Claim Text:
1. A spun yarn comprising natural fibers and high strength polyethylene staple fibers, wherein the high strength polyethylene staple fibers have an initial modulus of at least 40 GPa and a tensile strength of at least 1.4 GPa, and wherein the yarn comprises between 1 and 4% by weight of the high strength polyethylene staple fibers, and wherein the yarn is a homogenous mixture of the natural fibers and the high strength polyethylene fibers which does not exhibit a gradient of the high strength polyethylene staple fibers across a cross-section of the yarn orthogonal to a machine direction of the yarn such that a ratio of highest and lowest weight percentages of the high strength polyethylene staple fibers across the cross-section of the yarn orthogonal to the machine direction of the yarn is at most 2.
