Exploration of optimization of quantitative chemical analysis efficiency for spandex products
Quantitative chemical analysis of composition content in fabrics containing spandex is a common laboratory inspection and testing project.This article aims to optimize and improve the efficiency of the experiment,and explores and analyzes from four aspects:the best choice of standard in the two components of spandex,the best choice of scheme in the three components,the correction coefficient for the mass loss of the insoluble component polyester fiber in the corresponding reagent hydrochloric acid in the three components,and the influence of the drying time of spandex residue on the test results.This provides reference and assistance for the laboratory.
