Down is the best natural materials human havefound for keeping warm so far. It is made into down jackets after the procedures of washing, drying and grading etc. when referring to the thermal capacity, artificial material is there times lower than don. Then, what is down? Down is consisting of velvet (down) and feather. Down is the feather without the hard bars , the filaments of the feather branches cluster into each other, which forms into a stable thermal protection layer. Therefore, down is the main material of thermal maintain. Every ounce of down is about two hundred million filaments, the longer the filaments are the better the quality is, thus the velvet flowers are corresponding larger. While feather is the feather with small feather bars in the back and tail of a duck or goose, sometimes it is also made of broken feathers. In fact, because of the quality fluffing down, the number of feather mustn't be too large nor too small, it must remain a certain proportion.
According to the sources, down can be generally divided into two kinds - goose and duck down, according to the color, it can be divided ...
... into white and gray down. In addition, there is black down produced by Iceland. Relatively speaking, better down generally comes from the larger more mature animals, so the down from goose is better than that of duck, speaking from the colors, white down is more popular than gray down because of the advantages of light-colored fabric. Sometimes, we can the mark 90% white goose down in the down jackets' tag, which means the proportion of the ingredients. Generally speaking, the proportion of the ingredients ranging from 5% to 95%.
Then how can we measure down? An important indicator to measure down is cashmere charge. But let's make it clear that cashmere charge is not the standard to measure the quality of cashmere, it refers to the down weight that filled in a down jacket, the cashmere charge for general outdoor jackets depending on the certain design target different from 250 to 450 grams. He second is down content, down content is the ratio of down that is inside the pile, generally expressed as a percentage, the cashmere rate of outdoor down jackets is above 80%. The third is fluffy. Fluffy is an important indicator to measure the warm degree of down, it refers to the value per ounce (30 grams) of down. For example, if a ounce of down shares 600 cub inches of space, we say the degree of the fluffy is 600. If the degree of fluffy down is higher, which indicates that the same amount of charge under the feather flock can be fixed to a larger volume of air layer to keep warm , so the thermal capacity are better, fluffy is not a hard indicator measurement in domestic . What's more , it is easily to cause relative error.
