Fleece, also known as fleece fleece, is 100% synthetic material, although in English it means fleece, sheep wool. Fleece is valuable especially for being extremely soft, breathable and warm, making it an optimal choice for winter clothing. It gained popularity in the 1990s because it is warmer than wool and much lighter to wear.
Usually fleece is made of polyester (which is derived from plastic). Polyester filaments are produced by a chemical reaction involving oil and its derivatives. The chemicals are heated until a thick syrup is obtained, which then hardens and rotates to form filaments. Due to its fiber structure, the fleece is extremely warm and breathable and allows air to flow very easily through it. Polyester yarns weave a lightweight fabric that is further processed and cleaned to increase the fiber volume. Sometimes fleece incorporates some natural fibers, such as wool, hemp or silk, to create a specific texture to the fabric. Fleece can also be made of recycled plastics, such as plastic water bottles, making it an eco-friendly and inexpensive material.
The main feature of fleece is that it very successfully retains heat, thanks to the air pockets between its threads, and the fabric is also extremely moisture resistant, these qualities make it ideal for choosing a middle (of three main) layers of clothing to give us provide maximum comfort even in extreme weather conditions.
Fleece enjoys a very wide application. It is even used in the production of linen for astronauts. Its versatility makes it one of the most widely used textiles in the textile industry today. Fleece is the ideal material for sportswear because it removes sweat and moisture from the body, keeping athletes dry as air circulates through the fibers. It also very effectively prevents odors and perspiration. Its thermal insulation qualities make it ideal for winter clothing - blouses, jackets, thermal underwear, scarves, hats, gloves and more.
Fleece originated in the 1970s when Malden Mills developed polyester fleece, which is the basis for the creation of a modern version of the fabric today. Until then, Malden Mills were known as manufacturers of artificial leather and wool clothing. Subsequently, the company aims to produce a fabric that combines the insulating qualities of these fabrics, but to eliminate the problems that come with natural wool (eg weighing heavily when the complexity of the production of natural fabrics gets wet).
Malden Mills has partnered with Patagonia, an outfit maker, and the two companies market the so-called. Synchilla fleece - durable, wool-like fabric. Malden Mills owner Aaron Feuerstein decides not to patent this fleece, making it affordable for everyone and cheap to buy. Currently, the company already operates under the name PolarTec (PolarTec) and continues to produce the well-known material.
In summary, the advantages of fleece over the wave are that it is softer and lighter. Its main disadvantages are that it loses its thermal insulation properties when wet and static, ie. can attract dust, moss and any kind of fiber. The main advantages of the wave are that it is a completely natural material, is eco-friendly and insulates even when wet. However, it can cause allergies and itching.
