Laboratory Manual of Dyeing and Textile Chemistry Book

LABORATORY MANUAL DYEING AND TEXTILE CHEMISTRY -- 1909 -- PREFACE. -- THIS volume is designed with the purpose of meeting the demand for a text-book on the subject of textile dyeing and chemistry. The method of presentation and the subject matter herein contained have been the outcome of a number of years of teaching on the part of the author. Care has been taken to avoid a too purely scientific generalization, else as a text-book it would lose its main value. The subject treated is a technical one, and an endeavor has been made to present it in a technical manner that is to say, definite facts have been presented in a definite form. For this purpose, the experimental method has been adopted, further elucidation being given in additional notes as succinctly expressed as possible. The insertion of quiz questions has also been carried out in order to stir up the thought of the student after he has performed the manual experiment. This book is intended as an elementary manual for the students who are primarily to be found in the various textile schools and in institutions where the many branches of technical chemistry are taught. It is hoped that it will be of some value to both the student and the teacher interested in this Iine of instruction. It is primarily a laboratory manual or guide, and is intended to direct and supplement the lectures of the teacher, and should be used in conjunction with the more general treatises on the subject. The subject matter is divided in such a manner as to provide a course of instruction for one complete college year, each section corresponding to a weekly apportionment of study. The experimental part will require from eight to twelve hours df laboratory practice each week though sufficient experiments have been given to allow the teacher considerable latitude as far as selection of material and length of laboratory practice are concerned.
