Abstract

The invention provides a method for manufacturing constant-temperature non-woven cloth for a sanitary product. According to the method, a constant-temperature phase-change micro-capsule finishing liquid, which takes paraffin as a core material and chitosan and sodium alginate as wall materials, is prepared by a phase-change micro-capsule technique and then is utilized to perform sizing treatment on a hot-air non-woven cloth base material, and furthermore, the base material is dried so as to obtain the constant-temperature non-woven cloth for the sanitary product. According to the method, the constant-temperature function of the non-woven cloth is achieved by the phase-change micro-capsule technique, and as the used phase-change material and a filming agent are free of toxicity or irradiation on skin, the non-woven cloth is safe to use. The constant-temperature non-woven cloth prepared by the method can be widely applied to the field of sanitary products, is particularly applied to sanitary products such as sanitary napkins and paper diapers which contact skin for a long time, can effectively maintain an appropriate environment temperature, and brings conformable sense experience for users.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a method for preparing a constant temperature non-woven fabric used in sanitary products. Background technique [0002] Since sanitary products such as sanitary napkins and paper diapers will be wrapped and in contact with the skin for a long time during use, it is easy to cause the temperature of the contact position on the body surface to rise and cause stuffiness and discomfort when it is in hot summer or after a certain exercise. lead to the growth of microorganisms; in addition, since women's private parts may feel cold during menstruation, if sanitary napkin products can maintain a relatively constant temperature to avoid local overcooling, it can make users more comfortable. Therefore, it is necessary to maintain such hygienic products within a relatively constant temperature range to avoid overheating or overcooling, thereby bringing more comfortable sensory ex...
