Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to a carbon fiber super-absorbent sanitary product. Background Art

[0002] Carbon fiber is widely used in various industries due to its unique physical and chemical properties. Carbon fiber has good physical antibacterial and deodorizing effects, but due to its high price, high gram weight (generally more than 100gsm on the market), black residue pollution of the machine, etc., it is difficult to apply carbon fiber in the field of sanitary products.

[0003] Incontinence products account for a large market share in sanitary products. As the name implies, incontinence products are used to absorb human urine, feces, etc. In addition to being able to absorb and dry instantly, these products also hope to be able to remove odors and inhibit bacteria, thereby protecting the skin contaminated by incontinence. Existing designs usually add some odor-absorbing SAPs, but this can only absorb some of the odor components in urine, such as NH3. In fact, after urine is decomposed and fermented by bacteria, it will also produce acetic acid, methyl mercaptan, indole, hydrogen sulfide and other odors. SAP cannot absorb all odors well. There are also some designs that add fragrances to cover up the odor, but not everyone can accept the mixed smell.

[0004] Of course, the main performance pursued by incontinence sanitary products is instantaneous absorption and dryness. Because incontinence products are mostly used for a long time, it is more important to keep the skin dry. The product structure of sanitary products is limited by the production capacity of the machine and basically cannot change much. Most of them still provide comfort through the surface material and diffuse the liquid through the diversion layer. Therefore, the characteristics of the material and the structural design have a very important impact on the overall performance of the product. Summary of the invention

[0015] The overall structure is glued to the base film layer and the release paper layer in sequence, and then the hygienic product is formed by circumferential sealing, compaction, secondary compaction and cutting.

[0016] As an improvement of the above technical solution, the concave point is an inverted trapezoidal concave point;

[0017] The concave points are distributed at the front end and the rear end of the structure surface layer, respectively forming elliptical concave point distribution areas.

[0018] As an improvement of the above technical solution, the three-dimensional guard is made of SMS non-woven fabric wrapped with elastic band, wherein the basis weight of the SMS non-woven fabric is 13-25gsm.
