　　 Down Jackets Keeping warm is the most popular topic nowadays. Is your down jacket warm during the Spring Festival? Vaguely remember the first down jacket I bought many years ago. It really feels much warmer than ordinary cotton padded jacket. Nowadays, when winter comes, many people will want to buy a down jacket to warm the winter. But many people obviously feel that the down jacket is not as warm as expected. What is the matter?

Feather and down fabrics are mainly made of down and coated fabrics. The down is made of cashmere and feather. Silk, Cotton, cotton and polyester fabrics are compressed by rolling to shrink the gap between warp and weft yarns, and then coated with polymer paste to form a transparent film covering layer with the fabric to seal the warp and weft gaps of the fabric. Some fluorinated phosphorus resins or silicone waterproof agents are added into the coating slurry, so that the fabric has the properties of dew proof and water penetration resistance.

When it comes to the quality of down jacket, 2 important points have to be mentioned. index That is the amount of fluffy and fluffy.

　　 Cashmere content

Cashmere content refers to the content of the down pile, which is expressed in percentage, and the average cashmere content is 50 to 80%. The quality is good with high content of cashmere. At present, China implements the national standard for Down garments (GB/T14272-2002), which stipulates that the down weight of down garments should be no less than 50%. Whether the down jacket on the market has reached this index really needs to be considered.

　　 Fluffiness

Bulky degree is an important index for measuring the degree of thermal insulation of the down. It refers to the volume of cubic inch of each ounce (30 grams) down under certain conditions. The higher the bulkiness of the down is, the more eiderdown of the eiderdown can be fixed and a larger volume of air layer for thermal insulation and insulation. Keep warm The better sex.

According to relevant media reports, the quality of the down garments is uneven nowadays, and many down garments are not up to standard. Many businesses often use shoddy clothes to reduce costs, and feathers are mixed into feather as stuffing, which makes it easy to drill down hair, and the down jacket is getting thinner and thinner. Of course, it does not keep warm. In addition, many businesses choose the quality of the down garment fabric is not good, the texture is too light, or the treatment of sewing thread is too rough, which is also an important reason for the overall quality of down jacket.

So, what are the tips for buying down coats?

1, through the pinch of intuitive feeling: if you touch a lot of Mao rod, it means that merchants doped a lot of feathers. But it is important to note that if you can't get any hair stalks, it is quite possible to use flying silk filled down garments. Flying silk is a sessile short silk hair that has fallen off feathers in the process of down processing. It has poor thermal insulation and no fluffiness.

2, observe the resilience of feather down: if the down hand is pressed and the handle is released, it will quickly fluff up and return to its original state, indicating that the fluffy degree of down jacket is good. If you press it with your hand and then leave it down or flat, you may buy a down jacket with insufficient filling and low warmth retention.

3, the quality of fabrics should not be neglected when choosing down garments. Waterproof coating (coated) fabric is relatively hard; finger sipping the surface fabric, if it is obviously felt in the outer layer of cloth, it is added anti velvet cloth; the most light and soft and only one layer is high density anti splashing fabric. There is a large number of fabrics used in the market, which are treated with ordinary woven fabrics as anti fleece. The permeability of fabrics is very poor, so try not to choose them.
