Already regarded as a “wonder fabric” for its lightness, softness, warmth even when wet, and other qualities, scientists from China say they have been able to improve on the natural properties of wool. They say their discovery could give wool a “brain,” placing it among other “smart” fabrics that shake off wrinkles, shrinkage and “breathe” to release perspiration.
