Problems solved by technology

[0003] However, the above two methods have obvious disadvantages: the former usually has a higher cost, and will increase the weight of the product and even affect the moisture absorption effect; while the latter will lead to a short shelf life of the thermal sensitivity of the sanitary napkin or panty liner, and the thermal sensitive agent is easy to seep. The utilization rate is low, and the process is difficult to control

Abstract

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.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for preparing a heat-sensitive nonwoven fabric used for sanitary napkins. Background technique [0002] Women experience an uncomfortable cool sensation during menstruation, which is often relieved by hot compresses. In order to deal with this problem, sanitary napkins that can produce warming effects have been developed in the prior art. In order to realize the heating effect of sanitary napkins, the prior art mainly adopts the following two methods, one is to build a heating chip in the sanitary napkin; On the core layer, dry treatment is carried out, and the thermal agent plays a heating role during use. For example, the technical solution provided by the Chinese patent application "a sanitary napkin thermal agent" (application number CN201010271753.8) belongs to the latter type Condition. [0003] However, the above two methods have obvious disadvantages...
