The process of quality control starts when the materials arrive. The felt is checked for its weight and quality particularly. Some of the companies purchase wool which has been baled and scoured, the originality of the bales is tested when it gets in.
Originally hats which were made from felt were produced by using animal fur, mostly beaver fur. The fur was combined with other fiber like wool by adding pressure, moisture and heat. At that time the best hats were made of beaver skin and many a time’s the men’s hats were referred as beavers. These hats had become very famous in the middle ages. But by the end of fourteenth century the cost of the beaver hats came down and was mostly produced in Low Countries.
Felt can be called as the oldest fabric known to man and to prove this there are many ancient writings on felt. As felt does not need to be produced by loom and is not even woven, it was easy for the ancient man to make it. Some of the remains of felt products were discovered in the tombs of horsemen of ‘Siberian Tlai Mountains’ in 700 BC. The tribes of nomadic horsemen made saddles, tents and clothes from felt material because it had high resistance against snowy and wet weather.
