Wool fabric milling processes include scouring, fulling, carding, roving, drafting, and spinning. The first step is scouring, which removes dirt, dust, lanolin (a type of wax secreted by the sebaceous glands), and other impurities from wool.The scouring process may be wool activewear fabric conducted using water baths or in a vacuum. Some fabrics are also immersed in a solution of soap and alkaline water or a weak acid.Next, the wool is put through a series of combing steps called carding. These steps comb the fibers several times and help with alignment, uniformity, and softness.The fabric is then placed in a fulling machine. The fabric is passed between stainless steel rollers that are pounded by clappers. The friction from the pounding heats the scales of the wool fibers, which makes them interlock. The fabric is then carefully dried.ApplicationsWool is a natural, renewable resource that is often used for different types of fabrics. It is one of the most versatile fibers available and can be made into everything from light wool gauzes to luxurious wool suitings.There are many different uses for wool and wool products, but most people will probably think of a sheep in the winter when they hear the word “wool.” It’s no wonder that it’s so popular: this natural material is known for its comforting warmth and insulative properties.The crimp and curl in wool helps create air pockets that trap heat and moisture. These characteristics are what make wool a great fabric for warm clothing, hats and gloves.
