By detecting the polyester masterbatch, it is possible to roughly predict the replacement cycle of the relevant spinning component, which sounds a bit ridiculous, but in fact it is valid, please continue to look down.

Since polyester fiber raw material spinning is used for fine fiber, it is necessary to meet the requirements of spinning spinneret replacement cycle. Therefore, the high-grade oil-soluble dye used for polyester fiber raw liquid spinning is chemically purified, and its ash content is up to standard. . In the process of using polyester masterbatch, polyester fiber companies must be tested and tested on polyester masterbatch to see if the specifications of polyester masterbatch are up to standard.

For example, check the DF value (or △ P curve), so that the actual filtration performance of the masterbatch can be determined. The value can predict the spinning cycle replacement cycle of the polyester filament manufacturer, which is very good for producing high quality tows in the future. The benefits. Because, after all, the quality of the products produced by the spinning posts due to the untimely replacement of components is not enough, and can not be ignored.
