Scope

This document describes a method of automatically determining the fiber content of textiles using intelligent microscopy identification.
This document is applicable to various types of textiles made from cashmere, sheep's wool, and their blends, as well as to various types of textiles made from cotton, linen (such as flax and ramie), and their blends.
This document is not applicable to various types of textiles whose fibers are too damaged or adhered together to be identified.
For textiles made from fiber blends with significantly different longitudinal morphological characteristics, reference should be made to other relevant methods for identification.
