Abstract
The invention relates to a method for preparing a modified polyester fully drawn yarn with ultraviolet resistance, which comprises the preparation step of condensing and polymerizing modified polyester melt and the preparation process of directly spinning the polyester fully drawn yarn (FDY). In the preparation process of condensing and polymerizing modified polyester melt, the modified co-polyester melt is prepared from pure terephthalic acid (PTA) and ethylene glycol (EG) monomers as raw materials by adding nano zinc oxide. The polyester melt is directly transported through a melt, extruded through metering and spinning assemblies, cooled by blowing air, oiled and wound by a channel, a first yarn guide roller and a second yarn guide roller to prepare the modified polyester fully drawn yarn. The prepared fiber has good ultraviolet resistance, and the reflecting ability to ultraviolet rays reaches as high as 50-60%. The prepared fiber has stable contraction rate, uniform dyeing and excellent spinning performance.
