Acrylic fibers generally have good hand, as its called in the business (they re soft). They resist creasing, and they are quick to dry. Acrylics have replaced wool in many applications, such as blankets and sweaters. Because of their unique bulking characteristics, they take on the appearance of wool yarn. 

The process for sheepskin is rather more gentle in order to avoid damage to top quiity wool that can be spun into valuable wool yarn. Liquid protease preparations such as pancreatic extracts of trypsin and chymotrypsin are applied to the flesh side of the sheepskin. The proteases diffuse to the basal papilla of the hair follicle, and subsequent protein breakdown releases the wool hair with minimal damage 34),...

By carefully controlled treatments with proteolytic enzymes, it was possible to reduce the buckling load of wool yarns. It was shown that softness is improved and the subjectively perceived prickle of fabrics is reduced. The new yarn-bundle compression test discriminates between wool samples that differ by about 1 pm in mean fibre diameter.
