Technical Performance Data
Our technical specifications are designed to meet the rigorous demands of the automotive and safety footwear industries. We provide full traceability and batch-testing reports for every roll of nonwoven base produced.
| Mechanical Property | Standard Test Method | Specification Range |
|---|---|---|
| Tensile Strength (MD) | ISO 9073-3 | ≥ 650 N / 5cm |
| Tensile Strength (CD) | ISO 9073-3 | ≥ 600 N / 5cm |
| Tear Strength (Trouser) | ISO 4674-1 | ≥ 110 N |
| Elongation at 50N | ASTM D5034 | < 5.5% |
| Mass per Unit Area | ISO 9073-1 | 200gsm - 1200gsm |
| Thickness Uniformity | Digital Micrometer | CV < 2.5% |
| Bursting Strength | ISO 13938-1 | ≥ 2.5 MPa |
| Shrinkage (100°C/30min) | Internal Thermal | ≤ 1.5% |
The consistency of our base is maintained through an automated cross-lapping and needle-frequency control system. This ensures that the fiber density is uniform across the entire width of the roll, preventing "weak spots" that could fail during high-tension industrial finishing.
Industrial Application Scenarios
The High Tensile Strength Nonwoven Base is the primary material for Safety & Performance Footwear. In the construction and military sectors, boots must withstand extreme abrasion and sharp impacts without the material splitting. Our base provides the internal strength required to pass international safety standards (such as EN ISO 20345) while remaining significantly lighter than traditional cowhide. In the Automotive Engineering field, this base is used for structural interior components, such as door panel inserts and seat bolsters, where the material must maintain its shape under the constant tension of the upholstery process and the weight of the passengers. The high dimensional stability ensures that the seams do not "grin" or pull apart over years of use.
Another critical scenario is in High-Performance Sports Equipment. From professional-grade soccer balls to boxing gloves, the material must endure thousands of high-velocity impacts. Our water-reduced base offers a superior "snap-back" or elastic recovery compared to solvent-reduced alternatives. Additionally, it is increasingly used in Industrial Filtration Belts. These belts operate in high-pressure environments where they must filter heavy slurries; our high tensile strength prevents the belt from lengthening or snapping, reducing machine downtime and maintenance costs. For luxury fashion, it provides the "fleshiness" and structural support for structured handbags that need to hold their shape without excessive internal stiffeners, allowing for more elegant and sustainable designs.
Strategic Core Advantages
- Maximum Tenacity Retention: By avoiding alkali and toluene, we preserve 100% of the polymer's original molecular strength, resulting in a base that is 20-30% stronger than traditional microfibers.
- Low Thermal Shrinkage: Our base remains stable during high-heat PU coating processes, ensuring that your finished rolls are flat, even, and free from "wavy" edges.
- Enhanced Resin Bonding: The pure water process leaves the fiber surface free from oils, allowing the polyurethane resin to bond more effectively to the fibers, which significantly improves peeling strength.
- Weight-to-Strength Ratio: Provides the strength of much heavier materials, allowing manufacturers to create lightweight products without compromising on safety or durability.
- Multi-Directional Stability: Engineered with a balanced MD/CD (Machine Direction / Cross Direction) ratio to prevent distortion during complex 3D molding or lasting.
- Oeko-Tex Standard 100 Compliance: The absence of chemical residues makes this base safe for skin-contact applications and medical-grade use.
Logistics & B2B Trade Terms
We supply our High Tensile Strength Nonwoven Base in roll form, with widths ranging from 137cm to 150cm as standard. Each roll is securely wrapped in moisture-proof polyethylene film and high-strength cardboard tubing to prevent any crushing during transit. As our facility is located near the Ningbo Port, we offer highly competitive FOB and CIF rates. We specialize in bulk fulfillment, with a monthly production capacity exceeding 500,000 meters, ensuring that we can support even the largest global supply chains.
Our payment terms are designed to facilitate long-term partnerships. We typically accept T/T (30% deposit, 70% against BL) or Irrevocable L/C at sight. For verified long-term partners, we can discuss open account (OA) terms or D/P arrangements. We provide a comprehensive technical documentation package with every shipment, including a Certificate of Analysis (COA) and physical test reports conducted in our ISO-certified laboratory. Shipping lead times for standard specifications are approximately 15-20 days. We also offer "Trial Roll" shipping via air freight for urgent R&D projects or initial quality validation.
- Q: How does this base compare to a woven fabric in terms of strength?
- A: While woven fabrics have high linear strength, our nonwoven base offers superior isotropic strength (strength in all directions) and better puncture resistance, making it ideal for 3D-formed products like shoes and car seats.
- Q: Can the tensile strength be customized for specific projects?
- A: Yes. We can adjust the needle-punching density and the island/sea ratio to meet specific N (Newton) requirements for your particular application.
- Q: Does the pure water process affect the shelf life?
- A: No. In fact, it improves shelf life because there are no residual solvents that could cause the material to yellow or degrade over time.
