About Soybean Fiber

Soybean fiber is the only renewable botanic fiber made of natural soybean cake. It has the natural softness of cashmere and the hypoallergenic property of silk. It consists of 16 amino acids that are healthy for human skin. Due to its high protein composition, it is very skin-friendly and will not irritate the skin easily. Soybean fiber is a new green fiber that can be reproduced repeatedly with natural soybeans and eco-friendly production processes.

What Makes Soybean Fiber a Great Duvet Filling?

As protein fiber, soybean fiber is naturally hypoallergenic with great breathability to wick away excess moisture quickly. Its texture allows it to perform great insulation just like natural wool, adding microfiber to the filling not only makes the duvet lofty in texture but it also improves the duvet’s capability to prevent cold air from entering.

Soft Texture: Soybean fiber has great elasticity, allowing the comforter to always remain lofty.

Warm: Lofty texture allows soybean fiber to stay insulated and warm.

Moisture Wicking: Soybean fiber consists of numerous small holes to wick away excessive moisture.

Best Filling Ratio

20% v. 80% is just the right filling ratio for a soybean fiber duvet While soybean fiber provides warmth and breathability, polyester gives the comforter extra softness for the best comfort.

Useful Designs  

Extended Sides: Allow fillings to breathe in the fresh air every time you make your bed.

Corner Loops: That can be tied up with a duvet cover to make sure the comforter stays in place.

Sewn-Through Construction: To provide consistent warmth even after washing.
