Paper diapers with excellent water-absorbing and antibacterial properties and their processing technology

Abstract

The invention relates to a processing technology of a diaper, which comprises a diaper main body. The diaper main body is provided with a surface layer, a flow guide layer, an absorbent core layer and a bottom film layer sequentially from top to bottom, and the absorbent core layer is arranged from bottom to top. It includes a dust-free paper layer and a superabsorbent material layer in sequence, and the superabsorbent material layer is processed by mixing antibacterial superabsorbent resin microspheres and fluff pulp in a mass ratio of (3-4):(7-6). The antibacterial polymer water-absorbing resin microspheres used in the diapers of the present invention, its synthesis method is an improvement of the method for synthesizing polymer water-absorbing resin by the solution method, adding magnetically ordered mesoporous carbon nanospheres with multi-channel, regular pore diameter, and large specific surface area. The ball is used as a carrier to improve the efficiency of the polymerization reaction, the product polymer water-absorbing resin microspheres have uniform properties, and the post-treatment process is simple.

Description

technical field [0001] The invention relates to a diaper with excellent water-absorbing and antibacterial properties and a processing technology thereof, belonging to the technical field of diaper processing. Background technique [0002] Diapers are disposable products that can be discarded after use. Made of non-woven fabric, polymer water-absorbing resin, PE film and other materials, the diaper generally includes a diaper body and baffles arranged longitudinally on both sides of the diaper body in terms of structure. Provided topsheet, absorbent core layer and backsheet. The core layer is called the heart of diapers, and the quality of diapers with different cores varies greatly. The core of the water absorption performance of the core is the amount and distribution of the polymer water-absorbent resin SAP. The core contains a large amount of SAP to ensure the water absorption of the diaper, and the overall expansion after absorbing water. [0003] Superabsorbent resin...

Problems solved by technology

Among them, the solution method is simple to implement, but the properties of the product lead to complicated post-treatment procedures, high energy consumption and high cost

The particle size of the resin particles prepared by the inverse suspension method is small and does not require crushing treatment, but the purity is not high, which affects its industrial application; the particle size of the resin particles prepared by the inverse emulsion method is smaller than that prepared by the inverse suspension method, and the particle size If it is too small, the water absorption performance will decrease, dough phenomenon will appear, and the water absorption rate will also be significantly reduced. It is not suitable for the core of diapers. The maximum water absorption of the resin prepared by the conventional dispersion method is small.

[0005] There are various types of polymer water-absorbent resins in the prior art, some of which have been successfully applied to the core of diapers, but they still have the following deficiencies: the maximum water absorption rate, water absorption rate, water-locking effect and avoiding the phenomenon of dough. Important elements are difficult to balance
