Textiles can be promising next‐generation wearable thermal management systems by exhibiting tunable infrared emissivity for dual‐mode control of cooling/warming, yet textiles often exhibit constant infrared emission. Herein, a dynamic thermoregulatory textile is woven from scalable‐manufactured radiative electrochromic fibers and is easily driven by a low voltage in a manner that results in a modulated emissivity of Δɛ≈0.35. Through a synergistic combination of the spiral outer electrode and electrochemically tunable carbon nanotube layer, excellent electrochemical controllability of the fibers is achieved over 100‐m length within 5s because of the decreased internal resistance with increasing length. As a result, the thermoregulatory textile suppresses substantial temperature variation and ensures excellent temperature regulation within ≈1.6 °C for simulated skin (much better than that of traditional textiles: ≈2.9 °C) under an ambient temperature fluctuation of 11.2 °C. Finally, wearable infrared camouflage and invisible infrared displays are also demonstrated by weaving or embroidering the radiative electrochromic fibers onto clothing. [ABSTRACT FROM AUTHOR]

The article titled "Protein-Engineered Elastin Fibers as Building Blocks for The Textile-Based Assembly of Tissue Equivalents" discusses the development of protein-engineered elastin fibers with customized molecular composition and microstructure. These fibers are autoclavable and do not have any negative effects on their mechanical or biological properties. They can be used to create hierarchically organized structures through textile-based assembly, opening up new possibilities for medical textiles and long-lasting stretch fabrics. The authors of the article are Alicia Fernández-Colino, Ikram El Maachi, Alexander Loewen, Sergio Acosta, Stephan Rütten, J. Carlos Rodríguez-Cabello, Stefan Jockenhoevel.

Native tissues feature unique hierarchical designs, in which fiber units are arranged from the bottom up in anisotropic patterns. The processing of biomaterials into fibers, followed by their textile‐like assembly into complex patterns, is therefore a promising avenue to engineer native‐like tissue replacements. Here it is shown for the first time the fabrication of meter‐long hydrogel fibers prepared from engineered elastin using a microinjection system and exploiting the catalyst‐free click chemistry. Given their similarity to native elastin, the fabricated elastin‐like fibers achieved excellent stretching (500%) and recoiling performance. Moreover, the fabrication scheme is compatible with the implementation of a salt‐leaching gas‐foaming approach, resulting in highly porous elastin‐like fibers (the first of their kind). From the translation perspective, the fibers can be autoclaved, which allows for sterilization and long‐term storage. Human umbilical vein endothelial cells cultured on autoclaved fibers produced a confluent endothelial layer lining the fiber surface, in which the cells became aligned in response to physiological fiber stretching. It is also shown that these functional fibers can be assembled by weaving, braiding and knitting, with various spatial patterns. Overall, the elastin‐like fibers can be used as building blocks for the reconstruction of functional tissues using the principles of textile technology. [ABSTRACT FROM AUTHOR]
