AI Technical Summary

Benefits of technology

The present invention is about the creation and use of fabric made from a special material called shape memory material (SMM). This material is highly flexible and strong, and can change its shape based on temperature changes. SMM filaments are also stronger than polymer monofilaments, so they can be woven or knit. The invention is about using SMM filaments to create strong, flexible, and resilient spacer fabrics that can be used for protective padding. These fabrics absorb and dampen impact without causing permanent deformation or loss of resiliency. Overall, SMM spacer fabrics offer a unique solution for protective padding applications.

Problems solved by technology

However, polymer spacer fabrics suffer from weakness, creep, fatigue degradation and permanent compression set.

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...
