自发热针织手套的结构与性能

Structures and Properties of Self-Heating Knitted Gloves

为满足低温环境工作及热舒适性的要求,针对人体手部易冷问题,采用镀银导电纤维作为发热元件,在全自动手套编织机上通过添纱、衬垫、衬纬的方式,将镀银导电纤维织入手套手掌部位,并配以适当的电池组成闭合电路,进行导电发热。测试不同组织结构手套的发热性能。结果表明,衬纬编织方式便于形成电路,且并联衬纬方式优于串联方式;实验初期手套温度与输入功率呈线性增加,之后达到稳定状态,表面温度分布较为均匀,从而起到保暖及改善人体手部温度的作用。

In order to meet the requirements for human thermal comfortability and working in low temperature environment , self-heating gloves were integral knitted via automatic Shima Seiki knitting machine. Together with a suitable cell, electric heat conduction silver-coated fibers were knitted into palm part of gloves by fleecy, plating and inlay to make a closed circuit. The heating properties of gloves with different knitting structures and connection ways were tested and analyzed. It was found that the inlay structure was more convenient to form a circuit. The heating effect of parallel circuit was better than that series one. The temperature of self-heating gloves in parallel connection increased with input powerand could reach a stable value . The distribution of temperature on the surface of palms part was uniform, which could help hands keeping warm to a certain extent.
