Abstract
Abstract Textured yarn filaments having predetermined texture development characteristics are combined with other textured yarn filaments having different crimp development characteristics. A yarn made by such a process in which those filaments having lesser crimp development lie generally toward the outside of the yarn. Non-rowy carpeting is made by tufting or weaving this yarn into a backing and then further developing the crimp. Apparatus for making such yarn including means for simultaneously heating and producing different crimp development characteristics in two or more ends of yarn.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
58 words
A method of producing a textured yarn from at least two ends of yarn, comprising leading the ends on the run to a heated roller, passing each of the ends around the roller a different number of turns thereby to heat the ends to different extents, and linearly compressing the differently heated ends in a common crimping chamber.
Claim 2
Independent Claim
58 words
A method of producing a textured yarn from at least two ends of yarn, comprising leading the ends on the run to a heated roller, passing each of the ends around the roller a different number of turns thereby to heat the ends to different extents, and linearly compressing the differently heated ends in a common crimping chamber.
Claim 3
Independent Claim
39 words
A method of producing a textured yarn from at least two ends of yarn comprising heating the ends to different extents and concurrently therewith orienting the ends, and linearly compressing the differently heated ends in a common crimping chamber.
Claim 4
Independent Claim
39 words
A method of producing a textured yarn from at least two ends of yarn comprising heating the ends to different extents and concurrently therewith orienting the ends, and linearly compressing the differently heated ends in a common crimping chamber.
Claim 5
Dependent Claim
98 words
The method of claim 2 wherein said heating and orienting is accomplished by leading the ends to a pair of rollers at least one of which is heated and the second of which is driven at a faster rate than the first, passing the ends between said rollers and around and in contact with the same and passing the two ends through a different number of turns on the heated roller, and leading the then oriented and differently heated ends off the second roller to the common crimping chamber and linearly compressing the oriented and differently heated ends.
Claim 6
Dependent Claim
48 words
The method of claim 3 including forming a plug of the linearly compressed yarn within the common crimping chamber and transporting the plug through a setting zone, setting the plug of compressed yarn and taking off the combined single end of yarn from the head of the plug.
Claim 7
Dependent Claim
16 words
The method of claim 4, including entangling the filaments of the combined single end of yarn.
