How are down and feathers processed into bedding articles?

The raw down and feathers must be processed before they may be used as filling material for bedding articles.
First of all, the raw down and feathers are cleaned of coarse dirt. Then they are placed in special washing machines and undergo 6 to 8 washing cycles using a specific detergent suitable for bedfeathers.

In a next step, the down and feathers are dried and sterilized in a steamer at temperatures exceeding 100 °C.
After the drying process they are placed in the dedusting machine to remove fine dust which has not yet been cleared during the washing cycles and are cooled down to normal temperature.
Finally, the down and feathers are sorted. The basic types obtained from sorting are used to confect special down and feather blends according to the customer´s order.
 

The requirements for the hygienic state of the filling material are specified in EN 12935. The Daunasan® / Downafresh® brand indicates that bedding articles labelled with this brand are consistently monitored by means of mystery shopping to ensure at the best that products labelled with Daunasan® / Downafresh® meet the hygiene requirements.

How can down and feathers be sorted?

In the separation process down and feathers are sorted with the aid of air which is blown into a special sorting machine consisting of three or four chambers. The airflow generated in the machine achieves that due to gravity the single components fly different distances. The lightest components fly the longest distance and the heaviest elements fly the shortest distance. Correspondingly, the lightest parts, i. e. the down, fly the longest distance and get into the posterior chamber whereas the heaviest parts, i. e.

The different components can be separated by varying the intensity of the airflow.

What blends of down and feathers are most suitable?

The appropriate blend depends in particular on the individual need for warmth when asleep. Nowadays, most people usually prefer a high percentage of down.
 
Lightweight down provide best fill power values and a high degree of thermal insulation. With a higher percentage of feathers, the weight of the duvets increases, because feathers are heavier than down.
 
Due to large fill power values down are capable of being able to keep the body warm without much weight, that is to say the bulking capacity.

Due to large fill power values down are capable of being able to keep the body warm without much weight, that is to say the bulking capacity. A down-filled duvet always contains a blend of down and insulating air-filled pockets. The air-pockets among the single down make the duvet lightweight in relation to its volume. Thus, a down-filled duvet can keep the body warm and comfortable with very little weight.
 
Therefore, down satisfy all requirements for a perfect sleeping comfort: They are light and assure an excellent climate regulation. Pleasant warmth is quickly created and the perspiration absorbed is steadily being eliminated.
 
There are different types of down-filled duvets available. Depending on the filling weight they are manufactured for summer or winter.
Especially, a duvet containing 100 % of down keeps the sleeper pleasantly warm and cosy with very little weight at the same time. Another favoured blend consists of 90 % down and 10 % feathers.
Pillows, however, require a filling material which is able to support the head. In this case, feather-down blends are preferred, but more and more people, however, prefer a soft down-filled pillow.

Down duvet and feather duvet – what are the differences?

As stipulated in the European standard EN 13186, duvets with a down content of at least 60% may be labelled as down duvet. Duvets with a down content below 60% are labelled as feather duvets.

Which are the characteristic features of feathers and down from poultry?

 
Feathers and down from waterfowl (geese and ducks) are a unique natural resource of high quality. Used as filling for quilts, pillows and clothing, this material is distinguished by qualities such as breathability, humidity transport and thermal insulation together with a low weight.
 
Feathers and down from waterfowl (geese and ducks) are a unique natural resource of high quality. Used as filling for quilts, pillows and clothing, this material is distinguished by qualities such as breathability, humidity transport and thermal insulation together with a low weight. These special features account for the homogeneous distribution of feathers and down, for instance, in a quilt as well as for the fact that already small amounts of feathers and down are sufficient for the filling of a quilt.

What is the difference between down and feathers

The structure and appearance of down and feathers are quite different. A down has a soft centre from which all the light fluffy filaments protrude. Feathers have a long and curved quill which makes them resilient in a way, at the same time providing them with the ability to expand back to their original shape after having been exposed to pressure. Thus, in contrast to down feathers are perfectly suited as filling material for pillows as they softly cushion the head at the same time supporting the neck as desired.

On the other hand, down are used as filling material for down duvets ensuring opti-mum thermal insulation and rapid decrease in humidity (climate of the bed hollow). Thereby, down are pleasantly light and very resilient.


However, there is one important thing to consider: Duvets and pillows should be fluffed up in the morning to retain their shape for a long time
