Abstract
A boucle yarn is produced by entangling a drawn core yarn and an air textured, drawn effect yarn. The air textured, drawn effect yarn provides a plurality of randomly spaced curls or loops around the core yarn to produce the boucle yarn appearance. A number of the random curls or loops are embedded in the core yarn during the entangling process.
Claims2
The method of producing a boucle type yarn comprising the steps of:
- supplying a multifilament, partially oriented, synthetic effect yarn, drawing said effect yarn, air jet texturing said effect yarn after drawing of same, supplying a multifilament, untextured partially oriented synthetic core yarn, drawing said core yarn, entangling said drawn core yarn and said air textured effect yarn in an air texturing jet, allowing said entangled yarn to stabilize and taking up the entangled yarn.
