Abstract: With the increasing popularity of wool fabrics, the problem of their complicated washing and care has gradually emerged. The wide application of household tumble dryers has provided a convenient solution for drying wool fabrics. However, consumers often find it difficult to accurately distinguish which dryers are truly suitable for wool fabrics and which ones may pose a risk of damaging the clothes. At present, the domestic standard system for the drying performance of wool fabrics is still not perfect. Only a few group standards are available for reference, and their testing methods mostly draw on the norms of the International Wool Secretariat (IWS). Therefore, select the testing method of the IWS for interpretation, aiming to provide clear R&D guidance for relevant manufacturing enterprises through in-depth analysis of this standard test method, assist in the development of wool-friendly dryers that better meet market demands, thereby enhancing user experience and promoting the overall development of the industry.
