1 QOAPS and oils are very largely used in the manufacture
t ^ of textile fabrics from cotton, wool, silk, and other fibrous
materials, and in the arts of dyeing and printing those fabrics.
T It has been thought, therefore, that a small handbook which
J would describe the preparation, properties, uses, and analyses
'i of these useful substances would be of use to every person
i concerned in their preparation and use ; hence the appearance
V of this little book. In writing it, the author has kept in view
V^ the practical side of the subject, and tried to gather together
k that information which would be of most value in the practical
X application of the soaps and oils.
'^ Those readers who may desire further information regarding
^ the materials and methods of manufacture are referred to the
author's large book on Soaps. As regards oil, there is one use
of these bodies in the textile trades which is not referred to
here, and that is in the lubrication of the machinery. This
1 subject will be found dealt with in the author's book on
\ ^Lubricating Oils, Fats, and Greases.
