Although acrylic warms almost as well as wool, it is far more flammable.
Autumn is just around the corner, although many places are still summer on the league. It therefore approaches the time to creep down on the couch with a cup of hot drink and maybe even with a blanket over you, which can actually help you turn down the temperature to one degree and save some power.
We have tested four different blankets; one in acrylic, one in polyester, a cheap woolen blanket and an expensive woolen blanket. The two best kept on the heat and therefore should be assumed to be the blankets that give the best warming effect were the woolen plaids. Perhaps not surprising all the while wool in most contexts is highlighted as the best substance to wear.
Wool stays warm
– Wool has proved to be the best to keep warm. Even when it’s damp, wool creates heat, unlike cotton that pulls the heat out of your body when it’s damp, researcher at the Norwegian Institute for Consumer Research, Ingun Klepp, says to clicks. no.
She also emphasizes that fire safety is an issue that should be considered when buying a blanket.
Acrylic and wool are almost as good
We tested the insulation capability of the four blankets as follows: We cooked 3 liters of water, then we put the pot on the table and then put the blankets over individually.
Finally, we measured the temperature in the water after 45 minutes. We noticed that there had also been a certain evaporation that had been deposited as moisture on the blankets.

In no way do we consider this test to be scientifically durable, but it gives a hint.
Highest temperature indicated the least emission of heat energy, which in turn gives an indication of the plinth’s insulating ability.
Our test shows that wool is best kept on the heat, closely followed by acrylic.

Thanks to Princess Oslo City (cheap) and Polarhem PR (expensive) for lending wool blankets.
Ingun Klepp is no surprise that wool in our test was best kept on the heat.
Do you see what’s wrong?
– You know that even when wool is moist it will produce heat.
It is a property called heat sorption (sc. : Heat of Sorption). The starting point is that wool has hydrophilic properties, which means that it is attached to moisture. In addition to the fact that wool can absorb large volumes of moisture, the process also leads to the development of heat.
– We know that wool has the ability to absorb 30 percent water before it feels damp, says Øyvind Myhr, general manager of Hillesvåg Ullvarefabrikk.
– For example, cotton feels damp when the laundry becomes wet.
Both of these properties, the ability of the wool to absorb moisture and heat production when it is damp, according to Klepp, causes wool to feel warm.
– In addition to these properties, the thickness also has a bearing on the ability of the blanket to hold on to heat. In general, wool has most of the qualities we need in a blanket. It is also a substance that stays clean longer than other fabrics, and therefore it is more easy-to-use. It also fires with more dignity, so it stays nice and cozy anymore. The choice of wool is therefore about both environment and aesthetics.
– Would keep me far away from acrylic
The pledge closest to the wool in the test was acrylic, and according to Myhr it has some of the properties of wool and therefore these substances are sometimes mixed in products.
Ingunn Klepp, however, would have opted for acrylic, among other things because it is flammable.

– This differs from wool, which is difficult to ignite, she expands.
The website of the Directorate for Social Security and Preparedness (DSB) describes acrylic as a substance that burns strongly, melts and drips when it is first ignited.
“Acrylic is the most combustible of the synthetic fibers and should be avoided in clothing used in flammable situations, f. example. by igniting bonfires, barbecues and the like, “they write.
Acrylic, like polyester, is a plastic product and Klepp also believes there is a reason to choose blankets in this fabric.
– We do not need plastic in the environment, so why choose a plastic blanket? Choice of blankets has both environmental and fire hazard.
