Teijin Frontier expands OCTAIR™ insulation fiber capacity at Matsuyama Plant
- Investment of several hundred million yen to install pre-processing, spinning and drawing equipment at Matsuyama Plant in Ehime Prefecture.
- Production using the new equipment is scheduled to begin in March 2027.
- OCTAIR™ has a hollow, eight-fin cross-section with radiating protrusions and offers thermal performance equivalent to down of the same weight.
- Initial output will be several hundred tons per year, planned to rise to approximately 1,000 tons annually by 2030; mass production will include PTT and recycled polyester variants.
Capacity expansion and schedule
Teijin Frontier will install new pre-processing, spinning and drawing equipment for OCTAIR™ polyester insulation fiber at its Matsuyama Plant in Ehime Prefecture, an investment of several hundred million yen. Production using the new equipment is scheduled to begin in March 2027.
Product structure and performance
OCTAIR™ features a hollow, eight-fin cross-section with radiating protrusions. The voided structure provides loft and light weight, with thermal insulation performance equivalent to that of down of the same weight, along with a supple, soft texture, dimensional stability and a smoother blowing-in process versus conventional polyester fiberfill.
Materials, volumes and market response
Developed in 2024 and test marketed, OCTAIR™ will be produced in several material variants, including products incorporating polytrimethylene terephthalate (PTT) fibers and recycled polyester. Initial production volume will start at several hundred tons per year, with a planned increase to approximately 1,000 tons annually by 2030 to supply growing demand for down alternatives.
