Forcespinning of fibers and filaments

This invention describes a specialized fabric made from very fine, tangled fibers, specifically PTFE or polyurethane-based polymers. Designed for footwear and outdoor gear, this fabric has precise characteristics like tiny pores, a thin structure, and fibers less than 1000 nanometers in diameter, allowing for properties like breathability and water resistance.

Why it matters: Since 2014, advancements in forcespinning and other nanofiber production technologies may have significantly improved the efficiency and scalability of creating fabrics with such precise fiber diameters and web structures. This could make the specialized manufacturing process more viable now.
