A new self-adjusting fabric has a solid knitted fabric structure that changes shape in 3 directions in response to perspiration. Teijin Frontier has developed a highly comfortable knitted fabric that can change its structure three-dimensionally, thereby increasing breathability and eliminating the feeling of stuffiness. This fabric is made by specially textured, side-by-side (S/S) composite yarn made from two types of polymers, each with different hygroscopicity. The yarn’s structure also includes a coiled crimp.
In 2009, Teijin Frontier began offering a S/S composite yarn made with polymers of varying hygroscopicity and fabric in which the stitches open and close in response to perspiration. However, since the fabric’s stitches open wide in the presence of perspiration, causing clothing sizes to change significantly, it was necessary to limit stitch opening to a practical level for commercial applications.
Teijin Frontier Co., Ltd., Tokyo/Japan, will market its new self-adjusting fabric as a core product for year-round sports and outdoor use beginning in 2023. Wide ranging of applications will include casual and functional apparel and uniforms as well as various materials.
The features of the adaptive fabric are:
• highly adaptive breathability (about double that before sweating)
• minimal dimensional changes (5% or less both vertically and horizontally)
• good wind protection (ventilation rate of 50cc/cm2/sec or less)
• soft texture and attractive appearance
• combines with materials offering balanced functions or those for preventing sweat stains, sweat-induced chill or body odor
• adaptive breathability contributes to energy saving
Teijin Frontier expects to target sales of 250.000 m in 2024.
