远红外导电布的制备及其性能

Preparation and Properties of Infrared Conductive Cotton

研究制备了一种新型导电棉布,制备工艺简单、成本低、发热性好,用于保暖保健具有良好的效果。导电棉布采用导电剂、远红外剂和黏合剂P为原料制备而成。设计了以搅拌、浸润时间及导电剂、黏合剂质量比为因素的正交优化实验,得到了优化后导电棉布相对电阻值最低的实验条件。在正交优化后的最适宜反应条件下,考察了远红外剂(二氧化钛)对导电布远红外效应的影响,结果表明当远红外剂质量分数为7.14%时,远红外效应最好。

A novel strategy for preparation technology of conductive cotton was proposed and verified by control experiments. The strategy is to coat a slurry with specific composition of conductive agent,far-infrared agents and adhesives P onto the cotton and then conductive cotton was achieved after a considerate drying process. Firstly,the effect of adding amount of conductive agent to slurry were investigated and a orthogonal experiment was designed and carried on with stirring time,wetting time and the mass ratio of the conductive agent to a binder being taken as affecting factors. An optimum reaction parameters were acquired,under which the electricity resistance of as-prepared conductive fabric was significantly reduced. Secondly,the role of far-infrared agent(titanium dioxide) on far-infrared radiation effect of conductive fabric was investigated under acquired optimum conditions. The best far-infrared effect was achieved at a mass fraction of 7. 14% for titanium dioxide. It can be expected the technique developed in this paper would be a simple,cost competitive to prepare functional fabric for health care application.
