It can survive in moderate alkaline conditions but is adversely affected by acids. Cotton does not transmit moisture like linen and is very absorbent in its processed state. It is this characteristic which allows cotton to take dyes well. Figure 8.2 . Schematic drawing of cotton.
Wool consists of protein fibers.
The majority of the amino acids in the protein of the wool are keratin, which contains insect-attracting sulfur. Wool fibers absorb more moisture and accept dyes better than vegetable fibers. Wool is not a strong fiber and weakens considerably when wet. Figure 8.3 . Schematic drawing of wool.
