Generally, ironing flannel fleece is not recommended, particularly if the material contains synthetic fibers like polyester, as high heat can cause it to melt, flatten the nap, or become damaged.
Understanding Flannel Fleece
While the term "flannel fleece" might sound like a combination of two fabrics, it often refers to a type of synthetic fleece fabric that is napped on both sides, giving it a soft, plush feel similar to flannel. Unlike traditional flannel, which is a woven fabric (often cotton or wool) with a brushed surface, fleece is typically knitted polyester.
Why Ironing is Risky for Fleece
Synthetic fibers, common in fleece materials, have low melting points. Applying the direct heat of an iron can easily:
- Melt or scorch the fibers.
- Flatten the soft nap, ruining the texture and feel.
- Create shiny spots or stiff areas.
What About Ironing Traditional Flannel?
It's important to distinguish between flannel fleece and traditional flannel. The provided reference states the following about traditional flannel:
You can tumble dry flannel but on low heat. It's best to let your flannel clothes hang up to air dry. This helps preserve the fabric and prevents wrinkling, so you don't need to iron flannel.
This suggests that even for traditional flannel, air drying is preferred to prevent wrinkles and avoid the need for ironing altogether.
Alternatives for Removing Wrinkles
Since ironing is risky for flannel fleece, consider these alternatives for wrinkle removal:
- Air Drying: As recommended for traditional flannel in the reference, air drying is excellent for preventing wrinkles in the first place. Hang the item while slightly damp.
- Steaming: Using a garment steamer is a much safer option than ironing. The steam relaxes the fibers without direct, high heat.
- Using a Wrinkle Release Spray: These sprays can help relax wrinkles when the fabric is hung.
- Machine Drying on Low/No Heat: If you must use a dryer, use the lowest possible heat setting or an air-only cycle. Remove the item promptly to avoid wrinkles setting in.
In summary: While the reference notes that traditional flannel often doesn't require ironing if air-dried, ironing "flannel fleece" (a term usually implying synthetic fleece) is generally ill-advised due to the risk of heat damage to the fibers. Opt for gentler methods like steaming or air drying instead.
