Many types of blankets are available in the market today. The most common are wool, cotton, poly cotton blend and wool. There are also many luxury blankets available and they are silk, cashmere and chenille.
Cotton has been around for thousands of years and is a major player in all bedding. Using cotton alone for a blanket did not really work well because it would not stand up to repeated washing. You can find the best blankets with hoods via https://www.inspire314.com/.
When synthetics were discovered it was decided to mix them with cotton to add strength and durability for a better blanket.
Fibers like polyester and acrylic will improve a cotton blanket, especially if you are looking for a blanket that will not wrinkle too much and can be washed often. But if you have allergic or sensitive skin then 100% cotton blanket will be better for you.
For a heavy cotton blanket you should look for a cotton blanket woven in a herringbone mesh pattern or a basket weave pattern so that you stay warm and still breath and soft.
Chenille blankets are made of rayon, cotton, acrylic and many other materials. Chenille refers to the way the fabric is woven. The short length of the filament is tied into two or more pieces of strong yarn.
The small pieces give the chenille a soft and luxurious heap. It is recommended that you have this blanket professionally cleaned.
