Abstract


As one kind of delustrants, TiO2（ Titanium Dioxide） is often adopted to lighten the color in polyester production. But the domestic made TiO2 quality can not reach the standard as polyester industry demanded. Since the lack of the special treated TiO2 for polyester industry, the polyester production mainly relies on imported TiO2. There’s much space to develop the domestic made TiO2 used in polyester industry.Co-operating with Hebei Huierxin Co, Tianjin Petrochemical Co.Polyester Dept. analyzed the TiO2 quality indicators, started to production in the sequential polyester filature instrument, then test in the new zone and FDY instrument, at last adopted their TiO2 in all the new zone instruments. After the analysis on the results, I am confirmed that I aquire the basic experiment data and accumulat many industrialized experiences.The results also prove that the domestic made fibre class TiO2 produced by Hebei Huierxin Co. has almost reached the quality level comparing with those imported products. The Huierxin TiO2 can be used in the polyester production, can be used to replace the imported TiO2. By the decreased cost, we promote our competition ability on the polyester products.One the other hand, there are some fields to be developed for our domestic made TiO2. Comparing with the imported products, the color is not that satisfied, the filter and floccus indicators should be improved in the future.
