Polyester masterbatch introduction:
Polyester color master is well temperature resistance, excellent filtration performance, long spinning period, is widely used in polyester filaments and short-filament coloration. For high performance requirements of automotive interior fabrics, automotive interior cloth masterbatch, excellent performance indicators, widely used in the domestic auto industry.
Polyester masterbatch instructions
In actual spinning applications, the addition ratio of the masterbatch and the spinning process of the spinning process should be adjusted according to different monofilates, filament and slice performance (including light or mesh), and the like. It is recommended to use temperature control at 280 to 295 ° C. Polyester colored masterbill has strong hygroscopicity, it is recommended to prepare it to prepare it to avoid overproduction to the melt, affecting processing quality.
