Granular fleece fabric retains its breathability due to its unique structure and the properties of the materials used in its construction. Here's why granular fleece fabric remains breathable:
Microfiber Composition: Granular fleece is typically made from microfiber polyester or a blend of microfiber materials. These microfibers are much finer than natural fibers, and they have a high surface area to volume ratio. This allows for better moisture management and breathability.
Textured Surface: The granular texture on one side of the fabric, which gives it its name, plays a crucial role in enhancing breathability. This texture creates small air pockets or channels between the raised granules. These air pockets allow for the circulation of air and moisture vapor. As a result, excess heat and moisture generated by the body can escape through these channels, keeping the wearer dry and comfortable.
Moisture-Wicking Properties: Microfiber materials, such as those used in granular fleece, have inherent moisture-wicking properties. They can effectively pull moisture (sweat) away from the body and disperse it across a larger surface area of the fabric. This process accelerates the evaporation of moisture, preventing it from accumulating on the skin.
Quick-Drying: Because granular fleece fabric efficiently transfers moisture to its outer surface, it dries quickly. This rapid drying process helps maintain comfort during physical activities or in humid conditions. Wet fabric can feel uncomfortable and reduce breathability, but granular fleece minimizes this issue.
Non-Restrictive Design: Breathability is not solely determined by the fabric itself but also by the overall design of the garment. Granular fleece garments are often designed with proper ventilation, such as zippered vents or mesh panels, to enhance airflow and improve breathability.
Layering Compatibility: Granular fleece's lightweight nature and breathability make it an excellent choice for layering. When used as a mid-layer beneath a breathable outer shell, it helps manage moisture effectively and prevents overheating.
Versatile Applications: Granular fleece fabric is used in various applications, including sportswear, activewear, and outdoor gear. These applications require fabrics that can handle varying levels of physical activity and environmental conditions, making breathability a key consideration.
In summary, granular fleece fabric retains its breathability primarily due to the combination of microfiber composition, textured surface, moisture-wicking properties, quick-drying nature, and its use in versatile applications. These factors work together to ensure that moisture and heat can escape from the fabric, making it comfortable to wear during a wide range of activities and conditions.
