《GB/T 7690.2-2013增强材料 纱线试验方法 第2部分:捻度的测定》由TC245(全国玻璃纤维标准化技术委员会)归口,主管部门为中国建筑材料联合会。
GB/T7690的本部分规定了玻璃纤维、碳纤维、芳纶纤维或其他增强纤维纱线捻度的测定方法。
本方法适用于单纱(一次加捻)、合股纱或缆线(二次或多次加捻)。对于合股纱和缆线,本方法通常仅适用于终捻的测定。
本方法适用于卷绕纱。如果试样为经轴纱(经纱)或从织物中抽取的纱,则测试结果仅作为状态指示。
本方法不适用于定长纤维制品。


Scope

This part of GB/T 7690 specifies the method for measuring the twist of glass fiber, carbon fiber, aramid fiber or other reinforcing fiber yarn. This method is applicable to single yarn (one twist), plied yarn or cable (two or more twists). For plied yarns and cables, this method is generally only applicable to the determination of the final twist. This method is suitable for winding yarn. If the sample is beam yarn (warp yarn) or yarn drawn from the fabric, the test results are for status indication only. This method is not applicable to staple fiber products.
