Embodiment 1

[0020] A sanitary napkin for preventing side leakage, comprising: a water-permeable layer 3, a water-absorbing body 2 and a waterproof layer 1 stacked in sequence; As for the air-permeable membrane 4, water-permeable holes are distributed on the use surface of the first air-permeable membrane 4; the first air-permeable membrane is used to prevent the liquid entering the water-absorbing body 2 from overflowing. The waterproof layer 1 and the first breathable membrane 4 are PE breathable membranes.

[0021] The first air-permeable membrane 4 covers the use surface of the water-permeable layer 3, while the periphery of the first air-permeable membrane 4 extends to the back of the water-absorbing body 2 away from the use surface, but does not completely wrap the Absorbent 2 for improved breathability. Water-permeable holes are distributed only on the use surface of the first air-permeable membrane.

[0022] The sanitary napkin is elongated, and side non-woven fabrics 5 are provi...

Embodiment 2

[0029] On the basis of Embodiment 1, this embodiment has the following modifications

[0030] The water-absorbing body 2 is wrapped by a second air-permeable membrane (PE air-permeable membrane), wherein the part of the second air-permeable membrane on the use surface of the water-absorbing body 2 is distributed with water-permeable holes to prevent the liquid from entering the water-absorbing body 2 Spill.

[0031] Optionally, the use surface of the first air-permeable membrane 4 is covered with a surface layer of non-woven fabric 6, and the surface layer of non-woven fabric plays the role of evenly distributing water, which facilitates uniform and rapid infiltration of liquid from the outside into the water-absorbing body.

Abstract

The invention relates to a sanitary napkin capable of preventing side leakage. The sanitary napkin comprises a permeable layer, a water absorption body and a waterproof layer which are sequentially arranged in a laminated mode. A breathable film (namely, the breathable film wraps the water absorption body in a U shape) covering the water absorption body is arranged on the use surface of the permeable layer, and permeable holes are distributed in the use surface of the breathable film; the periphery of the breathable film extends to the back face, far away from the using face, of the water absorbing body, but the water absorbing body is not completely wrapped, so that the breathability is improved. The middle part of the sanitary towel extends towards two outer sides to form protective wings; the sanitary towel is rectangular, and the protective wings are also rectangular, so that leftover materials are reduced, materials are fully utilized, and the influence of redundant leftover materials on the environment is avoided. The wing is formed by independently cutting a layer of independent material and then compounding or adhering to the back of the product, and 1 to N layers of waterproof materials may be adhered to the back of the wing layer. The non-woven fabric covers the use surface of the water absorption body, the non-woven fabric plays a role in uniformly distributing water, and liquid uniformly and quickly permeates into the water absorption body.

Description

technical field [0001] The invention relates to a sanitary napkin for preventing side leakage. Background technique [0002] Sanitary napkins are a must for women during menstruation, and the pads often leak sideways during use, which affects the use effect of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sanitary napkin with simple structure and suitable for preventing side leakage. [0004] In order to solve the above problems, the present invention provides a sanitary napkin, comprising: a water-permeable layer, a water-absorbing body, and a waterproof layer stacked in sequence; the use surface of the water-permeable layer is provided with a first The air-permeable membrane (that is, the first air-permeable membrane is U-shaped wrapped on the water-absorbing body), only has water-permeable holes distributed on the use surface of the first air-permeable membrane; the first air-permeable membra...
