STAPLE FIBER NONWOVEN GEOTEXTILE
Staple Fiber Needle-Punched Nonwoven Geotextile for Separation, Filtration and Drainage
A PP- or PET-staple-fiber needle-punched nonwoven geotextile for separation, filtration, drainage, reinforcement and protection in civil and environmental engineering applications.
PRODUCT OVERVIEW
Nonwoven Geotextile for Filtration, Separation and Protection
The listed raw-material basis is PP or PET staple fiber, formed into a needle-punched nonwoven geotextile. Its functions include separation, filtration, drainage, reinforcement and protection.
Polymer material requirement, performance class, roll dimensions and acceptance criteria should be confirmed for the specific project and order.
MATERIAL & NONWOVEN STRUCTURE
Staple-Fiber Material Formed Through Needle-Punched Construction
The product is presented as a needle-punched nonwoven material rather than a range of separate sub-models. Selection should focus on the required material basis, areal mass, performance class and engineering function.
Staple-fiber material
PP or PET staple fiber is identified as the main raw-material basis.
Needle-punched nonwoven
The material is formed as a nonwoven geotextile through needle-punched construction.
Filtration & permeability
Opening size and vertical permeability are relevant to filtration and drainage review.
Separation & protection
Mechanical properties support evaluation for separation, reinforcement and protection functions.
APPLICATIONS
Engineering Contexts for Geotextile Selection
Application conditions, required function and project specifications should be considered together when defining the geotextile requirement.
Water Conservancy & Hydropower
Geotextile functions can be considered in water-conservancy and hydropower engineering systems.
Roads, Railways & Tunnels
Separation, filtration, drainage, reinforcement and protection requirements may govern selection.
Ports, Airports & Coastal Engineering
Product review should reflect the site conditions and specified engineering function.
Environmental Protection Works
Material and performance requirements should be aligned with the environmental project specification.
Filtration, Separation & Drainage
Opening size, permeability and mechanical properties are relevant selection inputs.
Reinforcement & Protection
Areal mass, strength class, bursting and tearing properties should be reviewed against project needs.

SELECTION CONSIDERATIONS
Information to Define Before Product Selection and Procurement
A clear inquiry should identify the functional, dimensional and performance requirements that govern product review and acceptance.
Polymer material requirement
State the required polymer basis rather than assuming PP and PET are interchangeable for every specification.
Areal mass
Provide the stated areal mass and any project tolerance or acceptance requirement.
Strength class
Identify the nominal longitudinal and transverse breaking-strength class.
Roll dimensions
Confirm required roll width and length for procurement and handling planning.
Elongation
Define the applicable elongation requirement within the project specification.
Bursting & tearing strength
Identify the mechanical requirements associated with the selected class.
Equivalent opening size
Confirm the required opening-size criterion for the intended filtration function.
Vertical permeability
State the permeability requirement governing filtration or drainage review.
Project specification
Provide the governing specification and any referenced performance class.
Acceptance requirements
Define required inspection items, records and contractual acceptance criteria.
MANUFACTURING & QUALITY
Align Production and Quality Review with the Confirmed Requirement
Material requirements, dimensional requirements, performance criteria and the required inspection/documentation package should be confirmed before production and supply.
- Polymer material and stated areal mass
- Roll width, length and dimensional requirements
- Applicable performance class and common indicators
- Required inspection records and procurement documents
