摘要
An antimony-free PET resin produced by using an inorganic Ti—Mg catalyst and a small amount of blue and red dyes, in the absence of an antimony catalyst or a phosphorus stabilizer; and, in a melt spinning process for producing PET polyester fiber, the PET resin demonstrates excellent spinnability but no yarn breaks or aggregation of TiO2 delustering agent so that the resultant PET polyester fiber features commercially desired in both color tone and glossiness. Especially the PET resin and the PET polyester fiber containing no antimony are therefore environmentally friendly by causing no heavy metal pollution to the environment.
