Embodiment 1

[0026] An antibacterial cotton cloth made by the following method:

[0027] (1) Take 2% silver-loaded hydroxyapatite, 0.1% sodium hexametaphosphate, 5% chitin, and 0.05% citric acid according to mass percentage, and add water to 100% to make a solution;

[0028] (2) Put the medical absorbent cotton cloth into the solution prepared in step (1) for padding, padding twice, with a rolling margin of 100%, pre-baking at 90°C for 2 minutes, and then baking at 150°C for 3 minutes to make Antibacterial cotton cloth.

[0029] The silver-loaded hydroxyapatite was prepared in Example 5.

Embodiment 2

[0031] An antibacterial cotton cloth made by the following method:

[0032] (1) Take 1% of silver-loaded hydroxyapatite, 0.2% of sodium hexametaphosphate, 8% of chitin, and 0.1% of citric acid according to mass percentage, and add water to 100% to make a solution;

[0033] (2) Put the medical absorbent cotton cloth into the solution prepared in step (1) for padding, padding once, with a rolling margin of 90%, pre-baking at 80°C for 1 min, and then baking at 130°C for 4 min to make Antibacterial cotton cloth.

[0034] The silver-loaded hydroxyapatite was prepared in Example 6.

Embodiment 3

[0036] An antibacterial cotton cloth made by the following method:

[0037] (1) Take 3% silver-loaded hydroxyapatite, 0.05% sodium hexametaphosphate, 6% chitin, 0.02% citric acid according to mass percentage, and add water to 100% to make a solution;

[0038] (2) Put the medical absorbent cotton cloth into the solution prepared in step (1) for padding, padding twice, with a rolling margin of 60%, pre-baking at 100°C for 3 minutes, and then baking at 170°C for 1 minute to make Antibacterial cotton cloth.

[0039] The silver-loaded hydroxyapatite was prepared in Example 7.

Abstract

The invention discloses an antibacterial cotton cloth and a preparation method thereof. The antibacterial cotton cloth is produced by the following method and the method comprises the following steps: adding the silver-carrying hydroxylapatite, sodium hexametaphosphate, deacetylated chitin and citric acid into the water to form a solution; placing an absorbent cotton cloth into the solution prepared by the step (1) for padding and the residual padding rate is 60-100%, then pre-baking for 1-3 minutes at the temperature of 80-100 DEG C and then baking for 1-4 minutes at the temperature of 130-170 DEG C, therefore, the antibacterial cotton cloth can be produced. The invention adopts the silver-carrying hydroxylapatite which has broad antibacterial spectrum and good compatibility with the human body as the antibacterial finishing agent, therefore, the cloth is highly safe; the molecule of the silver-carrying hydroxylapatite contains a hydroxy base group that can produce acting force with the cellulose molecule, thus being capable of improving the binding strength between the antibacterial finishing agent and the cotton gauze; and the cloth has good washing fastness; The antibacterial cotton cloth of the invention contains antibacterial finishing agent that can kill or restrain the growth of the bacteria, and simultaneously keeps the good permeability, moisture absorption property and softness of the cotton cloth.

Description

Technical field [0001] The invention relates to a cotton cloth and a preparation method, in particular to an antibacterial cotton cloth and a preparation method. Background technique [0002] Ordinary cotton cloth is composed of cotton fiber material, and bacteria are easy to attract and breed on this fiber. Ordinary cotton cloth does not have antibacterial and sterilization effect, and can only play a role in shielding bacteria. [0003] Antibacterial cotton cloth is obtained after antibacterial finishing of ordinary cotton cloth. This finishing technology imparts antibacterial properties to the cotton gauze material itself and improves the antibacterial ability of the material itself, so that the material can resist or kill bacteria while shielding bacteria. This can effectively reduce the wound infection rate of wounds wrapped by cotton cloth. [0004] The existing antibacterial cotton fabrics are mainly divided into two categories according to the antibacterial finishing agen...
