What's the difference between goose down and duck down? Which kind of goose down has good warmth ret

In recent years, the competition in down industry has been fierce, and the "goose duck competition" has become a hot spot of enterprise publicity and news media reports. So what's the difference between goose down and duck down? Which is better in keeping warm?

Odour contrast

We know that ducks belong to omnivorous animals. They can be used as food for ducks, no matter in coarse feed or green feed, or in insects, earthworms, fish and shrimp. Because there is much fat in the food, there is a lot of fat in duck down, which generally has a fishy smell. It is called "fat smell" or "duck fox smell" in the industry.

The feed of geese is mainly plant-based, and general weeds and aquatic plants can be used for geese. Therefore, there is little fat in velvet and almost no peculiar smell.

The smell has always been the focus of the contrast between goose down and duck down, but it is wrong to say that "duck down has more peculiar smell than goose down". Yao Xiaoman, President of China down industry association, thinks: 'the production and processing process of goose down and duck down are the same, and the goose down and duck down that meet the standards are tasteless and harmless, while the goose down and duck down that have peculiar smell do not meet the standards. '

Fluffy contrast

In the national supervision and spot check, the physical and chemical tests of goose and duck down with about 90% down content in different regions and producing areas were carried out. The results showed that the goose down was slightly larger, the fluffy degree was slightly higher than that of duck down, but the thermal performance was not different, while other indicators were not different.

Whether goose down or duck down, there are many factors that affect the fluffy degree of down. Under the same down content:

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.

The size of the down flower in the down will also affect the fluffy degree of the down. 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.

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.

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.

Comparison of goose and duck down products

No matter goose down or duck down, they are usually called down. They are used as fillers to make down clothes, duvet covers, down sleeping bags, etc. they are called down products. Because down products are soft, fluffy and warm, they are popular with consumers. So, goose down and duck down are both natural cold resistant products.

Duck down can produce up to three seasons a year, but goose down can only produce one season a year, and the yield of each goose is small. The high cost of goose breeding determines that the price of goose is much higher than that of duck. If buying goose down is to buy quality, then buying duck down is to buy material benefits. In terms of cost performance, duck down is more competitive than goose down. At present, domestic down products are mainly filled with duck down, which has been inspected by the market for many years and recognized by consumers. In developed countries, goose down is the main raw material for duvet, while duck down is the main raw material for down clothing.

There is a very important reason that the raw materials of down clothing at home and abroad are mainly duck down, because the clothing will be washed frequently, and duck down contains a lot of grease, which is a protective layer for down, which can make duck down keep a good fluffy degree after many times of cleaning. However, velvet contains less grease and is not resistant to water washing. More times of water washing can easily lead to separation of velvet and core, increase of velvet and decrease of fluffy degree. Once there were down manufacturers testing the down content of 90% velvet down clothing and 90% duck down clothing. After 20 washes, the down content of goose down clothing was 85% and that of duck down clothing was 89%.

Therefore, goose down has its own advantages and disadvantages, which can not be generalized, let alone distinguish the superior from the inferior.
