Strong Nonwoven Fabrics for Use in Silt Control Systems

摘要

Strong nonwoven fabrics can be used as a sheet in a silt screen fence or other temporary silt screen barrier. The fabrics can be without reinforcements. Enhanced features of these strong nonwoven fabrics can enable them to be used as a sheet in a silt screen fence or other temporary silt screen barrier without adding additional processing steps. A strong nonwoven fabric without internal or external reinforcement that does not tear easily and has excellent light stability can be used.
