Abstract:
A breathable membrane, resistive to transport of liquid water, and having limited distension in response to a force, the membrane comprising:a layer of breathable material resistive to transport of liquid water; anda reinforcing matrix of filaments extending linearly in plural directions within a two-dimensional geometric pattern along said layer of breathable material to inhibit said distension;wherein a first plurality of said filaments intersect a second plurality of said filaments to form cells within said matrix, a minimum cross-sectional dimension of an individual one of said cells being greater by at least approximately an order of magnitude than a diameter of one of said filaments to provide open areas of said layer of breathable material free from obstruction by said filaments; andthe filaments in at least one of said first and said second plurality of filaments have a range of elasticity with a limitation on extension of each of the respective filaments.
