本文件规定了在国内洗涤后测量机织和针织服装螺旋度或扭矩的程序。 从不同程序获得的结果可能不具有可比性。 本文件的目的不是测量制造的服装的螺旋度，而是测量国内洗涤后的螺旋度。 注:一些织物结构，如牛仔布，在制造过程中可能会有意引入螺旋。由圆形针织机织物制成的服装可能具有固有的横幅对齐不垂直性。

This document specifies procedures to measure the spirality or torque of woven and knitted garments after domestic laundering. The results obtained from different procedures might not be comparable. This document is not intended to measure the spirality of garments as manufactured, but rather the spirality after domestic laundering. NOTE？Some fabric constructions, such as denim, can have spirality intentionally introduced during manufacturing. Garments made of fabrics from circular knitting machines can have inherent nonverticality of wale alignment.
