Feather And Down Knowledge: Properties Of Down Garment Materials

The fabric is a functional fabric, and its performance requirements are higher than those of ordinary clothing. It has the functions of preventing down, escaping, windproof, waterproof, moisture permeable, breathable and so on. Besides, it has both a smooth appearance and soft handle, so that the down garment can not only be cold proof and warm, but also is beautiful, comfortable and light when it is taken.

In recent years, the pursuit of comfort and functionality of clothing has become a popular trend. The fabric of down jacket is particularly prominent.

In general, natural feathers can be subdivided into two types according to the growth parts of hairiness: Feather and feather. Wool refers to the outer part of the whole feather, which is a leaf like fiber. The length of the fiber is uneven. It is suitable for filling and filling materials as pillows, mattresses, and low down quilts.

It refers to the feathered feathers on the abdomen of ducks and geese, which accounts for less than 10% of all feathers, with light texture, low thermal conductivity and good fluffiness.

It is an ideal material for eiderdown garments.

As geese and ducks adapt to seasonal changes, their feathers will become large and dense in winter. They will become small and sparse in summer, so as to regulate body temperature and resist cold. The function of feather down is to imitate these birds' warming mechanisms.

Feathers are generally divided into two categories: wet feathers and wet feathers.

Wet feathers are mostly land birds that do not swim.

Feathers that are not wet: they are water birds, mainly feather goose, duck feather and so on. European, American and Japanese countries call them waterfowl feathers.

Different feathers have differences in warmth retention and fluffiness. For example, comparing with the same weight feathers, the expansion ability of white goose down is 1.67 times of that of duck eiderdown. The coefficient of expansion of these eiderdown will be directly related to the warmth retention effect of clothing.

Because of the tens of thousands of tiny pores on the down fiber, it absorbs the hot air emitted by the human body, so as to isolate the invasion of the cold air and prevent the loss of body temperature. Therefore, down is the most warm material in natural fibers.

In addition to its excellent insulation and elasticity, eiderdown has temperature regulation, humidity regulation, health and durability. The service life of eiderdown is very long, even for decades. Its thermal insulation will not be discounted due to time, and it will be very durable.

It is the lightest filling material in the world.

Lining characteristics of down garments

There are two main types of fabrics for Down garments, one is high-density fabrics, the other is fabrics with high density.

It can be directly sutured with inside without lining the gallbladder.

The other is the general fabric. This kind of fabric must be lined with gallbladder, otherwise the down will escape, especially when it is heated on the body, the appearance of down feather will be more serious.

Therefore, it is necessary to use this white, high-quality colourless cotton cloth as liner, on the one hand, to prevent feather from escaping, and on the other hand, it will not stain by fading.
