In the state of exercise, the human body is prone to sweating. When the sweat on the skin contacts the clothing, the sweat will be absorbed by the fabric. If the fabric cannot quickly discharge the sweat or evaporate it into the air, the fabric will be in a wet state, and when it contacts the skin, it will make the human body feel sticky or stuffy, and it is easy to breed bacteria. Therefore, the research and development of fabrics with moisture-absorbing and quick-drying properties has a broad market and is also a major research hotspot in the current scientific research field. For example, Chinese patent CN118048708B provides a moisture-absorbing and quick-drying polyester fiber and fabric, which is made by polycondensation and spinning of dibasic acid and modified diol monomers, but the antibacterial property of the moisture-absorbing and quick-drying polyester fiber needs to be improved.
