Study on the Increase of Comfort in Ten Fashion Summer Tops Made of Four Kinds of textiles

Research Journal of textile and Apparel 2014年第2期18卷 56-64页

In response to the increasing demands for energy saving and carbon reduction under current global trends, we apply 10 fashion summer tops from Paris and New York made of cotton and CVC fabrics, fabric that has moisture transferring and sweat expulsion abilities, and fabric with moisture transferring and sweat expulsion properties that also imparts a cooling sensation in this study. Furthermore, by analyzing the activity of sympathetic and parasympathetic nerves which are measured by a heartbeat variability analyzer, we have obtained the relative comfort results in both the dynamic and static modes while the tested subject is wearing garments made from the 4 types of fabrics. We have tried to bring out the relationship between summer fashion style, fabric type and comfort. The test results indicate that the fabric with moisture transferring and sweat expulsion abilities can greatly increase the comfort of the garment and the comfort will be further increased if the fabric adds nano mineral-powder that imparts a cooling sensation for further moisture transferring and sweat expulsion. Finally, less coverage and stress on the top part (neck, shoulders and upper back) of the human body can reduce induced pressure and increase the relative comfort. © 2014 Emerald Group Publishing Limited.

The lithium aluminum titanium phosphate (LATP)/Polyacrylonitrile (PAN) composite fiber-based membrane were prepared by electrospinning composite solution of LATP and PAN in N, N-dimethylformamide(DMF). The crystallization phase of the LATP particles were characterized by X-ray diffraction(XRD). The electrolyte uptakes of the electrospun LATP/PAN composite fiber-based membranes were also evaluated. In addition, the electrochemical performance of the liquid electrolyte-soaked electrospun LATP/PAN composite fiber-based is also improved after the introduction of LATP particles.

Fiber Society's Spring 2015 Conference, in conjunction with the 2015 International Conference on Advanced Fibers and Polymer Materials: Functional Fibers and textiles

作者： Zhang, Xiangwu Fiber and Polymer Science Program Department of Textile Engineering Chemistry and Science North Carolina State University RaleighNC United States

Centrifugal spinning is a simple and versatile technique for producing nanofibers from various materials. One major application of centrifugal spinning is to produce advanced functional nanofibers for energy storage. Among the various energy storage technologies, supercapacitors have been considered as effective solution to the increasing need for high-power energy storage. Novel centrifugally-spun nanofibers with functional properties can dramatically alter surface reaction rates and charge transport throughout the supercapacitors, causing significant improvement in energy storage efficiency. Here, we present our work on the development of advanced functional nanofibers and the integration of these materials into advanced supercapacitors to achieve high system performance.

textiles for military clothing face a complex set of challenges. They must provide protection, durability and comfort in a wide range of hostile environments. The general requirements of military textiles include damage resistance, comfort, sweat management, cold-weather conditions and the integration of high-tech materials into uniforms. This paper discusses the main concepts regarding the application of textiles in military uses, where the surrounding environments such as desert, jungle or extremely cold areas as well as the nature of the situations involved pose a threat to the soldier's safety. Therefore, the improvement and development of fibrous materials, textile structures and finishing processes can bring new perspectives for saving lives. © 2019 Trans Tech Publications Ltd, Switzerland.
