Abstract
Coating a cationic antibacterial layer on the surface of cotton fabric is an effective strategy to provide it with excellent antibacterial properties and to protect humans from bacterial cross-infection. However, washing with anionic detergent will inactivate the cationic antibacterial coating. Although this problem can be solved by increasing the amount of cationic antibacterial coating, excessive cationic antibacterial coating reduces the drapability of cotton fabric and affects the comfort of wearing it. In this study, a coordinated antibacterial coating strategy based on quaternary ammonium salt and a halogenated amine compound was designed. The results show that the antibacterial effect of the modified cotton fabric was significantly improved. In addition, after mechanically washing the fabric 50 times in the presence of anionic detergent, the antibacterial effect against Staphylococcus aureus and Escherichia coli was still more than 95%. Furthermore, the softness of the obtained cotton fabric showed little change compared with the untreated cotton fabric. This easy-to-implement and cost-effective approach, combined with the cationic contact and the release effect of antibacterial agents, can endow cotton textiles with durable antibacterial properties and excellent wearability.
Highlights
Breathable and comfortable cotton fabric is one of the most popular choices for clothing worn in daily life [1,2]
The results show that the cotton fabric obtained by this method had durable antibacterial activity after being washed 50 times in the presence of anionic detergent, and the antibacterial effect against both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) was more than 95%
To further finishing improve of cotton fabrics, many research groupsdecorative have devoted to creating antibacterial the added fabrics value of cotton Among fabrics, the many research groups have devoted themselves to creating for cotton antibacterial finishing agents, quaternary ammonium salt antibacterial finishing for cottonantibacterial fabrics [22,23,24]
Summary
Breathable and comfortable cotton fabric is one of the most popular choices for clothing worn in daily life [1,2]. Cotton benefits from its a high absorption ability and can absorb sweat, metabolites and sebum from the sweat/sebaceous glands of the skin. These secretions may provide a favorable environment for the growth of microorganisms such as bacteria and fungi [3]; these microorganisms can proliferate rapidly under certain conditions, and may pose a threat to public health. In order to effectively control the microorganisms and reduce possible bacterial infections, the introduction of antibacterial materials is an effective strategy to eliminate bacteria and avoid serious infections [4].
