What Is Flannel Fabric? A Complete Guide for B2B Buyers
Flannel types, manufacturing process, and how to choose the right one for your custom blanket project.
Flannel is a soft, woven fabric known for its brushed surface that creates a fuzzy, warm texture. Originally made from wool, today‘s flannel is typically crafted from cotton, polyester, or a blend. For blanket manufacturing, 100% polyester double-brushed flannel is the most popular choice due to its durability, softness, and affordability.
The secret to flannel’s softness lies in the brushing process. After weaving, the fabric goes through metal brushes that lift the fibers, creating a soft, fluffy surface on one or both sides. Double-brushed flannel (brushed on both sides) is the softest and most commonly used for premium blankets.
For B2B blanket orders, 100% polyester double-brushed flannel is the industry standard. It’s lightweight, quick-drying, and holds color well — perfect for solid, printed, and glow-in-the-dark finishes.
Flannel is more than just a fabric — it’s the foundation of a great blanket. Whether you’re sourcing for a hotel chain, a promotional campaign, or your own brand, understanding flannel helps you make better decisions.
