Solution:The above statement is true.
Wool is an animal fibre. The different processes involved in wool production are shearing, scouring, grading or sorting, dyeing, drying, and the making of yarn. Sorting or grading is done after scouring. Wool is a textile fibre produced by sheep and other mammals, particularly goats, rabbits, and camelids. Inorganic materials with properties similar to animal wool, such as mineral wool and glass wool, may also be referred to by the term.
