The cotton has the characteristics of short planting period, long fiber, good water absorption effect and the like, the water absorption of the cotton with the same volume is more than that of wood pulp, and the cotton serving as an absorption core body is applied to hygienic products and can fully exert the characteristics of softness, naturalness, water absorption, high strength and the like.
The proportion of the cotton and the water-absorbent resin is matched, and the cotton and the water-absorbent resin can play roles of high absorption, quick water locking and the like. The cotton fiber interweaving process is utilized, cotton serves as a main body structure for bearing the water-absorbent resin, and the occurrence of faults in the using process of the sanitary product is reduced. The application of the cotton needling process and the use of a large amount of lower adhesive glue reduce the skin irritation and the release of toxic and harmful substances possibly brought in the use process of the sanitary product. Meanwhile, the process has the advantages that the high water absorption effect of cotton is utilized, the use proportion of the water-absorbent resin is reduced, the natural decomposition period of the waste sanitary products is greatly reduced, and the ecological environment protection and the development of the green sanitary product industry are facilitated.
