PAPER-MAKING. A PRACTICAL HANDBOOK OF THE MANUFACTURE OF PAPER FROM RAGS, ESPARTO, STRAW, AND With a Description of the Machinery and Appliances used TO WHICH ARE ADDED DETAILS OF PROCESSES FOR RECOVERING SODA FROM WASTE LIQUORS BY ALEXANDER WATT AUTHOR OF "THE ART OF SOAP-MAKING,' "LEATHER MANUFACTURE,” “ of Capio Lumen ELECTRO LONDON 7, STATIONERS' HALL COURT, LUDGATE HILL 1890 [All rights reserved] PREFACE. In the present volume, while describing the various operations involved in the manufacture of paper, the Author has endeavoured to render the work serviceable as a book of reference in respect to the processes and improvements which have from time to time been introduced, and many of which have been more or less practically applied either at home or abroad. The recovery of soda from waste liquors has been fully dealt with, and the details of several applied processes explained. Special attention has also been directed to some of the more important methods of producing pulp from wood fibre, since it is highly probable that from this inexhaustible source the paper-maker will ultimately derive much of the cellulose used in his manufacture. Indeed it may be deemed equally probable, when the processes for disintegrating wood fibre, so largely applied in America and on the Continent, become better understood in this country, that their adoption here will become more extensive than has hitherto been the case. |
