Toray Chemical has succeeded in developing micro-scale hollow fibers that can replace fillers such as goose feather for winter jackets. Toray is a South Korea-based textiles maker. The micro-scale hollow fiber is made by combining two types of polyester polymers and has a spiral shaped fiber structure, or three-dimensional crimp, making it possible to enclose more air to retain heat better.
The company has developed a new product by maximising the advantages of natural fabrics and fixing the weakness through high-level textile processing technology.
The special fiber is soft and light in weight. It can be widely used to make fillers for various products from winter outdoor sports jackets to beddings such as comforters and pillows. Also, the micro-scale hollow fiber has a tendency to restore its original shape that increases its ability to maintain heat.
The fiber is expected to replace the goose and duck feathers commonly used as fillers for beddings and winter jackets. This is in deference to growing voices on protecting animals. Also it is considered eco-friendly as it is possible to recycle the products made of the special fiber back as raw materials. Fabrics with micro-scale hollow fiber withstand wear and tear better and entangle less when machine-washed.
