Abstract

Composite yarns having exceptional cut resistance are made by combining at least two different kinds of fiber, as follows: (a) a high modulus fiber having a modulus greater than about 200 gpd as measured by ASTM Test Method D-3822; and (b) a particle-filled fiber, which is made from a semi-crystalline polymer, such as poly(ethylene terephthalate), and hard particles having a Mohs Hardness Value greater than about 3.
