8 MR. TOPPAN'S NEW PROCESS 



When a sufficient number of scours have been made by the 

 Toppan process, the average of these will be comparable with 

 the figures now known with reference to the present Systems. 

 But if I cannot quote figures of my own, I have fortunately a 

 series of experiments which are as reliable as anything can be 

 expected to be under the circumstances. 



Last year the Manufacturers'' Review and Inditstrial Record 

 of New York undertook a series of experiments which were 

 conducted by their own men and, as they claim in their Jour- 

 nal, for their own information only. 



In Order that an authoritative Statement might be made to 

 the trade, a series of tests and experiments was decided upon 

 and Mr. W. B. Guild, the manager of their New England 

 agency, was given entire charge of proceedings, with füll 

 authority to employ a dyer of his own selection to make any 

 tests desired. The experiments were made for convenience 

 at Canton and occupied several days. The utmost accuracy 

 was maintained in the observations, and the weighing was 

 doneby Mr. Guild himself. 



The results of these experiments I give in the words of 

 the report as published in the Record : — 



" The first test was taking 4|- oz. of Texas fleece which was 

 estimated to give a very heavy percentage of shrink. This was 

 placed in the scour liquor at 120 deg. F. for five minutes, and 

 then passed through an S liquor ab.out one and a half to 

 two minutes. There resulted from this 2\\ oz. of extremely 

 clean, white, and handsome wool." 



The loss in weight in the specimen, through shrinkage, was 

 38 J per Cent. 



The other experiments are thus described, one of them 

 being with a yellow bück fleece : — 



" The yellow bück fleece was obtained for the purpose of 

 getting the worst to scour that could be found. It was what 

 is called a regulär 'yellow bottom,' completely saturated 

 with grease. The tags were very badly matted, and in order 

 to get this fleece approximately clean and free from grease, 

 with tags duly cleansed, etc., it required, by the old soda pro- 

 cess, from twenty to thirty minutes, and even at that time the 

 wool, though passably clean, was far from white or handsome. 

 The average percentage of clean wool resulting from a num- 

 ber bf trials by the soda process, made as fairly as possible, 

 was 30^ per cent clean wool. 



"By the Toppan process, the same wool was scoured 

 perfectly dean^ at a temperature of about 123°, in time from 

 two and a half to five minutes. This, when put through the 

 S water (which worked as well, either warm or cold) for
