Description

Technical Field

[0001] The utility model relates to a female product, in particular to a sanitary napkin with an ice silk feeling surface layer. Background Art

[0002] Non-woven fabric, also known as nonwoven fabric, is a fabric that does not require spinning and weaving. Due to its advantages such as light weight, softness, breathability, environmental protection and low cost, it is widely used in medical and health care, household goods, clothing industry, industry, packaging materials and other fields.

[0003] The structure of conventional sanitary napkins on the market is generally divided into three layers: "skin-friendly upper layer", "absorbent middle layer" and "leakage-proof lower layer"; they meet the physiological needs of women during menstruation, but often women's comfort during exercise is affected. The skin-friendly layer of existing sanitary napkins still has room for improvement. Summary of the invention

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0019] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0020] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0021] Reference Figure 1 , 2 A sanitary napkin with an ice silk feeling surface layer comprises a surface layer 1 located on the upper layer, an absorbent layer 2 located in the middle layer and a leak-proof layer 3 located in the lower layer, wherein the surface layer 1 is made of hot air non-woven fabric, and the hot air non-woven fabric is formed by a thermal process from spiral short fibers, and 3D embossing is provided on the surface layer 1. The hot air non-woven fabric made of spiral short fibers is densely covered with a large number of gaps, which can effectively improve the fluffiness of the surface layer, increase the three-dimensional sense of the surface layer through 3D embossing, and further improve its resilience, which can bring great comfort to users.

[0022] The contact points between the spiral short fibers are the melting points of the hot air nonwoven fabric.

[0023] The area of ​​the 3D embossing is larger than the area of ​​the absorption layer 2 .

[0024] The 3D embossing is evenly distributed on the surface layer 1 .

[0025] The height of the 3D embossing is 0.1-2 mm.

[0026] The absorption layer 2 is provided with a plurality of arranged flow guiding channels, and the surface layer 1 is provided with flow guiding holes corresponding to the flow guiding channels.

[0027] The absorption layer 2 includes a guide layer and a water absorption layer, and the guide layer is located above the water absorption layer.

[0028] The surface layer 1 is provided with an anti-side flow guide groove at the edge of the absorption layer 2 .

[0029] The anti-leakage layer 3 is made of a waterproof and breathable film, and wing pieces are provided on both sides.

[0030] The method for making the surface layer comprises the following steps:

[0031] S1: Opening, preliminarily loosening the spiral short fiber raw materials and removing fiber clumps;

[0032] S2: Combing to separate the fibers into individual strands;

[0033] S3: Laying the web, evenly laying the single spiral short fibers to form a fiber web;

[0034] S4: hot air, which consolidates the fiber web through heated air to form it;

[0035] S5: Ironing: heating and ironing the non-woven fabric;

[0036] S6: winding, winding the prepared non-woven fabric into a roll;

[0037] S7: Slitting, cutting the non-woven fabric roll into a surface layer according to the size of the sanitary product;

[0038] S8: 3D embossing, embossing the non-woven surface layer;

[0039] S9: Punching, punching small holes evenly or in a specific arrangement on the surface layer of the non-woven fabric.

[0040] The present invention adopts spiral short fibers as production raw materials, which have relatively more gaps. The contact points between the fibers are melted and fixed through a hot air process to form a non-woven fabric with dense gaps. 3D embossing and punching are performed on the non-woven fabric to reduce the skin contact surface layer and form more channels. The temperature of the private parts of the human body is discharged from the body through the fiber gaps and channels, so that the airflow at the skin contact part flows with the outside, resulting in a temperature difference and forming an ice silk feeling.

[0041] In the step S1, a loosening machine is used to break up and loosen the bulk or bundled fiber raw materials through mechanical action, so that the fibers become more fluffy and discrete.

[0042] In step S2, the fiber raw material is fully opened and combed by a carding machine to separate the fibers into single strands and to make the fibers straight and parallel as much as possible.

[0043] In step S4, the temperature of the hot air is 150°C-170°C, the heating time is 15 seconds, and a hot air box device is used to heat and consolidate the fiber web. Due to the size of the equipment, multiple hot air boxes are generally connected in parallel, with a number of 8-10. The time it takes for the fiber web to pass through all the hot air boxes is 15 seconds.

[0044] In step S5, a hot roll is used to drive the nonwoven fabric to iron the ends of the spiral short fibers. In the web laying process, it cannot be guaranteed that all the short fibers have their ends as consolidation points. Therefore, after the hot air process, the surface of the nonwoven fabric has a large number of short fiber ends, and the ends extend outward irregularly. If used directly, there will be a burr feeling. Therefore, a hot roll is used to drive the nonwoven fabric. The hot roll squeezes and heats the short fiber ends on the nonwoven fabric at the same time, so that the short fiber ends form new consolidation points with other fibers, or the direction of the short fiber ends is changed to ensure that the short fiber ends do not extend outward.

[0045] The side of the nonwoven fabric in contact with the heat roller is a smooth side, which is the side in contact with the skin when making sanitary products, and the other side is a fleece side.
