Down fabric is a kind of warm effect is very good fabric, especially suitable for cold season wear. The thermal insulation effect of down fabric mainly comes from the characteristics of down, which has high thermal insulation performance and low thermal conductivity. Below I will introduce the warm effect of down fabric in detail.
First of all, the thermal effect of down fabric comes from the excellent thermal characteristics of down itself. Down is a kind of wild bird on the body of the small hair, has the function of keeping warm. These fluff have a strong fluffy property, which is filled with many small air pockets, which can effectively retain heat, forming a good warm layer. The density of the fine fluff of down is relatively high, which can reduce the intrusion of cold air from the outside and provide better warmth.
Secondly, down fabric has a good thermal insulation effect because it has a low thermal conductivity. The fabric structure of down fabric is tight, there is a small gap between the fibers, and the thermal conductivity is low. Heat transfer is through collisions between molecules, and the smaller the gap between the fibers, the more difficult it is to transfer heat. In this way, the down fabric can reduce heat loss and keep the body warm.
In addition, down fabrics have good moisture permeability. Moisture permeability refers to the fact that the fabric can quickly discharge the moisture generated by the body and keep the body dry. The fine fluff in the down fabric has good ventilation and can smoothly discharge the moisture emitted by the body. Once the moisture can not be discharged, it will form water vapor inside the fabric, affecting the thermal effect. Therefore, the moisture permeability of down fabrics can help people keep their bodies dry and comfortable.
In addition, down fabric also has the characteristics of light and soft, very comfortable to wear. The down fabric is very light and will not cause pressure. At the same time, the fiber of down fabric is soft and has good bending, which can better fit the curve of the body and provide better warmth.
It should be noted that the warm effect of down fabric is affected by the quality and filling amount of down fabric. Different grades of down have different thermal ability, and the higher grade of down has better thermal effect. The more down fabric filling, the more dense the fluff, the better the warm effect. Therefore, when purchasing down products, it is necessary to pay attention to choosing high-quality down and filling enough.
In summary, down fabric has excellent thermal effect. It can retain heat and reduce heat loss through the fluffiness of down and the fine gap. The moisture permeability is enough to discharge the moisture of the body and keep the body dry; The light and soft features make it comfortable to wear. Of course, the warm effect of down fabric is also related to the quality and filling amount of down. Whether it is outdoor goods or winter clothing, choosing products made of down fabric can provide better thermal effect, so that people feel warm and comfortable in the cold season.
