Duck down clothes need hand washing. Usually, there will be a small label printed with duck down ingredients and washing instructions on the inside of duck down clothes, and the small label will be printed with hand washing; If washed by machine, it will destroy the warmth retention and internal filling of duck down.

Down is divided into duck down and goose down, and the warmth retention of goose down is slightly higher than that of duck down under the same conditions. Down mainly has three performance indexes: 1 the index is the filling weight, such as 400g goose down sleeping bag and 1 100g duck down sleeping bag. This weight does not refer to the weight of the sleeping bag, but to the net weight of the filled down; The second index is down content. Down is composed of feathers and down. Feathers play an auxiliary role, and warmth mainly comes from fine down.
The cashmere content is expressed as a percentage, for example, 80 cashmere content means that the cashmere content in 100 weight unit is 80 units. Generally, the highest cashmere content of duck down is 85 to 90, and the cashmere content of goose down can reach 90 to 95. The third index is the expansion of down, and the filling power refers to how many cubic inches an ounce of down has under the pressure of 68.4 grams. The higher the swelling degree of down, the better the warmth retention of down.
