Polyester masterbatch description:

Polyester masterbatch good temperature resistance, filtration performance, spinning cycle is long, with its excellent performance is widely used in polyester filament and staple fiber spinning before coloring. For high performance requirements of automotive interior fabrics, automotive interior fabrics masterbatch, the performance indicators excellent, widely used in the automotive industry.


Polyester masterbatch for use:
In actual spinning applications, according to different monofilament fineness filament shaped and slice properties (including light or extinction), etc., to adjust the proportion of masterbatch added and spinning processes. Recommended temperature controlled at 280 ~ 295 ℃. Polyester masterbatch has strong moisture absorption, it is recommended to use pre-dried before it, in order to avoid too much water into the melt, affecting the processing quality.
Polyester masterbatch add proportions and the relationship between single yarn fineness approximate conversion formula:

 
Where C: masterbatch added amount (%); d: single fineness (D / F)
