Organization: ASTM
Publication Date: 1 February 2012
Status: active
Page Count: 4
ICS Code (Man-made fibres): 59.060.20
scope:

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.

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.

Three options are provided for preparation of the specimens. Option One (preferred) uses single fibers for the specimens with a low magnification available, Option Two (optional for staple or tow samples) uses fiber chips as the specimens, and Option Three uses projected images of single fibers.

The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are for information only.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
