Abstract
A technique for combining at least two unlike yarn ends to produce a composite yarn. One of the two unlike yarn ends is a spun yarn and the other of the two unlike yarn ends is a continuous multifilament yarn. The technique includes removing each of the two yarn ends from respective supply packages under predetermined tensions. The yarn ends are separated to maintain a predetermined included angle between the yarn ends. The separated yarn ends are then fed through an entangling jet to combine the yarn ends and collected on a take-up package. In the preferred embodiment, the included angle between the yarn ends varies between 3 and 17 degrees. The resulting air entangled yarn has an average number of 80 tacks per yard and an average loop size of 174 inch or less.
