Scope
Scope: This document is applicable to various textiles made from a blend of polyester fibers and ethylene or propylene fibers; Main technical content: This document describes a method for determining the content of polyester fibers in a mixture of two components of polyester fibers and certain other fibers after removing non-fiber substances by using a concentrated sulfuric acid method. The polyester fibers are dissolved and removed from a mixture of known dry mass by concentrated sulfuric acid, and the residue is collected, washed, dried, and weighed. The percentage of the polyester fibers in the dry mass of the mixture is calculated using the corrected mass. The mass percentage of the polyester fibers is obtained from the difference between the two values.
