FUNCTIONAL SHEET
A functional sheet manufactured with staple fibers is provided. More particularly, a functional sheet is formed as a single layer or a composite layer by binding polyolefin staple fibers by needle punching, to enhance physical properties of the functional sheet so that the functional sheet may be used for various purposes, for example, for weed growth prevention, waterproofing, soundproofing, ground stabilization, civil engineering, construction and aging-friendly materials.
