The production of PP raffia starts with pp raffia granules, which are small, uniform pellets made of polypropylene. These granules serve as the raw material. They are carefully prepared and fed into the extruder hopper. The feeding process ensures a steady and controlled supply of granules for melting. Temperature settings in the extruder range from about 200°C to 250°C, depending on the specific grade, such as Marlex PP raffia, to achieve optimal melting without degrading the polymer.
Once melted, the polypropylene flows through a spinneret, which shapes the molten polymer into thin, continuous filaments. These filaments cool and solidify rapidly. The extrusion aligns the polymer molecules, which is crucial for enhancing the fibers’ strength and flexibility. This stage transforms pp raffia granules into long, fine fibers ready for further processing.
The continuous filaments are then twisted and texturized to mimic the natural structure of raffia fibers. Twisting increases the fiber’s tensile strength and durability, while texturizing adds bulk and improves flexibility. Drawing, or stretching, further aligns the polymer chains, enhancing mechanical properties like tensile strength and impact resistance. These techniques adapt the fibers to their final use, whether woven into fabric or braided into ropes.
After texturizing, the fibers are wound onto large spools or bobbins. This winding process prepares the fibers for weaving or braiding. Proper tension control during winding is vital to prevent fiber damage and maintain uniformity. Spooling also facilitates easy handling during the next manufacturing stages.
The spooled fibers are woven or braided depending on the intended application. Weaving interlaces the fibers to form flat, fabric-like sheets commonly used for bags and sacks. Braiding creates round or tubular structures suitable for ropes and twines. Both methods contribute to the high strength and durability of PP raffia products.
Finally, the woven or braided PP raffia undergoes finishing treatments. Coatings may be applied to improve water resistance and abrasion protection.
