Abstract: Textiles formed of active and inactive materials are disclosed. The active and inactive materials are knit together so that the textile exhibits a predetermined shape change upon exposure to an external stimulus, such as heat or moisture.

Abstract: Knit textile structures are formed of a yarn made of composite fibers, which is an active material within the knit structure that transforms in response to a change in temperature. In combination with non-active fibers and performative knit structure, this contraction can enable changes in the fabric that are adaptive to changes in environmental conditions during wear.

Abstract: Apparatus, systems, and methods are described for a heating system incorporated into a garment. An example garment includes: a heating element disposed proximate an internal surface of the garment; a temperature sensor configured to measure a temperature outside of the garment; a motion sensor configured to measure movement of the garment; and a controller configured to adjust power to the heating element based on signals received from the temperature sensor and the motion sensor.

Abstract: A sock having a low pressure area made of a first knit density and at least one high pressure area made of a variable knit density portion. The variable knit density has portions that are made of a second knit density greater than the first knit density. The at least one variable knit density portion is arranged transverse to an orientation of major strain. A sock may also have hydrophobic fibers located substantially across a surface of the sock adapted to be adjacent to skin when worn and hydrophilic fibers located substantially across the hydrophobic fibers and extending therefrom to form loop structures adapted for wicking moisture away from the hydrophobic fibers.

Abstract: The invention relates to a performance dress shirt and methods of manufacture. In embodiments, the performance dress shirt includes a front portion made of a first material, a back portion having outer sections made of a first material and an inner section made of a different second material coupled to the front portion and two sleeves made of the first material coupled substantially opposite each other to the front portion and the back portion. In other embodiments, the performance dress shirt has a front portion, a back portion coupled to the first portion, and two sleeves coupled substantially opposite each other to the front portion and the back portion. Each of the front portion, the back portion, and the sleeves have an interior layer and an exterior layer, with the interior layer having a smaller pore structure than the exterior layer.
