Absorbent Core Technologies

The Heart of Every Sanitary Pad & Diaper

The absorbent core is the most critical component of any hygiene product — determining absorption speed, leak prevention, rewet performance, and overall user comfort. At Fortune Cat™ Fiber Manufacturing LLP, we engineer and manufacture a full spectrum of absorbent cores for sanitary pads, baby diapers, adult incontinence products, and nursing pads.

Our proprietary technologies — Fortune Cat™ Shield (chitosan antibacterial integration), Fortune Cat™ PureBio (fully biodegradable systems), and Fortune Cat™ DryWave (fluid management) — can be incorporated into any core type to meet your brand’s performance and sustainability goals.

Part 1: Core Types — Complete Technical Specifications

Based on current industry standards and our manufacturing capabilities, absorbent cores fall into two primary categories, with several advanced variants.

---

1. Fluff Pulp Core (Traditional / Wood Pulp Core)

Structure & Composition

A homogeneous mixture of fluff pulp (70–80%) and superabsorbent polymer (SAP, 20–30%) , without layered separation or adhesive bonding. The fluff pulp provides rapid liquid wicking and distribution, while SAP locks fluid away from the skin.

Technical Parameters

Parameter	Typical Value
SAP Content	20–30%
Fluff Pulp Content	70–80%
Basis Weight	150–400 g/m²
Core Thickness (dry)	3–8 mm
Absorbency Capacity	100–400 mL (depending on size)
Retention Under Load	10–18 g/g
Biodegradability	Partial (pulp degrades; SAP does not)

Advantages

• Excellent fluid wicking and distribution
• Fast initial absorption
• Lower manufacturing cost
• Proven, mature technology

Disadvantages

• Absorbs water and expands unevenly — prone to lumping, clumping, and sagging during use
• Thicker and bulkier than composite alternatives
• Non-biodegradable SAP component persists in landfills for >500 years

Best Applications

• Economy-grade sanitary pads
• Adult incontinence briefs (high capacity requirement)
• Healthcare underpads

---

2. Composite Core (Full SAP Core / Airlaid Core)

Structure & Composition

A layered structure composed of nonwoven fabric + SAP + tissue paper, bonded with hot melt adhesive. Each layer is precisely engineered for fluid acquisition, distribution, and storage.

Technical Parameters

Parameter	Typical Value
SAP Content	60–80%
Nonwoven/Tissue Content	20–40%
Basis Weight	100–350 g/m²
Core Thickness (dry)	0.8–2.5 mm
Absorbency Capacity	150–500 mL
Retention Under Load	18–28 g/g
Biodegradability	Low (SAP non-biodegradable)

Advantages

• Ultra-thin — enables sleek product design
• No clumping or sagging — retains shape when wet
• High SAP concentration provides superior fluid retention
• Excellent rewet performance

Disadvantages

• Higher manufacturing complexity and cost
• Hot melt adhesives may introduce VOCs and formaldehyde
• Slower initial absorption versus fluff pulp cores

Best Applications

• Premium ultra-thin sanitary pads
• Premium baby diapers (overnight, active fit)
• Adult pull-up pants

---

3. Hybrid Core (Semi-Core / Combination Core)

Structure & Composition

An engineered combination: upper layer of composite core (for thinness and stability) + lower layer of fluff pulp/SAP mixture (for rapid wicking and bulk absorption). This design represents a compromise between traditional and composite technologies.

Advantages

• Balances cost and performance
• Improved fluid distribution versus pure composite
• Reduced adhesive content versus full composite

Disadvantages

• Still contains non-biodegradable SAP
• Moderate clumping risk

Best Applications

• Mid-tier sanitary pads
• Mid-tier baby diapers
• Products requiring balance of thinness and capacity

---

4. Needle-Punched Non-Adhesive Core (Gel-Free)

Structure & Composition

A three-layer structure: top nonwoven + intermediate layer (cotton fibers + SAP granules) + bottom nonwoven, bonded via needle-punching technology without any hot melt adhesive or chemical binders.

Advantages

• Zero adhesive — no formaldehyde, no VOCs, no toxic residues
• Environmentally friendlier manufacturing
• Good structural integrity without chemical bonding

Disadvantages

• Lower production speed than conventional methods
• Limited availability from manufacturers

Best Applications

• Organic/natural hygiene brands
• Medical-grade products requiring zero chemical additives

---

5. Biopolymer Core (Biodegradable / Plant-Based)

Structure & Composition

Uses natural biopolymers (cellulose, chitosan, sodium alginate, CMC, starch derivatives) to replace or significantly reduce petroleum-based SAP. Aligns with Fortune Cat™ PureBio program.

Performance Comparison

Core Type	Absorbency (g/g)	Biodegradation Time	Key Reference
Conventional SAP Core	35–45	>500 years	Internal testing
Cross-linked Cellulose-Chitosan Hydrogel	85 (in saline)	6–12 months	Internal testing
Carboxymethylated Cassava Starch	380+ (water)	48-hour solvent hold	Internal testing
Sodium Alginate + CMC Blend	Comparable to SAP	Biodegradable	Internal testing
Nanocellulose Hydrogel	~24	~40% in 28 days	Internal testing

Advantages

• Truly biodegradable (compostable under industrial conditions)
• Non-toxic, skin-friendly
• Made from renewable resources (plant waste, agricultural byproducts)
• Low carbon footprint potential

Current Limitations

• Slightly lower absorbency under load than premium synthetic SAP
• Higher material cost at present scale
• Industrial composting infrastructure still developing

Best Applications

• Eco-friendly / sustainable brand lines
• Products targeting EU markets (EN 13432 compliance)
• Premium natural hygiene ranges

---

6. Chitosan-Enhanced Core — Fortune Cat™ Shield

Structure & Composition

A patented modification applicable to ANY core type above — fluff pulp, composite, biopolymer, or needle-punched. Chitosan (derived from shellfish or fungal sources) is incorporated into the core via:

• Chitosan-grafted viscose fibers blended into the core matrix
• Chitosan hydrogel coating on SAP granules
• Chitosan nonwoven layers within core structure

Chitosan Properties (Data Sources)

Property	Value	Source
Chitosan fiber specification	1.11–6.66 dtex × 38–102 mm	Internal testing
Equilibrium moisture regain	12–16%	Internal testing
Water retention value	~130%	Internal testing
Zone of inhibition (E. coli)	17 ± 1.2 mm	Internal testing
Zone of inhibition (S. aureus)	10 ± 1.1 mm	Internal testing
Cross-linked cellulose-chitosan hydrogel retention	85 g/g in saline	Internal testing

Functional Benefits

Benefit	Description
Antibacterial	>90% reduction against E. coli, S. aureus, Candida
Moisture management	Exceptional wicking and breathability
Odor control	Natural amine groups bind odor-causing molecules
Skin compatibility	Biocompatible, non-toxic, reduces rash risk

Applications

• Fortune Cat™ Shield sanitary pads — odor control + infection prevention
• Fortune Cat™ Shield baby diapers — rash reduction
• Fortune Cat™ Shield adult incontinence — skin health protection
• Chitosan facial masks — antibacterial + moisturizing

Declaration: All Fortune Cat™ products can be added with chitosan fiber antibacterial function upon request.
