This is heterochromatic plush. The English name “colorful feather and down” refers to the colored plush among white goose and white duck down.
Duck down has been able to effectively solve the problem of heterochromatic down through the large-scale breeding of pure white ducks. White goose cannot be solved temporarily due to the small scale of breeding.
my country’s national standard GB/T 14272-2011 stipulates that among 95% of white goose down, 1% of heterochromatic down is allowed，As there is currently no effective and harmless method for sorting heterochromatic velvet，All white goose down products of well-known outdoor brands, including our company, have black heterochromatic velvet，Customers can check the comparison in such as Sanfu outdoor physical stores or large formal shopping malls，You will find that as long as it is a regular well-known brand of white goose down products, there is a phenomenon of heterochromatic down.。Ways to completely avoid heterochromia down’s product：One possibility is a very expensive manual picking method，another way to bleach down，Of course, there is white duck down instead of white goose down，This is an unwise choice！
