Abstract
Abstract Disclosed are novel yarns comprised of at least two, and preferably three, strands of filaments, being twisted about the other strands in random "s" and "z" directions in variant degress with filaments of each strand being interlaced together to produce a cohesive commingled yarn. The individual strands although interlaced with the other strands maintain substantial integrity in the commingled yarn and preferably have different dye affinities. Methods of manufacturing the novel yarns are also disclosed.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
83 words
The method of interlacing a plurality of strands into a commingled yarn comprising the steps of combining the plurality of strands in parallel from a supply source, then twisting the individual strands within the combination in random "s" and "z" directions in variant degrees about each other while simultaneously interlacing filaments of an each strand with filaments of adjacent strand to entrap the random twists in the commingled single yarn while maintaining substantial integrity of each strand, and thereafter winding into a package.
Claim 2
Independent Claim
83 words
The method of interlacing a plurality of strands into a commingled yarn comprising the steps of combining the plurality of strands in parallel from a supply source, then twisting the individual strands within the combination in random "s" and "z" directions in variant degrees about each other while simultaneously interlacing filaments of an each strand with filaments of adjacent strand to entrap the random twists in the commingled single yarn while maintaining substantial integrity of each strand, and thereafter winding into a package.
Claim 3
Dependent Claim
43 words
The method of claim 1, including after combining the plurality of yarns in parallel but before twisting the individual strands in random "s" and "z" directions of variant degrees, the additional step of pretwisting said combining yarns less than one turn per inch.
Claim 4
Dependent Claim
35 words
The method of interlacing a plurality of strands of claim 1 wherein at least one strand prior to twisting in random "s" and "z" directions of variant degrees is differently colored than the other strands.
Claim 5
Dependent Claim
28 words
A method of interlacing a plurality of strands wherein at least one strand has a different dye affinity than the other strands, comprising the method of claim 1.
Claim 6
Dependent Claim
26 words
The method of interlacing a plurality of strands comprising the steps of claim 1, including mechanically crimping each strand prior to combining said plurality of strands.
Claim 7
Dependent Claim
32 words
The method of interlacing a plurality of strands of claim 1 including mechanically crimping the plurality of strands after combining, but before twisting in random "s" and "z" directions of variant degrees.
Claim 8
Independent Claim
76 words
The method of making a novelty yarn composed of at least three strands of synthetic linear polymeric filaments comprising the steps of combining the strands in parallel from their sources of supply, twisting the individual strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
Claim 9
Independent Claim
76 words
The method of making a novelty yarn composed of at least three strands of synthetic linear polymeric filaments comprising the steps of combining the strands in parallel from their sources of supply, twisting the individual strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
Claim 10
Dependent Claim
33 words
The method of making the novelty yarn of claim 7, further comprising combining at least two strands of different and distinct color or shade of color according to the steps of said claim.
Claim 11
Dependent Claim
27 words
The method of making the novelty yarn of claim 7, including the step prior to combining said strands in parallel, of mechanically crimping at least one strand.
Claim 12
Dependent Claim
30 words
The method of making the novelty yarn of claim 7, comprising the additional step of mechanically crimping the strands after combining but before twisting said strands in random variant degrees.
Claim 13
Dependent Claim
29 words
The method of making the novelty yarn of claim 7, comprising the additional step, after combining said strands, of pretwisting said combined strands less than one turn per inch.
Claim 14
Dependent Claim
22 words
The method of making the novelty yarn of claim 11, comprising pretwisting said combined strands between 1/4 and 1/2 turn per inch.
Claim 15
Independent Claim
94 words
A method of interlacing a plurality of continuous strands of yarn filaments into a single commingled yarn comprising the steps of continuously feeding said strands under tension to a confined yarn interlacing zone, injecting a gas under pressure in a turbulent manner into said confined yarn interlacing zone to agitate and twist the strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
Claim 16
Independent Claim
94 words
A method of interlacing a plurality of continuous strands of yarn filaments into a single commingled yarn comprising the steps of continuously feeding said strands under tension to a confined yarn interlacing zone, injecting a gas under pressure in a turbulent manner into said confined yarn interlacing zone to agitate and twist the strands about each other along their lengths in random "s" and "z" directions of variant degrees, including no twist, while simultaneously interlacing filaments of each strand with filaments of adjacent strands to entrap the random twists in a cohesive commingled yarn.
Claim 17
Dependent Claim
18 words
The method of claim 13 including feeding said strands of yarn substantially parallel into said yarn interlacing zone.
Claim 18
Dependent Claim
24 words
The method of claim 13, including feeding said strands of yarn into said yarn interlacing zone with less than one turn per inch twist.
Claim 19
Dependent Claim
22 words
The method of claim 13, including simultaneously injecting with said gas under pressure a heated fluid into said confined yarn interlacing zone.
Claim 20
Dependent Claim
54 words
