Moisture Sensitive Smart Yarns and Textiles from Self‐Balanced Silk Fiber Muscles

Smart textiles that sense, interact, and adapt to environmental stimuli have provided exciting new opportunities for a variety of applications. However, current advances have largely remained at the research stage due to the high cost, complexity of manufacturing, and uncomfortableness of environment‐sensitive materials. In contrast, natural textile materials are more attractive for smart textiles due to their merits in terms of low cost and comfortability. Here, water fog and humidity‐driven torsional and tensile actuation of thermally set twisted, coiled, plied silk fibers, and weave textiles from these silk fibers are reported. When exposed to water fog, the torsional silk fiber provides a fully reversible torsional stroke of 547° mm^?1. Coiled‐and‐thermoset silk yarns provide a 70% contraction when the relative humidity is changed from 20% to 80%. Such an excellent actuation behavior originates from water absorption‐induced loss of hydrogen bonds within the silk proteins and the associated structural transformation, which are corroborated by atomistic and macroscopic characterization of silk and molecular dynamics simulations. With its large abundance, cost‐effectiveness, and comfortability for wearing, the silk muscles will open up additional possibilities in industrial applications, such as smart textiles and soft robotics.

Unexpected Luxury: Wild Silk Textile Production among the Yoruba of Nigeria

Abstract

Mulberry silk produced in China is the type most recognized and used in silk garments. There are at least seven additional silk fiber sources. The Yoruba are a large ethnic group in Nigeria who use native silk that they call sányán from the Anaphe moth as one of their most prized fiber resources. Throughout colonial and post-colonial history, both Nigerians and others investigated methods for domesticating wild silk production. Yoruba strip cloth, called aso-òkè includes three main categories: sányán, etù and alãrì, each appropriate for persons of high social standing and for important occasions, displaying cultural significance. Cotton becomes used as a substitute for expensive silk yarns, being dyed the traditional color of the silk fabrics. To the Yoruba aesthetic, the purpose of something is more important than its actual form. Even as weavers now produce the traditionally sányán cloths with substitute fibers, the cloth's glory remains.

丝线卷绕运动折回曲线数值解法

导丝器的运动规律受导丝传动机构制约；而卷绕点又滞后于导丝点的运动，因此，这两因素影响卷装上的卷绕曲线的形态，造成卷绕曲线折回段的数学模型复杂。本文分析空间凸轮机构导丝时自由丝段对卷绕折回曲线形成的影响。并提出一种对于我种状态导丝运动的折回曲线的通用的简捷的数值方法。
