Introduction of Polyester masterbatch :

Polyester masterbatch  has good temperature resistance, excellent filtration performance and long spinning cycle. It is widely used in the dyeing of polyester filament and staple fiber before spinning due to its excellent performance. According to the high performance requirements of automotive interior fabric, automotive interior fabric color master, excellent performance indicators, widely used in the domestic automotive industry.

Instructions for use of polyester masterbatch 

In the actual spinning application, the proportion of master particles added and the spinning process should be adjusted according to the different monofilament size, filament shape and slice properties (including light or extinction). The recommended temperature range is 280 ° C to 295 ° C. Polyester colored masterbatch has strong hygroscopicity, it is recommended to pre-dry it before use, so as to avoid excessive water into the melt, affecting the quality of processing.
