The resulting fabric is durable, lightweight, and has excellent resistance to wrinkles and shrinkage. Polyester is known for its ability to retain its shape well.
• Flannel: Flannel, on the other hand, is made from natural fibers, typically cotton. Cotton is a plant-based fiber that is spun into yarn and then woven to create the flannel fabric. The loose weaving or brushing process gives flannel its characteristic fuzzy texture. Being a natural fabric, flannel is breathable and comfortable to wear.

Texture

• Polyester: Polyester has a smooth texture, often with a slight sheen. It has a sleek and polished appearance due to its synthetic nature. The fabric feels less soft to the touch compared to natural fibers and lacks the fuzzy or plush feel associated with flannel.
• Flannel: Flannel has a soft and fuzzy texture that is highly appreciated for its cozy and comforting feel. The brushing or loosely woven process creates a surface with raised fibers, giving it a tactile and inviting sensation. Flannel’s texture is gentle and warm against the skin.

Manufacturing Process

• Polyester: Polyester is produced through a chemical process called polymerization, where petrochemicals are converted into long polymer chains. These chains are then spun into fibers that are used to create polyester fabric. The manufacturing process is highly controlled and involves the use of specialized machinery.
• Flannel: Flannel is manufactured using natural cotton fibers. The process begins with cotton cultivation, followed by harvesting, ginning, and spinning the cotton fibers into yarn. The yarn is then woven using a loom or subjected to a brushing process to create the characteristic fuzzy texture. Flannel production typically involves less chemical processing compared to polyester.

Durability

• Polyester: Polyester is highly durable and resistant to wear and tear. It has excellent strength and resilience, making it less prone to fraying or breaking.
