Abstract

An apparatus for preparing regular soft nodes in multifilamentary yarns composed of synthetic polymeric filaments includes at least two interlacers, each having a separate yarn passageway. The passageways are arranged in series so that each interlacer operates independently of the other on yarn traveling consecutively through each interlacer and so that yarn tension does not exceed 100 grams per 1000 denier.
