Abstract
A monofilament fiber as described made from a polyoxymethylene polymer. Polyoxymethylene polymer can be blended with an abrasion additive in order to improve abrasion resistance. The polyoxymethylene polymer may be combined with a thermoplastic elastomer and a coupling agent. The fiber can be used as fishing line, as bristles for a brushing device, or the like.
Claims29
A monofilament fiber made from a polymer composition comprising a polyoxymethylene polymer blended with an abrasion additive, the abrasion additive comprising a polymer that has been meltblended with the polyoxymethylene polymer, the abrasion additive being present in an amount from about 0.05% to about 5% by weight, the monofilament fiber having an abrasion resistance of at least about 5,000 cycles prior to failure according to the wire-on-yarn test.
A monofilament fiber made from polymer composition comprising a polyoxymethylene polymer, a thermoplastic elastomer, and a coupling agent, the thermoplastic elastomer being present in the polymer composition in an amount from about 0.5% by weight to less than 30% by weight, and the coupling agent being present in the polymer composition in an amount form 0.5% by weight to less than 1.0% by weight.
A monofilament fiber made from a polymer composition comprising a polyoxymethylene polymer blended with an abrasion additive, the abrasion additive comprising a polymer that has been meltblended with the polyoxymethylene polymer, the abrasion additive being present in an amount from about 0.05% to about 5% by weight, the monofilament fiber having an abrasion resistance according to a yarn on yarn test of greater than about 90% retained tensile strength.
