A fabric created through a process of shrinking or felting knitted or woven wool. This technique involves subjecting the material to moisture, heat, and agitation, resulting in a dense, compact texture. The resultant textile displays a characteristic matted surface, concealing the original knit or weave structure. For instance, a loosely knitted woolen sweater can be treated in this manner to produce a substantially firmer and warmer outer garment.
The advantages of this treatment include enhanced insulation, wind resistance, and durability. Its compact structure provides superior warmth compared to standard woolen fabrics, making it suitable for cold-weather apparel and accessories. Historically, this treatment has been employed in crafting garments for outdoor activities, military uniforms, and protective gear, prized for its robustness and weather-resistant properties. Its longevity stems from the enhanced fiber interlock achieved during the manufacturing process.
