With the development of the times and challenges such as resource scarcity, natural fibers like cotton, linen, silk, and wool are increasingly unable to fully meet the needs of modern production and daily life. As a result, the industry has intensified research and production efforts on new fibers in recent years. Polyamide ester fiber, as a novel fiber, exhibits excellent wearability and has been applied in the textile, apparel, and home furnishing sectors. However, routine testing has revealed that the current national standards lack detailed procedures for the qualitative analysis of polyamide ester fiber. Additionally, while chemical quantitative analysis methods for its blends with certain fibers, such as cotton, polyester, and nylon, have been established, there is no standardized method for quantifying its mixtures with other commonly used fibers, such as soybean protein fiber. Therefore, this study will further explore the qualitative analysis methods and specific operational procedures for polyamide ester fiber through visual observation, combustion testing, microscopy, polarized light analysis, melting point determination, and mid-infrared spectroscopy. Furthermore, it will investigate the use of the sodium hypochlorite/hydrochloric acid method for the quantitative chemical analysis of its blends with soybean protein fiber, aiming to provide a foundation for future testing and the development of relevant standards.
