What is the water absorption principle of ultrafine fiber beach towels

Ultra fine fibers are generally polyester nylon composite fibers, which are formed into ultrafine single fibers with a diameter much smaller than ordinary cotton fibers through physical splitting technology. A large number of micro scale capillary micro pore structures are formed between fibers and inside single fibers, relying on the capillary effect to achieve water absorption: when the fabric comes into contact with water, under the capillary force, water can quickly penetrate into the fiber gaps and be continuously adsorbed and stored, without relying on the fiber itself to expand and lock water.

Compared to cotton fibers that rely on their own expansion to absorb water, ultrafine fibers have abundant capillary pore channels, faster water absorption rate, and larger water storage capacity; At the same time, the contact interface characteristics between fibers and water molecules make the adsorbed water more easily volatile, thus the fabric has excellent quick drying properties while possessing strong water absorption ability.
