A. First we can burn and extinguish it to identify the natural and chemical fibers.
B. If it is a natural fiber, use a microscope to identify various types of plant fibers and
animal fibers. If it is a chemical fiber, the difference in melting point, specific gravity,
refractive index, and solubility of the separated fiber is distinguished one by one.
C. When identifying mixed fibers and blended yarns, it can use a microscope to confirm that
it contains several fibers, and then identify them one by one in an appropriate manner.
D. Regarding dyed or finished fibers, it is usually necessary to stop dyeing and peeling or
other appropriate pre-treatment to ensure that the identification results are reliable.
