Excerpt from Useful Information for Cotton Manufacturers, Vol. 4 of 4: Compiled and Issued
In the equipping and starting up of so many mills, my interest in the effect of varying humidities has been excited by noting the striking results of changeable atmospheric conditions. All kinds of troubles experienced in the running of machinery that we have furnished, particularly troubles in starting up new machinery, are shifted on to us as "machinery men." Careful study and observation covering a number of years have made it quite clear that the large majority of these troubles is directly traceable to variations in humidity and temperature, from hour to hour and from day to day.
This conclusion was forced upon me even before sufficient data had been collected to prove the point; for -
Why is it, in a mill making the same thing the year through, with the same cotton, the same organization of machinery with reference to speeds, drafts, weights, and other like details, that the work runs differently from day to day, and even that overseers complain that the work does not run equally well on days that appear to be just alike?
And why is it that excessive power consumption, especially of spinning and twisting, occurs in spells of damp weather, and during the early morning hours in all weather, particularly on Monday mornings?
These and many kindred phenomena, some more and some less well known, have been included in the scope of my investigations, the most material and pertinent results of which are:
(1) That the behavior of textile fibers in process of manufacture depends upon the physical condition of each individual fiber.
(2) That the only physical change in the fiber itself not contemplated in the processes of manufacture is that produced by its hygroscopic property.
(3) That the only outside agencies that affect its hygroscopic property are changes of temperature and humidity.(4) That its power of hygroscopically absorbing or losing moisture under varying conditions of humidity and temperature, not only affects its weight, elasticity and strength, but also its dimensions, appearance and even conformation.
Under the present high state of development of textile machinery, and the skill easily obtainable for the proper operation of it, the difficulties properly chargeable in manufacturing to those instruments are quickly hunted down and disposed of.
