The period underwear industry is evolving rapidly, and one of the biggest challenges has always been balancing high absorbency, leak protection, comfort, and thickness. Traditional absorbent fabrics often become bulky, heavy, and uncomfortable when designed for higher fluid retention.
That’s why Shanhao Undies has developed a new generation of absorbent fabric technology that delivers exceptional protection while remaining significantly thinner and more comfortable for everyday wear. According to the company’s latest fabric development data, the upgraded material achieves 25 times greater absorbency than traditional terry-based options while reducing thickness from 1.5 cm to 0.5 cm.
Shanhao’s Newly Developed Super Absorbent Fabric (SAF)
The latest innovation from Shanhao Undies introduces a Super Absorbent Fibre (SAF) structure specifically designed for:
- Period underwear
- Incontinence underwear
- Sanitary products
- Leak-proof apparel
Compared to the previous fabric version, the upgraded structure provides:
| Feature | Previous Fabric | New SAF Fabric |
|---|---|---|
| Thickness | 1.5 cm | 0.5 cm |
| Fluid Capacity | 100 ml | 100 ml |
| Absorbency Performance | 12x vs Terry | 25x vs Terry |
| Wash Resistance | 99 Cycles | 99 Cycles |
| Shrinkage | 8% | 8% |
| Super Absorbent Fibre | No | Yes |
| Tumble Dry Compatible | Yes | Yes |
The most impressive improvement is maintaining the same fluid capacity while reducing overall thickness by approximately 67%.
Why Thinner Matters
A thinner absorbent structure offers several benefits for both brands and consumers.
Better Comfort
Bulky absorbent layers can feel restrictive during daily activities. A thinner profile allows the underwear to feel closer to regular underwear while still providing protection.
Improved Fit
Slimmer absorbent technology helps garments sit naturally under:
- Leggings
- Jeans
- Athletic wear
- Dresses
- Uniforms
Greater Mobility
For active users, reduced thickness means less friction and better movement during exercise, work, and everyday activities.
Faster Drying
Thinner absorbent structures typically dry faster after washing, improving convenience and product usability.
Designed for Period and Incontinence Protection
The new absorbent fabric was developed specifically for products requiring reliable leak management.
Potential applications include:
- Period panties
- Heavy-flow menstrual underwear
- Postpartum underwear
- Incontinence underwear
- Reusable sanitary products
Shanhao specializes in manufacturing functional underwear solutions, including period underwear, incontinence underwear, and maternity products for international markets. The company reports certifications including ISO9001, GOTS, and BSCI.
The Future of High-Performance Absorbent Fabrics
Shanhao’s newly developed SAF absorbent fabric demonstrates how textile engineering can improve both comfort and performance by delivering:
- Higher absorbency efficiency
- Reduced thickness
- Long-lasting durability
- Reliable leak protection
- Better everyday comfort
