Composite sanitary napkins with heating element and method for preparing and packing thereof

Abstract

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.

Description

technical field

[0001] The invention relates to a sanitary napkin and its preparation and packaging method in the feminine hygiene product manufacturing industry, in particular to a heating element composite sanitary napkin and its preparation and packaging method. Background technique

[0002] Sanitary napkins are known as one of the "Top Ten Inventions That Influenced Human Beings in the 20th Century" and have already become an indispensable "companion" in women's lives. Some women, especially young women, often experience dysmenorrhea during their periods. At this time, in addition to using medicine, a heating body (such as a hot water bottle) is often used to cover the navel below to warm the uterus and reduce pain. But this method is both inconvenient and affects life, and it is impossible to warm the uterus for a long time and uninterruptedly. With the mass use of sanitary napkins, there have been some patent reports on sanitary napkins for reducing dysmenorrhea in r...

Examples

Embodiment 1

[0028] Polypropylene fiber spunbonded non-woven fabrics with an average fiber diameter of 15 microns and an area density of 20 g / m2 are made by spunbond technology, and polypropylene fiber spunbond nonwovens with an average fiber diameter of 2 microns and an average pore diameter of 3 microns are made by meltblown technology. Polypropylene fiber melt-blown non-woven fabric, and then the above three sheets are superimposed and bonded according to the structure that the upper and lower layers are spun-bonded non-woven fabrics and the middle layer is melt-blown non-woven fabric to form a breathable layer of a sandwich composite structure. In the same way, make another breathable layer.

[0029] Mix the reduced iron powder with a particle diameter of 100 mesh, sodium chloride and activated carbon according to the weight ratio of 90:5:5 and press it into a sheet, then put it in the middle of the two air-permeable layers, and put the three It becomes a seven-layer heating element gr...

Embodiment 2

[0033] The viscose fiber spunlace non-woven fabric with an average fiber diameter of 20 microns and an area density of 20 g / m2 is made by spunlace technology, and the non-woven fabric with an average fiber diameter of 0.8 microns and an average pore diameter of 1 micron is made by meltblown technology. Polypropylene fiber melt-blown non-woven fabric, and then the above three sheets are superimposed and bonded according to the structure of the upper and lower layers of spunlace non-woven fabric and the middle layer of melt-blown non-woven fabric to form a breathable layer of sandwich composite structure. In the same way, make another breathable layer.

[0034] Mix the reduced iron powder with a particle diameter of 120 mesh, sodium chloride and activated carbon according to the weight ratio of 85:10:5 and press it into a sheet, then put it in the middle of the two air-permeable layers, and put the three It becomes a seven-layer heating element group layer by hot rolling.
