1.1 ,This test method covers the determination of the crimp frequency of manufactured staple fibers. This test method is applicable to all crimped staple fibers provided the crimp can be viewed two-dimensionally as a sine-wave configuration.
1.1.1 ,It should be recognized that yarn manufacturing processes or treatments to manufactured yarns can influence or modify crimp in fiber. Hence, the value for crimp of fibers taken from spun yarns may be different than that of the same fiber prior to the manufacturing or treatment processes.
