The investigation of qualitative and quantitative testing methodologies for elastic fibers
The article qualitatively analyzes spandex,polyolefin elastic fibers,and diene elastic fibers using conventional fiber iden-tification methods.It also explores advanced testing techniques like infrared spectroscopy,thermogravimetric analysis,differential scanning calorimetry,and laser Raman spectroscopy to enhance the qualitative analysis of elastic fibers and expand the range of identification methods for these three types of fibers.Additionally,it introduces commonly used quantitative methods for analyzing elastic fibers and investigates the application of near-infrared spectroscopy in quantitative analysis to explore novel approaches for quantifying elastic fibers.
