Abstract
A welded yarn may have a cross section about a plane that is perpendicular to the longitudinal axis of the welded yarn wherein the cross-sectional area is comprised of two or more distinct portions, wherein the degree of welding in each portion is different, which May also result in different fiber volume ratios compared to raw yarn substrates.
Claims20
A welded yarn comprising:
- a) a first portion along a radial cross-section of said welded yarn, wherein said welded yarn is comprised of a plurality of fibers;
- b) a second portion along said radial cross-section of said welded yarn, wherein said second portion is positioned interiorly with respect to said first portion, wherein said first portion constitutes between 5% and 85% of an area of said radial cross-section of said welded yarn wherein a degree of welding in said first portion is distinct from and less than a second degree of welding in said second portion, wherein said plurality of fibers in both said first portion and said second portion are cellulose fibers, and wherein said welded yarn is made from a conventional cotton yarn in a single continuous process of applying a process solvent to said conventional cotton yarn and removing said process solvent after a duration of time.
A welded yarn comprising:
- a) a first portion along a radial cross-section of said welded yarn, wherein said welded yarn is comprised of a plurality of fibers;
- b) a second portion along said radial cross-section of said welded yarn, wherein said second portion is positioned interiorly with respect to said first portion, wherein said first portion constitutes between 5% and 85% of an area of said radial cross-section of said welded yarn, wherein a degree of welding in said first portion is distinct from and less than a second degree of welding in said second portion, and wherein said welded yarn is formed in a single process by subjecting a conventional ring spun cotton yarn to an ionic liquid-based process solvent.
