Abstract:
The invention relates to a roll for use in a manufacture of a fibrous web, which comprises cellulosic fibers. The roll comprises a roll body with a cylindrical surface, and a roll cover, which is arranged to cover the cylindrical surface of the roll body. The cover has a functional layer, which has a polymer matrix and reinforcing material in the form of functional particles and/or functional fibers embedded in the polymer matrix. The functional particles and/or functional fibers has nanocellulose material. The invention relates also to the use of the roll.
