METHOD AND DEVICE FOR PRODUCING A NONWOVEN GEOTEXTILE, AND GEOTEXTILE THUS PRODUCED

摘要

A nonwoven geotextile includes: crushed plant stems (305) more than five millimeters in diameter; plant stem fragments (310); and plant fibers (315) partially attached to the crushed stems, wherein the plant stems and the plant stem fragments are interwoven by element of mechanical connections produced by spraying water. In preferred embodiments, the plants include hemp. The device for producing such a nonwoven geotextile includes: elements for arranging plants into a mat including crushed plant stems more than five millimeters in diameter, plant stem fragments and plant fibers partially attached to the crushed stems; and elements for spraying water onto the mat so as to form mechanical connections between the crushed plant stems, the plant stem fragments and the plant fibers of the mat.
