The invention relates to the technical field of high-performance
polyester fibers, and discloses a
dry skin-friendly
fiber fabric, a preparation method thereof and application of the
dry skin-friendly
fiber fabric in underwear. The preparation method of the dry and comfortable
skin-friendly
fiber fabric comprises the following steps: carrying out reaction on
terephthalic acid,
ethylene glycol and an antibacterial modified diamide
diol monomer to obtain modified
polyester; the modified
polyester and the polyester master batch are mixed and spun, and the modified profiled polyester fiber is obtained; dipping the modified profiled polyester fiber in a finishing liquid containing a
biopolymer finishing agent to obtain the high-performance polyester fiber, blending and knitting high-performance polyester fibers, cotton fibers and mulberry silk fibers to obtain a
dry skin-friendly fiber fabric; the dry and comfortable
skin-friendly fiber fabric has excellent antibacterial performance,
moisture absorption performance and
skin-friendly performance, the skin can be kept dry and comfortable, safe and comfortable wearing experience is provided for a wearer, and the dry and comfortable skin-friendly fiber fabric can be used for underwear and other underwear materials.
