Polyester Staple Fiber (PSF)
technoPET specializes in the international sourcing and marketing of high-grade Polyester Staple Fiber (PSF). We offer both Virgin PSF (synthesized from PTA & MEG or virgin PET polymer) and Recycled PSF (extruded from cleaned post-consumer PET flakes). Our range includes Solid Fiber for ring spinning and open-end yarn manufacturing, as well as Hollow Conjugated Siliconized (HCS) and Non-Siliconized (HC) fibers engineered for high-loft cushioning, mattress pads, pillows, plush toys, and thermal insulation.

Target Industries & Applications
Tested and qualified for demanding industrial environments across Pakistan and international export markets:
Blended with cotton or 100% spun polyester for woven fabrics and knitting yarns.
Hollow conjugated siliconized fiber provides fluffy loft, high recovery, and softness.
Needle-punched non-woven felts for car headliners, trunk lining, road reinforcement, and insulation.
Thermal bonded wadding for winter jackets, comforters, and quilting.
Custom Formulation & OEM Inquiries
Require a specific tensile threshold, custom strap width/thickness, private label coil core printing, or exact flake intrinsic viscosity (IV)? Our Faisalabad technical team specializes in custom extrusion engineering.
