The G-LOFT® bi-component-fiber is permeated with a micrometer fine air channel. As a hollow fiber, it ensures as in nature the fur of polar bears, for optimum thermal insulation. The fiber consists of two different materials, which contract to varying degrees during cooling after spinning process. This creates a spiral shape – like a spring – which is permanently fixed in the molecular structure. Due to the “MEMORY-EFFECT” the G-LOFT® insulation returns always to its particularly warm, airy original shape. Whether duvet or outdoor apparel: Depending on the nature of the final product, the G-LOFT® bi-component-fibers are combined with a specific mix of micro- and melting fibers (Low-Melt-Fibers). The microfibers as full fibers provide a flatter structure and thus a smaller pack size. The low-melt-fibers are responsible for the lightness and flexibility of the G-LOFT® insulation: Thanks to THERMO-BONDING the outer shell merges with the other fibers, thus ensuring a permanent & soft loft. The G-LOFT® fibers form within the insulating layer, so-called “clusters”, as they are also found in high-quality goose down. Air is trapped in countless, small cushions, which provides an optimum lasting insulation in all directions. Thanks to this unique for synthetic fibers clustering, the G-LOFT® fiber has similar thermal characteristics as the natural down filling. Unlike down, however, the G-LOFT® fiber dries very quickly after washing and returns immediately to its original airy shape.
