Stretchable nonwoven fabric, method of manufacturing, and products made thereof

This invention describes a special fabric made from incredibly thin, hair-like fibers, less than a thousandth of a millimeter across. This fabric is designed to stretch and recover, block liquid water while letting sweat escape, and conform to body parts. The claims specifically narrow this fabric to be made of nanofibers for use in high-performance clothing.

Why it matters: Since 2009, industrial-scale nanofiber production methods like electrospinning and meltblowing have significantly advanced, potentially lowering manufacturing costs and increasing throughput. This could make the specialized fabric described more commercially viable for high-performance apparel and personal care products.

Status: ExpiredProtection ended and was never renewed
How hard to build: SpecializedNanofiber electrospinning or meltblowing equipment.
