HISTORY:
The need for a lightweight, insulating, and moisture-wicking fabric for outdoor activities and cold-weather apparel drove the development of fleece. Initially, outdoor enthusiasts and athletes primarily used fleece in performance garments because of its excellent thermal properties and quick-drying capabilities.
The fabric gained widespread recognition and became a staple in outdoor apparel, including jackets, sweaters, and blankets. Fleece’s popularity also extended to other areas, such as casual wear and home textiles.
Over time, advancements in fleece manufacturing techniques and the introduction of recycled fleece made from post-consumer plastic bottles have contributed to its evolving sustainability profile.
Today, fleece continues to be a popular choice for a wide range of applications, offering warmth, softness, and moisture management. Its versatility and performance characteristics have made it a go-to fabric for outdoor adventures and cozy everyday wear.
PRODUCTION PROCESS:
Fleece is typically made from polyester, which is derived from petroleum. The first step is to produce the polyester polymer. This involves the polymerization of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) with ethylene glycol (EG) in the presence of a catalyst.
Once they obtain the polyester polymer, they melt it and extrude it through fine holes to create long filaments. They then cool and solidify these filaments, resulting in continuous polyester fibers.
The polyester fibers may undergo additional treatments to enhance their properties. This can include processes such as texturing, where the fibers are mechanically or chemically treated to give them a crimped or textured appearance. Workers spin the polyester fibers into yarn, which can be achieved through either ring spinning or the air jet spinning method, resulting in a bulkier yarn with more loft.
The yarn is then used to knit or weave the fleece fabric. Knitting is the most common method for fleece production, creating a fabric with a looped or brushed surface. The loops trap air, providing insulation and a soft texture. The fabric may also undergo additional processes such as shearing or brushing to enhance its softness and appearance.
