Problems solved by technology

[0003] 1. High cost;
[0004] 2. Polymer resin water-absorbing materials generally have the disadvantage of poor salt resistance
Therefore, the diaper products using it as a water-absorbing material still have defects such as not being able to absorb water for a long time, being used for a long time, and having poor air permeability.

Embodiment 1

[0031] Preparation of biological cellulose gel film by static fermentation method: use coconut water medium, inoculate Gluconacetobacter xylinum with an inoculum size of 8%, and after 5 days of static fermentation in a shallow plate at 28°C, harvest the organisms on the surface of the medium. The cellulose gel membrane is repeatedly washed with weak acid and deionized water to pH4 to remove the residual medium components and microbial cells attached to the biocellulose gel membrane. Then, the biocellulose gel film was cut into blocks by mechanical cutting method, dried at 50°C to constant weight, ground into powder, and wrapped in non-woven fabric to make an absorbent core layer.

[0032] Then use natural fiber or synthetic fiber as the surface covering layer, low-density polyethylene film as the bottom liner, and make paper diapers according to the known technology.

Embodiment 2

[0034]Preparation of biological cellulose gel by dynamic fermentation method: Use artificially prepared medium containing carbon source and nitrogen source to inoculate Gluconacetoacetobacter xylinum with an inoculum size of 10%. After 7 days of dynamic fermentation on a shaking table at 30°C, harvest the biological cellulose gel. Cellulose gel pellets are washed repeatedly with weak alkaline solution and deionized water to pH6 to remove residual medium components and microbial cells attached to the biocellulose gel. Mechanically compress to reduce the water content to 70%, then dry it to constant weight by vacuum freeze-drying, and grind it into powder. It is mixed with 5% (weight percentage) of acrylic water-absorbing resin, wrapped in non-woven fabric, and made into an absorbent core layer.

[0035] Then use natural fiber or synthetic fiber as the surface covering layer, low-density polyethylene film as the bottom liner, and make paper diapers according to the known technol...

Embodiment 3

[0037] Preparation of biological cellulose gel by dynamic fermentation method: Use artificially prepared medium containing carbon source and nitrogen source to inoculate Gluconacetoacetobacter xylinum with an inoculum size of 10%. After 7 days of dynamic fermentation on a shaking table at 30°C, harvest the biological cellulose gel. Cellulose gel pellets are washed repeatedly with weak alkaline solution and deionized water to pH6 to remove residual medium components and microbial cells attached to the biocellulose gel. Mechanically compress to reduce the water content to 60%, then dry it to constant weight by vacuum freeze-drying, and grind it into powder. It is mixed with 3% (by weight) coconut shell activated carbon, wrapped in non-woven fabric, and made into an absorbent core layer.

[0038] Then use natural fiber or synthetic fiber as the surface covering layer, low-density polyethylene film as the bottom liner, and make paper diapers according to the known technology.

Abstract

The invention relates to a paper diaper with good water-absorbing quality. The paper diaper with the good water-absorbing quality comprises a surface coating layer, an absorbing core layer and a bottom lining layer, wherein the absorbing core layer contains dried and dehydrated biological cellulose micro powder. The paper diaper with the good water-absorbing quality has the advantages of being good in water-absorbing quality, being breathable and having no discomfort when the paper diaper is used for a long time, and being biodegradable and environmentally friendly after being used.

Description

technical field [0001] The present application relates to a hygienic product, in particular to a diaper product used by infants or adults. Background technique [0002] Diapers are used by more and more consumers because of their disposable, lightweight and convenient features. It is generally composed of a surface covering layer, an absorbent core layer and a bottom lining layer. The surface covering layer is mostly made of non-woven fabric or cotton-like non-woven fabric, the base fabric is PE film or breathable PE film, and the absorbent core layer is mostly made of Wood pulp, fluff pulp, paper pulp and other water-absorbing materials are mixed with polymer water-absorbing resin. To achieve better water absorption performance, it is necessary to set a thicker size, which greatly affects the product quality. breathability and comfort. Moreover, after absorbing liquid, the absorbent core layer will be easy to agglomerate, and absorption faults will appear, thereby affecti...
