60+ days

28~35 days

1. The velvet color of ducks (goose) that has been cultivated for more than 60 days is very white, but it cannot be guaranteed that 100% are pure white, containing about 0.1% black velvet. This is because the white ducks (geese) that have been reared for a long time will grow different-colored down on their bodies, just like people will grow white hair when they are old.

2. Duck (goose) 28~35 days of breeding has small velvet, no black velvet, but yellowish color, because the growth time is short, the heterochromatic velvet does not grow, but there are many immature velvet, so the color is yellowish. Pure white is not achieved.

1. Bulkiness is a key indicator of the quality of down. Down products are mainly based on the fluffy effect of the finished product, that is, the degree of expansion; this is destined to be measured by volume rather than weight.

2. A piece of clothing filled with 80 grams of high-fluffy down is better than 100 grams of low-fluffy down. The unit price of down with high bulkiness is higher than that of down with low bulkiness, but the amount of down with high bulkiness is less and the total cost is almost the same; and the finished product is made of down with high bulkiness, and customers feel much better to the touch. , it is also much easier to recommend.

3. The higher the bulkiness, the better the quality of down. Japan, where down products are widely used, is the most important indicator of down with the level of bulkiness.

4. The test method of bulkiness should be tested by steam reduction method to be accurate. The oven method adopted in GB/T 14272-2011 standard fails to truly test the original bulkiness of down.

1. The inspection methods and assessment indicators adopted by the GB/T 14272-2011 standard are difficult to detect the quality of down and down, and the content of down and feather silk is not assessed, and the standard parameter for bulkiness is low; therefore, GB/T 14272-2011 standard There are deficiencies and imperfections.

2. Down with a lot of down silk and feather silk content will easily mislead the inspection during the inspection process, which will increase the down and down content. But down silk and feather silk are the culprits of drilling down. The more down and feather silk content, the lower the bulkiness.

3. The standard parameters mislead the monitor of the clothing brand only to see the test results, not to pay attention to the bulkiness.

Dust is a major problem in down processing plants. Since the standard has no assessment indicators to measure, through the detection of special dust removal detection instruments, the down dust content in the market is around 1.5% to 5%. This kind of down can be clearly seen in the down filling room and down filling machine. The dusty down drills a part of the down through the fabric when it is filled, and when it is filled in the down filling room, it is white. A large amount of off-white powder has accumulated on the wall of the down filling machine. This kind of down is made into a finished product. After washing, the light-colored down jacket becomes mottled like a map; while the down quilt is covered by the human body, which can cause coughing and allergies when people inhale dust.

1. Goose is a herbivore, and goose down has a small oil content, so goose down has no fishy smell.

2. The smell of grey duck down is better than that of white duck down. The duck down of free-range ducks smells better than that of captive ducks. The longer the ducks are raised, the less smell. Ducks that are 28 to 35 days old have the greatest down odor.

The less down silk, feather silk and neck hair in the down, the better.

1. In recent years, the GB/T 14272-2011 standard has been applied. Most manufacturers take advantage of the standard, the market supervision is not enough, the quality inspection agency is not professional, there are many indicators that have not been assessed and tested, the adulteration of down is very serious, and the market is of good quality. There is very little down, causing speculative manufacturers to hype imported down.

2. China is a major country in the world's down industry. 85% of down is produced in China. Many down are exported from China to Japan and Taiwan, and then exported from Japan and Taiwan to all over the world. Then part of the down is imported back to China. Therefore, most of the so-called imported down is also produced in China. For example, raw materials from Southeast Asian countries are now imported back to mainland China through Vietnam.

3. To process high-quality down, the raw materials must be fresh. The "golden 6 hours" of down means that it only takes 6 hours for the down from the duck (goose) to be depilated from slaughtering to the finished down. Such down can achieve first-class quality. Fewer down silk and down, and high bulkiness. Not to mention the origin of these downs, the imported raw materials have been stored and compressed for a long time, coupled with climate change, and the quality of down and feather silk is not good.

4. The duck (goose) down in the world is obtained from ducks (geese) that have grown for a certain period of time. There is no national border. Good raw materials are good raw materials wherever they come from, but good raw materials need to be processed and processed in time. Only with technical processing can we make good quality down.
