Traditional textiles provide a growth environment for microorganisms such as bacteria. These harmful microorganisms can cause a range of adverse effects on the textile itself and on the wearer, including unpleasant odors, stains and discoloration. What's more, some pathogenic bacteria that exist on the surface of the fabric can even cause heart problems and pneumonia after direct contact with the human body. These problems have promoted the development of antibacterial textiles. Colloidal nanomaterials have attracted more and more attention as antibacterial agents for antibacterial textiles. Alfa Chemistry is able to modify fabric surfaces with colloidal materials and study their antibacterial efficacy.

Research and Practice of Colloids in Antibacterial Textiles

The introduction of antibacterial agents into textiles can prevent the growth of bad pathogenic strains and play an antibacterial effect. But the repeated use of natural antibacterial agents leads to drug resistance in pathogenic strains, and chemical disinfectants are toxic to the environment and humans. The high surface area-to-volume ratio of colloidal particles, such as metals, metal oxides, and colloidal composites, enhances their interactions with microorganisms and is found to have antibacterial activity. Therefore, these colloidal particles can be added to textile fabrics as antibacterial agents to eliminate the growth and spread of bacteria.

Some researchers used ultrasonic irradiation to irradiate copper acetate solution impregnated with cotton fabrics, and directly synthesized CuO colloidal particles on textile materials in situ, as shown in Fig.1. The textile exhibits long-lasting antibacterial properties. While there are many theories about the antibacterial mechanism of colloidal particles, and Fig.2 summarizes the antibacterial mechanisms that colloidal particles may exhibit.

Alfa Chemistry is able to incorporate recent advances in the field of colloidal material structure into textile applications, using them as potential reagents to avoid the spread of pathogenic bacteria. We specialize in chemically incorporating colloidal particles into fabric surfaces and are able to provide methods for evaluating antimicrobial efficacy.
