Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
27 words
The product of claim 1 wherein said continuous filament yarn is a polyester continuous filament yarn and wherein said spreadability factor is not greater than about 9.
Claim 2
Dependent Claim
26 words
The product of claim 1 wherein said continuous filament yarn is nylon continuous filament yarn and wherein said spreadability factor is not greater than about 11.
Claim 3
Dependent Claim
19 words
The product of claim 1 wherein said continuous filament yarn has a coherency factor of from 20 to 150.
Claim 4
Dependent Claim
105 words
A process for the preparation of continuous filament yarn fabric selected from the group consisting of knitted fabrics and woven fabrics, said yarn being prepared by cohering a substantially zero-twist yarn bundle by continuously feeding the yarn bundle under a positive tension through a fluid zone having at least two fluid streams, one of said fluid streams causing the peripheral filaments on one side of said yarn bundle to be twisted over the bundle and the second of said fluid streams substantially reversing continuously the twist of the previously twisted peripheral filaments so as to produce a cohered yarn having a spreadability of about 5.
Claim 5
Dependent Claim
24 words
The process of claim 5 wherein said cohering is conducted so as to produce a coherency factor of from about 40 to about 100.
Claim 6
Dependent Claim
16 words
The process of claim 5 wherein said substantially zero-twist yarn bundle is a nylon yarN bundle.
Claim 7
Dependent Claim
16 words
The process of claim 5 wherein said substantially zero-twist yarn bundle is a polyester yarn bundle.
