Polar fleece

Polar fleece, usually referred to simply as "fleece," is a soft napped insulating synthetic fabric made from Polyethylene terephthalate (PET) or other synthetic fibers. Other names for this fabric are "Polar Wool," "Vega Wool," or "Velo Wool." Despite names suggesting the composition is made up of organic materials, fleece is 100% Polyethylene Terephthalate.

Uses[edit]

Polar fleece is used in jackets, hats, sweaters, jogging bottoms/sweatpants, cloth diapers, gym clothes, hoodies, inexpensive throw blankets, and high-performance outdoor clothing, and can be used as a vegan alternative to wool. It can be made partially from recycled plastic bottles and is very light, soft and easy to wash.[1]

History[edit]

One of the first[citation needed] forms was Polar Fleece, created in 1979 by Malden Mills, now Polartec LLC. This was a new, light, and strong pile fabric meant to mimic--and in some ways surpass--wool. Aaron Feuerstein intentionally declined to patent Polar fleece, allowing the material to be produced cheaply and widely by many vendors, leading to the material's quick and wide acceptance.[2][3][4]

Characteristics[edit]

Fleece has some of wool's finest qualities but weighs a fraction of the weight of the lightest available woolens.

Fleece garments traditionally come in different thicknesses: micro, 100, 200, and 300, with 300 being the thickest and least flexible.

A lightweight,warm and soft fabric, it is hydrophobic, holding less than 1% of its weight in water. It retains much of its insulating powers even when wet. It is machine washable and dries quickly. It is a good alternative to wool (of particular importance to those who are allergic or sensitive to wool ).It can also be made out of recycled PET bottles, or even recycled fleece. Despite its fuzzy appearance and feel, it is not flammable, but instead melts when exposed to flame.

There are disadvantages to this fabric as well. Its hydrophobic quality means it doesn't allow sweat to move through the fabric and evaporate during strenuous activity. Non-recycled fleece is made from non-renewable petroleum derivatives. Regular fleece is not windproof[5] and does not absorb moisture (although this is often seen as a benefit, per above).[6][7][8] Fleece also tends to generate a high amount of static electricity, which causes the accumulation of lint, dust, and pet hair. It is also susceptible to damage from high temperature washing, tumble drying or ironing. Lower-quality fleece material is also prone to pilling.
