Terms of Reference

There are a lot of terms on our website with which you may be unfamiliar as they are seldom used outside the bedding industry. We try to define these terms as they arise in our articles and duvet guide, but, for your reference, here is a brief glossary of terms related to duvets and down.

CUIN

CUIN stands for Cubic Inches Per Ounce. It is one way to measure the fill power of down.

Down Cambric

A down-proof fabric (one which keeps the down inside) that can serve as ticking for a duvet. Cambric fabrics are light and closely woven.

Down Classes

Down is divided into classes signifying its quality and, therefore, its suitability for being used in a duvet. At Downduvet.co.uk, all of our duvets are filled with the very best, Class I down. Our duvets are all either 100% down or down with a maximum of 10% feathers.

Eiderdown

Eiderdown is gathered by hand from eider duck nests at the end of the breeding season. Eider ducks live around the northern coasts of Europe, North America, and Eastern Siberia. Their breeding area spreads from the Arctic Circle, down to more clement zones such as Scandinavia, Scotland, Denmark, Iceland, and Eastern Greenland. Eiderdown is the most exclusive and sought after variety of down.

Fill Power

Fill power is a measure of a down’s elasticity, indicating how well it retains air and its efficiency as an insulator. The higher the fill power, the less weight in down you will need to keep warm.

Mako Cambric

Mako cambric is a woven fabric made of Egyptian Mako cotton. Ticking made of Mako cambric is very light and airy.

Mako Satin

Mako satin is a fabric made of Egyptian Mako cotton and is woven with satin thread. This makes one side of the fabric (the outside of the ticking) exceptionally smooth.

Ne Value

We use a fixed-weight system to determine the quality of the ticking. The Ne (Number English or cotton count) value of a woven fabric indicates the delicacy of the thread. The yarn becomes finer as the count number increases. A fabric with an Ne value of 1 would use one pound of yarn if it were extended to 840 yards in length.

Seaming

To ensure that no down escapes from the edge of the duvet, the ticking must be properly sealed. A decorative matt edging, a shiny decorative edging, or an elegant double seam can be used to accomplish this.

Ticking

The ticking or cover of a duvet is the fabric which encases the down. Ticking must be down-proof so as to prevent down from leaking out. Ticking on a good down duvet is made mostly of woven cotton.
