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.
Claims31
A welded yarn comprising:
- a. a first portion along a cross-section of said yarn;
- b. a second portion along said cross-section of said yarn, wherein a fiber volume ratio of said first portion is different than a fiber volume ratio of said second portion, and
- wherein said first portion is welded.
A welded yarn comprising:
- a. a first portion extending inward from an outer periphery of said welded yarn;
- b. a second portion extending outward from a geometric center of said welded yarn,
- wherein said second portion terminates at an inward boundary of said first portion,
- wherein a degree of welding of said first portion is different than a degree of welding of said second portion.
A yarn comprising:
- a. a first portion extending inward from an outer periphery of said yarn, wherein an amount by which said first portion extends inward from said outer periphery is substantially uniform about said outer periphery;
- b. a second portion outward from a geometric center of said yarn, wherein said second portion terminates at an inward boundary of said first portion, wherein a fiber volume ratio of said first portion is different than a fiber volume ratio of said second portion.
A yarn characterized in that a cross-sectional area of said yarn increases by less than 100 percent when said yarn is cut along a plane oriented perpendicularly with respect to a longitudinal axis of said welded yarn, and wherein a chemical composition of said yarn is uniform throughout said yarn.
The yarn according to claim 31 wherein said cross-sectional area of said yarn increases by less than 50 percent when said yarn is cut along said plane.
The yarn according to claim 31 wherein said chemical composition is further defined as a biopolymer.
