Important Index Of Feather Down And Basic Requirements Of Down Jacket Fabric

(down coat) a jacket filled with plump stuffing, with a large and round shape.

The down jacket is more than half of the duck's feather, and it can be mixed with some small feathers. It can be cleaned and sterilized.

That's the down jacket.

The down jacket has better thermal insulation.

Mostly for people in cold areas, and also for polar expeditions.

Important index for measuring eiderdown

1. The amount of filling: the amount of filling is not an indicator of the quality of down. It refers to all the down garments.

Weight.

According to the target design, the filling amount of the general outdoor down jacket is about 250-450 grams.

2. The amount of cashmere (down content): the amount of cashmere is the proportion of down inside the pile. It is usually expressed in percentage.

The down weight of outdoor down garments is generally over 80%. On the surface of the data, the content of the cashmere is 80% and that of the feather is 20%.

Fill power: fluffiness is an important index for measuring the degree of thermal insulation of the down, which refers to the volume of cubic inch of each ounce (30 grams) down under certain conditions.

If the space of one ounce of eiderdown is 600 cubic inches, the feather is 600.

The higher the bulkiness of the down is, the more eiderdown of the eiderdown can be fixed with a larger volume of air layer for thermal insulation and heat insulation, so the warmth of the down is better.

Bulky degree is not a rigid index in China, and the relative error of measurement is also large.

1. Windproof and breathable: most outdoor down coats have certain windproof properties.

Ventilation is outdoor.

Unified requirements, but many donkey friends tend to ignore the importance of fabric ventilation.

The result of a breathless down jacket on high mountains is often fatal.

2. Anti velvet: there are three ways to enhance the anti fleece properties of down fabric. One is coating or coating on the base cloth, and preventing leakage through the film or coating. Of course, the primary prerequisite is air permeability, and will not affect the lightness and softness of the fabric.

Two, high density fabric can be treated through post processing to improve the fabric's anti fleece performance.

The three is to add a layer of anti velvet cloth in the down fabric, and the quality of the fabric will directly affect the quality of the whole garment.

3. Light and soft: today, the lightweight of fabrics will directly affect the overall weight of a down garment, and the softness of fabrics will enhance the comfort of down garments.

On the other hand, light and soft fabrics will help to bring down the fluffiness of the down, so the warmth retention will be higher.

Waterproof, mainly for professional feather clothing, which is directly worn out in cold weather. The fabric of down jacket should be used directly instead of the suit.
