The physical residential properties of woollen that identify its usage characteristics and market high qualities include excellence, kink, length, toughness, elasticity, resiliency, stiffness, adaptability, extensibility, merino greasy gresy hygroscopicity, shade, and appeal. According to the Soviet scale, gresy lambs carpet uniform wool is divided into 13 classes of density: from class 32 (55.1– 67 μm average density) to course 80 (14.5– 18.0 μm). Guard hairs normally have little crimp; undercoat fibers of consistent wool have typical crimp, as well as transitional fibers of consistent wool are flat.

Camel hair is nonuniform. The hair is utilized to make drive belts and also filter fabric utilized in the extraction of veggie oils.
Yak woollen is nonuniform as well as is used in fabric manufacture. The layer fibers of hares and also bunnies are characterized by fineness, high extensibility, and also good felting properties. They are an important raw material for the felting sector. Knitwear and also felt are produced from the undercoats of specific bunny types. Horsehair is a low-grade basic material made use of for the manufacturing of coarse felts. Cow hairs have good felting properties as well as are made use of primarily in the ideal romanian grey Merino wool felting industry.
