Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

The utility model provides a from breathing antibacterial sanitary towel with air pivot, as shown in fig. 1-4, including sanitary towel body 1, sanitary towel body 1 comprises ventilative layer 11, antibacterial layer 12, layer 13 that absorbs water, lock water layer 14 and bottom 15, and the inner wall of sanitary towel body 1 is provided with side leakage layer 2, and the both sides of sanitary towel body 1 all bond there is flank 3, and sanitary towel body 1 and the bottom of flank 3 all bond there is bond line 4, and the bottom of bond line 4 bonds there is protective film 5.

In this embodiment, the breathable layer 11 includes a comfortable layer 111, a breathable film 112 is bonded to the bottom of the comfortable layer 111, a breathable film 113 is bonded to the bottom of the breathable film 112, and the bottom of the breathable film 113 is bonded and fixed to the top of the bacteriostatic layer 12.

The ventilation property of the sanitary towel can be greatly improved through the ventilation film 112 in the ventilation layer 11, so that the stuffy and uncomfortable feeling of a user can be reduced to a great extent, the breeding of bacteria can be reduced, and the sanitary and comfortable sanitary towel is more sanitary and comfortable.

The bottom of the water absorption layer 13 and the top of the bottom layer 15 are respectively bonded and fixed with the top and the bottom wall of the water locking layer 14, and the top of the water absorption layer 13 is bonded and fixed with the bottom of the bacteriostatic layer 12.

The bacteria can be well prevented from breeding through the bacteria inhibiting layer 12 on the water absorbing layer 13, so that the sanitary towel is more sanitary and comfortable to use, and the risk of diseases is greatly reduced.

The comfort layer 111 is composed of pure cotton and polyacrylonitrile fiber, and the proportion of the pure cotton to the polypropylene fiber is 6: 4, the structure of the comfort layer 111 is a dry mesh funnel type.

In addition, the material of the breathable film 112 is low density polyethylene, the material of the breathable film 113 is polypropylene fiber, the low density polyethylene has good air permeability and water permeability, so that the air permeability and the liquid flowing speed into the water absorbing layer 13 can be increased, the movement and side leakage of the liquid when the liquid is not absorbed can be reduced, the polypropylene fiber does not absorb moisture, the weight of the whole sanitary towel can be reduced, and the usability is improved.

In addition, the material of antibacterial layer 12 is bamboo fiber, and antibacterial agent is added to the inside of antibacterial layer 12, and the antibacterial agent comprises 1.5% citric acid aqueous solution and 0.5% sodium citrate aqueous solution, and the organic acid bacteriostatic agent that adds can change antibacterial layer 12 and be weak acid environment to it is more difficult for breeding under weak acid environment bacterium.

The water absorbing layer 13 is made of a high molecular water absorbing resin, the high molecular water absorbing resin is prepared by using starch as a raw material, ammonium ceric nitrate as a chemical initiator and acrylonitrile as a monomer, the high molecular water absorbing resin can absorb liquid with the size being about 1000 times of the volume of the high molecular water absorbing resin, and can absorb a large amount of liquid, so the high molecular water absorbing resin is selected as the water absorbing layer 13.

The water locking layer 14 and the side leakage prevention layer 2 are both composed of high-molecular water-absorbent resin and polypropylene, and the ratio of the high-molecular water-absorbent resin to the polypropylene is 7: 3, the material of bottom 15 is the polyethylene, and lock water layer 14 can prevent that the flow is too big time, and the polymer water-absorbing resin wherein can carry out the secondary absorption to liquid, prevents to spill, and prevents that the side leakage layer 2 can be when the sanitary towel takes place the side deviation, and the liquid of side leakage can be blocked and absorb by the side leakage layer 2 of preventing of round in the sanitary towel to can prevent that the sanitary towel from taking place the side leakage, practicality greatly increased.

The adhesive layer 4 is an adhesive made of self-crosslinking acrylic resin as a main material, the protective film 5 is made of release paper, the release paper can not be stuck by the adhesive layer 4, the sanitary towel is convenient to fold and package, the sanitary towel is prevented from being adhered to each other between the surface and the face after being folded, and the sanitary towel cannot be unfolded in use and cannot be used.

In this embodiment, the upper surface of flap 3 is provided with four strengthening ribs, and four strengthening ribs all use the central line of sanitary towel body 1 as symmetry axis nature array respectively, and the strengthening rib can help folding flap 3 after reseing, prevents that it from folding the packing after, can't expand when opening, and then the effect of pasting is influenced, can probably take place to drop when the user uses, practicality greatly reduced.

When the self-breathing bacteriostatic sanitary towel with the air hinge is used, liquid is firstly sucked into the pure cotton in the comfort layer 111, but flows downwards to penetrate through the breathable film 112, the breathable film 113 and the bacteriostatic layer 12 under the action of osmotic pressure to enter the water absorbing layer 13, the high molecular water-absorbing resin in the water absorbing layer 13 can absorb the liquid, the high molecular water-absorbing resin can absorb the liquid with the volume being nearly 1000 times of the volume of the high molecular water-absorbing resin, so that a large amount of liquid can be absorbed, the comfortable layer 111 can be dried and comfortable quickly under the ventilation action of the breathable film 112 after the liquid in the comfortable layer is lost, the stuffy feeling of a user can be reduced to a great extent, the breeding of bacteria in a humid environment can be reduced, the sanitary and comfortable effects are achieved, the bamboo fibers in the sanitary and bacteriostatic effects can be achieved after the liquid flows through the bacteriostatic layer 12, and the added organic acid bacteriostatic agent can change the bacteriostatic layer 12 into a weak acid environment, bacterium is more difficult to breed under weak acid environment, can effectually prevent to absorb water and carry out breeding of bacterium on the layer 13, promoted sanitary safety greatly, when the flow was too big, the liquid of outflow can be absorbed by the polymer water-absorbing resin in the lock water layer 14 once more, when sanitary towel takes place the lateral deviation, the liquid of lateral leakage can be blocked and absorb by the lateral leakage layer 2 that prevents of round in the sanitary towel to can prevent that sanitary towel from taking place the lateral leakage, practicality greatly increased.
