‘Soft and gentle’ spun yarn breakthrough for Teijin Frontier
The fibres division of Japanese group Teijin has launched a new polyester spun yarn.
Teijin Frontier said the new spun yarn, which it has called Octa SF, is lightweight and provides “a soft, gentle feel, fluffiness, moisture absorption and heat retention”. It said the new product will work particularly well for textiles used in sportswear and outerwear.
To create this new spun yarn, Teijin Frontier developed an ultra-fine staple fibre with a hollow, eight-fin modified cross-section, which the company has processed using special spinning and drawing technologies.
It said Octa SF overcomes the softness limitations of existing staple fibres made of filament yarn, and addresses “demands for new materials that combine high performance with desirable tactile feel”.
Now, Teijin Frontier intends to use the yarn to develop “special-structure fabrics”, primarily for outerwear and mid-layer garments. It will then work on material for baselayers and innerwear, for which it said the softer, more comfortable texture that Octa SF can offer will work well.
According to the company, these fabrics should be available for brands to use in their autumn-winter 2025-2026 collections.
