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.
