Teijin Frontier, the fibres and products converting company of Teijin Group, has developed a new heat insulating structure for outdoor wear with two-layer functionality.
Outdoor wear warmth is determined by outer, middler and inner garments, which are added or excluded by the wearer regarding the level of activity 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, Teijin Frontier says it has not been possible to combine middler and inner functions because uneven surface caused by brushing yarn decreases sweat-absorption and quick-drying function.
In response, the firm has developed its new heat insulating structure, which combines sweat absorption and quick drying for innerwear and heat insulation for brushed-finish intermediate wear, or middler, worn between the inner and outer layers to retain heat.
The new structure offers a new type of bulky plush structure that does not brush. It is a double raschel knitted fabric cut in half, with its middle nodes made with Octa, Teijin Frontier’s hollow-core fibre. It also uses a distinct dyeing technology to maximise Octa’s crimping function and stabilise its high-quality plush structure. Comfort is enhanced with heat insulation and yarn tips on the skin side that evenly absorb sweat and dry quickly.
Teijin Frontier is positioning this new structure as a key material for outdoor wear in autumn and winter 2021 collections. Eventually, applications of the new structure will include outdoor, sports, casual and uniform applications, targeting annual sales of 1m metres in fiscal 2025.
