About down feathers
1. Origin of down feathers
As a filling material for down products, down feathers are derived from the body surface of ducks and geese, and belong to the by-products of the goose and duck meat food industry.
2. Duck down to goose down ratio
Among China’s total down production, duck down accounts for about 90%, and goose down accounted for 10%. The growth cycle of ducks is short, usually about 40 days, and can be incubated daily, each. The growth cycle of goose is long, which takes 5-6 months, and can only be hatched once a year. Therefore, the yield of duck is much higher than the goose.
Features of down
1. Down is natural
Down is a by-product of the poultry industry and contains at least 80% protein, making it a natural product that degrades naturally.
2. Down is sustainable
As people have a long-term demand for goose and duck meat, and down is the most comfortable and warm natural warm material, there is a stable market demand for down products, so the production of down feathers will be a permanent sustainable development.
3. Down has strong resilience and high shagginess
Chemical fiber, cotton, wool, silk and other linear fiber compression poor, easy to harden, material degradation fast; Down because of its three-dimensional spherical and rich in non-flowing air, perennial use will never harden, can ensure its function as new for a long time. The service life of the general edown quilt is 10-15 years, goose down quilt can be 20-30 years
4. Down has low flammability
Down is animal protein and will not burn at temperatures below 100 degrees Celsius, so it can pass the flammability test smoothly. But other materials, especially synthetic ones, need to be fire-resistant to pass the same tests; In California, the fire resistance of duvet is not tested.
5. The down has good moisture absorption and dampness
The three-dimensional spherical structure of down determines that its surface area is very large, so it will soon be released after absorbing water. In addition, down itself contains a certain amount of oil, with good hygroscopicity and hygroscopicity.
