Abstract
The present invention is an apparatus and method of making yarn for carpet that exhibits a high degree of color pop. More specifically, in one aspect, the present invention comprises an apparatus and method that comprises supplying a plurality of yarns, false-twist the plurality of yarns, and passing the consolidated yarn through a downstream entangling assembly to tack at least a portion of the consolidated yarn. Another aspect of the present invention passes at least one of the plurality of yarns through one of a plurality of second entangling assemblies positioned upstream of the false-twist apparatus.
Claims23
A yarn manufacturing apparatus, comprising:
- a) a false-twist assembly, comprising:
- i) a body member having a first end, an opposed second end, and a central longitudinal axis, the body member defining a plurality of bores extending parallel to the central longitudinal axis therebetween the first and second ends, each bore being spaced from the central longitudinal axis;
- and
- ii) a driver constructed and arranged to rotate the body member in an oscillating motion so as to impart a false-twist into each yarn being passed into each of at least two bores of the plurality of bores to form a consolidated yarn;
- b) a first entangling assembly positioned substantially adjacent and downstream of the false twist assembly to tack at least a portion of the consolidated yarn as the consolidated yarn passes therethrough the first entangling assembly, the first entangling assembly being positioned downstream of the second end of the body member;
- and
- c) at least one second entangling assembly positioned upstream of the first end of the body member, at least one yarn passing through the second entangling assembly prior to the communication of the at least one yarn to the body member to tack at least a portion of the yarn that passes therethrough the second entangling assembly.
A method of manufacturing yarn, comprising:
- supplying a plurality of yarns;
- passing at least one yarn of the plurality of yarns through one of a plurality of second entangling assemblies to tack at least a portion of the yarn;
- providing a false-twist assembly, comprising a body member having a first end, an opposed second end, and a central longitudinal axis, the body member defining a plurality of bores extending parallel to the central longitudinal axis therebetween the first and second ends, each bore being spaced from the central longitudinal axis;
- rotating the body member in an oscillating motion so as to impart a false-twist into each yarn being passed through each of at least two bores to form a consolidated yarn;
- and
- passing the consolidated yarn through a first entangling assembly to tack at least a portion of the consolidated yarn immediately subsequent the step of forming the consolidated yarn.
A method of manufacturing yarn, comprising:
- supplying a plurality of yarns;
- passing at least one yarn of the plurality of yarns through one of a plurality of second entangling assemblies to tack at least a portion of the yarn prior to the false twist step;
- false-twisting the plurality of yarns to form a consolidated yarn;
- and
- passing the consolidated yarn through a first entangling assembly to tack at least a portion of the consolidated yarn immediately subsequent the false twist step.
