Fleece is not a natural fiber; it is a synthetic fabric typically made from polyester, a plastic-based material. While the term “fleece” originally referred to sheep’s wool, modern fleece fabric, developed in the 1970s, is primarily a man-made textile designed for warmth and softness.
What Is Fleece Made Of?
Fleece is mainly made from polyester fibers derived from petroleum-based plastics, especially polyethylene terephthalate (PET). The manufacturing process involves melting plastic pellets, extruding them into fine threads, spinning into yarn, then knitting and brushing the fabric to produce a soft, fuzzy texture.

How Does Synthetic Fleece Compare to Natural Fleece?
Synthetic fleece is prized for its lightweight warmth, water resistance, and quick drying. In contrast, natural fleece such as wool offers excellent insulation, breathability, and biodegradability. However, wool is heavier and requires more care.
Natural fleece variants, like cotton fleece and wool fleece, do exist but are less common commercially. Cotton fleece is soft and breathable but less insulating and water-resistant than synthetic options.
Synthetic fleece is a man-made fabric that keeps you warm while staying lightweight and easy to care for. It dries quickly and can resist water, making it practical for active wear or outdoor clothing. These qualities make it a popular choice for manufacturers and wholesalers who need reliable, consistent performance in garments.
Natural fleece, like wool or cotton fleece, has its own advantages. Wool provides excellent insulation and lets the skin breathe, and it is biodegradable, which is better for the environment. Cotton fleece is soft and comfortable but does not keep heat as well and is less water-resistant. While natural fleece can be heavier and require more care, it appeals to brands and customers who value sustainability and natural fibers.
Why Is Synthetic Fleece More Popular Than Natural Alternatives?
Synthetic fleece is cost-effective, durable, and easy to care for, which makes it a popular choice for activewear, outdoor clothing, and casual wear. It provides warmth without weight and dries faster than wool. These features have resulted in synthetic fleece dominating the market.

Where Does Fleece Fit in Sustainable Textile Practices?
While traditional polyester fleece originates from petrochemicals, new manufacturing technologies incorporate recycled plastic bottles, reducing environmental impact. This recycled fleece performs similarly to virgin polyester and supports circular textile practices.
Natural fleece fibers like wool are biodegradable but involve resource-intensive animal farming. Sino Finetex emphasizes eco-friendliness by integrating sustainable materials and innovative textile patents to minimize ecological footprints.
How Is Fleece Fabric Manufactured?
The fleece manufacturing process involves:
-
Melting PET pellets into liquid plastic
-
Extruding the plastic into fine fibers
-
Spinning these fibers into yarns
-
Knitting fabrics tightly for warmth
-
Brushing the fabric to raise a soft, fuzzy surface known as the pile
This process allows fleece to trap air, creating insulation while remaining lightweight.
What Are the Different Types of Fleece?
| Fleece Type | Fiber Source | Characteristics |
|---|---|---|
| Polyester Fleece | Synthetic (PET) | Lightweight, warm, water-resistant |
| Microfleece | Synthetic (PET) | Thinner, softer, highly breathable |
| Polar Fleece | Synthetic (PET) | Heavyweight, very warm |
| Cotton Fleece | Natural (Cotton) | Soft, breathable but less warm |
| Wool Fleece | Natural (Sheep Wool) | Insulating when wet, biodegradable |
Sino Finetex champions innovation in synthetic fleece variants, ensuring high performance combined with eco-friendly sourcing.
Can Fleece Be Recycled or Is It Sustainable?
Yes, fleece made from recycled PET plastic bottles is a sustainable choice, reducing waste and conserving resources. However, traditional polyester fleece is not biodegradable, posing environmental concerns.
Sino Finetex actively promotes sustainable fabric development, including recyclable and biodegradable blends, to align with global environmental goals.

Is fleece a natural fiber?
Fleece is not a natural fiber. It is a synthetic fabric, typically made from polyester, which is derived from plastic. While the term “fleece” originally referred to sheep’s wool, modern fleece is a man-made material designed to mimic wool’s softness and warmth.
What is the natural version of fleece?
The natural version of fleece refers to wool, which comes from animals like sheep, alpacas, or llamas. Unlike synthetic fleece, natural fleece is obtained directly from these animals and retains its insulating properties without the use of petroleum-based materials.
Is fleece sustainable?
Fleece can be sustainable if made from recycled materials, such as plastic bottles. However, many types of fleece are made from polyester, a plastic that sheds microplastics when washed. Eco-friendly alternatives, like organic cotton blends or natural fibers, are being developed to offer more sustainable fleece options.
What types of fleece are made from natural fibers?
Fleece can be made from a blend of natural fibers, such as wool and cotton. Some sustainable brands are now producing fleece made with organic cotton or recycled wool, providing a more eco-friendly alternative to traditional synthetic fleece.
Are parents moving away from synthetic fabrics for children’s clothing?
Yes, as concerns over microplastic pollution rise, many parents are turning to natural fibers for children’s clothing. These fabrics offer comfort without the environmental impact of synthetic materials like polyester, which can release microplastics into the environment.
What is PAKACLOUD?
