Modal is a type of rayon, a cellulose fiber made by spinning reconstituted cellulose, in this case often from beech trees. Modal is used alone or with other fibers (often cotton or spandex or lycra) in clothing.
MODAL IS A SEMISYNTHETIC TEXTILE AND NOT CERTIFIED ORGANIC.
Our Beechwood Modal fabric is buttery soft and composed of 96% Modal and 4% Lycra. It allows for extra stretch.
Modal is a wood pulp based cellulosic fiber, made out of pure wooden chips from the beech tree, technically as the European Schneider Zelkova tree. While viscose rayon can be obtained from the wood pulp from a number of different trees, modal uses only beech wood, thus it is essentially a variety of viscose rayon; a generic name for modified viscose rayon fiber that has high tenacity and high wet modulus.
Modal was first developed by Austria based Lenzing AG Company who trademarked the fabrics name, but now many manufacturers make their own versions. It was initially imported from Czech Republic, Slovakia, Hungary and Germany; but now for Indian market, it is catered to by Lenzing, Austria.
Modal fibers are defined in International Standard ISO 206: 999 (E) as high wet modulus, high breaking strength regenerated cellulose fibers produced by using particular viscose rayon, and regeneration bath compositions which allows greater molecular orientation during stretch and coagulation of the fibers. Modal as defined by the International Bureau for Standardization of Manmade Fibers (BISFA) is a distinct viscose rayon fiber genre, which has a higher wet modulus and satisfies a minimum value of tenacity in the wet stage at 5% elongation.
Shrinkage
Normal Acceptable shrinkage for all these fabrics is 3-5% international norm and we test each fabric in production to maintain this acceptable limit.
