This document summarizes information about wool, including that it is a protein fiber obtained from sheep and contains natural impurities like dirt, suint, fat, and burrs. It also lists added impurities like dust and grease that get onto wool. The document outlines the preparatory processes wool goes through, including scouring to remove impurities using sodium carbonate or soap, and carbonizing using sulfuric acid to remove any remaining vegetable matter. It provides details on the conditions used for scouring and defines carbonizing.
