The filling of down jackets is one of the important factors affecting the thermal insulation effect. Common down jacket fillings are mainly divided into two types: goose down and duck down.
1. Goose down: Goose down refers to the down feathers on the goose body. It has higher density and larger velvet, so it has better thermal insulation effect. Goose down has high thermal insulation properties, can effectively keep body temperature from being lost, and has a long service life.
2. Duck down: Duck down refers to the down feathers on the duck body. Compared with goose down, the velvet of duck down is thinner and the density of the down feathers is relatively low. Although the thermal insulation effect of duck down is slightly less than that of goose down, duck down is also one of the more common filling choices because it is more affordable.
In addition to the type of filler, there are several key factors that affect the thermal insulation effect of down jackets:
1. The filling amount of down and down: The greater the filling amount, the better the thermal insulation effect of the down jacket. Generally speaking, down jackets with a filling volume between 150g and 300g have better thermal insulation effects.
2. Quality of down: High-quality down filling has high thermal insulation performance. Good down feathers have uniform and fluffy velvet, which allows the filling to form more air isolation layers and increase the warmth retention effect.
3. Down weaving technology: The weaving technology of down filling during the production process will also affect the thermal insulation effect. By optimizing the weaving process, the density and wind resistance of the down can be enhanced, and the warmth retention effect can be improved.
4. Selection of fabrics: The selection of fabrics also has a certain impact on the thermal insulation effect of down jackets. Common fabrics include nylon, polyester fiber, etc. The fabric is lightweight, soft, waterproof and breathable, which helps to improve the thermal insulation performance of down jackets.
In short, the type, filling amount and quality of the filling, as well as the weaving process and fabric selection are all important factors that affect the thermal insulation effect of the down jacket. When customizing a down jacket, you can choose the appropriate fillers and fabrics according to your personal needs to achieve the best thermal insulation effect.
