Scope

This document describes the test method for the tensile properties of ultra-short fibers of chemical fibers.
This document is applicable to polyester, meta-aramid, para-aramid, high-strength and high-modulus polyvinyl alcohol, polylactic acid, viscose, and lyocell ultra-short fibers with a length of 5 mm to 20 mm. Other ultra-short fibers can be used as a reference for testing.
