DEEP-DYEING SELF-CRIMPING POLYESTER YARN

ABSTRACT OF DISCLOSURE Polyester polymer is melt spun at a spinning speed above the crimp reversal speed, the filament cross section and spinning and quenching conditions being selected to give certain crystalline structure. The resulting crimped yarn dyes deeper than crimped yarns made by other tec...
