Is your down jacket warm?

I vaguely remember the first down jacket I bought many years ago. It feels much warmer than a normal jacket. Nowadays, many people will want to buy a down jacket in the winter to get a warm winter. However, many people clearly feel that the current down jacket is not as warm as it should have been. What is happening here? Today, Xiao Bian took everyone to see what is going on in the down jacket today.

The material of the down coat is mainly down and coated fabrics. The down fabric is composed of velvet and feather. The coated fabric is made of warp and weft high density silk, cotton, cotton and polyester fabrics. After the rolling, the space between the warp and weft yarns is reduced. , And then coated with a polymer slurry, so that it forms a transparent coating with the fabric to cover the gap, to close the fabric latitude and longitude gap. Some add fluorophos resin or silicone waterproof agent to the coating slurry, so that the fabric has anti-dew and anti-seepage properties.

When it comes to the quality of down jackets, two important indicators have to be mentioned, namely the amount of fleece and fluffiness.

The amount of cashmere containing cashmere refers to the amount of down in the cashmere, expressed as a percentage, generally containing 50 to 80% of the amount of cashmere. With high velvet content, the quality is good. At present, China is implementing the "National Standard for Down Clothing" (GB/T14272-2002), which stipulates that the amount of down clothing in down apparel products should not be less than 50%. Whether or not down jackets on the market have reached this target really needs to be considered.

Bulkiness Bulkiness is an important measure of down warmth and refers to the value of cubic inches of volume per ounce (30 grams) of feather down under certain conditions. The higher the dullness of the down, indicating that down in the same amount of down-filling can fix a larger volume of air layer to insulate and insulate, so the down warmth is better.

According to relevant media reports, the quality of the down jackets on the market today is uneven, and many down jackets do not contain the amount of cashmere. Many merchants, in order to reduce costs, often shoddy, and mix the feathers as fillers in the down, causing down jackets Easy to drill hair, down jacket is getting thinner, of course, will not keep warm. In addition, there are also many merchants choose the quality of down jacket fabrics, but the texture is too thin, or sewing thread processing is too rough, which is also an important reason for the overall quality down jacket.

So, what are our tips when buying down jackets?

1, by hand to intuitive feeling: If you touch a lot of hair, then that business is doped with a lot of feathers. However, be aware that if you do not touch any hairs, it is very likely that you will use a fly-filled down jacket. Flying silk is sessile short silk hair that falls off feathers during down processing. It is poor in warmth, and it has no bulkiness. It is agglomerated after washing.

2. Observe the elasticity of the down: If the down hand is pressed and the hand is released, it will soon be fluffy and return to the original state, indicating that the bulkiness of the down jacket is good. If you press the hand and then let go of the down jacket or flat face, you may not be able to buy the down jacket and the warmth is very low.

3, when buying down jackets can not ignore the quality of the fabric. Water-repellent coating (laminated) fabric is relatively rigid; if you use your fingers to cover the surface fabric, if you feel that there is a layer of cloth in the outer material, then add a fleece-proof cloth; the lightest and softest and only one layer is high density Water repellent fabric. There is a large number of fabrics used in the market, which are made of ordinary woven fabrics for anti-velvet treatment. The fabrics have poor air permeability, so try not to choose them.
