Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

First, an embodiment

Example 1: a bacteriostatic and anti-reverse-osmosis sanitary towel is shown in figures 1 and 2 and comprises a sanitary towel body 1, wherein the sanitary towel body 1 sequentially comprises a bottom membrane 2, a first non-woven fabric layer 3 arranged on the bottom membrane 2, a water absorption paper layer 4, a second non-woven fabric layer 5, an anti-reverse-osmosis composite layer 6 and a face paper layer 7 from bottom to top. Wherein, the basement membrane 2 is a plastic waterproof film layer, a large number of micropores are arranged on the plastic waterproof film layer, and the diameters of the micropores are controlled between 0.1 and 0.3 nanometer. At this time, liquid cannot pass through the micro holes, and only gas can pass through the micro holes (not shown), thereby improving the air permeability of the anti-reflection sanitary napkin. And secondly, the absorbent paper layer 4 is formed by compounding a wood pulp layer and a high-molecular absorbent resin SAP particle layer, wherein the ratio of the wood pulp to the high-molecular absorbent resin SAP particles is 2: 1.

In order to improve the anti-reverse osmosis effect of the anti-reverse osmosis sanitary napkin, as shown in fig. 2 and 3, the anti-reverse osmosis composite layer 6 is composed of a lower anti-reverse osmosis layer 61 and an upper anti-reverse osmosis layer 62. Wherein the anti-reverse osmosis composite layer 6 is selected from an osmosis PE plastic film. The permeation PE plastic film is made of PE plastic, has certain thickness and hardness, and can stabilize the shape and the structure of the anti-reverse permeation layer 62. Secondly, a plurality of lower seepage holes 8 are arranged on the surface of the lower anti-seepage layer 61, the lower seepage holes 8 are in a funnel shape with a large upper part and a large lower part, namely the diameter of the lower seepage holes 8 is gradually reduced from one side close to the face paper layer 7 to the other side. At this time, the liquid on the upper anti-seepage layer can flow downwards to one side of the lower anti-seepage layer through the liquid level through the lower seepage holes 8; and the liquid on one side of the lower anti-seepage layer has a better anti-reverse seepage effect because the diameter of the lower seepage hole 8 close to the lower anti-reverse seepage layer 61 is smaller.

As shown in fig. 2 and 3, the upper anti-reverse osmosis layer 62 is located above the lower anti-reverse osmosis layer 61, the upper anti-reverse osmosis layer 62 is in a continuous wave shape, and a plurality of polyurethane glue dots one 9 are arranged at the connection part of the upper anti-reverse osmosis layer and the face paper layer 7, and the polyurethane glue dots one 9 can be used for connecting the upper anti-reverse osmosis layer and the face paper layer 7. Meanwhile, the polyurethane glue dots I9 and the lower seepage holes 8 are arranged up and down correspondingly, the upper anti-seepage layer 62 is provided with a plurality of flow guide holes 10 in the area close to the upper part of the lower anti-seepage layer 61, and the diameter of the flow guide is larger than or equal to the maximum diameter of the lower seepage holes 8. Therefore, the wavy upper reverse osmosis layer is covered on the lower osmosis hole 8 in a plurality of arc shapes, and the liquid above the upper reverse osmosis layer 62 is accelerated to be quickly drained to the lower part of the lower reverse osmosis layer 61 by utilizing the arc-shaped curved surface. On the other hand, in the process of movement of the human body, if the liquid which is not timely seeped between the upper anti-reverse osmosis layer 62 and the lower anti-reverse osmosis layer 61 is positioned, the probability that the reverse osmosis liquid is directly contacted with the skin again can be reduced under the shielding effect of the arc-shaped curved surface of the upper anti-reverse osmosis layer 62, so that the protective effect on the skin is further improved.

As shown in fig. 2, in order to further increase the infiltration speed, the lower anti-infiltration preventing layer 61 between two adjacent lower infiltration holes 8 is smoothly transited from one end close to the face paper layer 7 to the other end along an arc-shaped curved surface. Therefore, the horizontal position point of the upper anti-reverse osmosis layer 62 positioned between two adjacent lower osmosis holes 8 is higher than the horizontal position point close to the lower osmosis hole 8, at the moment, the liquid can quickly pass through the lower osmosis hole 8 along the arc-shaped curved surface, and the infiltration speed is improved. In order to further accelerate the liquid infiltration speed, the diversion holes 10 are positioned at the highest horizontal position of the arc-shaped curved surface of the lower anti-infiltration preventing layer 61. Therefore, when liquid is arranged between the upper anti-reverse-osmosis layer 62 and the lower anti-reverse-osmosis layer 61, the liquid can pass through any one of the lower osmosis holes 8 along the left and right arc-shaped curved surfaces, and the speed of liquid infiltration is greatly increased.

Meanwhile, as shown in fig. 2 and 3, in order to improve the stability of the existence of the cavity between the anti-reverse-osmosis layer and the lower anti-reverse-osmosis layer 61, a plurality of second polyurethane glue dots 11 arranged at intervals are also arranged at the junction between the upper anti-reverse-osmosis layer 62 and the lower anti-reverse-osmosis layer 61. The presence of the second polyurethane glue sites 11 at this time helps to maintain the wavy shape of the upper anti-reverse osmosis layer 62, while also helping to improve the stability of the presence of the cavity between the anti-reverse osmosis layer and the lower anti-reverse osmosis layer 61.

The processing method comprises the following operation steps:

crushing wood pulp, mixing the crushed wood pulp with high-molecular water-absorbent resin SAP particles, and pressurizing to obtain a water-absorbent paper layer 4; wherein the ratio of the wood pulp to the SAP particles is 2: 1.

Step two, conveying the non-woven fabric onto a conveyor belt, uniformly placing the water-absorbing paper layer 4 on one side of the non-woven fabric along one side of the extending direction of the non-woven fabric, folding and covering one side of the non-woven fabric, which is far away from the water-absorbing paper layer 4, above the water-absorbing paper layer 4, and obtaining a cotton core after coating;

and step four, cutting the space between the first nonwoven fabric layer 3 and the second nonwoven fabric layer 5 after the net pressing to remove redundant nonwoven fabrics, and gluing and fixing.

Step five, cutting off the cotton core obtained in the step four according to requirements, sequentially compounding the anti-reverse-osmosis composite layer 6 and the face paper layer 7 on the non-woven fabric layer two 5, and gluing and fixing;

simultaneously compounding the base film 2 on one side of the non-woven fabric layer I3, which is far away from the non-woven fabric layer II 5, and then gluing and compounding a layer of centrifugal paper on one side of the base film 2, which is far away from the non-woven fabric layer I3;

seventhly, cutting the finished product into sections, folding and fixing;

and step eight, packaging the finished product.

In the fifth step, the nano silver functional chip 12 and the anti-reverse osmosis composite layer 6 are compounded on the second non-woven fabric layer 5.
