TITLE Improved Cobulked Continuous Filament Heather Yarn Method And Product Abstract An improved method for making a continuous filament heather dyeable yarn involves cobulking in a hot fluid jet process a first unbulked yarn with a second differentially dyeable previously bulked yarn. The method enhances differential dyeability in the product when both yarns have a common type of chemical dye site and the second yarn has a greater concentration of those dye sites than the first yarn.
