PREFACE.
In writing this little book the author believes he is supplying a want
which most Students and Dyers of Cotton Fabrics have felt--that of a
small handbook clearly describing the various processes and operations
of the great industry of dyeing Cotton.
The aim has not been to produce a very elaborate treatise but rather a
book of a convenient size, and in order to do so it has been necessary to
be brief and to omit many matters that would rightfully find a place in a
larger treatise, but the author hopes that nothing of importance has been
omitted. The most modern processes have been described in some
detail; care has been taken to select those which experience shows to be
thoroughly reliable and to give good results.

CHAPTER I.
STRUCTURE AND CHEMISTRY OF THE COTTON FIBRE.
There is scarcely any subject of so much importance to the bleacher,
textile colourist or textile manufacturer as the structure and chemistry
of the cotton fibre with which he has to deal. By the term chemistry we
mean not only the composition of the fibre substance itself, but also the
reactions it is capable of undergoing
