Method for preparing strong-absorption antibacterial paper diaper

Abstract

The invention mainly relates to the technical field of hygiene products and discloses a method for preparing a strong-absorption antibacterial paper diaper. The method comprises the steps of surface layer preparation, Ag-activated carbon composite fiber layer preparation, water-absorption cotton preparation, water-absorption non-woven fabric preparation, core layer water-absorption layer preparation, bottom water-proof layer preparation and paper diaper preparation. By adopting the method for preparing the strong absorption antibacterial paper diaper, the paper diaper has strong hygroscopicity, achieves instant absorption, can prevent moisture of urine from soaking skin, is breathable and antibacterial, keeps skin to be dry and fresh, avoids generating the allergic phenomenon, and ensuressafety and health; the surface non-woven fabric is prepared by mixing fibers and performing spunlacing and is prepared from chitosan fibers, composite water-absorbent resin fibers, nano-antibacterialbioprotein fibers and silk fibers, so that the surface non-woven fabric can instantly absorb urine after contacting the urine and prevents itching and red rash since the urine contacts skin.

Description

technical field [0001] The invention mainly relates to the technical field of sanitary product processing, in particular to a preparation method of a strong absorption antibacterial paper diaper. Background technique [0002] With the change of people's living standards and living habits, diapers are used more and more widely. There are not only diapers for children, but also diapers for adults. At present, traditional diapers generally consist of the top layer without It is composed of woven fabric, the middle core layer and the bottom waterproof layer. Its structure is different from that of diapers. It is rectangular like diapers. It is thinner than diapers, and its water absorption is not as good as diapers. Therefore, it also limits the use and development of diapers. Therefore, it is necessary The utility model relates to a paper diaper with simple structure and strong water absorption.

[0002] With the change of people's living standards and living habits, diapers are used more and more widely. There are not only diapers for children, but also diapers for adults. At present, traditional diapers generally consist of the top layer without It is composed of woven fabric, the middle core layer and the bottom waterproof layer. Its structure is different from that of diapers. It is rectangular like diapers. It is thinner than diapers, and its water absorption is not as good as diapers. Therefore, it also limits the use and development of diapers. Therefore, it is necessary A disposable diaper with simple structure and strong water absorption

[0003] Existing paper diapers will produce obvious dampness after absorbing water, which is very easy to breed bacteria and have obvious peculiar smell. After long-term contact with the skin, the protective layer of the skin will be destroyed, causing skin allergies, itching and rashes, etc. It brings certain troubles to patients, so an antibacterial and hypoallergenic diaper is needed

[0004] The existing patent document CN102600020A discloses a composite core for sanitary products, specifically disclosing that the composite core consists of a non-woven fabric surface layer, a non-woven fabric bottom layer and a mixed middle layer of wood pulp fiber and polymer water-absorbing resin, and the mixed middle layer The layer is connected with the surface layer of non-woven fabric and the bottom layer of non-woven fabric through adhesive. The function of the mixed middle layer is to absorb the moisture penetrating from the surface layer of non-woven fabric, while the upper surface and lower surface of the mixed middle layer in the patent document are coated separately The adhesive is bonded to the non-woven fabrics on both sides, which affects the penetration of water from the surface layer of the non-woven fabric into the mixed middle layer, which obviously affects the water absorption effect of the mixed middle layer, and the use of adhesives can easily lead to skin allergies. have a greater impact on the safety and health of users

[0005] The existing patent document CN103550033A discloses a new type of strong-absorbent diaper, which specifically discloses that the diaper includes a water-permeable non-woven inner cover layer, a water-impermeable outer cover layer, and an absorbent core layer between the two , the absorbent core layer is composed of a dust-free paper layer, a superabsorbent layer, a fluffy body layer and an absorbent color-changing layer; the high-absorbent layer is made of pure wood pulp and superabsorbent resin, and the fluffy body layer is made of pure wood pulp and chemical fiber fleece The color-changing layer is composed of color-changing silica gel, pure wood pulp and superabsorbent resin; in the patent document, pure wood pulp is directly mixed with powdered superabsorbent resin, chemical fiber wool and color-changing silica gel. If the strength of the pulp decreases obviously, powder and slag will appear, which will have a great impact on human health.
