Abstract
Disperse dyed polyethylene fibers obtained by either melt spinning or flash spinning and materials produced from said fibers are provided. The process utilizes dye blends containing at least three and, more preferably, four or more disperse dyes selected from a primary color group. The individual dyes are utilized at a concentration of at lest 75% but less than 100% of the determined maximum concentration which produces crocking. HDPE and LLDPE materials are effectively dyed using disperse dye blends formulated by the invention.
