A 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 has been introduced by the fiber-product converting company Teijin Frontier Co., Ltd., Tokyo/Japan.
Applications of the new structure will include outdoor, sports, casual and uniform applications, as it offers a new type of bulky plush structure that does not brush. It is a double 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 8 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. Very good comfort is enhanced with heat insulation (lightweight bulkiness and warmth) and yarn tips on the skin side that evenly absorb sweat and dry quickly.
