摘要
为探究针织物组织结构对电加热性能的影响,选用镀银纱线编织6种组织结构不同(纬平针组织、1+1罗纹组织、1+1双反面组织、双罗纹组织、1+3毛圈组织、1+1假罗纹组织织物),但规格大小相同的针织物,并测试分析不同组织结构针织物间的最大负载电流、升温速度、热均匀度以及热稳定性能的差异。研究发现不同组织结构对针织物电热性能存在影响,其中双罗纹织物在施加0.9V电压后在7min内从室温上升至33.5℃,稳态温度达37.3℃,表面温度分布系数在30min内低于0.017,电阻变化率在90 min内低于3.3%,升温速率快、热均匀度高、产热稳定,是用于编织电热针织物较为合适的组织结构。研究结果为针织电加热服的设计开发提供了一定的参考。
In order to investigate the influence of knitted fabric structures on the electric heating performance,six kinds of knited fabrics with different patterns(plain,1×1 rib,1×l purl,interlock,1×3 terry,1×1 mock rib)with the same sizes were knitted with silver-plated yarns,the maximum load current,heating speed,thermal uniformity and thermal stability energy between knitted fabrics with different structures were tested and analyzed.It is found that different structures have influence on the electro-thermal performance of knitted fabrics,among which the interlock fabric rises from room temperature to 33.5℃ within 7 minutes after applying 0.9 V of voltage,and the steady-state temperature reaches 37.3℃,the surface temperature distribution coefficient is lower than 0.017 within 30 minutes,the resistance change rate is lower than 3.3%within 90 minutes,the heating rate is fast,the thermal uniformity is high,and the heat production is stable,which is proved to be a more suitable structure for kntting electric heating knitted fabric.The results of the study provide a certain reference for the design and development of knitted electric heating garments.
