Described are a multifilamentary yarn composed of a plurality of periodically interlaced synthetic polymeric filaments which is characterized by regular node spacing and a yarn harshness of less than about 100 and an apparatus and process for making the same.

Soft node air entangled yarn and method of production

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.
