Application of the Desirability Function for Optimizing the Use of Calcium Carbonate Used in the Production Process of PVC-Coated Textile

The application of calcium carbonate (CaCO3) particles as functional fillers has been a judicious idea for many industrial plastic products in recent years. This paper deals with an evaluation of the quality of coated textiles used as a furnishing article, by changing the amount and the size of calcium carbonate particles using the desirability function. Referring to the literature studies, the desirability function remains an appropriate method that allows a level of flexibility over a graphical tool in defining and evaluating quality. It was concluded that the ideal mechanical properties of polymeric layers used for PVC furnishing articles (breaking load, tearing strength, elongation to break, and abrasion resistance) largely depend on calcium carbonate amount and particle size where the smallest particle size gave the highest values compared to the others. For the content effect analysis, the applied contents influenced mechanical properties significantly.
