    How To Distinguish Plumes And Velvet?

    Down

    Birds' feathers can be classified into feather and velvet.


    Feathers have a central axis in their feathers, called "feather axis", while the "feather axis" has two rows of hard "feather branches" called feathers.

    The main function of "feather" is to stir up air in bird flight, help to fly and support the bird body in high altitude.


    "

    Velvet

    "Feathers" are not feathered feathers. They are gathered by a lot of slender and soft fibers in a central point and connected to the body of birds.

    When the filament of each central point is dispersed in the air, it looks like a flower, so it is called "velvet flower". The main function of "Cashmere" is to keep the body temperature of birds.


    Birds or poultry have plumes, but only waterfowls and birds that live in water for some time in life have "velvet", such as ducks and geese.

    "Velvet" mostly grows in the chest, abdomen, neck and armpit of waterfowl.

    The main thing is keeping the temperature of waterfowl swimming.


    "

    Velvet

    "Is the only natural best and the lightest insulation material.

    "Velvet" itself can not produce heat energy, its main insulation function is because each velvet flower has many soft velvet silk. When the fleece is spread, a three-dimensional POM ball is formed, and the best temperature insulator air is wrapped in the pouch. Thus, it becomes a top warmer bag. Besides preventing the body temperature from escaping, it can also resist the invasion of the cold air outside.


    Birds already know how to use "

    plume

    "And"

    Velvet

    When the cheeks were stealing birds eggs, they found that the mixture of "feather" and "velvet" was very soft, comfortable and warm. They began to collect "velvet" to apply to warm clothing and clothing.


    At present, most of the "velvet" used by humans are collected from water fowls, such as ducks and geese. In terms of volume, goose down is larger and the price is higher. The main reason is that the cost of raising goose is more expensive.


    In terms of warmth, there is no difference between eiderdown and goose down.

    Because "velvet" itself can not produce heat.

    The degree of warmth retention depends mainly on the following factors:


    1. The fluffiness of the "velvet" itself has a direct impact on the number of air that can be wrapped up with the best insulation.


    2, the number of "velvet" contained in the finished product.


    3, the design of clothing, including the fabric, style and structure of clothing.


    Due to the protection of consumers' interests and the degree of product warmth, different regions and countries have different specifications.

    It is also required that each finished product need to clearly specify the amount of cashmere and the ingredients of the finished product on the label.


    Under normal circumstances, the commercial size of the 80/20 goose should be 500 cubic inches in fluffy condition. The higher the bulkiness is, the better the degree of warmth. These high-quality products are embroidered with 600 or 700 words respectively.
