Polar Fleece: Everything You Need to Know

What is Polar Fleece?

Polar fleece, commonly known as fleece, is a synthetic fabric made from polyester fibers. Introduced in the late 1970s, it quickly gained popularity for its ability to provide warmth without the bulk. It is widely used in outdoor and activewear, valued for its insulating properties and ease of care.

Characteristics of Polar Fleece

Polar fleece is known for its soft, plush texture and excellent warmth retention. The fabric is created by knitting polyester fibers into a light, airy structure, which is then brushed to create a fuzzy surface. This brushing process helps trap air, enhancing the fabric’s insulating capabilities.

Production Process of Polar Fleece

1. Fiber Creation: Polar fleece starts with polyester fibers, often made from recycled plastic bottles. The polyester is melted down and extruded into fine fibers.
2. Knitting: The polyester fibers are knitted into a fabric, creating small loops that help trap air and provide insulation.
3. Brushing: The knitted fabric is brushed on one or both sides to raise the fibers and create a soft, fluffy texture.
4. Finishing: Additional treatments enhance performance, such as anti-pill treatments to prevent fiber balls on the fabric’s surface.

Types of Polar Fleece

1. Microfleece: Lightweight (100-200 gsm), breathable, used for base layers and activewear.
2. Mid-Weight Fleece: Medium weight (200-300 gsm), versatile for various applications, commonly used for jackets and vests.
3. Heavyweight Fleece: Over 300 gsm, provides maximum warmth, ideal for heavy-duty jackets and outdoor gear.
4. Sherpa Fleece: Mimics sheepskin with a fluffy texture, often used as a lining for extra warmth.
5. Bonded Fleece: Two layers of fleece bonded with a windproof or waterproof membrane, suitable for outdoor jackets and performance gear.

Advantages of Polar Fleece

1. Good Elasticity: The stable knit structure of polar fleece provides excellent elasticity, making it resistant to deformation.
2. Warm and Comfortable: The dense, fluffy fibers of polar fleece offer superior warmth and softness, perfect for winter wear.
3. High Knitting Versatility: Polar fleece can be knitted into various patterns and easily dyed in vibrant colors to meet diverse preferences.
4. Resistant to Cold, Flame, and Static: Polar fleece is cold-resistant, flame-retardant, and anti-static, offering high safety.
5. Machine Washable: The fabric is durable and maintains its quality after washing, making it convenient for machine washing.

Disadvantages of Polar Fleece

1. Prone to Dust: The large, fuzzy fibers of polar fleece can attract dust, making it less suitable for individuals with respiratory sensitivities.
2. Allergy Risk: Some people may experience allergic reactions to polar fleece, and low-quality fleece can exacerbate conditions like asthma.
3. Higher Cost: The complex production and processing of polar fleece result in higher manufacturing costs and retail prices.
