Quiz 6: Wool and Mohair

Biology

The fibers are made up of keratin, which grows from skin of an animal and they are used for protection of animal skin from abrasions and also keep the body temperature of animal in a stable manner. These fibers have economical values, because they are used for making of several fabrics that are suitable for the usage of humans. Animal's that have hair as a converging on the body includes pigs, cattle's, pigs, horses and dairy goats. Animal's that have fur as a converging on the body includes non-angora rabbits and mink. The mohair is present on the skin of angora goats and the sheep's have Wool.

The structure of a wool fiber is that it grows from a follicle on the skin that is located on the outer layers of the skin. The follicle base has blood vessels that supply nutrients for the growth of the fiber. It has cuticle as an outer thin layer, and the cortex that backdrops inner core namely medulla. The arrector pilli muscles support the wool fiber and it also has sebaceous gland with wax cells and a sweat gland. Some wool fibers have waves called crimps, which are formed due to differences in the cortex.

Some wool fibers have waves called crimps, which are formed due to differences in the cortex. The mohair fibers have three follicles and they develop groups. Initially the primary follicles will develop and then the development of secondary follicles takes place. Mohair fibers have very less crimps when compared to the wool. The cortex of wool has both para and ortho cells, whereas mohair cortex has only ortho cells. The mohair has specialized scale structures, but wool do not possess these scale structures.
