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.

Finishing mixtures for synthetic fibers characterized in that the dry residue of said mixtures contains at least 30% by weight phosphoric acid alkyl ester,
- 0 to 30% sulfuric acid alkyl ester,
- 10 to 30% monoalkyl polyglycol ether or monoacyl polyglycol ester or mixtures thereof and
- 10 to 50% fatty acid monoalkanolamides corresponding to the following general formula
- R.sub.1 --CO--NH--R.sub.2 --OH
