A nonwoven is a sheet of fibres, continuous filaments, or chopped yarns of any nature or origin, that have been formed into a web by any means, and bonded together by any means, with the exception of weaving or knitting. Felts obtained by wet milling are not nonwovens.
Spunbond Polypropylene is a nonwoven fabric composed of thermally bonded, continuous polypropylene filaments. The structure gives it good filtration properties and tensile strength even in diagonal direction. In addition, it is made of 100% polypropylene, which makes it resistant to moisture and chemical attack. It is a unique composite media that combines polymer technology with nonwoven manufacturing expertise. The polypropylene based material is an exceptionally strong yet light material with excellent drainage and permeability properties. It is manufactured by a unique integrated process in which continuous filaments of polypropylene are spun and then immediately formed into a multi directional arranged web that is heatbonded at filament crossover points. Spunbond Polypropylene filtration media are harmless to your health and do not pollute the environment, neither in production nor in use. Because Spunbond Polypropylene is made up of 100% polypropylene, with no binders or fillers, they can be easily recycled making a greener environment. So spunbond polypropylene is Eco-friendly.
In addition to the standard polypropylene spunbond, specific performance enhancing properties and characteristics can be provided including :
