Teijin Frontier, the fibre product converting business of Teijin Group, has developed a new polyester material that it says achieves the look, texture, aesthetic appeal and comfort of hybrid silk wool.
The fabric is designed primarily for a wide range of medium-thickness apparel applications including jackets and bottoms, and will come under the firm’s Solotex brand.

Silk wool, a hybrid of silk and wool that came into use during the 1950s, is a high-function material noted for swelling, smoothness, softness, melange and dense colourings, a combination of properties not possible with synthetic materials until now, says Teijin.
To achieve the look and feel of natural silk wool, the company uses a multi-thickness structure to process straight polyester filament yarn, employing a proprietary higher-order thread-processing technology. The yarn is then blended with Solotex and finally undergoes post-dyeing processing.
The new material has colorings with dense spots that are close to those of natural materials. It is also said to eliminate the dry, rough touch of conventional wool-like materials and replicates the smoothness and high resiliency of wool.
In addition, it achieves easy-care properties including washability and crease resistance, and other functions such as water-repelling and antifouling properties, all of which cannot be associated with natural silk wool, according to Teijin.
