Abstract
A fabric elastomer composite includes a relatively thin elastomer membrane having a stretchable fabric joined thereto. The composite is thin, lightweight, waterproof but vapor permeable, and stretchable at least 100% in each direction. Various garments such as athletic wear and thermal products may be fabricated which are warm, waterproof and stretchable. Various types of joints are disclosed to assure watertight qualities.
Claims14
A fabric elastomer composite assembly comprising:
- at least two sections of fabric elastic composite joined together by a watertight joint,
- each section of said fabric elastomer composite being composed of a stretchable fabric material joined to a vulcanizable silicone elastomeric membrane layer,
- said elastomeric membrane layer being sufficiently thin to permit passage of water vapor therethrough while preventing flow of water in liquid form therethrough, and
- said watertight joint being formed at least in part by a bond between the elastomeric component of one of said sections being bonded to an elastomeric component of another section of elastomer fabric composite.

A multilayered fabric material comprising:
- at least a separate outer decorative fabric layer,
- a fabric elastomer composite in opposed relation to said decorative fabric layer and forming at lease one inner layer of said multilayered fabric material,
- said fabric elastomer composite including a relatively thin membrane layer of vulcanizable silicone elastomer material,
- a stretchable fabric joined to said membrane layer;
- said composite having an elongation in each direction greater than 50%,
- said composite being impermeable to liquids and permeable to vapors, and
- said membrane having a thickness of between 0.0006 and 0.0020 inches.
