Relevant Production Parameters for the Colored Masterbatches and Comparison of the Internal and External Types

Characteristics of colored masterbatches have great effects on the quality of synthetic fibers. In this research work, the necessary suitable characteristic of the colored masterbatches for synthetic fibers have been studied. Two methods for characterization of internal and external masterbatches were used. In the first method a brabender internal mixer was used and parameters such as total energy, steady state energy, maximum torque, steady state torque were studied. Due to lack of knowledge of the formulation for the used masterbatches, this method was unable to provide an accurate evaluation for the quality of the masterbatches produced by different manufacturers. But it could be a useful method for evaluating the quality of masterbatches for a known manufacturer. The second method is based on optical microscopic analysis of the micrographs, which is a suitable criterion for qualitative analysis of the colored masterbatches. By optical analysis of the micrographs a quantitative criterion can be obtained.
