摘要：

为降低高刚度、高模量、低延伸性金属丝纱线的弯曲刚度以便于针织物的编织,分别采用传统的转杯纺纱机和管绞机对不同线密度的镀金钼丝单丝进行加捻,借助三维视频显微镜和纯弯曲试验仪分析了2种加捻工艺及单丝线密度对加捻前后纱线外观形貌以及弯曲刚度的影响。结果表明:与转杯纺得到的金属丝纱线相比,采用管绞机加捻得到的纱线外观紧密均匀且平直光洁,存在较少的残余扭矩,管绞机更适合用于对刚性纱线进行加捻;在纱线线密度相同的条件下,单丝线密度与纱线的弯曲刚度成正比,可通过降低纱线中单丝的线密度来降低纱线的弯曲刚度,从而增加纱线的柔软性使其更易于编织。

Abstract:

In ordert decrease the bending rigidness of metal yarns with high strength, high modulus and low elongation for knitting, metal multifilaments with different fineness were twisted by rotor spinning machine and tubular strander. The morphologies of yarns by different twisting methods were observed, and the bending rigidness of monofilaments and multifilaments were measured. It was concluded that compared with rotor spun metal yarns, the yarns twisted by tubular strander has a better morphology. If a yarn fineness is given, the finer the monofilament is, and the smaller the bending rigidness is. Thus, the rigid yarns can be twisted by tubular strander, and bending rigidness of rigid yarns can be decreased by using finer monofilaments.

Key words: metal yarn, twisting, tubular strander, gold plated molybdenum wire, bending rigidness
