摘　　要：为了拓展纬编衬纬组织在电加热针织服装上的应用,将镀银纱线作为衬纬纱线,均匀衬入纬编针织物中,织造3种不同组织的针织物并进行性能测试与分析。根据测试结果,选用结构最稳定、发热效果良好的空气层衬纬作为加热部位组织结构,设计并织造了一件电加热针织服装,同时进行发热性能测试。结果表明:在实验室温度为(20±2)℃且额定电压为1.0~3.5 V的情况下,电加热针织服装的腹部加热单元的平衡温度由24.9℃逐渐升温至36.9℃;背部加热单元的平衡温度由25℃逐渐升温至35.9℃;腰部加热单元的平衡温度由24.5℃逐渐升温至34.7℃,各加热部位平衡温度均满足人体所需。该研究结果可为衬纬组织在电加热服装中的应用及市场开拓提供理论参考。Electrically heated knitted products can be obtained by direct knitting of conductive yarns.By selecting laid-in yarns or altering the ground weave the weft laid-in stitch can create fabrics with various patterns.Knitted smart garments can be customized based on the weft laid-in stitch.To discuss the application of weft laid-in stitch to electrically heated knitted garments the silver-plated yarn is used as a laid-in yarns to produce electrically heated elements.Silver-plated yarn is incorporated into the weft-knitted fabric with polyester ground yarn at a ratio of 1∶2.Three types of weft laid-in knitted fabrics with different ground structures are produced plain laid-in stitch rib laid-in stitch and air-layer laid-in stitch.Analyze the fabric organization.The structure of laid-in stitch fabric is slightly tight.But the fabric is skewed severely and there are some curls on the top and bottom sides.Weft inlay stitch fabric is looser than the weft plain knit.The upper and lower edges of the fabric produce a slight curl.The air-layer laid-in stitch fabric has a tight flat and aesthetically pleasing structure with no curling on the sides.The results of fabric electrical heating performance testing and analysis high heating efficiency with 3 different fabric organizational structures.Under the same power output the plain laid-in stitch fabric shows the best heating performance while the rib laid-in stitch fabric performs the worst among the three.Based on comprehensive test results the air-layer laid-in stitch with the most stable structure and excellent heating effect is selected for use as the heating element in electrically heated knitted garments.It is used as the heating part element of the electrically heated knitted garment.Design and knit an electrically heated knitted garment in conjunction with clothing pattern design.Test the thermal stability of the heating unit in different parts.The results indicate that at lower voltages the heating units exhibit greater resistance to change.At a rated voltage of 1.0
