Introduction of Polyester Masterbatch:

Polyester masterbatch has good temperature resistance, excellent filtering performance, and long spinning cycle. With its excellent performance, it is widely used in the pre-spinning coloring of polyester filament and staple fiber. In response to the high performance requirements of automotive interior fabrics, automotive interior fabric masterbatches have excellent performance indicators and are widely used in the domestic automotive industry.

Instructions for use of polyester masterbatch

In actual spinning applications, the addition ratio of masterbatch and spinning processing technology should be adjusted according to different monofilament size, filament shape and slicing properties (including gloss or extinction), etc. It is recommended to control the temperature at 280~295℃. Polyester masterbatch has strong hygroscopicity. It is recommended to pre-dry it before use to prevent excessive water from being brought into the melt and affecting processing quality.
