2001 was the year with the fiercest competition in the down industry, and the "battle between goose and duck" became a hot spot in corporate publicity and news media reports. To this day, this controversy is still going on. Is it necessary to rigidly distinguish who is better and who is worse? Let's analyze the difference between goose down and duck down from various aspects.
Odor comparison We know that ducks are omnivorous animals, no matter roughage or green feed, insects, earthworms, fish and shrimp, etc. can be used as duck food.
Because the food contains fat, duck down contains a lot of fat and generally has a fishy smell, which is called "fat fishy" or "duck body odor" in the industry.
The feed of geese is mainly plant-based, and general weeds and aquatic plants can be eaten by geese. Therefore, goose down has less fat content and almost no peculiar smell.
Smell has always been the focus of the comparison between goose down and duck down, but some sayings that "duck down has a stronger smell than goose down" are not true. Yao Xiaoman, chairman of the China Down Industry Association, believes: "The production and processing processes of goose down and duck down are the same. Goose down and duck down that meet the standards are odorless and harmless, while goose down and duck down that have peculiar smells do not meet the standards. "
In the national supervision and random inspection, physical and chemical tests were carried out on goose down and duck down with a down content of about 90% in different regions and production areas. , while the other indicators showed little difference.
Whether it is goose down or duck down, there are many factors that affect the bulkiness of down. Under the same condition of down content:
The ratio of velvet to velvet in down will affect the fluffiness of down. The higher the proportion of velvet in down, the better the bulkiness and the better the quality of the down. On the contrary, the higher the proportion of down silk in the down, the worse the bulkiness.
The size of the fluff in the down will also affect the loft of the down.
The larger the velvet, the higher the fluffiness, on the contrary, the smaller the velvet, the lower the fluff, and the lower the down quality.
The moisture content in the down, that is, the degree of dryness, will also have an impact on the loft, and the drier down is always better than the less dry down.
The oxygen consumption index of down will also affect the bulkiness of down.
From the analysis of the above four factors, we cannot simply think that goose down is better than duck down. The key depends on the feather quality of the purchased goose down and duck down, followed by the process of goose down and duck down in the process of processing, as well as the means of quality control.
Comparison of goose and duck down products
Whether it is goose down or duck down, it is customarily referred to as down, and down is used as a filler to make down jackets, duvets, down sleeping bags, etc., which are called down products. Because down products are soft, fluffy and warm, they are deeply loved by consumers. Therefore, goose down and duck down are natural good products to keep out the cold.
Duck down can be produced up to 3 seasons a year, but goose down is only produced once a year, and the amount of down produced by each goose is relatively small. The higher cost of goose breeding determines that the price of goose down is much higher than that of duck down. If you say that you buy goose down for quality, then you buy duck down for benefits. In terms of cost performance, duck down has a more competitive advantage than goose down.
At present, domestic down products are mainly filled with duck down, which has been tested by the market and recognized by consumers for many years. Foreign developed countries mainly use goose down as the raw material for down quilts, while duck down is still the main raw material for down jackets.
There is a very important reason why duck down is the main raw material for down jackets at home and abroad, because clothing will be washed frequently, and duck down contains a lot of oil, which is a protective layer for down, allowing duck down to maintain good bulkiness after repeated washing .
However, goose down contains less oil and is not resistant to water washing. Too many times of washing will easily lead to the separation of velvet and velvet core, the increase of velvet and the decrease of bulkiness. A down manufacturer once tested goose down jackets with 90% down content and 90% duck down jackets. After 20 washings, the down content of goose down jackets was 85%, and that of duck down jackets was 89%.
Therefore, goose down and duck down have their own advantages and disadvantages, which cannot be generalized, let alone distinguish which is better and who is worse.
