Teijin Frontier Develops Next-generation
Heat Insulating Structure
Tokyo, Japan, August 3, 2020 --- Teijin Frontier Co., Ltd., the Teijin Group's fibers andproducts converting company, announced today its new heat insulating structure which
combines sweat absorption and quick drying for innerwear and heat insulation forbrushed-finish intermediate wear, or middler, worn between the inner and outer layers toretain heat. Teijin Frontier is positioning this new structure as a key material for outdoor
wear in fall and winter 2021 collections. Eventually, applications of the new structure will
include outdoor, sports, casual and uniform applications, targeting annual sales of one
million meters in fiscal 2025.

The new structure offers a new type of bulky plush structure that does not brush. It is adouble raschel knitted fabric cut in half with high precision. Its middle nodes are made with
Octa, Teijin Frontier’s highly modified hollow-core fiber with eight projecting fins aligned
in a radial pattern. It also uses a distinct dyeing technology to maximize Octa’s crimping
function and stabilize its high-quality plush structure. Unprecedented comfort is enhancedwith heat insulation (lightweight bulkiness and warmth) and yarn tips on the skin side that
evenly absorb sweat and dry quickly.

Outdoor wear warmth is determined by outer, middler and inner garments which areadded or excluded by the wearer in accordance with expectations regarding level ofactivity and usage environment. However, the expanding everyday use of outdoor wear
has raised the demand for single layers offering two-layer functionality, in particular, a
compact layer with both middler and inner functions. Whereas brushing yarn is mainly
used to achieve heat insulation in middler, the inner layer typically requires
sweat-absorption and quick-drying functions. Until now, however, it has not beenpossible to combine middler and inner functions because uneven surface caused bybrushing yarn decreases sweat-absorption and quick-drying function.
