Abstract

The invention discloses a textile antibacterial agent and application thereof. The textile antibacterial agent is prepared from the following components in parts by weight: 1.5-7.5 parts of water-soluble chitosan, 1.5-2 parts of juniperus chinensis oil, 2-4 parts of a sappan wood extract, 8-12 parts of a pH regulator and 100-150 parts of water; a preparation method comprises the steps that juniperus chinensis is distilled for 3-4 h in a 1 wt%-2 wt% sodium chloride solution according to the material-liquid ratio of 1 g: 6 mL to obtain the juniperus chinensis oil; dried heartwood of sappan woodis mashed and decocted, then is extracted with a 50 wt.%-60 wt.% ethanol solution and is centrifugally separated after extraction, and a supernatant is concentrated to obtain the sappan wood extract;and after the antibacterial agent components are prepared in parts by weight, the water-soluble chitosan is mixed into water, uniformly stirring is conducted under a continuous heating condition, andstirring is conducted at a constant temperature for 15-20 minutes under a boiling condition; and heating is stopped, the juniperus chinensis oil and the sappan wood extract are added when the temperature is reduced to 40-50 DEG C, the pH regulator is added afteruniformly stirring, and uniformly stirring is conducted at room temperature. The antibacterial agent can achieve broad-spectrum antibiosis, is not prone to generating drug resistance, and is good in durability.

Description

technical field [0001] The invention belongs to the field of textile antibacterial technology, and in particular relates to a textile antibacterial agent and its application. Background technique [0002] Textiles can absorb sweat, sebum and other excretions secreted by the human body. In an environment with suitable temperature and humidity, microorganisms living on textiles can reproduce in large numbers, decompose human secretions, and produce odorous substances such as ammonia. The formation of bacterial plaque can cause discomfort or adverse effects on the human body during wearing or application, causing mildew, embrittlement or even deterioration of textiles. With the development of society and the improvement of people's living standards, new market demands have emerged. Consumers hope that textiles have antibacterial functions to meet the needs of a civilized and comfortable life. [0003] Antibacterial fabric refers to the use of various antibacterial agents to pe...
