CONFORMABLE MICROPOROUS FIBRE AND WOVEN FABRICS CONTAINING SAME Russian patent published in 2018 - IPC D03D1/00 

FIELD: woven products.

SUBSTANCE: expanded polytetrafluoroethylene (ePTFE) monofilament fibres and woven fabrics formed from the ePTFE fibres are provided. Said ePTFE fibers have a substantially rectangular configuration, a density less than about 1.0 g/cm³, and an aspect ratio greater than 15. Additionally, the ePTFE fibres are microporous and have a node and fibril structure. Said ePTFE fiber may be woven into a fabric without first twisting the fibre. Polymer membrane and/or a textile may be laminated to the woven fabric to produce a laminated article. ePTFE woven fabric simultaneously possesses high moisture vapour transmission (highly breathable) and high water entry pressure (water resistant). Treatments may be provided to the surface of the ePTFE fibre and/or the woven fabric to impart one or more desired functionality, such as, for example, oleophobicity.

EFFECT: woven fabric is quiet, soft, and drapable, making it especially suitable for use in garments, gloves and footwear applications.
