Abstract
Space-dyed textile strands are provided by a process which comprises contacting each of the substantially flat ends of a wound yarn package with a color modifying agent, withdrawing the yarn from the yarn package and rewinding the yarn in reverse order into a second yarn package having at least one substantially flat end, and contacting each of the flat ends of the rewound yarn package with a color modifying agent. The color modifying agent can comprise, for example, a dye, a chemical compound effecting the absorbtivity of dyes or the like. The yarn is withdrawn from the second yarn package, woven or tufted into a carpet, for example, and dyed, resulting in a carpet having random, small flecks of contrasting color therein.

A process for space dyeing of yarn, which comprises providing a first wound yarn package having at least one substantially flat end having exposed yarn reversals, contacting each of said substantially flat ends of said first yarn package with a color modifying agent, withdrawing said yarn from the said first yarn package, rewinding said yarn in reverse order into a second yarn package having at least one substantially flat end having exposed yarn reversals, and contacting each said flat ends of said second yarn package with a color modifying agent.
A process for providing random dyed multi-ply yarn, which comprises:
- providing a first wound yarn package having at least one substantially flat end having exposed yarn reversals;
- contacting each of said substantially flat ends of said first yarn package with a color modifying agent;
- withdrawing said yarn from said first yarn package, and rewinding said yarn in reversed order into a second yarn package having at least one substantially flat end having exposed yarn reversals;
- contacting each of said flat ends of said second yarn package with a color modifying agent;
- contacting each of said flat ends of said second yarn package with a color modifying agent;
- repeating the foregoing process with a second portion of yarn to form a third and a fourth yarn package;
- rewinding said fourth yarn package into a fifth yarn package;
- and
- combining the free end of said second yarn package with the free end of said fifth yarn package to form a randomly dyed, two ply yarn having an increased degree of randomness.
