Tape Yarn and Film Splitting Technology
topic
Tape yarn production slits extruded polymer film into narrow tapes of 1 to 5 millimetres width using rotary knife or laser slitting, optionally fibrillating the slit tape by mechanical pin roller or air jet treatment that splits the tape into a network of interconnected fibril bundles, producing polypropylene tape yarns for woven bags, geotextiles, and carpet backing at very low cost per kilogram.
Role
Provides the lowest-cost textile yarn manufacturing route by converting commodity polymer film into tape or fibrillated yarn without fibre spinning, achieving production rates and raw material costs per kilogram far below any staple or filament spinning technology, making tape yarns the economic material of choice for high-volume, low-cost technical applications in packaging, geosynthetics, and secondary carpet backing.
