Fibrillated and Split Film Yarn Systems
topic
Fibrillated tape yarn production mechanically fibrillates drawn tape yarn through needle roller or twisted blade treatment that splits the tape into a network of interconnected fibrils creating a three-dimensional yarn structure with improved cover and bulk compared to flat tape, producing the fibrous polypropylene yarns used for secondary carpet backing, erosion control blankets, and agricultural twine requiring greater bulk and moisture absorption than flat tape yarns.
Role
Creates fibrous three-dimensional yarn structures from flat tape through mechanical fibrillation that improves the cover, bulk, and processability of polypropylene tape yarn for applications requiring greater fabric cover and inter-yarn cohesion than flat tape yarn provides, with fibrillation treatment being the value-adding step that differentiates premium agricultural and technical polypropylene yarns from commodity flat tape alternatives.
