Problems solved by technology

Chung-Feng et al published the article A study on blending polyethyleneterephthalate with titanium dioxide particles in melt spinning process parameter optimization (2012, 83, 813-826) on Textile Research Journal, by directly mixing titanium dioxide nanoparticles into PET melt spinning PET / titanium dioxide composite fibers were prepared in the liquid, and they found that when the content of titanium dioxide reached 1%, titanium dioxide could be well dispersed in PET, but when the content of titanium dioxide reached 5% of the mass of PET, there would be serious agglomeration. So people began to explore how to improve the dispersion of inorganic nano-titanium dioxide in polymers

Abstract

The invention discloses a method for preparing an antibacterial polyethylene glycol terephthalate composite fiber membrane. The method comprises the following steps of: adopting bisphenol A-type phenoxy resin as dispersant, blending the bisphenol A-type phenoxy resin with a polyethylene glycol terephthalate slice and titanium dioxide nanometer powder, and then electro-spinning to obtain the polyethylene glycol terephthalate composite fiber membrane with antibacterial function. According to the method, the bisphenol A-type phenoxy resin is adopted as the dispersant, so that a shortcoming that titanium dioxide particles are gathered in the polyethylene glycol terephthalate is overcome; the method has the advantages of low cost, simple method and stable performances; and meanwhile, the toughness of the bisphenol A-type phenoxy resin is good, so that the mechanical performance of the fiber membrane is improved.
