At first glance, a baby diaper may seem like a simple product—but when you take a closer look, you’ll realize it’s a carefully engineered system made of multiple premium layers, each designed to keep babies dry, safe, and comfortable.
At Keiann, we’re committed to using only the highest-quality raw materials from trusted global suppliers. Here’s a breakdown of every key component inside our baby diapers—and why they matter.
Core Layer: Soft, Breathable, and Ultra-Absorbent
The core of a diaper is where absorption happens. At Keiann, we use:
Hot air fiber (pure cotton feel) for breathability and rapid fluid dispersion
SAP (Super Absorbent Polymer) from Sumitomo Chemical Japan, known for its fast absorption and long-lasting dryness
These materials work together to quickly lock in liquid and keep moisture away from the baby’s skin—even after multiple wettings.
Top Sheet & Acquisition Layer: Gentle on Baby’s Skin
The core of a diaper is where absorption happens. At Keiann, we use:
Hot air fiber (pure cotton feel) for breathability and rapid fluid dispersion
SAP (Super Absorbent Polymer) from Sumitomo Chemical Japan, known for its fast absorption and long-lasting dryness
These materials work together to quickly lock in liquid and keep moisture away from the baby’s skin—even after multiple wettings.
Elastic Parts: Flexible, Snug, and Leak-Proof
To ensure a secure yet gentle fit, we use:
Hyosung spandex from Korea for our elastic bands
High-stretch, skin-safe material that adapts to your baby’s movements
This gives the diaper flexibility without leaving red marks or gaps that could cause leakage.
Adhesive: Secure Fit Without Skin Irritation
Our diapers use Henkel medical-grade adhesive from Germany, which provides:
Strong and reliable fastening
Skin-friendly bonding that avoids irritation or allergic reactions
Excellent performance even after multiple refastenings
Because safety matters just as much as functionality.
