棉秆皮纱线材料的丝光处理

棉秆皮纤维是一种新型天然纤维素纤维材料,以棉秆皮纱线材料为主要对象,研究了丝光处理工艺条件对纱线材料性能的影响。实验结果表明:增加碱液质量浓度、处理时间与温度,纱线材料失重率、缩水率增大,而拉伸断裂强度先增大再减小;棉秆皮纱线材料适合的丝光处理条件为NaOH质量浓度250g/L,时间200s,温度20℃。该工艺条件下,棉秆皮纱线材料结晶度减小,且随着纱线材料中棉秆皮纤维质量分数增加,纱线材料的钡值增大,强度减小。

络筒车间的温湿度测量与纱线材料值修正

针对络筒车间的温湿度变化导致纱线含水量不稳定,使同一种纱线在不同温湿度下具有不同材料值这一现象,介绍了一种在清纱器上配接的温湿度测量装置,采用低成本数字化传感器SHT71芯片对络筒车间温湿度进行实时测量,简要说明其电路方案,并指出纱线材料值的修正方法;得出此技术的应用提高了电容式清纱器的环境适应性,为清纱器在络筒车间的准确运行提供了保障的结论。

The Development of a New Anti-electromagnetic Radiation Fabric

By the study of electromagnetic shielding principle,we have designed some new style fabrics for anti-electromagnetic radiation through the research of raw materials and fabric texture,and solved the key technical problems such as the manufacture of composite yarn which composed of stainless steel filament and cotton yarn.As a newly developed high technology material,the new style anti-electromagnetic radiation fabric was woven by the special yarn composed of stainless filament and nature fiber.The new fabric overcomes the defect in the production and service of the shielding fabrics at present and satisfies the people's requirement the routine job and life.With further improvement,it can be widely used in aviation,navigation and military project,underground project and so on.
