An example of the desirable quaIities that can be given to fabrics in the finishing
process. Some fabrics are treated with colorless chemicals, similar to dyestuffs, added to the dye bath. Another method atomizes the fabric with mothproofing chemicals. Fabrics that attract moths, such as woolens, can be treated for repellency. The treatment also repels other insects, such as carpet beetles. Wool rugs are almost always treated for moth repellency today.
