Abstract
A method and apparatus for space-dyeing yarns, particularly fine denier yarns, including the steps of wrapping a plurality of feed yarns with a sacrificial wrapper yarn to form a composite yarn bundle, space-dyeing the composite yarn bundle, removing the wrapper yarn from around the feed yarns, and separating the feed yarns into individual yarns for further processing. An intermediate yarn product for passing through the space-dyeing machine is disclosed, as well as the end product fine denier yarns after being separated from the bundle in which dyeing took place.
Claims33
A method for space-dyeing yarns, comprising the steps of:
- (a) wrapping a plurality of feed yarns with a sacrificial wrapper yarn to form a composite yarn bundle of indeterminate length with the yarn bundle bound together along its length by wraps of the sacrificial wrapper yarn extending along the length of the yarn bundle to form a continuum of the wrapper yarn and the feed yarns;
- (b) space-dyeing the composite yarn bundle;
- (c) removing the wrapper yarn from around the feed yarns;
- and
- (d) separating the feed yarns into individual yarns for further processing.
An apparatus for space-dyeing yarns, comprising:
- (a) an yarn-wrapping apparatus for wrapping a plurality of feed yarns with a sacrificial wrapper yarn to form a composite yarn bundle;
- (b) a space-dyeing apparatus for space-dyeing the composite yarn bundle;
- (c) a wrapper yarn removal apparatus for removing the wrapper yarn from around the feed yarns;
- and
- (d) a feed yarn separating apparatus for separating the feed yarns into individual yarns for further processing.
An apparatus for space-dyeing yarns, and comprising:
- (a) yarn wrapping means for wrapping a plurality of feed yarns with a sacrificial wrapper yarn to form a composite yarn bundle;
- (b) space-dyeing means for space-dyeing the composite yarn bundle;
- (c) wrapper yarn removal means for removing the wrapper yarn from around the feed yarns;
- and
- (d) separator means for separating the feed yarns into individual yarns for further processing.
A composite yarn bundle for permitting space-dyeing of fine denier yarns, comprising:
- (a) a plurality of fine denier feed yarns integrated together in parallel configuration to form an integrated core;
- and
- (b) a sacrificial wrapper yarn wrapped around the core to form a composite yarn bundle wherein the feed yarns are maintained in integrated condition during space-dyeing, said sacrificial wrapper adapted to be removed from around the feed yarns after space-dyeing to permit separation of the core into individual feed yarns for subsequent processing.
A space-dyed, fine denier yarn, comprising:
- (a) a feed yarn of no more than 500 denier;
- (b) a plurality of colors of dye applied to the feed yarn by moving the feed yarn past a dye-applying apparatus while integrated together with a plurality of like feed yarns by means of at least one sacrificial wrapper yarn wrapped around said feed yarns to maintain the feed yarns in their integrated condition, said wrapper yarn being removed from the feed yarn after space-dyeing.
