A Multi-model,Large-range Flexible Strain Sensor Based on Carbonized Silk Habotai for Human Health Monitoring

In recent years,flexible strain sensors have received considerable attention owing to their excellent flexibility and multifunctionality.However,it is still a great challenge for them to accurately monitor multi-model deformations with high sensitivity and linearity.In this study,the industrial insulating silk habotai was successfully converted into carbonized silk habotai(CSH)for use in strain sensors.A strain sensor created using CSH exhibited excellent sensing performance under multi-model deformations,including stretching,twist and bending.The maximum tensile strain was 434%.The gauge factors were 14.6 in the wide tensile range of 0%–400%with a high linearity of 0.959.In addition,the CSH strain sensor exhibited an extremely fast response time(110 ms)and could accurately detect bending(0°–180°)and torsional(0°–180°)strains.High durability and repeatability were observed for the multi-model strains.Finally,a new type of smart pillow was developed to accurately record head movement and breathing during sleep.The sensor may also be used for auxiliary training in table tennis.The proposed CSH strain sensor has shown great potential for applications in smart devices and human-machine interactions.

真丝电力纺缝扎续缸染色工艺

电力纺纬向工艺的商讨——也谈纺类织物的纬丝不浸泡

罗纹档是纺类织物纬向方面的主要病疵之一。通过试验论证,认为厂丝纺类产品采用经泡纬不泡的生产工艺,不仅能大大降低罗纹档的产生,且能缩短用丝周转期,减少工序,为企业增加效益。

涤丝纺冷转移印花

对涤丝纺面料进行冷转移印花,研究了转印纸、分散染料墨水、前处理工艺、转印工艺和水洗工艺对细旦涤纶织物冷转移印花效果的影响。结果表明,冷转移印花技术可以解决细旦高密涤纶面料的印花问题,且具有优良的染色牢度。

特种车辆罐内保洁装置的设计

特种车辆其罐内经特殊方法清洗及处理后,为防止空气中的灰尘、杂物及仪器调试时产生的污染,需要在封罐前用无水乙醇进行保洁处理。保洁作业是容器与介质接触前的最后一道环节,对介质安全起到致命影响。若保洁工作不到位,引发介质安全问题,后果往往非常严重。特种车辆是一种手持式多功能清洁装置,它通过除尘、喷洗、擦拭、回收等功能,能在不产生二次污染的情况下有效对罐内进行保洁,从而达到介质安全。
