All Season Goose Down Alternative Duvet Comforter Insert - NTBAY

A: Down alternative material = FEATHER FABRIC FEATHER FABRIC is an ultrafine chemical fiber commonly used in the production of insulation materials due to its soft and delicate properties. It has excellent hand feel and warmth retention, with a thin and dense fiber layer that can lock in air and create a stable static air layer, providing warmth and cold resistance. Feather velvet is different from natural down in that it is an ultrafine chemical fiber with lower density and finer fibers. It is made softer and smoother by adding silicone oil, resulting in a better tactile sensation. At present, the common specifications of ultrafine fibers in the domestic market are between 0.8-2.5D, among which 0.8D ultrafine feather velvet fiber is favored due to its excellent performance. The fineness of feather velvet fibers is much lower than the common four hole and seven hole fibers on the market, which makes feather velvet products have better warmth and fluffiness, while being easy to wash and store, and less prone to mold and mites.
