We all know that a down blanket is a lightweight and warm product in the core, but it is also a down blanket. Some are labeled with duck down, while others are labeled with goose down. Why is there a significant price difference between the two? Below, the editor of Anhui Hongnuan Down Company will take you to understand the difference between goose down and duck down.
When it comes to down, we first need to understand several key indicators of down, and then analyze the difference between goose down and duck down based on these indicators.
Plush content: Plush content refers to the amount of "down" in down. Generally speaking, the higher the down content, the lighter the weight, and the better the warmth retention. We can see on the washing label of the purchased down quilt/clothing that the down content is 80%, 95%, etc. A high-quality quilt core with a minimum down content of 90% is required, while a regular down quilt has a down content of 95%.
Filling amount: The filling amount is not an indicator to measure the quality of down, but it determines the value of this down blanket or down jacket because it represents the weight of down. Under the same condition of down content, the higher the filling amount, the more static air it can hold, and the stronger the warmth retention.
Fluffy degree: Fluffy degree is an important indicator to measure the warmth retention of down. The standard stipulates that an ounce (approximately 28.34 grams) of down takes up 600 cubic inches of space (1 inch is approximately 2.54 centimeters), indicating a fluffy degree of 600. Namely, under the given weight of down, the larger the space occupied, the better the fluffiness and warmth retention.
Why is goose down more expensive than duck down?
Fleece is larger: As we mentioned earlier, the important indicator for measuring the quality of down is fluffiness. Compared to duck down, mature goose down has longer filaments, larger plush buds, higher fluffiness, and higher comfort, resulting in better quality and relatively higher prices.
The authoritative test data from the China Down Industry Association shows that the plush buds of goose down are generally larger than those of duck down, and the fluffiness is 50% higher than that of duck down, so the thermal insulation performance is more excellent.
Full velvet: Generally, the growth period of geese is at least 100 days until maturity, while for ducks it takes 40 days, so the velvet of geese is fuller than that of ducks.
The smaller the number of plush buds in 1 gram of velvet, the larger the individual plush buds, indicating a higher maturity of the velvet. Conversely, it indicates less maturity and shorter growth time.
Excellent fluffiness: The feather branches of goose plush are evenly distributed with smaller rhombic nodes, while the rhombic nodes on duck plush are larger and concentrated at the end of the small feather branches, so goose plush can produce a larger distance space, with better fluffiness and stronger warmth retention.
Better rebound: Goose feathers have better curvature, are thinner and softer than duck feathers, have better elasticity, and have stronger rebound.
A simple method to test resilience: Press the fluffy down blanket/clothing once, then release it, and quickly rebound to its original state, indicating that the fluffiness of the down is good.
No odor: Goose is a herbivorous food, while ducks are omnivorous, so the odor of goose down is much smaller. After treatment, there is basically no odor, and duck down is more or less a bit. Of course, if there is a pungent odor, it is a quality issue with the down itself.
Another key quality is that goose down has a longer lifespan than duck down. Duck down has a lifespan of about 10 years, but goose down can last for over 15 years.
