Excerpt: ... From this list it will be observed that the Fiji and Tahiti Sea Island cottons are the most irregular in the length of their fibres, the extreme variation in both being half an inch. Now, as long and short cotton never incorporate well together, nor is adapted to the production of a regular yarn in appearance and strength, it is easy to understand that they are relatively wasteful cottons to work. In any spinning mill where they are used, it will be found that the quantity of fly, combings, and flat waste made at the various machines is very great, and the reason of this is that, in any cotton where the fibres are of different lengths, the long and strong will have a tendency to throw out the short and weak. Next in order of irregularity comes respectively the Florida Sea Island, Peruvian Sea Island, and Gallini Egyptian--the two former showing a variation of three-eighths, and the latter five-sixteenths of an inch; while the cotton which presents the greatest regularity is the Orleans, with a variation of only three-sixteenths of an inch. As regards the diameter, it will be observed that the cottons with the longest fibres are, as a general rule, also the finest; so that of two yarns of equal hank, but from different classes of cotton, that produced from the finest fibre will be more compact, solid, and cylindric than the other. Our microscopic illustration, Fig. 31, exhibits the thread of two different classes of yarn as taken from the cops--A being spun from white Egyptian and B from brown Egyptian cotton; the fibres of the former having a mean diameter of Tveuth in., and the latter TA nth part Fig. 31.--Showing microscopic illustration of the threads of two different classes of yarn taken from the cop.
