Most of the problems are concentrated on the amount of “filling up”. Generally speaking, the amount of stuffed down refers to the total amount of eiderdown filled products. The amount of filling will directly affect the thermal insulation of down jacket. According to the national standard, the amount of filling should not be less than 95% of the marked value.
If the amount of filling is measured by the amount of eiderdown contained in a down garment, the quality of the down is measured. Velvet is commonly known as Duffy, is the most valuable part of the down, the higher the content, the better the quality.
Not only is the filling amount, we should pay attention to the “Cashmere volume” index when we choose the down jacket at ordinary times. The amount of cashmere is the proportion of down inside the pile, usually expressed in percentage. Popularly speaking, for example, the down weight of down garments is generally over 80%. This data shows that the content of feather down is 80%, and the content of feather is 20%.
Wang Zhuo, Secretary General of the China clothing association, believes that the higher the content of cashmere is, the better it is. The amount of cashmere and the amount of cashmere 90% contained in 70% is not much different.
