Latest Patents

Gérard Lagarrigue holds a patent for a "Method for producing polyamide monofilaments and monofilament for technical fabric." This process is designed to produce vacuole-free coarse polyamide monofilaments with diameters ranging from 0.8 to 1.5 mm. The method involves preparing a mixture that includes 75 to 85 percent by weight polyamide 66 and 25 to 5 percent by weight polyamide 6. Following the preparation, the mixture is extruded and spun to form crude monofilaments, which are then cooled in a liquid. Notably, the addition of at least 30 ppm of copper to the mixture prior to extruding and spinning results in heat-protected coarse monofilaments.
