Benefits of technology

[0018]The present invention relates to the provision and use of spacer fabrics which utilize a shape memory material (SMM), e.g., Nitinol or a titanium near-beta alloy, as a filament for constructing the spacer fabric (e.g., as a filament for constructing the top fabric layer, the bottom fabric layer and the intervening fabric layer that interconnects the top fabric layer to the bottom fabric layer). See FIG. 6. SMMs, unlike other metallic filaments, are highly flexible and kink resistant, allowing them to be woven or knit. SMM filaments are substantially stronger than polymer monofilaments, and are not susceptible to deleterious creep and fatigue which often shortens the life of polymeric materials. Spacer fabrics created from shape memory materials (SMM) can be designed to be strong, superelastic, exhibiting

Embodiment Construction

[0049]In accordance with the present invention, there is provided novel protective padding utilizing superelastic three-dimensional spacer fabric comprising shape memory materials (SMMs) such as Nitinol. The superelastic vertical fibers of the spacer fabric (i.e., the interconnecting yarns which extend between the top fabric layer and the bottom fabric layer) create the desired elastic response in the spacer fabric when compressed by an outside force and allowed to shape recover, which addresses the deficiencies of the prior art.

[0050]See FIG. 7, which shows a three-dimensional knit spacer fabric 105 includes a first fabric layer 110, a second fabric layer 115 and yarns 120 interconnecting the two layers 110, 115, wherein some of the yarns 120 interconnecting the two layers 110, 115 are substantially perpendicular to the first and second fabric layers 110, 115, while the remaining interconnecting yarns 120 are disposed at an acute angle between the two layers 110, 115, and further w...

Abstract

Protective padding comprising:
    • a spacer fabric comprising a first fabric layer, a second fabric layer, and a plurality of interconnecting filaments extending between said first fabric layer and said second fabric layer;
    • wherein at least one of said first fabric layer, said second fabric layer and said plurality of interconnecting filaments comprise a shape memory material.
