To select the right reflective fabric, you must prioritize the Coefficient of Retroreflection (Ra), the Backing Fabric durability (Polyester, TC, or Stretch), and Wash Cycles compliance. For professional-grade safety, ensure the material meets ISO 20471 or ANSI/ISEA 107 standards.
Quick Guide: Comparing Reflective Fabric Types
| Fabric Type | Best For | Industry Standard |
| Silver Fabric | High-Visibility Safety Vests | EN ISO 20471 / ANSI 107 |
| Color Reflective | Fashion, Sportswear, Bags | Oeko-Tex Standard 100 |
| Stretch Reflective | Yoga Wear, Cycling Gear | High-Elasticity Grade |
| Heat Transfer Film | Logos, Complex Designs | Industrial Wash Grade |
1. How Does Reflective Fabric Work?
Reflective fabric uses Retroreflective Technology, primarily through millions of high-refractive-index glass beads embedded in a cloth backing. When a light source (like car headlights) hits the fabric, these beads return the light directly back to the source, significantly increasing the wearer’s visibility in low-light conditions.
2. Which Backing Fabric Should You Choose?
- 100% Polyester: The go-to for lightweight, breathable safety vests.
- TC (Polyester-Cotton): A rugged, heavier blend (usually 65/35) designed for industrial workwear that requires high tear resistance.
- Spandex/Stretch: Essential for performance wear where the fabric must expand without cracking the reflective coating.
3. Why Reflectivity (Ra) and Wash Cycles Matter
- Reflectivity: High-grade silver fabric typically offers Ra > 420 cd/(lx·m²) .
- Wash Durability: Standard fabrics last 25 cycles, while 산업용 세척 versions can withstand 50+ cycles at 60℃
Frequently Asked Questions (FAQ )
Q: Can I customize the width of reflective fabric rolls?
A: Yes. Standard rolls are typically 100cm to 140cm wide, but they can be precision-slit into tapes ranging from 1cm to 100cm to fit specific design needs.
Q: Is rainbow reflective fabric safe for professional use?
A: Rainbow or “iridescent” reflective fabric is excellent for fashion and aesthetics, but it usually does not meet the strict （Ra） requirements for Class 2 or Class 3 safety certifications.
Q: What is the difference between Reflective Fabric and Heat Transfer Film?
A: Reflective fabric is a complete cloth material, while Heat Transfer Film (HTF) is a vinyl-like layer that is heat-pressed onto an existing garment. HTF is better for logos and intricate patterns.
