Down manufacturers said that the controversy between duck down and goose down did not last long. The debate continues to this day. Is it necessary to strictly distinguish who is good and who is bad? The following down wholesale manufacturers analyze the difference between goose down and duck down from various aspects.
1. Volume comparison
During the national supervision and random inspection, physical and chemical tests were carried out on about 90% of goose and duck down content in different origins and origins. The results show that goose down is slightly larger than duck down and has a slightly higher bulkiness, but has similar thermal insulation performance, while other indicators have no significant difference.
2. Smell comparison
We know that ducks are omnivores, whether it is roughage or green feed, or insects, earthworms, fish and shrimp, etc. can be used as duck food.
Because there is more fat in the food, duck down has more oil and fat, and generally has a fishy smell, which is called "fatty smell" or "ducky smell" in the industry.
The feed of geese is mainly plant-based, and generally weeds and aquatic plants can be eaten by geese. Therefore, goose down has less oil and almost no odor.
Smell has always been the point of comparison between goose down and duck down, but the statement that "duck down is more smelly than goose down" is not true. Yao Xiaoman, secretary-general of the China Down Industry Association, said: "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 have peculiar smell and are not up to standard.
Whether it is goose down or duck down, there are many factors that affect down filling. Under the same down content:
The ratio of tufts to filaments in down affects how lofty the down is. The higher the proportion of down buds in the down, the better the loft and the better the quality of the down.
Conversely, the higher the proportion of down in down, the poorer the loft. The size of the tufts in the down also affects the loft of the down. The larger the down, the higher the loft, and the smaller the down, the lower the loft, and the lower the quality of the down.
The moisture content of down, known as dryness, also affects loft. Drier down is always better than less dry down, and the oxygen consumption index of down also affects the loft of down.
From the analysis of the above four factors, we cannot simply think that goose down is better than duck down.
The key lies in the quality of wholesale white duck and goose down. Secondly, it depends on the technological process and quality control methods of goose down and duck down during processing.
The comparison between goose down and duck down products, whether it is goose down or duck down, is customarily called 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 products to keep out the cold.
Duck down is produced three seasons a year, while goose down is produced only once a year, and the output of each goose is very small.
The high cost of goose breeding determines that the price of goose down is much higher than that of duck down. If you buy goose down for taste, it is more affordable to buy duck down. In terms of cost performance, duck down is more competitive than goose down.
At present, domestic down products mainly use duck down as the filling material. After years of market testing, it has been recognized by consumers. Foreign developed countries mainly use goose down as the raw material for duvets, while the raw material for down jackets is mainly duck down.
The main raw material of domestic and foreign down jackets is duck down. There is a very important reason, because the clothes will be washed frequently, and duck down contains a lot of oil, which is the protective layer of down and allows ducks to be washed many times.
Goose down contains less oil and cannot be washed. Excessive washing times will easily cause the hair to separate from the core, increase the hair volume and reduce the bulkiness. A down manufacturer tested 90% goose down and 90% duck down.
After 20 times of washing, the down jacket found that the down content of the goose down jacket was 85%, and that of the duck down jacket was 89%. Therefore, goose down and duck down have their own advantages and disadvantages, and they cannot be generalized, let alone distinguish which is good and which is bad.
