Fleece is a synthetic fabric that is typically made from polyester, specifically a type of polyester called polyethylene terephthalate (PET). Polyester is a type of plastic, the same material used to make plastic bottles. Fleece is known for its soft and cozy texture, making it a popular choice for winter clothing, sportswear, and home textiles like blankets and pillows.
While the majority of fleece is made from polyester, there are also variations that incorporate other fibers such as cotton, hemp, and rayon. These additional materials can be woven into the fleece to create distinct textures or add vibrancy to the fabric. However, the primary component of fleece is still polyester, which provides its insulating and moisture-wicking properties.
