For polyester fiber users who use polyester masterbatch, it is important to know if the polyester masterbatch they use meets their quality standards. Because the main function of polyester masterbatch is coloring, its color and color fastness must meet the requirements of polyester fiber users, and its quality must also meet the requirements of polyester spinning and post-processing, that is, not because of polyester masterbatch. The addition of the granules affects the spinnability of the polyester and the physical and mechanical properties of the colored fibers.

Therefore, polyester fiber manufacturers must use polyester masterbatch with uniform particle size, no dust, no debris and no ultra-long particles; the bulk density should be stable and accurate, and the particle size should be as consistent as possible with the spinning raw material slice, dry polyester masterbatch Grain and so on.

The above summary hopes to provide you with a reference.
