The Interaction Between Fiber Length and Core Integrity
Core integrity depends on the balance between the two fiber types:
-
High long-fiber content (60–80% softwood) : Produces a strong, resilient core that resists tearing and clumping. However, the core may be less uniform, with larger voids between fibers, leading to less efficient liquid distribution.
-
High short-fiber content (60–80% hardwood) : Produces a dense, uniform core with excellent liquid distribution. However, it may lack structural strength and may be prone to tearing or collapsing under pressure.
-
Balanced blend (50:50 to 70:30 softwood:hardwood) : Achieves a compromise between strength and uniformity, providing good core integrity without sacrificing absorption performance.
Practical Effects on Diaper Performance
-
Tear resistance: Long fibers provide excellent tear resistance, preventing the core from breaking apart during manufacturing, packaging, or use.
-
Clump resistance: Long fibers prevent gel particles from agglomerating into hard lumps. A core dominated by short fibers may form clumps that create uncomfortable pressure points.
-
Uniform absorption: Short fibers improve liquid distribution, reducing the risk of localized saturation and gel blocking.
Why This Matters for Procurement
For buyers, understanding the pulp fiber blend in a diaper's core is a key factor in evaluating product quality. A core that is too heavily dependent on long fibers may feel lumpy or uneven; a core that relies too heavily on short fibers may lack strength and tear easily. The optimal blend depends on the target market and price positioning, but a balanced blend is generally a hallmark of a well-engineered product.
