Abstract
The invention relates to a method for preparing a nano-ZnO (zinc oxide) modified polyester pre-oriented yarn. The method comprises preparation of modified polyester melt and preparation of direct-spun polyester pre-oriented yarn (POY); and in the process of preparing a modified polyester melt, a pure terephthalic acid (PTA) and an ethylene glycol (EG) monomer are taken as raw materials, and a nano modifier is added so as to prepare a modified copolyester melt, then the polyester melt is directly conveyed by a melt, and through carrying out metering, spinning assembly extrusion, air blast cooling, oil applying, channel passing, and winding on the polyester melt, a nano-ZnO modified polyester pre-oriented yarn is obtained. A fiber prepared by using the method provided by the invention has a good ultraviolet-resistant function, and the ultraviolet reflection capacity of the fiber is as high as 50-60%.
