Abstract: Active fabrics typically include a plurality of fibers. At least one of the fibers exhibits a change in length or width upon exposure to an external stimulus, such as heat, moisture, or light. The active woven materials can exhibit local transformation, such as creating areas that are tighter or more open, or global transformation, such as changing from flat to curled. The effect is a precise and repeatable change in shape upon exposure to an external stimulus. Embodiments can be employed, for example, in sportswear, compression garments, furniture, and interior products.

Abstract: A structure, e.g., a shock absorbing cap, provides additional force or shock abortion between the interior of a traditional safety helmet and the head of the wearer. As a result, there is no need to change the helmets currently in use today. The cap has a first region, which is next to the scalp and is typically made of 100% knitted cotton. A second region is typically made of 100% wool fleece braided fiber bundles or locks that extend alternately in longitudinal and lateral directions. A sufficient number of layers of the knitted cotton bundles is provided to principally fill the gap between the head of each wearer and the interior of the helmet. This layer is the main shock absorbing element. The outermost region is typically made of one or more layers of braided 100% carbon fiber bundles, which run the opposite direction of the last wool lock. This carbon fiber bundle region helps to retain the structure of the cape.
