What are the specific effects of the water absorption of polyester fibers on the comfort of clothing
2025-03-18The poor water absorption of polyester fibers has both negative and positive effects on clothing comfort, as follows: 1. Negative impact Heat sensation: Due to the low water absorption of polyester fibers, sweat discharged from the skin surface cannot be absorbed in a timely manner. Sweat will accumulate between the skin and clothing, causing the skin to feel damp and stuffy, especially i
