ウールの新規防しわ性評価試験方法とその有効性 A New Method and Its Efficiency to Evaluate the Wrinkle-Resistance of Wool
A novel method to evaluate the wrinkle-resistance of woolen fabrics is proposed together with several experimental tests to check its efficiency, which enables us to follow the relaxation behavior of fabrics from wrinkled states, with higher reliability as well as by with greater ease than the conventional methods such as the Multiple-Pleats Test, IWS Method, JIS-L-1059's A to D, etc. Experiments proved the method is strong in two respects: Good reproducibility can be achieved because measurement is always performed in the state at which the regain of the cloth specimen is saturated in the sample-conditioning atmosphere; and high precision or resolvability is guaranteed since the bias caused by the difference in humidity can be removed if the common conditions be set in all tests. This technique was applied to the analysis of the relaxation in the wrinkles that are brought on woolen slacks by actual wearing conditions. The results obtained, being compared with the laboratory ones, proved the practical validity of the new method and gave useful information.
