SLEEP AND COMFORT
A healthy person sleeps a third of his life. And, of course, person wants to spend this time in comfortable conditions. And, no matter how trivial it sounds, they can be provided only by quality bedclothes. After all, even the pillows and blanketshave not bypassed the scientific and technological progress — the stores present products using the latest technological developments.
Where to lay your head
The cost of the pillows is influenced primarily by the composition of the filler, the quality of the cover and the size. In many bedclothes models special antibacterial textiles are used, which significantly slow down the growth of fungi and microorganisms. They provide hygroscopicity of products and are recommended primarily to allergy-predisposed people and people with diaphoresis.
In the assortment of each store there must be products with such cases.
As filler for pillows, goose or duck down is usually used with the addition of a fine feather. Half-down goods (down content less than 50%) are less soft and wear-resistant, however, the price is lower than that of down products.
To test the filling power, one ounce of down is compressed with a pre-determined weight. When the weight is removed, the down expands and the volume of space it occupies is measured in cubic inches.
Then it is normally just stated as the number, followed by the words «fill power». For example, a goose down filling that occupies 700 cubic inches of space per ounce, would be listed as 700 fill power!
A comforter with a high fill power doesn’t have to physically weigh as much as one with a lower fill power to be just as warm because the insulating power is increased as the fill power increases! You will remain extremely comfortable all throughout the night when you use down comforters that have high fill power.
Turbidity is a test to see how transparent the rinse water is when you are finished washing the down and feathers. Turbidity is, in fact, the true overall level of cleanliness of the down material as it determines the amount of dust and dirt that remain in feather and down products!
To perform this test, a sample of down is put in a container of distilled water and vigorously agitated for 20 minutes minimum with a mechanical shaking device. The sample water is then poured into a graduated tube that is 1,000mm high. This tube has a crosshair site at the bottom of it. When you pour the water into the tube, you must be able to just see the crosshair in the bottom.
Naturally, the higher the level of water is, while still seeing the cross-hair site, the cleaner the down is! When the water comes to a level where the crosshair will just go out of sight, you stop pouring the water into the tube and take a reading of its height.
The Oxygen Number : The Oxygen Number is a well know test for determining the cleanliness of the down and feather material. This test is a little more scientific to perform, but works just like the turbidity test.
The oxygen count test determines the amount of foreign organic matter on the surface of the down and feathers. To qualify as “clean” the oxygen number must be less than 10. The test is actually determining the chemical decomposition of the down filling material.
The maximum North American industry standard is 10mg/100g sample of down.
Amount of down: First of all, there is no such thing as «100% Down» or «Pure Down» for any kind of down on the market — no matter what anybody tries to tell you! Down content is measured as «Net» Down Clusters.
By law, a product can be described on the label as «Down» or «Goose Down» when it has 75% net down clusters or more in it.
