补充资料：支数
| 支数 count 表示纤维或纱线粗细程度的单位。用纤维或纱线在公定回潮率时单位重量所具有的长度表示。因计算单位制不同，通常分为公制支数和英制支数两种。①公制支数。在公定回潮率时1克重的纤维或纱线所具有的长度（米）。纤维或纱线越细，公制支数越高。麻纤维和毛纱、毛型化纤纯纺、混纺纱线，以及绢纺纱线和苎麻纱线的粗细用公制支数表示。股线的公支制数，用组成股线的单纱的公称支数除以股数表示。②英制支数。在公定回潮率时0.4536千克的纱线所具有的长度绞数（棉纱线每绞长768米）。纱线越细，英制支数越高。这种表示方法因计算不便，现在使用的国家日趋减少。股线的英制支数表示方法与公制支数相仿。除上述两种表示方法外，国际上还广泛采用特克斯和旦两种单位。特克斯（Tex）简称特，又称号数，用1000米长的纤维或纱线在公定回潮率时的重量（克）表示。 |
