In the cold winter months, we often choose to wear down jackets to keep warm. So, why do down jackets provide better warmth?What factors affect the warmth effect of down jackets?
1. Why are down jackets warmer?
The reason why down jackets can provide better warmth is mainly due to their special material and structural design. The padding in down jackets is usually duck down or goose down, which has excellent thermal insulation properties. When down is filled in clothing, they form a soft layer of insulation that prevents cold air from the outside from entering the garment while slowing down the heat loss from within.
2. What factors affect the warmth effect of down jackets?
Fillers: The padding of a down jacket is a key factor that affects its warmth effect. Duck and goose down retain more warmth than other fillings because they have larger down and longer filaments, which create a thicker insulation. Therefore, choosing a down jacket with a filling of duck down or goose down can achieve better warmth.
Down content: Down content refers to the percentage of down filled in a down jacket. The higher the down content, the more down in the down jacket and the better the warmth. Generally speaking, the relevant national standards stipulate that the down content of down jackets shall not be less than 50%.
Filling volume: The filling amount refers to the weight of down filled in the down jacket. The higher the filling amount, the more down in the down jacket and the better the warmth. Therefore, when choosing a down jacket, you can choose the right amount of down according to your needs and budget.
Fill power: Fill power is an important indicator to measure the warmth performance of down jackets. The higher the fill power, the thicker the air layer in the down jacket and the better the thermal insulation. Therefore, when choosing a down jacket, you can choose a product with higher fill power.
fabrics: The fabric of the down jacket will also affect its warmth effect. In general, fabrics should be windproof, waterproof, and breathable. This keeps your clothes dry and comfortable, further enhancing your warmth.
In short, the reason why down jackets can provide better warmth is mainly due to their special material and structural design. Factors such as filling, down content, filling amount, fill power, and fabric will all affect the warmth of the down jacket. When choosing a down jacket, we should choose the right style and performance parameters according to our needs and budget to ensure the best warmth.
