2001 was the fiercest year of competition in the down industry, and the “Goose and Duck Controversy” became a hot spot for corporate propaganda and news media reports. Today, this controversy continues. Is it necessary to make a rigid distinction between who is better and who is inferior? Let’s analyze the difference between goose down and duck down in detail from many aspects.
We know that ducks are omnivorous animals. No matter roughage or green fodder, insects, earthworms, fish and shrimp, etc. can be used as duck food. Due to the high fat content in food, duck down contains more fat and generally has a fishy smell, which is called “fat fishy” or “duck body odor” in the industry.
The feed for the geese is mainly plant-based, and general weeds and aquatic plants can be eaten by the geese. Therefore, the content of goose down oil is low, and there is almost no peculiar smell.
Smell has always been the focus of comparison between goose down and duck down, but some saying that “duck down has a heavier odor than goose down” is incorrect. 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 spot check, physical and chemical tests were carried out on goose and duck down with a down content of about 90% in different regions and origins. The results showed that the goose down was slightly larger and the bulkiness was slightly higher than that of the duck down, but the warmth retention performance was similar. Large, while the other indicators are not much different.
Whether it is goose down or duck down, there are many factors that affect the bulkiness of down. Under the same conditions of down content:
The ratio of down and down in the down will affect the bulkiness of the down. The higher the proportion of down in the down, the better the bulkiness and the better the quality of the down. Conversely, the higher the proportion of down filaments in the down, the worse the bulkiness.
The size of the feathers in the down will also affect the bulkiness of the down. The larger the velvet, the higher the bulkiness, and the smaller the velvet, the lower the bulkiness and the poorer down quality.
The moisture content in the down, that is, the degree of dryness, will also affect the bulkiness. Dryer down is always better than less dry down.
The oxygen consumption index of down will also affect the bulkiness of down.
From the analysis of the above four factors, it cannot be simply considered that goose down is better than duck down. The key depends on the quality of the purchased goose down and duck down, and secondly depends on the process of goose down and duck down in the processing process, and the means of quality control.
Comparison of goose and duck down products:
Regardless of whether it is goose down or duck down, it is customarily collectively referred to as down, and down jackets, duvets, and down sleeping bags are made of down as a filler, 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 produce up to 3 seasons a year, but goose down only produces 1 season a year, and the down yield of each goose is small. The high 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 taste, then you buy duck down for good value. In terms of cost performance, duck down has a competitive advantage over goose down. At present, domestic down products mainly use duck down as the filling material, which is approved by consumers after many years of market inspection. Developed countries abroad mainly use goose down as the raw material of duvet, while the raw material of down jacket is still mainly duck down.
There is a very important reason that the raw materials of down jackets at home and abroad are mainly duck down, because the clothing will be washed frequently, and the duck down contains a lot of oil, which is a protective layer for the down, which can make the duck down to maintain a good bulkiness even after multiple washings. . However, goose down contains less oil and is not washable, and the number of washing times will easily cause the down yarn and the down core to separate, increase the down yarn and decrease the bulkiness. Some down manufacturers have tested 90% goose down jackets and 90% duck down jackets with down content. After 20 washes, the down jacket content of goose down jackets was 85%, and the down jacket content 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 who is good and who is bad.
