Abstract

The invention discloses a preparing method for an activated aluminum oxide based anti-microbial film for fabrics. The preparing method comprises the steps that polyaniline is added in dimethyl formamide to be evenly stirred, dissolving liquid is formed, absolute ethyl alcohol is added, and viscous fluid is formed; tourmaline powder is added in the viscous fluid to be subjected to ultrasonic dispersion for 2-4 h, constant-temperature ultrasonic treatment is conducted for 20-30 min, and spinning liquid is obtained; the spinning liquid is added in an electrostatic spinning machine to be subjectedto high-voltage electrostatic spinning, and fiber monofilaments are obtained; then, the fiber monofilaments are woven to form a fiber net; aluminum hydroxide is evenly dispersed in the absolute ethylalcohol, and good turbid liquid is formed; and the surface of the fiber net is evenly coated with the dimethyl formamide, a liquid film is formed, the surface of the liquid film is evenly coated withthe turbid liquid, standing is conducted for 10-20 min, constant-temperature drying is conducted, and the anti-microbial film is obtained. Tourmaline powder negative ions are utilized for being combined with an activated aluminum oxide oxygen-rich system, negative oxygen ions can be formed through rapid combination, the anti-microbial effect is achieved, and physical and psychological health canbe benefited as well.

Description

technical field [0001] The invention belongs to the field of fabrics and relates to antibacterial fabrics, in particular to a preparation method for fabrics based on active alumina antibacterial films. Background technique [0002] Antibacterial fabric is a special functional fabric with good safety. It can efficiently and completely remove bacteria, fungus and mold on the fabric, keep the fabric clean, and prevent bacteria from regenerating and multiplying. Antibacterial fabrics have a good antibacterial effect, can eliminate the peculiar smell caused by bacteria, keep the fabric tidy, and avoid the reproduction of bacteria to reduce the risk of re-spread. Main application directions: socks, underwear, tooling fabrics, outdoor sports fabrics, etc. With the continuous improvement of people's living standards, people's pursuit of the comfort and functionality of clothing is getting higher and higher, so the demand for antibacterial materials and antibacterial clothing is inc...
