Nylon textiles grafted with chitosan by open air plasma and their antimicrobial effect

Abstract

Chitosan is a natural non-toxic biopolymer and is widely used in various fields because of the antimicrobial activities. In this study, the properties of nylon textiles grafted with chitosan oligomer or chitosan polymer after being activated by open air plasma were evaluated. Results showed that nylon textiles grafted with chitosan polymer had better antibacterial performances than those grafted with chitosan oligomer. Air plasma activation at a higher speed (26 m/min) for a few times facilitated the grafting of chitosan and critically determined the antibacterial activities. Further treatment with air plasma after grafting improved the antibacterial effect. Overall, chitosan-grafted nylon textiles showed good antibacterial potential as well as biocompatibility

Emerging Green Technologies and Environment Friendly Products for Sustainable Textiles

“…Hegemann et al [56] reported the development of multifunctional textiles by use of nanostructured plasma coatings. Tseng et al [57] reported the grafting of chitosan oligomer and biopolymer onto nylon textiles previously activated by open air plasma. It was found that nylon grafted with chitosan polymer had better antimicrobial properties than nylon grafted with chitosan oligomer.…”

Antimicrobial Modifications of Polymers

“…This method demands low pressure (0.1 -100 Pa) and the presence of a working gas (usually N 2 , O 2 or Ar, CF 4 ). Plasma modifications to polymer surfaces are characterized by their weak stability over time, as polymer surfaces tend to return to their original chemical state [30][31][32][33][34][35][36][37][38][39][40].…”

“…In vitro cytotoxicity test is a useful technique for detecting such agents using the yellow tetrazolium salt (MTT) assay [31,32].…”

“…For each cell type a linear relationship between cell number and absorbance is established, enabling accurate, straightforward quantification of changes in proliferation. Tseng et al [32] used L929 cells extracted from the male mouse for testing the cytotoxicity of a nylon-chitosan composite material after curing by air plasma machine. The L929 cell line was used for this work.…”
