主纤维针打了Nonwoven Geotextile

Staple Fibers Needle Punched Nonwoven GeotextileStaple fibers needle punched geotextile is made of staple fibers on carding cross-laying equipment and needle punched equipment.Feature:It owns the advantages of acid and alkali resistance, erosion resistance, aging resistance, large strength, stable size, good filter ability etc.Application:Geotextile Function in1. Building ConstructionRoofing system & sub- structure:• Protection and a separation layer for thermal insulation• Protection layer for waterproofing materials.• Roofing and Re-roofing (inverted roofing system)• Sub structure, Foundation, underground structure2. Civil engineeringFiltration, Separation and Protection:• Drainage system, Waste Containment, Canals, Rivers, Sea work• Soil Stabilization / Erosion control.• Load Distribution, Roads, Railways, Airports• Paving & Repaving.Filtration: Filtration is one of the functions most widely performed by Geotextiles. The filtiration function has two concurrent objectives; to retain the particles of the filtered soil, while permitting water to pass through the plane of the geotextile from the filtered soil. These two parallel roles are the key to filtration design.Separation: Separation refers to the ability of geotextiles to prevent the mixing of two materials, such as soft subgrade with clean base aggregates.Reinforcement: Soil movement is reduced by the confinement and reinforcing action of the geotextiles, which function by absorbing part of the stress that normally would cause shear failure.Drainage: The lengthwise permeability of the geotextile allows it to perform as a drain. The amount of drainage is proportional to the thickness of the fabric.Staple Fibers Needle Punched Geotextile Property Index Index Spec.
