Fluff Pulp

1. What is Fluff Pulp for Diapers? (Definition & Function)

Fluff pulp is a cellulose fiber-based absorbent material used in the core layer of baby diapers. It works together with SAP (Super Absorbent Polymer) to rapidly absorb and distribute liquids, helping keep the diaper surface dry and comfortable.

In baby diaper production, fluff pulp provides:

• High liquid acquisition and distribution

• Bulk structure to support SAP absorption

• Fast absorption and low rewet

• Good softness and comfort

Material Types (Virgin Softwood / Mixed Wood / Treated / Untreated)

Suitable for Baby Diapers / Adult Incontinence / Sanitary Napkin / Pet Pads

2. Why Fluff Pulp Is Critical in Diaper Absorbent Cores

In modern hygiene products, fluff pulp is not just a filler material. It plays a key functional role by:

• Enhancing liquid diffusion before SAP absorption

• Preventing gel blocking of SAP

• Improving core resilience and shape stability

• Supporting thin-core and high-performance designs

High-quality fluff pulp helps manufacturers achieve better dryness, lower rewet, and improved user comfort.

4. Fluff Pulp vs SAP: How They Work Together

In absorbent cores, fluff pulp and SAP serve different but complementary roles:

• Fluff pulp

  • Absorbs and distributes liquid quickly

  • Maintains core structure

  • Prevents SAP clumping

• SAP (Super Absorbent Polymer)

  • Locks liquid permanently

  • Reduces leakage

  • Improves retention capacity

A well-balanced fluff pulp–SAP system delivers fast intake, high retention, and low rewet, which is essential for modern diaper performance.

6. How to Choose the Right Fluff Pulp

1. Fiber Length Selection

• Shorter fibers (≈2.2–2.6 mm): balanced absorption and distribution

• Longer fibers (≈2.7–3.2 mm): higher bulk and absorption capacity

2. Bulk Density Consideration

• Higher bulk improves absorption volume

• Lower bulk supports thinner core designs

5. Bleaching & Hygiene Standards

• Suitable for diaper and sanitary napkin hygiene requirements

• Consistent brightness and low ash content ensure safety and stability

Selecting the right fluff pulp improves both product performance and manufacturing efficiency.
