摘要

PROBLEM TO BE SOLVED: To precisely and nondestructively evaluate deformation conditions of polyurethane elastic thread in textile. SOLUTION: A CPU 12 receives inputs of production conditions and a composition of polyurethane elastic thread to be measured (step S11), receives inputs of Raman spectrum data of the polyurethane elastic thread in textile to be measured (step S12), and then calculates a plurality of scatter peak intensity data (step S13). The CPU 12 calculates a scatter peak intensity ratio using the scatter peak intensity data of Raman spectrum (step S14), compares with the reference data recorded in a RAM 13 or the like (step S15), and then calculates a stretch ratio of the polyurethane elastic thread to be measured (step S16).
