Calcite Added PP Fiber Production

Synthetic fiber production is one of the basic applications of the modern textile industry. However, increasing environmental concerns and sustainability requirements are forcing the sector to produce more environmentally friendly and innovative solutions. In this study, calcium carbonate (CaCO₃) additive was used in the production of polypropylene (PP) staple fiber. CaCO₃, a natural and renewable mineral, was added as a raw material to polypropylene production in order to ensure environmental sustainability, reduce production costs and improve fiber properties. Within the research scope of the project, it was decided to use CaCO₃ with high purity, special coating on the surface and stable particle size distribution. Using the compound production line, homogenous spreading of calcium carbonate in powder form into the PP matrix is one of the preliminary studies. During the fiber production trials, CaCO₃ was observed to improve processability, optimise extrusion pressure and prevent residue formation in spinnerets. In terms of fiber properties, positive effects such as opacity, static electrification resistance, textural improvements and industrial performance enhancement were noted. In addition, the cost advantage of the additive by reducing the use of TiO₂ and reducing the carbon footprint are important findings. The thermal conductivity-enhancing effect of calcium carbonate decreases the processing temperature range, resulting in energy savings in production processes. Moreover, thanks to its compatibility with recycling processes, polypropylene nonwovens containing CaCO₃ can be reprocessed without loss of performance and improve homogeneity. These properties increase industrial functionality and sustainability while reducing the environmental impact of polypropylene products. In the project outputs carried out as Telasis Tekstil, it is seen that the use of calcium carbonate in polypropylene fiber production offers an innovative approach to reducing environmental impacts and improving product quality. The study can inspire manufacturers and researchers to develop sustainable textile solutions.
