Abstract: A method of making colored multifilament ultrahigh molecular weight polyolefin yarn, including feeding at least one substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn, coating the substantially untwisted multifilament yarn with a coating composition comprising colorant in a thermoplastic resin carrier, with the coating composition being adhered to the filaments of the multifilament yarn, and heating the multifilament yarn while stretching the yarn without fusing of the filaments of the multifilament yarn. The resultant yarn is a colored multifilament yarn having improved color-fastness. The thermoplastic resin has a lower melting point than the filaments of the multifilament yarn. Preferably, a plurality of the substantially untwisted multifilament ultrahigh molecular weight polyolefin yarns are processed together.

Abstract: A robust process for the continuous preparation of solutions of high molecular weight UHMW PO that is capable of producing strong materials at high production capacity, is conservative of capital and energy requirements, and the articles made therefrom.

Abstract: Colored monofilament ultrahigh molecular weight polyolefin lines, and methods of making such colored lines are disclosed. The colorant can result in a product that provides a visual indication of metered length. When the colorant has a luminescent response to ultraviolet or infrared light, a line can change color based on the environmental conditions to which it is exposed. Methods of making the line can include feeding a substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn; coating the substantially untwisted multifilament yarn with at least one colorant; twisting the coated multifilament yarn; and heating the twisted multifilament yarn to a temperature and for a time sufficient to at least partially fuse adjacent filaments together while stretching the yarn.

Abstract: A method of making colored monofilament ultrahigh molecular weight polyolefin fishing line, comprising the steps of feeding a substantially untwisted multifilament ultrahigh molecular weight polyolefin yarn; coating the substantially untwisted multifilament yarn with a colorant; twisting the coated multifilament yarn; and heating the twisted multifilament yarn to a temperature and for a time sufficient to at least partially fuse adjacent filaments together while stretching the yarn. The resultant product is a colored monofilament fishing line that has improved color-fastness and abrasion resistance.

Abstract: A process for preparing ultra-high molecular weight poly(alpha-olefin) (UHMWPO) multi-filament yarns having improved tensile properties at higher productivity. The process includes drawing a solution yarn, then drawing a gel yarn and then drawing a dry yarn continuously in sequence to form a partially oriented yarn, winding up the partially oriented yarn, unrolling the yarn, drawing the partially oriented yarn to form a highly oriented yarn, cooling the highly oriented yarn under tension and winding up the highly oriented yarn.

Abstract: Methods for preparation of high strength yarns having superior yarn-to-yarn uniformity of denier, tenacity and tensile modulus and uniform unidirectional fibrous sheets. Ballistic composites prepared from these yarns and fibrous sheets have improved uniformity of ballistic resistance. The drawn yarns, fibrous sheets and articles made therefrom are more uniform than the prior art and are useful in applications requiring impact absorption and ballistic resistance, such as body armor, helmets, breast plates, helicopter seats, spall shields; composite sports equipment such as kayaks, canoes, bicycles and boats; and in fishing line, sails, ropes, sutures and fabrics.

Abstract: This invention provides security articles comprising fibers, threads and fiber sections (“dots”) possessing multiple verification characteristics. The fibers possess unique and difficulty duplicated combinations of complex cross-sections, components, and multiple luminescent responses. The many verifiable characteristics of the security fibers, threads and dots provide high levels of protection against fraudulent duplication of articles in which they are incorporated. The manifold security features provide means of tailoring specific identity characteristics for specific use and users.
