Abstract
A finish for polyamide yarn comprising 0.2 to 10 weight percent of an amide of polyamine and C.sub.12 -C.sub.50 aliphatic dibasic acid, or an alkali metal salt of the said amide, functioning to prevent the oligomer in polyamide yarn from being extracted out on the polyamide yarn surface during storage so as to prevent fluffs and yarn breakage due to scum generation in down-stream process.
