FLUID-JET FALSE-TWISTING METHOD AND PRODUCT

摘要

A process of producing an assembled yarn, including the steps of providing two o r more yarns moving downstream from a supply to a take-up, inserting alternating-direct ion zones of twist into at least one of the yarns, the at least one yarn having an area of ze ro twist between said alternating direction zones of twist, combining the at least two yarns to f orm a single, integrated yarn strand, and intermittently exposing the yarn strand to an air bl ast to create a zone of intermingled yarns at spaced-apart points along the length of the yarn strand to prevent torsional movement of one yarn relative to the other yarn. According to one pref erred embodiment of the invention, the step of exposing the yarn strand to an air blas t includes the step of intermingling the yarns at the areas of zero twist.
