What is Fleece?

Fleece is a type of fabric made from polyester, which is a synthetic material derived from petroleum. The production of polyester and the manufacturing of fleece can have a significant environmental impact, due to the energy and resources required to produce the raw materials and the fabric.

Fleece is not biodegradable, so it can contribute to pollution when it is not disposed of properly. However, some companies have started producing fleece made from recycled plastic bottles, which can reduce the environmental impact of fleece production.

Fleece is considered less sustainable than natural fabrics such as cotton or wool.

How is Fleece Made?

Fleece is a type of synthetic fabric that is made from polyester, which is a synthetic polymer made from petroleum. The process of making fleece typically involves several steps:

Polymerization: The first step in making fleece is to create the polyester polymer by reacting ethylene glycol and terephthalic acid in the presence of a catalyst. This creates long chains of polymer molecules that will be used to make the fleece fabric.
Spinning: The polymer is melted and then extruded through small holes, called spinnerets, to form thin fibers. These fibers are cooled and stretched to align the polymer molecules, which makes the fibers stronger and more stable.
Crimping: The fibers are then passed through heated rollers, which causes them to shrink and curl, creating a fuzzy or hairy surface. This process is known as crimping.
Weaving or knitting: The crimped fibers are then woven or knit into the fleece fabric.
Finishing: The fleece fabric is then subjected to various finishing processes, such as dyeing, cutting, and sewing, to create the desired product.

Benefits of Fleece

Fleece fabric is a popular and versatile material with several advantages, including:

“Fleece is a hypoallergenic fabric, making it a great choice for those with sensitive skin”

Warmth: Fleece is known for its insulating properties and can keep you warm even in cold weather.
Lightweight: Fleece is lightweight, making it ideal for layering.
Softness: Fleece is soft to the touch and comfortable to wear, making it suitable for clothing, blankets, and other textiles.
Durability: Fleece is a durable fabric that can withstand wear and tear and retain its shape over time.
Moisture-wicking: Fleece has a high level of breathability, which helps to wick moisture away from the skin, keeping you dry and comfortable.
Quick-drying: Fleece dries quickly, making it a great choice for outdoor activities and sports.
Hypoallergenic: Fleece is a hypoallergenic fabric, making it a great choice for those with sensitive skin.
Easy to care for: Fleece is machine washable and easy to care for, making it a convenient choice for everyday use.
Versatile: Fleece is available in a wide range of colors and styles, making it a versatile choice for a variety of applications, including clothing, blankets, and home textiles.
Affordable: Compared to other fabrics, fleece is an affordable material, making it accessible to a wider range of consumers.

Negative Effects

Fleece, a type of synthetic fabric made from polyester, has several negative impacts on the environment:

Production: The production of polyester, which is made from fossil fuels, releases greenhouse gases.
Longevity: Fleece is not biodegradable, meaning it can remain in the environment for hundreds of years.
Microfiber pollution: Fleece sheds microfibers when washed, which can contribute to plastic pollution in oceans and waterways.
Water pollution: The production of polyester also consumes large amounts of water and generates chemical waste, which can pollute water sources.
Landfill: As it is not biodegradable, it ends up in landfills and stay there for centuries.
Animal welfare: The production of polyester may involve animal testing and the use of animal-derived products, which can be controversial from an animal welfare perspective.

Some companies have started to make fleece from recycled plastic bottles, which can be a more environmentally-friendly option.

Are harmful chemicals used?

The production of fleece, which is a synthetic fabric made from polyester, can involve the use of harmful chemicals. These chemicals can be used in various stages of the production process, including:

“chemicals can be toxic and harmful to human health and the environment”

Polymerization: The first step in making fleece is to create the polyester polymer, which involves the use of chemicals such as ethylene glycol and terephthalic acid. These chemicals can be toxic and harmful to human health and the environment if not properly handled and disposed of.
Spinning: The polymer is melted and then extruded through small holes, called spinnerets, to form thin fibers. The process of melting and extruding the polymer can involve the use of chemicals such as solvents, which can be harmful to human health and the environment.
Dyeing: Fleece fabrics are dyed in order to give them the desired color. Dyeing can involve the use of chemicals such as heavy metals, which can be toxic to humans and the environment.
Finishing: The fleece fabric is then subjected to various finishing processes, such as cutting, and sewing, which can involve the use of chemicals such as formaldehyde, which can be harmful to human health and the environment.
