Paper diaper and preparation method thereof

Abstract

The invention relates to a paper diaper and a preparation method thereof. The paper diaper comprises a surface layer, three-dimensional protective enclosures, an absorption core body and a bottom layer, wherein the absorption core body comprises two core body parts which are parallel to each other in the length direction of the paper diaper and are arranged at an interval. The invention also relates to a preparation method of the paper diaper. The preparation method comprises the following steps: a body is formed by using a non-woven fabric; a PE film is adhered to the center of the body; thetwo three-dimensional enclosures are formed on the body; two core body parts are arranged in parallel in the length direction of the paper diaper, and an isolation space is formed between the two corebody parts; the two core body parts are simultaneously coated with the surface layer from the top, and the surface layer is folded at the edges of the core body parts, so that the edges of the surface layer are adhered to the bottom surfaces of the end parts of the core body parts; and the bottom surfaces of the two core body parts coated by the surface layer formed in the previous step are adhered to the PE film between the two three-dimensional enclosures through a hot melt adhesive, and the end parts, close to the three-dimensional enclosures, of the core body parts and the three-dimensional enclosures are arranged at intervals.

Description

technical field [0001] The invention relates to a paper diaper and a preparation method thereof. The invention relates to the field of sanitary care products, in particular to a paper diaper with a three-dimensional absorbent core and an industrial preparation method thereof. Background technique [0002] As a disposable sanitary product, diapers are mainly used to absorb urine and can be discarded after use. They are suitable for children, the elderly or people with disabilities. [0003] Common diapers currently on the market are usually composed of: surface layer, core, elastic band, three-dimensional guard, PE film and water-repellent bottom layer, among which the core is the main component used to absorb urine in diapers. Due to the different needs of different groups of people, the design of the diaper core is also different, usually including: fluff pulp core and composite core. Composite core is a core structure widely used at present. The advantage of the composi...

AI Technical Summary

Problems solved by technology

[0006] 1) The diffusibility of the liquid in the composite core is poor, the utilization rate of the core is low, and the probability of leakage is relatively high when used at night, which may cause skin rashes and other problems

[0007] 2) The bottom of the absorbent core of existing diapers is closely attached to the leak-proof bottom film. When the urine volume is large, the core cannot absorb it instantly, causing the urine to extend to the left and right of the absorbent core, causing side leakage

[0008] 3) The diversion groove on the core spreads in one direction. When the urine volume is large, it cannot be absorbed in time, and the urine overflows the core along the diversion groove, resulting in leakage of urine and other problems
