摘要：

为开发可加热纬编针织服装，采用衬纬方式将导电丝织入针织物中，并对其电热性能进行测试和分析。分别将单根、2根、3根镀银长丝和单根不锈钢长丝衬入到针织物中，测试导电纱线的最大负载电流、织物的热稳定性、织物的电热升温特性和表面温度的均匀性。结果显示：不锈钢长丝的最大负载电流最大，其次是3根镀银长丝的；通电后，衬入镀银长丝织物的电阻变化率较小；衬入3根镀银长丝的织物通电后温度升高的速度较快，且达到稳定工作的温度较高；测试范围内，织物的稳定温升与输入电压成正比；织物表面温度均匀性较好。认为可选择衬入3根镀银长丝的纬编织物制作可加热针织服装。

Abstract:

To develop heatable weft knitted garment, conductive filaments were knitted into knitted fabric by weft inlaying, furthermore, its electric heating performance was tested and analyzed. A silver-plated filament, two silver-plated filaments, three silver-plated filaments and a stainless steel filament were inlaid to the knitted fabric, respectively, and the maximum load current of the conductive yarn, the heat stability of the fabric, its electric heating warming characteristics and the uniformity of its surface temperature were tested. The results show that the maximum load current of the stainless steel filament is highest, and that of the three silver-plated filaments is the second; after being electrified, the resistance change of the fabric with inlaid silver-plated filament is relatively small; the temperature rise speed of fabric inlaid with three silver-plated filaments is relatively high and its stable operating temperature is relatively high; in the testing range, the stable temperature rise of the fabric is proportional to its input voltage; and the uniformity of the surface temperature of the fabrics are better. It is concluded that weft knitted fabric inlaid with three silver-plated filaments could be used to manufacture heatable knitted garment.

Key words: weft knitted fabric, electric heating performance, silver-plated filament, stainless steel filament, weft inlaying
