Bonding ability of chitosan with synthetic fabrics

To investigate the bonding state of antibacterial finished synthetic fabric using chitosan,modified chitosan antibacterial liquids were prepared with modified quaternary ammonium salt of chitosan(HTCC) using three different processes and formulas.The paper selected acrylic knitted fabric and vinylon packing bag as samples and finishing of the samples was carried out with the modified chitosan antibacterial liquids.Scanning electron microscopy and Fourier transform infrared spectroscopy were used to examine the adsorptive bonding of modified chitosan with the fiber.The results showed that modified quaternary ammonium salt of chitosan with acrylic fabric and vinylon fabric had respectively undergone adhesion combination under the action of adhesive agent system.The adsorption of modified chitosan on fabric surface was confirmed.Consequently,the purpose of antibacterial finishing of synthetic fabrics using modified chitosan was achieved.
