Definition
Modal fibers are defined as high wet modulus, high breaking strength re-generated cellulose fibers produced by using particular viscose rayon, and re-generation bath compositions which allows greater molecular orientation during stretch and coagulation of the fibers.
Modal is generally considered a more eco-friendly alternative to cotton because beech trees don’t require much water to grow and therefore the production process uses about 10-20 times less water.
Modal is a type of rayon fabric, but it is generally more durable than regular rayon and feels softer, like cotton. Modal is often blended with other fibers like cotton and spandex for added strength.
Limitations
- 100% Modal requires ironing and has a tendency to pile due to long fibers.
- Modal is more expensive than viscose rayon and cotton.
- Processing the beechwood into cellulose fiber is a man-made process that uses more energy than processing natural fibers.
