R&D Center – Science Behind Soft Care
Innovating Absorbent Hygiene & Bioactive Skincare
Our R&D Center is dedicated to next-generation absorbent hygiene (sanitary pads, adult/baby diapers) and functional sheet masks, with a special focus on fully biodegradable structures and chitosan-based antibacterial systems.
At the heart of our innovation lies the Fortune Cat™ technology platform – a proprietary framework that combines biomaterial science, intelligent absorbency design, and eco-engineering.
Fortune Cat™ Technology Platform – Overview

Fortune Cat™ is a registered technology trademark owned by our R&D center. All modules are scalable from pilot to commercial batches.
1. Core Research Areas
1.1 Chitosan for Hygiene & Skincare
We have 12 years of formulation experience with chitosan of different molecular weights and degrees of deacetylation (DD).
| Application | Chitosan Form | Key Benefit |
|---|---|---|
| Sanitary pad top sheet | Chitosan-grafted PP/PE nonwoven | Antibacterial, odor control, pH regulation |
| Adult diaper liner | Chitosan-coated spunlace | Rash prevention, moisture management |
| Chitosan sheet mask | Chitosan fiber (wet-laid or needle-punched) | Heavy metal binding, antibacterial, moisturizing |
| Biodegradable core | Chitosan-fluff composite | Partial superabsorbent替代, reduces SAP use |
In-house capabilities:
-
DD measurement (colloidal titration)
-
Molecular weight determination (viscometry/GPC)
-
Antibacterial efficacy (ASTM E2149, JIS L1902, AATCC 100)
-
Cytotoxicity (ISO 10993-5) – for medical-grade products
1.2 Fully Biodegradable Absorbent Products
Our Fortune Cat™ PureBio program aims to replace petroleum-based components:
| Component | Traditional Material | Fortune Cat™ PureBio Alternative | Biodegradation Standard |
|---|---|---|---|
| Back sheet | PE film | PLA or PBAT film (compostable) | EN 13432 / ASTM D6400 |
| Top sheet | PP nonwoven | PLA nonwoven or bamboo viscose | OK Biodegradable SOIL |
| Core wrap | Tissue + SAP | Bamboo tissue + bio-SAP (partial) | >90% in 180 days |
| Adhesive | Hot-melt (synthetic) | Bio-based hot-melt (Renewable content ≥70%) | Self-declared + ecotoxicity pass |
| Packaging | PE/PP film | Compostable film (NatureFlex or similar) | EN 13432 home compostable |
We provide batch-specific biodegradation certificates from DIN CERTCO / TÜV Austria for Fortune Cat™ PureBio products.
1.3 High-Performance Absorbent Core Engineering

|---|---|---|
| Absorbency (synthetic menstrual fluid) | 30–80mL (by pad size) | 50–120mL |
| Rewet (surface dryness) | ≤1.2g | ≤0.8g |
| Fluid intake speed (first gush) | ≤8 seconds | ≤5 seconds |
| Core structure | Fluff + SAP (mixed) | Airlaid + SAP (layered) |
All data generated on in-house test rigs calibrated to ISO 11948-1 and WSP (Worldwide Strategic Partners) standards.
2. R&D Facilities & Equipment
