Non-woven Fabric Slitting Circular Blades: Applications and Materials
Non-woven fabric slitting circular blades are critical tools in non-woven processing, installed on slitting machines to precisely cut non-woven materials into predetermined sizes using the strong shearing force generated by high-speed rotation. They ensure smooth, burr-free edges, directly impacting product quality and production efficiency.
Diverse and Specialized Applications
Medical Field
The blades’ precision cutting ensures aseptic slitting of medical dressings, guaranteeing the cleanliness and safety of materials in contact with wounds.
In mask production, they accurately cut multi-layered protective materials to maintain the integrity of respiratory protection structures, meeting medical-grade hygiene standards.
Consumer Goods
For wet wipes and facial tissues, the blades achieve micron-level precision in cutting dimensions, ensuring smooth, burr-free edges and enhancing user tactile experience.
High-speed continuous cutting meets the efficiency demands of mass-producing daily necessities.
Industrial Manufacturing
For filter materials, custom blade angles protect fiber structures from damage, preserving the materials’ breathability and interception performance.
In geotextile processing, their sharpness and wear resistance ensure regular cutting of large-scale materials, directly influencing the anti-seepage and reinforcement effects in water conservancy and road engineering projects.
Material Advantages
High-Speed Steel
Features excellent red hardness, maintaining cutting performance at high temperatures, along with superior wear resistance and toughness.
Heat treatment can increase hardness to 63–66HRC and fatigue strength to 800–1000MPa.
Ideal for high-precision cutting scenarios (e.g., medical masks, surgical gowns), ensuring smooth, burr-free edges.
Carbide (Tungsten Carbide)
Composed primarily of tungsten carbide, with hardness reaching 89–93HRA (far exceeding ordinary steel), offering extreme wear and corrosion resistance.
Lasts 3–5 times longer than high-speed steel blades when cutting non-woven composites with hard materials (e.g., glass fiber, carbon fiber).
Drawbacks: Higher density (~14.8g/cm³), lower toughness (impact toughness: 3–8J/cm²), and 3–5 times higher manufacturing cost than high-speed steel.
Used in high-efficiency industries like aerospace and automotive manufacturing.
Alloy Tool Steel
A mainstream choice for its balanced performance and cost-effectiveness.
Example 1: 9CrSi steel (with Cr and Si) achieves 62–65HRC hardness after quenching, suitable for ordinary non-woven slitting.
Example 2: Cr12MoV steel (with Mo and V) maintains 58–62HRC hardness while enhancing toughness (impact toughness: 15–25J/cm²), meeting mid-to-high-end non-woven cutting needs at lower costs. Widely used in household paper and packaging material production.
