Three indicators of duvet quality: Quilt core: The duvet cores of duvets include white goose down, gray goose down, white duck down, gray duck down, goose and duck mixed down and crushed down. The quality of the quilt core mainly depends on its standard down content and down filling. Generally, the down content of down quilts is between 50% and 90%. The higher the percentage of pure down, the better the warmth retention of the duvet, and the higher the price. Usually it is better to be higher than 80%. Similarly, the higher the down filling, the better the warmth retention. Generally, the weight of the duvet (not including the quilt cover) is required to be more than 3 pounds. It should be noted that when purchasing, you should mainly read the marked down filling amount and down content. Fabric: The fabric of a duvet is generally required to be waterproof, velvet-proof, breathable and glossy. Common ones include lint-proof cotton, silk-cotton blend, nylon plastic-coated cloth, etc. Anti-down cotton cloth has been specially treated to prevent down from getting out easily and is more economical; nylon plastic-coated cloth has a firm texture and good warmth retention but poor air permeability. When selecting, you should also pay attention to the fact that the fabric should not have obvious flaws and yarn picks, and the seams and stitches should not be too sparse, otherwise the velvet phenomenon will easily occur. Feel: A good-quality duvet is fluffy and soft to the touch, with no obvious lint or stiffness. Pat the quilt lightly with your hands. There should be no obvious flying dust. If there is a lot of dust, it means the cleanliness is low and it is not suitable to buy. If there is any peculiar smell escaping, it is not advisable to buy it.
