Moisture absorbency of quilt filling is very important
Moisture Absorbency - Quilt fillings & Cover Fabrics
Possibly the least understood but an important point about bed quilts.
During the night we all perspire, some more than others, and extensive studies in Europe have discovered that on average a litre of moisture is given off each night. This is normal as it is the way one's body adjusts to its environment, however, it is what happens to this moisture which is really important.
To get an optimal night's sleep, it is essential that you keep dry, hence our mantra 'dry and cool in summer and warm in winter'. It's true!
For a balanced good nights sleep, you need a quilt filled with a naturally moisture absorbent filling material. Alpaca fleece and wool fibre can absorb up to 30% of its weight in moisture.
Bamboo is a cellulostic plant fibre and is exceptionally good at moisture absorbency, both in the amount of moisture it can absorb and how quickly it actually absorbs the moisture.
We are often asked, what happens to the moisture that an alpaca or bamboo quilt absorbs moisture during the night? Well, it's simple, the moisture evaporates during the day when it is warmer. On the other hand, if a quilt is filled with a material that does not absorb moisture i.e. it is hydrophobic, such as polyester, it will allow moisture to build up and will cause temperature variations. The result is usually a poor quality sleep with regular temperature changes i.e. a hot and sweaty night sleep. Not desirable nor good!
It is also important that a quilt cover fabric is absorbent, which is why they are usually made from cotton. Cotton is absorbent, although not as absorbent as bamboo, so it assists in this 'wicking effect' which bedding manufacturers refer to.
