To make your DUVETICA, we need fabric, zips, buttons, thread, a few handfuls of valuable down cluster and a few grams of feathers.
However, there are different types of downs.
In fact, we would be better to differentiate between down and feather, as their difference is considerable. The feather, heavier and stiffer due to the presence of the calamus, which is very developed and stocky, is silky at the base with a very developed, flexible and slightly curved vexillum. The down presents itself as a real three-dimensional cluster without a central rod (rachis), typical of the feather; this cluster consists of a central core and numerous very thin elastic filaments that are at the base of its incomparable insulating power.
The down represents the noble part of the plumage, light and fluffy and, unlike the feather, is present in minimum quantities, from 20 to 35 grams at most. Hence, its great value. The weight of a single cluster can be up to 10 times lower compared to the weight of the smallest feather; therefore, it should come as no surprise that a single gram of goose down can contain over 500 of these clusters.
Duvetica purchases exclusively from suppliers that certify the origin of the feathers from by-products of the food industry.
This big difference means that the quality of a padding is defined by the quantity of down compared to the quantity of feather. While considering that there is a minimum presence of small feathers, the best padding consist of no less than 90% down and no more than 10% feathers.
That 10% is functional to enhance the characteristics of elasticity of the padding itself; a greater presence of down will inevitably correspond to a higher quality of the padding in terms of softness, lightness and volume.
We started saying that there are different types of downs.
The down is inimitable, unsurpassed in nature and there is no laboratory product that equals its isothermal and hygroscopic characteristics which give it unparalleled comfort.
Its qualities are usually determined by measuring the filling power in the laboratory, i.e. the capacity to occupy volume added to the capacity of elastic "return" after compression. The higher the filling power, the higher the performance of the padding in terms of lightness, warmth and comfort.
The size and density of the filaments of each single cluster determine its filling power; it is precisely this magic secret of the feathers that differentiates the clusters thanks to a long and complex artisanal and industrial work. It is the quality and the manufacturing process that determine the preservation of these characteristics and differentiate the value of the padding.
When it comes to down, the matter is simple: there are no "magic formulas" made of mixtures of different origins; the best down is undoubtedly goose down, with an ideal ratio of 90% down 10% feather.
Here, the magic happens and it is here that, from quality and love, your story begins.
