Abstract
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 The yarn is withdrawn from the second yarn package, woven or tufted into a carpet, for example, and dyed, resulting in a carpet having random, small flecks of contrasting color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.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
90 words
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.
Claim 2
Dependent Claim
90 words
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.
Claim 3
Dependent Claim
25 words
The process of claim 1 wherein each of said yarn package is in the form of a low taper cone having two substantially flat ends.
Claim 4
Dependent Claim
13 words
The process of claim 1 wherein said color modifying agent is a dye.
Claim 5
Dependent Claim
12 words
The process of claim 3 wherein said dye is a disperse dye.
Claim 6
Dependent Claim
44 words
The process of claim 4 wherein said yarn is a synthetic polymer and each of said substantially flat ends of said yarn packages is subjected to a heat treatment at a temperature in the range of 200° and 260° C. to fix the dye.
Claim 7
Dependent Claim
20 words
The process of claim 1 wherein said color modifying agent comprises a compound capable of increasing the absorption of dyes.
Claim 8
Dependent Claim
20 words
The process of claim 1 wherein said color modifying agent comprises a compound capable of decreasing the absorption of dyes.
Claim 9
Dependent Claim
36 words
The process of claim 1 where said color modifying agent is contacted with each of said flat ends by contacting each end of the yarn package in a receptacle provided with resilient, absorbent dye applicator means.
Claim 10
Dependent Claim
18 words
The process of claim 1 wherein said color modifying agent comprises a dye and a chemical binding agent.
Claim 11
Dependent Claim
12 words
The process of claim 9 wherein said chemical binding agent is starch.
Claim 12
Dependent Claim
26 words
The process of claim 1 wherein the yarn is withdrawn from the second yarn package, tufted into a carpet backing, and said tufted carpet is dyed.
Claim 13
Dependent Claim
27 words
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;
Claim 14
Dependent Claim
27 words
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;
Claim 15
Dependent Claim
142 words
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.
Claim 16
Dependent Claim
142 words
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.
