DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] First embodiment

[0022] See also Figure 1-Figure 3 A silk sanitary napkin comprises wings 1 respectively arranged on the left and right sides of a silk surface layer 2, the bottom surface of the silk surface layer 2 is connected to the top surface of a guide layer 3, the bottom surface of the guide layer 3 is connected to the top surface of a SAPP layer 4, the bottom surface of the SAPP layer 4 is connected to a waterproof and breathable bottom membrane 5, one end of the wing 1 is arranged on the silk surface layer 2, the outer side of the guide layer 3 is connected to the wing 1, and the other end of the wing 1 is connected to the top surface of the waterproof and breathable bottom membrane 5.

[0023] In this embodiment, hot melt adhesive particles can be sprayed on the connecting parts, such as the area between the outer side of the guide layer 3 and the protective wing 1, and then the outer side of the guide layer 3 and the protective wing 1 are connected together by hot pressing.

[0024] The guide layer 3 covers the SAPP layer 4 .

[0025] The outer periphery of the guide layer 3 is in contact with the waterproof and breathable base membrane 5 .

[0026] The SAPP layer 4 is a single layer or a stacked layer, and the middle of the stacked layer is an overlapped portion.

[0027] The thickness of the SAPP layer 4 is 1.0-5 mm.

[0028] In this embodiment, the guide layer 3 is made of a water-permeable and air-permeable material.

[0029] The SAPP layer 4 is provided with needle-punched flow guide holes 4.1, which are arranged in an array, with a lateral spacing d between adjacent flow guide holes 4.1 of 1.0 to 10 mm, and a vertical spacing b between adjacent flow guide holes 4.1 of 1.0 to 10 mm.

[0030] By providing the guide holes 4.1, the liquid can be quickly guided into the SAPP layer 4, so as to quickly absorb water and prevent leakage. In addition, the guide holes 4.1 can be formed by the needle plate moving up and down to quickly puncture the SAPP layer 4 during processing.

[0031] One end of the wing 1 is folded inwards and crimped together with itself.

[0032] In this embodiment, the edge thickness of the wing 1 can be enhanced by the folded and crimped parts, thereby forming a water retaining wall at the edge of the guide layer 3 to prevent liquid from leaking out.

[0033] The silk surface layer 2 is provided with embossing for guiding flow.

[0034] The bottom surface of the waterproof and breathable bottom film 5 is connected to the release paper 8 through the adhesive layer 6 .

[0035] The adhesive layer 6 is composed of three or more adhesive strips arranged at intervals.

[0036] In this embodiment, the SAPP layer 4 is made of pure wood pulp paper or wet-strength paper, to which components such as high molecular water-absorbing resin, rubber powder and fluff pulp are added, and finally processed by heat-sealing and gluing processes.

[0037] The wet strength paper is absorbent paper added with a wet strength agent.

[0038] In this embodiment, the SAPP layer 4 is a single layer.

[0039] Second embodiment

[0040] See also Figure 4 In this embodiment, the SAPP layer 4 is a stacked layer, and the middle of the stacked layer is an overlapping portion.

[0041] In this embodiment, the local thickness of the SAPP layer 4 can be increased by arranging the overlap, and the water absorption capacity can be further improved at the overlapped part to meet the different needs of female users.
