“…In Figure 4a, it has been noted that the fabricated samples have higher air permeability than the 3‐ply mask, uncovering the fact that there is a notable impact of highly porous knit structure (Table S1, Supporting Information) on as‐prepared WR thermophysiological comfort. Previous researches [ 27a ] further confirm fabric can significantly enhance air permeability with high pore size. Besides air permeability, the dry heat loss in terms of heat conduction has also been performed.…”

COVID‐19 pandemic recently has a great impact on personalized protection and healthcare, especially in the area of the respiratory mask. However, due to the complex relationship between filtration performance and thermal management, there is a lack of investigation considering both characters in respirators. Woolen knitwears are recently well acknowledged as textiles for both hot and cold because of their superior water‐actuated shape memory performance. To incorporate protective function against bacteria, virus, microdroplet, and particulate matter, melt‐blown polypropylene can be introduced as a barrier layer. Herein, a robust and sustainable bio‐based woolen respirator with the superior ability of thermal management is prepared using simple knitting and melt‐blown technology. The as‐prepared respirators provide excellent protection from airborne particulate along with the high level of comfort, compared with a commercial mask. Moreover, it exhibits a high rating during wear trial. This provides a new insight to develop high quality sustainable respiratory mask with an excellent comfort performance from functional biomaterials.

“…It has been reported that heat conductivity, infrared transmission and air permeability are three main methods of thermal management of textiles. 24 Therefore, the maximum of the infrared transmission IR max and efficiency of infrared transmission S IR expressing the infrared transmission performance were defined. These two indices are measured by the infrared detector array when a fabric covers the heat source but does not contact with the heat source on the moving slab.…”

Tactile sensations of fabrics are the primary property determining the wearing comfort of clothing; however, comprehensive evaluation of the fabric tactile property by considering the flexural buckling of fabrics under high curvature, hysteresis performance and thermal property has not been fully studied, leading to a clear gap between the existing measurement methods and application requirements. Herein, a simultaneous-integrated testing method, namely the Touch Sensation Tester for Fabrics (TST-F) was introduced to evaluate the mechanical–thermal sensory properties of woven fabrics. The introduced instrument used one device with a single mechanical sensor to test various mechanical properties by constructing different deformations of fabrics, and the thermal property was simultaneously measured using an infrared detector array, achieving an efficient characterization of the mechanical–thermal sensation properties of textiles. The measurement capacity and repeatability of the TST-F were statistically analyzed; the measurement indices and their relation with fabric mechanical–thermal sensation properties were also exhibited. Results showed that the TST-F was promising to characterize fabric touch sensations in terms of bending stiffness, compression softness with wrinkling, stretching tightness and thermal comfort by considering the infrared transmission and heat conductivity of textiles.

Benefiting from inherent lightweight, flexibility, and good adaptability to human body, functional textiles are attracting tremendous attention to cope with wearable issues in sustainable applications around human beings. In this feature article, a comprehensive and thoughtful review is proposed regarding research activities of functional textiles with smart properties. Specifically, a brief exposition of highlighting the significance and rising demands of novel textiles throughout the human society is begun. Next, a systematic review is provided about the fabrication of functional textiles from 1D spinning, 2D modification, and 3D construction, their diverse functionality as well as sustainable applications, showing a clear picture of evolved textiles to the readers. How to engineer the compositions, structures, and properties of functional textiles is elaborated to achieve different smart properties. All these tunable, upgraded, and versatile properties make the developed textiles well suited for extensive applications ranging from environmental monitoring or freshwater access to personal protection and wearable power supply. Finally, a simple summary and critical analysis is drawn, with emphasis on the insight into remaining challenges and future directions. With worldwide efforts, advance and breakthrough in textile functionalization expounded in this review will promote the revolution of smart textiles for intelligence era.
