Purpose and Scope

This test method describes physical, chemical and microscopical techniques for identifying textile fibers used commercially in the United States. Fibers may be examined in raw fiber form or taken from yarn or fabric.

These test methods may be used to identify generic fiber types as defined by the Textile Fibers Products Identification Act and subsequent rules and regulations of the Federal Trade Commission. Quantitative methods for determining percentages in blends of fibers are covered by

AATCC Test Method 20A, Fiber Analysis: Quantitative.

The test methods apply to fibers which are shown below grouped by
