which contain fatty acid alkanolamides having softening points above 70.degree. C. as anti-blocking components, for synthetic fibers, particularly fibers of polyacrylonitrile, which are used as staple fibers. The invention also relates to the use of these finishing mixtures for the finishing of staple fibers, particularly polyacrylonitrile-based staple fibers.
