ABSTRACT:
Novel products are described which possess a capability of transmitting air and moisture vapor, are waterproof, and have fabric-like aesthetic properties. These products may have applications such as rainwear material, tent material, garment liners, and shoe liners. These products may be made by spray spinning filamentary polymer material onto open-celled polymer film, or onto non-cellular elastic polymer film with the additional steps of stretching and heat setting creating a stable open-celled structure in the film portion of the product. Subsequent calendering of the product may further improve its fabric-like aesthetic properties.
