# Understanding Fabric Denier: The Difference Between 20D, 40D, and 50D Mesh Bases

For a technical sourcing manager, the "D" (Denier) number of a base mesh is more important than the sparkle of the sequins on top. At **Yunfan Textile**, we believe that a premium fabric starts with an engineered foundation. Here is a professional guide to understanding denier in sequin and embroidery fabrics.

## 1. 20D (The Ultra-Lightweight)
- **Characteristics**: Transparent, ethereal, and extremely soft.
- **Best For**: Delicate bridal veils and light lingerie overlays.
- **Limitation**: Not recommended for large or heavy sequins (5mm+), as the thread may tear the mesh under high tension.

## 2. 40D (The Industry Standard)
- **Characteristics**: The perfect balance between durability and drape.
- **Best For**: Standard 3mm sequin embroidery and high-street fashion gowns.
- **Technical Note**: Our 40D nylon mesh is double-heat-set to ensure dimensional stability during industrial sewing.

## 3. 50D (The Heavy-Duty Foundation)
- **Characteristics**: Rigid, high-tenacity, and extremely tear-resistant.
- **Best For**: 3D puff embroidery, beaded sequins, and commercial upholstery.
