Problems solved by technology

The chitosan film formed after dissolving chitosan in acetic acid and then drying has a good antibacterial effect, but this film is brittle and impermeable. If it is covered on the surface of sanitary napkins, it will seriously affect the flexibility of sanitary napkins Degree and absorbency, while improving the antibacterial performance of sanitary napkins, it will damage the proper functions of sanitary napkins

Embodiment 1

[0032] Weigh 1 g of chitosan with a molecular weight of 2000 KDa and a degree of deacetylation of 85%, add 200 ml of water and 0.5 ml of acetic acid, and stir evenly to obtain a chitosan-acetic acid solution.

[0033] Weigh 1 g of fish collagen, add 200 ml of water and 1 ml of acetic acid, and stir evenly to obtain a fish collagen acetic acid solution.

[0034] Add 10% (v / v) fish collagen acetic acid solution by volume to the chitosan acetic acid solution, stir in a constant temperature water bath at 40° C. for 30 minutes, and wait for the liquid to cool to room temperature.

[0035] Add 10% (v / v) glycerin by volume to the liquid cooled to room temperature, stir evenly, and then ultrasonically degas for 40 minutes to form a liquid chitosan preparation.

[0036] The liquid chitosan preparation is added to the sanitary napkin by soaking, so that the chitosan preparation covers the surface of the sanitary napkin, and the excess chitosan liquid on the surface of the sanitary napki...

Embodiment 2

[0043] Weigh 1 g of chitosan with a molecular weight of 1500 KDa and a degree of deacetylation of 80%, add 500 ml of water and 1 ml of acetic acid, and stir evenly to obtain a chitosan acetic acid solution.

[0044] Weigh 1 g of fish collagen, add 500 ml of water and 1 ml of acetic acid, and stir evenly to obtain a fish collagen acetic acid solution.

[0045]Add 5% (v / v) fish collagen acetic acid solution by volume to the chitosan acetic acid solution, stir in a constant temperature water bath at 40° C. for 20 minutes, and wait for the liquid to cool to room temperature.

[0046] Add 5% (v / v) glycerin by volume to the liquid cooled to room temperature, stir well and then ultrasonically degas for 30 minutes to form a liquid chitosan preparation.

[0047] The liquid chitosan preparation is added to the sanitary napkin by spraying, so that the chitosan preparation covers the surface of the sanitary napkin, and the excess chitosan liquid on the surface of the sanitary napkin is dr...

Embodiment 3

[0052] Weigh 1 g of chitosan with a molecular weight of 68.6 KDa and a degree of deacetylation of 85%, add 200 ml of water and 0.5 ml of acetic acid, and stir evenly to obtain a chitosan-acetic acid solution.

[0053] The chitosan acetic acid solution is added to the sanitary napkin by soaking, injecting or spraying, so that the chitosan preparation covers the surface of the sanitary napkin, and the excess chitosan liquid on the surface of the sanitary napkin is drained.

[0054] The sanitary napkin added with the chitosan acetic acid solution was dried at 50° C. for 24 hours, and then cooled to room temperature to obtain a sanitary napkin covered with the chitosan acetic acid solution.

[0055] The chitosan preparation and chitosan acetic acid solution obtained in the above example 1 are added to the sanitary napkin by soaking, spraying and injecting, the immersion method: the addition amount covers the sanitary napkin surface, the spraying method: the addition amount covers t...

Abstract

The invention belongs to the field of technical processing and application of ocean resource natural products and in particular relates to a preparation for improving antibacterial performance of a sanitary napkin and an antibacterial method of the preparation. The preparation comprises a main material or a main material and auxiliary materials, wherein the main material is chitosan; the auxiliarymaterials are fish collagen or fish collagen and glycerinum; the molecular weight of the chitosan is 10-2000KDa; and the degree of deacetylation is 80-100%. The preparation provided by the inventionis low in price, small in amount, safe and convenient, free of toxic or side effect and small in product cost influence, the antibacterial performance of the sanitary napkin can be greatly improved, and original absorption performance and flexibility of the sanitary napkin are not changed.

Description

technical field [0001] The invention belongs to the technical processing and application field of natural products of marine resources, and in particular relates to a preparation for improving the bacteriostatic performance of sanitary napkins and a bacteriostatic method thereof. Background technique [0002] Candida albicans is also known as Candida albicans and Candida albicans. Candida is a type of Candida, usually present in the oral cavity, upper respiratory tract, intestinal tract and vagina of normal people, generally in a small number in the normal body, and does not cause disease. Imbalance, the bacteria reproduce in large numbers and change the growth form (sprout mycelial phase) to invade cells and cause diseases. Candida albicans can cause vaginitis if it multiplies in large numbers in the vagina. [0003] As the deacetylation product of natural polysaccharide chitin, chitosan has many excellent physical and chemical properties, such as biocompatibility, biodeg...
