Patent number: 10829872Abstract: A composite fabric having self-regulating Infrared emissivity includes meta fibers formed with optical nanostructures and an environment (temperature and/or moisture) responsive mechanism configured to adjust a relative disposition between the optical structures to control the electromagnetic coupling therebetween, thus regulating the infrared emissivity of the composite fabric to maintain a user of the fabric in a temperature/moisture comfort zone. The environment responsive mechanism may include a temperature responsive polymer layer on the fiber capable of expansion/shrinkage depending on the applied temperature, or a moisture responsive fiber changing its shape depending on the moisture level to affect spacing between the optical nanostructures.Type: GrantFiled: May 19, 2016Date of Patent: November 10, 2020Assignee: University of Maryland, College ParkInventors: Yuhuang Wang, Min Ouyang, Chuanfu Sun, Yongxin Wang, Shangjie Yu

Patent number: 10272640Abstract: Low porosity fibrous materials, articles formed therefrom and processes for their formation. Multiple plies of high tenacity, multifilament elongate bodies are optionally stitched together and pressed as a set without being laminated, adhered or thermally fused to each other. Pressing spreads the component filaments of the elongate bodies, forcing the filaments to occupy spaces between adjacent fibers and thereby reducing porosity of the complete multi-ply material.Type: GrantFiled: September 8, 2016Date of Patent: April 30, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Ashok Bhatnagar, Huy Xuan Nguyen, Lori L. Wagner
