Five types of fabrics were prepared with nano fibers and pure cotton fibers,whose core absorption performance,moisture conductivity,breathability,and drying performance were tested.The results show that the moisture conductivity,permeability,and drying performance of nanofiber fabrics are better than those of pure cotton fabrics.The fabric prepared with nano fibers and pure cotton fibers in a mass ratio of 80∶20 performs better in thermal and wet comfort.
