<p>POLYESTER YARNS DYED ACCORDING TO THE SPACE-DYEING METHOD Polyester yarns are dyed according to the spacedyeing process by using yarns in the printing process, which consist of polyethylene terephthalate fibers spun at velocities of at least 4,000 m/min., and steam-set at temperatures of up to 102.degree.C. The fibers may be continuous filament fibers or staple fibers; preferably, yarns are used which have been spun at a speed of at least 4,500 m/min., in particular at least at 5,000 m/min. The devices used for space-dyeing may be those customarily used for the space-dyeing of polyamide yarns.</p> |
