PROCESS FOR IMPROVING THE CHEMICAL AND/OR PHYSICAL PROPERTIES OF HOLLOW-STRUCTURE NATURAL FIBERS

摘要

For improving the chemical and/or the physical properties of hollow-structure natural fibers, such as kapok fibers, the fibers are subjected to a process, which determines the internal coating and/or filling thereof, at least partly, with a substance capable of improving the chemical and/or the physical properties of the fibers.
