polyester masterbatch introduction:
polyester masterbatch good temperature resistance, excellent filtration performance, long spinning cycle, with its excellent performance widely used in polyester filament and staple fiber before spinning coloring. in view of the high performance requirements of automotive interior fabrics, automotive interior cloth masterbatch, the performance indicators are excellent, widely used in the domestic automotive industry.
polyester masterbatch instructions
in the actual spinning applications, should be based on different monofilament fineness, filament and slice performance (including light or extinction), etc., to adjust the proportion of masterbatch and spinning process. it is recommended to use temperature control at 280 to 295 ° c. polyester coloring masterbatch has a strong hygroscopicity, it is recommended to use it before the pre-drying, so as not to bring too much water into the melt, affecting the quality of processing.
