Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

An ultra-thin pant-type sanitary napkin, as shown in fig. 1, comprises an absorption body 1 and an elastic waist 2, wherein the elastic waist 2 is positioned at two ends of the absorption body 1, and the absorption body 1 is bent to form a ring shape with the elastic waist 2 to form a pant shape. The elastic waistline 2 is an annular structure consisting of soft non-woven fabrics and a plurality of rubber bands, wherein the non-woven fabrics wrap the rubber bands so that the pants-type sanitary towel can be stably fixed on a human body; the absorption body 1 both sides can be equipped with three-dimensional enclosure portion, three-dimensional enclosure portion comprises water-repellent cloth and rubber band, and wherein the rubber band is wrapped up in the water-repellent cloth completely, sets up three-dimensional enclosure portion and tightly laminates on the human body in the effect of rubber band, avoids producing the side leakage, and water-repellent cloth is comparatively soft, can not cause the sense of oppression for the user.

With reference to fig. 1 and 2, the absorption body 1 includes a non-woven fabric surface layer 11, a flow guide layer 12, an absorption layer 13, a fluff pulp layer 14, a breathable basement membrane 15 and a basement membrane non-woven fabric 16, the fluff pulp layer 14 is inserted into the absorption layer 13, the flow guide layer 12 is pressed on the absorption layer 13, and the non-woven fabric surface layer 11 is in an inverted C shape to cover the flow guide layer 12 and the absorption layer 13; the breathable basement membrane 15 is a PE breathable basement membrane with the gram weight of 12-60 g/m²The air-permeable basement membrane 15 is pressed at the bottom of the outer side of the non-woven fabric surface layer 11, and the basement membrane non-woven fabric 16 is spun-bonded non-woven fabricThe membrane non-woven fabric 16 is adhered to the bottom of the breathable basement membrane 15; the breathable bottom film 15 is breathable and impermeable, and the gap between the absorbing layer 13 and the breathable bottom film 14 is matched, so that the pant-type sanitary napkin has better breathability and cannot influence the fixation of the non-woven fabric surface layer 11 on the diversion layer 12 and the absorbing layer 13.

With reference to fig. 1 and 2, the nonwoven fabric surface layer 11 is soft hot air nonwoven fabric with a gram weight of 10-40 g/m²The denier is between 0.3 and 3.5, so that the surface layer 11 of the non-woven fabric has good softness and high infiltration speed; the flow guide layer 12 is made of hot air non-woven fabric with the gram weight of 10-40 g/m²The denier is also between 0.3 and 3.5 denier to avoid increasing the extra thickness of the absorption body 1, so that the thickness of the absorption body 1 is reduced.

Referring to fig. 2 and fig. 3, the absorption layer 13 includes base paper 131 and polymeric water-absorbent resin particles 132, wherein the polymeric water-absorbent resin particles 132 are pressed in the middle of the two layers of base paper 131, and the 3 gram weight of the polymeric water-absorbent resin is 10-300 g/m²The particle size is 30-100 meshes, the water retention capacity is not lower than 25g/g, and the liquid passing capacity is not lower than 0.5 mL/min; all be equipped with fold and gap on the body paper 131 on absorbed layer 13 surface, it can make liquid can follow the outward diffusion of fold channel to set up the fold, avoid liquid too concentrate and make this regional polymer water-absorbent resin granule 132 imbibition saturation and lead to the problem of dry and comfortable nature, and after the liquid diffusion, the cooperation gap makes liquid infiltration volume increase in unit interval, the high liquid absorption volume of cooperation polymer water-absorbent resin granule 132, directly improve imbibition efficiency, make non-woven fabrics top layer 11 can resume dry and comfortable in extremely fast time.

With reference to fig. 2 and 3, the absorbent layer 13 is folded into an inverted G shape and is wrapped with a fluff pulp layer 14 in 360 degrees, the fluff pulp layer 14 is a thin fluff film made of wood pulp fibers and having a thickness of less than 0.5mm, and the size width of the folded absorbent layer 13 is not more than half of the length of the pants-type sanitary napkin, so that a space area 17 is formed between two sides of the absorbent layer 13 and the nonwoven fabric surface layer 11, and the space area 17 is a cavity; the absorbent layer 13 adopts the folding shape to arrange, can improve the imbibition ability of this part, avoids liquid diffusion not smooth time liquid to lead to the problem of unable infiltration because of the saturation of polymer water-absorbent resin granule 132, guarantees that liquid homoenergetic is absorbed by absorbent layer 13, avoids the extrusion to reverse ooze. Meanwhile, the space area 16 is arranged, so that the air permeability can be improved, the two sides of the sanitary towel can be more easily bent, and the softness is improved. The extremely thin fluff pulp layer 14 is arranged, which can assist the liquid to diffuse all around, so that all the high polymer water-absorbent resin particles 132 in the absorption layer 13 can absorb the liquid, thereby improving the liquid absorption efficiency and effectively avoiding reverse osmosis.

In order to verify the utility model discloses good hydroscopicity and dry and comfortable nature effect, carried out following experiment:

choose the pants-type sanitary towel of the utility model to be example 1, choose among the prior art absorbent layer 13 and adopt the pants-type sanitary towel of fluff pulp and polymer water absorbent resin granule to carry out the experiment for comparative example 1, wherein, example 1 absorbs main part 1 thickness and is about 4mm, and comparative example 1 absorbs main part 1 thickness and is about 9 mm.

Pouring animal blood on two experimental samples for 2 times, 5mL each time, and 10 minutes at 2 intervals, and recording the time for completing absorption as the absorption speed in unit of s; after each 5mL of animal blood was absorbed, 10g of filter paper was placed on the pants-type sanitary napkin under a 1.2kg weight for 1min, and the increase in the grammage of the filter paper in g was measured to measure the reverse osmosis amount.

The results of the measurement are shown in the following table; by comparing the data in the statistical table, it is clear that the pant-type sanitary napkin of example 1 absorbs blood for 5 or 6 seconds, and has a particularly high absorption rate, a very small reverse osmosis amount, and a particularly good dryness, whereas the pant-type sanitary napkin of comparative example 1 has not only a low absorption rate but also a very large reverse osmosis amount, and has a larger thickness than that of example 1.

To sum up, the utility model discloses a compound paper that absorbs water of polymer and a small amount of fluff pulp fully combine, make whole piece of cloth body very fine and thin, the compliance increases, and liquid infiltration speed can be quickened again simultaneously, reduces liquid and remains on the surface, improves dry and comfortable nature greatly, has improved the gas permeability.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
