III. Physical and Mechanical Properties of 7031 Nonwoven Fabric
1. Packaging: Each roll of nonwoven fabric is wrapped in a plastic film, then an outer waterproof woven bag. The ends of the core are sealed with corresponding plastic cores. The inner tube is a 1.8cm thick high-pressure paper tube.
2. Marking: The outer packaging bag should be marked with the manufacturer, product name, model, specifications, batch number, net weight, production date, etc.
3. Storage: 7031 nonwoven fabric should be stored in a cool, dry, clean, and well-ventilated warehouse below 40℃. It should not be near fire sources or heating, and should not be exposed to direct sunlight. The shelf life is one year.
IV. Scope of application:
Widely used in composite materials (DMD, DM, DMDM), mica tape reinforcing materials, electrical laminates, insulating varnish cloth base fabric, and end wrapping of electrical appliances, transformers, and motor coils. It is also suitable for small and flexible cables, household electrical cables, communication optical cables, and can replace various types of paper insulation materials.
Polyester Fiber Nonwoven Fabric Material is a versatile, high-performance fabric widely used in industrial, medical, automotive, filtration, and consumer applications. Unlike woven or knitted textiles, nonwoven fabrics are made by directly bonding fibers through mechanical, thermal, or chemical processes, resulting in a lightweight, durable, and uniform material.
Understanding Polyester Fiber Nonwoven Fabric Material Price is essential for buyers, engineers, and purchasing managers who need to make cost-effective decisions while ensuring high-quality performance. Prices vary based on fabric weight, thickness, fiber type, production process, flame-retardant treatment, and supplier reliability.
This guide covers product overview, technical specifications, applications, usage instructions, and common questions, with insights into factors affecting pricing and cost-efficiency.
Polyester Fiber Nonwoven Fabric is primarily made from polyethylene terephthalate (PET) fibers, offering excellent mechanical strength, dimensional stability, thermal resistance, and chemical resistance.
Key characteristics include:
Lightweight and flexible, yet strong and durable
High tensile and tear strength
Thermal resistance for continuous use up to 150°C
Flame-retardant options available for safety-critical applications
Low moisture absorption for industrial and electrical use
Cost-effective and recyclable
The price of polyester fiber nonwoven fabric is influenced by material quality, production method, weight, thickness, and any additional treatments such as flame-retardancy or anti-static coating. Bulk orders or long-term contracts with manufacturers often reduce unit cost, while specialty nonwovens with advanced performance features may be priced higher.
Typical specifications of polyester fiber nonwoven fabric affecting performance and price include:
Material Composition: 100% PET fibers or blends with polypropylene or other synthetic fibers
Manufacturing Process: Spunbond, needle-punched, hydroentangled, or thermal bonded
Fabric Weight: 20 g/m² – 400 g/m²; heavier fabrics generally cost more
Thickness: 0.1 mm – 5 mm, adjustable based on application
Fiber Orientation: Random or directional for enhanced mechanical strength
Tensile Strength: Customizable, higher strength may increase price
Porosity: Adjustable for filtration or insulation purposes
Thermal Resistance: Continuous operation up to 150°C, price may vary with high-temperature-resistant variants
Flame Retardancy: Optional UL or EN compliant treatments may affect cost
Color: White, gray, or customizable; dyed fabrics may incur additional charges
Eco Compliance: RoHS and REACH compliant, recyclable material
Manufacturers often provide detailed datasheets specifying the weight, thickness, density, and treatment type, which are crucial for pricing transparency.
Several factors determine the final cost of polyester fiber nonwoven fabrics:
Fabric Weight and Thickness: Heavier and thicker fabrics use more raw materials, increasing the price per square meter or roll.
Fiber Quality: Premium PET fibers with uniform diameter and high tensile strength command higher prices.
Production Method: Spunbond and needle-punched processes differ in cost; hydroentangled fabrics may be more expensive due to additional processing.
Special Treatments: Flame retardant, anti-static, hydrophobic, or chemical-resistant coatings add to production costs.
Order Quantity: Bulk orders reduce per-unit cost, while small quantities or custom sizes increase it.
Supplier Reputation and Location: Established manufacturers with quality certifications may charge premium prices.
Customization: Color, fiber blend, layering, or lamination services influence cost.
Market Demand: Global polyester prices, raw material availability, and shipping costs affect market prices.
Understanding these factors helps buyers select a cost-effective yet high-quality polyester fiber nonwoven fabric for their projects.
