Problems solved by technology

Although silver ions have excellent antibacterial activity, fabrics will be damaged to varying degrees in a strong alkaline environment
In addition, the price of silver is relatively expensive, and the cost is also a problem that cannot be ignored.

Abstract

The invention discloses a finishing method of a long-acting washable antibacterial fabric, and belongs to the field of textile engineering. The method comprises the steps that (1) a stable antibacterial siliceous body is prepared from organic-inorganic composite lipid with an antibacterial property; (2) a fabric is treated by a plasma treatment device and then soaked in an antibacterial siliceousbody solution for a grafting reaction; (3) the fabric subjected to the grafting reaction is washed with water and dried. By means of the method, after the fabric is subjected to surface grafting modification, the fastness and durability of fabric adsorption particles are improved, and the finished fabric belongs to a non-dissolution-out antibacterial fabric and is good in biocompatibility, ecologically friendly and excellent in washability.

Description

technical field [0001] The invention relates to the field of textile engineering, in particular to a long-acting washable and antibacterial fabric finishing method. Background technique [0002] The natural fibers that exist in nature mainly include cotton, hemp, silk and animal hair. Among them, the molecular components of cotton and hemp are mainly cellulose, while the molecular components of silk and wool are mainly proteins. Since natural fiber fabrics are mainly composed of polysaccharides and proteins, they are easily contaminated by bacteria and fungi, and their own antibacterial properties are not good. At present, the antibacterial finishing methods commonly used in industrial production all need to add antibacterial agents, and there are still some problems. For example: 1) Use natural antibacterial agents extracted and refined from animals and plants for antibacterial finishing. Due to the different properties of the extracts, there is no good general method fo...
