Environmentally Friendly Antibacterial Cotton Textiles Finished with Siloxane Sulfopropylbetaine

Abstract

This paper reports a novel environmentally friendly antibacterial cotton textile finished with reactive siloxane sulfopropylbetaine(SSPB). The results show that SSPB can be covalently bound onto the cotton textile surface, imparting perdurable antibacterial activity. The textiles finished with SSPB have been investigated systematically from the mechanical properties, thermal stability, hydrophilic properties and antibacterial properties. It is found that the hydrophilicity and breaking strength are improved greatly after the cotton textiles are finished with SSPB. Additionally, the cotton textiles finished with SSPB exhibit good antibacterial activities against gram-positive bacteria Staphylococcus aureus (S.aureus, ATCC 6538), gram-negative bacteria Escherichia coli (E.coli, 8099) and fungi Candida albicans (C.albicans, ATCC 10231). Moreover, SSPB is nonleachable from the textiles, and it does not induce skin stimulation and is nontoxic to animals. Thus, SSPB is ideal candidate for environmentally friendly antibacterial textile applications.

Antibacterial Modification of Microcrystalline Cellulose by Grafting Copolymerization

“…This weight loss corresponded to the volatilization of water adsorbed or bounded on MCC . The second stage of weight loss began at 240 °C and was due to the decomposition of the macromolecular chain and the degradation of saccharide rings; Tmax in this stage was at 351 °C (Chen et al 2011;Liu et al 2014).…”

Regenerable Antibacterial Cotton Fabric by Plasma Treatment with Dimethylhydantoin: Antibacterial Activity against S. aureus

“…To achieve safety and health properties, antibacterial cotton fabric is grafted or coated with bactericides (e.g., chitosan, quaternary ammonium salts, chlorine and chloramines, etc.) [7][8][9][10][11], or loaded with heavy metal ions (silver, copper, zinc) [12][13][14][15]. However, it is found that the uptake and durability of these compounds are difficult to manage because they leach from the textiles easily [7].…”

However, it is found that the uptake and durability of these compounds are difficult to manage because they leach from the textiles easily [7]. These chemicals are always loaded onto cotton fabrics with the help of other chemicals, such as cross-linking agents, initiators, and catalysts, but the incompatibility of antibacterial agents with other chemicals and the toxicity of these antibacterial agents to humans and aquatic animals are also important weaknesses that need to be addressed [7].…”

In order to reduce chemical consumption, protect the environment, and improve the quality of textiles, researchers have worked hard to find innovative solutions.…”

Fabrication of Calcium Hydroxide-Cellulose Nanocomposites and Investigation on Their Physicochemical Characterisitics and Bactericidal Activities

“…Healthcare industries worldwide are considering it a global challenge in textile materials to make medicinal comfortable. Attempts have been made to meet this challenge using nanomaterials with a view to introducing new functional properties to healthcare textiles [16]. High performance of textile materials is greatly appreciated by a more discerning and demanding healthcare sector.…”
