Down jacket is most commonly filled with duck down. Now more and more manufacturers, down jacket is filled with velvet. And the price of down jacket is much higher than that of down jacket, so what's the difference between down jacket and down jacket?
Down jacket, goose down or duck down
There is no significant difference between the warmth retention rate of goose down and duck down, only in the fluffy index value, goose down is slightly higher than duck down 328cm3, that is, higher than 5%. Whether goose down or duck down, there are many factors that affect the fluffy degree of down. Under the same down content:
1. The fluffy degree of down will be affected by the proportion of down flower and down silk. The higher the proportion of down flower is, the better the fluffy degree is and the better the quality of down is. On the contrary, the higher the proportion of down silk is, the worse the fluffy degree is.
2. The fluffy degree of down is also affected by the size of down flower. The bigger the pile, the higher the fluffy degree. On the contrary, the smaller the pile, the lower the fluffy degree, and the lower the down quality.
3. The moisture content of down, that is, the degree of dryness, will also affect the fluffy degree. The fluffy degree of relatively dry down is better than that of less dry down.
4. The oxygen consumption index of down will also affect the fluffy degree of down.
From the analysis of the above four factors, it can not be simply considered that goose down is better than duck down. The key lies in the quality of the purchased goose down and duck down feathers. Secondly, it depends on the technological process of goose down and duck down in the processing process and the means of quality control.
What's the difference between goose down and duck down
Compared with duck down, goose down has large pile, high hollowness, good fluffy, excellent resilience and stronger warmth retention. According to the authoritative test data of China down industry association, the down flower of goose is generally larger than that of duck down, and the fluffy degree is 50% higher than that of duck down, so the thermal insulation performance is better. In addition, relevant experts also admit frankly that generally speaking, goose down is superior to duck down in all indicators.
When it comes to the difference between goose down and duck down, down experts point out that there are two aspects to the problem of duck down. One is that ducks like eating insects in water, so duck down generally has a smell of fishy smell (known as "duck fox smell" in the industry). In order to remove peculiar smell, some processing plants even use deodorant in the process of decontamination and degreasing. Although the newly purchased down jacket can't smell, it will return to taste after a few months, which can be naturally distributed at least one year later. Goose is a herbivore, so there is no peculiar smell in goose itself, which ensures the environmental protection from the source of raw materials.
The difference of warmth retention between duck down and goose down
Duck down and goose down have the same warmth preservation, which is not suitable for dry cleaning. It is learned that the warmth preservation of down clothing is related to the down content, fluffy degree, and down filling amount. According to GB / t14272-2002, down content refers to the percentage of the quality of down and down silk in the sample, and the warmth retention of down clothing is mainly the function of down. The proportion of the cashmere content determines the fluffy degree of the product, and then affects the warmth preservation of the product. It is stipulated that the cashmere content of the finished product is not less than 50%. The amount of down filling is the grams of down filling in the down clothing. The more down filling, the warmer the clothing.
There is no difference in warmth retention between duck down and goose down. Due to the cheaper price and better purchase of raw materials, many brands of down clothes mostly use duck down. There is no difference in warmth retention between white duck down and grey duck down, only the color is different. It is better to use white duck down for down jacket with light color fabric.
