摘要:
The invention provides for a method of manufacturing artificial turf (1400). The method comprises the step of creating (100) a polymer mixture (400, 500, 600), wherein the polymer mixture comprises a stabilizing polymer (402), a bulk polymer (404), a flame retardant polymer combination, and a compatibilizer (406). The stabilizing polymer polymer and the bulk polymer are immiscible. The stabilizing polymer comprises fibers surrounded by the compatibilizer within the bulk polymer. The stabilizing polymer is aramid. The flame retardant polymer combination is a mixture of triazin and melamine. The method further comprises the step of extruding (102) the polymer mixture into a monofilament (706). The method further comprises the step of quenching (104) the monofilament. The method further comprises the step of reheating (106) the monofilament. The method further comprises the step of stretching (108) the reheated monofilament (706') to align the fibers relative to each other and to form the monofilament into an artificial turf fiber.The method further comprises the step of incorporating (110) the artificial turf fiber into an artificial turf backing (1406).

摘要:
Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.
