The invention relates to a heater composite
sanitary napkin and a preparation and packaging method thereof. The heater composite
sanitary napkin is composed of a conventional
sanitary napkin and a heater combined layer, the heater combined layer is composed of upper and lower surface
layers of air-permeable
layers with the same structures and materials and a middle heating substance sheet layer, the middle sheet of the air-permeable
layers is
melt blowing nonwoven fabric, the upper and lower layers are
nonwoven fabric which is made by the composite technology; and the heating substance sheet layer is formed by mixing and pressing
metal signal substance,
sodium chloride and
activated carbon according to the proportion. The heating sheet layer is firstly arranged in the heater combined layer which is provided with seven layers and is formed between the two pre-made air-permeable layers by hot rolling and then is fixed between an
absorption layer and a mesh
surface layer of the sanitary napkin by binding or hot rolling, the
vacuum pumping is carried out or protective gas is introduced, the exterior thereof is packaged by an
oxygen isolating thin film, and the formed
package body can be stored for a long time. The reaction is activated by tearing the thin film. The product has the effects of waterproof, anti-leakage, convenient and long-term stable heating, warming
uterus and reducing dysmenorrheal. The preparation method is simple and the packaging effect is good.
