The invention provides a method for manufacturing a piece of thermal inductance non-woven cloth for a sanitary napkin. The method comprises the steps of preparing a thermal inductance finishing liquid, roller-coating for sizing and performing drying treatment, wherein the thermal inductance finishing liquid is a composite thermal inductance effective substance consisting of a thermal inductance agent, a preservative, angelica sinensis essential oil, ethanol, an emulsifier, propylene glycol, polyethylene glycol 400, a filming agent and water; the components are reasonably matched; the thermal inductance is gentle and long-lasting and does not stimulate the skin. Besides, the method adopts a filming technique to perform after treatment on the non-woven cloth by the thermal inductance finishing liquid in a sizing mode, so that the infiltration of the thermal inductance effective components is effectively avoided, the utilization rate of the effective components is improved, the adhesion amount and the adhesion area of the effective components are easily controlled, and further, the quality stability of the non-woven cloth is effectively ensured. Meanwhile, the method is easy to achieve and low in cost and has good scale application prospect.
