Study Of Antibacterial And Dyeing Property Of Antibacterial PET/PA Microfiber

In this paper, the optimum splitting technology conditions of antibacterialPET/PA composite microfiber was determined by orthogonal experiment interms of decrement rate and antibacterial effect; the antibacterial activities,antibacterial durability and color changing property of splitting antibacterialmicrofiber under the optimized splitting process were evaluated. Thecomprehensive test results showed that antibacterial PET/PA compositemicrofiber has very good antibacterial and antitarnishing properties.A series of experiments have also been done on dyeing capacity ofantibacterial PET/PA composite microfiber, which was evaluated in this researchby contrast with conventional PET/PA composite microfiber, PET microfiberand PET fiber.We have carried out experiments on thermodynamics and kinetics of dyeingantibacterial PET/PA composite microfiber employing disperse red FB. Dyeingcapacity of antibacterial PET/PA composite microfiber is shown by the results ofexperimentation such as affinity of dyeing, heat of dyeing, entropy of dyeing,diffusion coefficient, half-dyeing time, constant of dyeing rate and so on. Andthis paper has made clear why there are such differences between antibacterialPET/PA composite microfiber and conventional PET/PA composite microfiber,PET microfiber as well as PET fiber on dyeing capacity from the point ofaddition of antibacterial agent, linear density and component of fiber.
