Preparation and antibacterial properties of copper phthalate/polyethylene terephthalate composition fiber

Copper phthalate was employed as antibacterial agent that improve its dispersibility in polyethylene terephthalate (PET) fiber. The antibacterial activity of copper phthalate, copper terephthalate and nano-copper oxide were evaluated against Colon bacillus, Staphylococcus aureus and Candida albicans...

Zusammenfassung:Copper phthalate was employed as antibacterial agent that improve its dispersibility in polyethylene terephthalate (PET) fiber. The antibacterial activity of copper phthalate, copper terephthalate and nano-copper oxide were evaluated against Colon bacillus, Staphylococcus aureus and Candida albicans, copper phthalate showed the best antibacterial activity. The antibacterial masterbatch of copper phthalate was subsequently prepared by melt blending, which integrated into PET to prepare antibacterial fiber during the spinning process at 285 °C. The sample containing 0.3 % copper phthalate displayed great antibacterial performance and durability against Escherichia coli, Staphylococcus aureus and Candida albicans.
