ISO 18067:2015规定了合成长丝纱线干热空气收缩率（后处理）的测定方法、绞纱法和单端法。skein方法提供了两种测量形式，分别为手动和自动类型。单端法通过手动测量得出结果。 如有争议，应使用手动测量程序。 如果这些方法不适用，相关方可商定相应的试验方法。 ISO 18067:2015适用于线密度小于3000 dtex的合成长丝纱线。 ISO 18067:2015不适用于部分取向纱线。

ISO 18067:2015 specifies methods for the determination of dry-hot air shrinkage (after treatment) of synthetic filament yarns, skein method and single-end method. The skein method provides two forms of measurement which are of manual and automatic types. The single-end method gives the result by manual measurement. In case of dispute, manual measurement procedure is to be used. If these methods are not applicable, the corresponding test methods may be agreed between interested parties. ISO 18067:2015 is applicable to synthetic filament yarns of linear density less than 3 000 dtex. ISO 18067:2015 is not applicable to partially oriented yarns.
