NOVELTY - Preparation of multifunctional underwear fabric comprises: adding 7-10 pts. wt. pure cotton knitted fabric into 35-50 pts. wt. composite finishing liquid, heating and dipping treatment, two dipping-two rolling, where rolling liquid rate is 60-70%, water washing, drying at room temperature, drying, baking to obtain the multifunctional underwear fabric. The preparation method of the composite finishing liquid is as follows: providing 15 -20 pts. wt. wormwood essential oil microcapsule dispersion liquid, 5-10 pts. wt. graphene dispersion, 1-3 pts. wt. polyurethane, and 1-3 pts. wt. softening agent, mixing, stirring to obtain the composite finishing liquid. USE - Preparation of multifunctional underwear fabric. ADVANTAGE - The multifunctional underwear fabric has good antibacterial performance and far infrared performance, The multifunctional underwear fabric after 20 times, 50 times washing and testing, fabric has good washing durability. The multifunctional underwear fabric has fabric thickness, ventilation, moisture permeability and bursting strength, finding the change rate of each performance of the fabric after finishing the function is small, substantially not affecting the service performance.
