This book was released on 2015-07-12 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Pulp and Paper Magazine of Canada, Vol. 13: A Semi-Monthly Magazine to the Science and Practice of the Pulp and Paper Manufacturing Industry With an Up-to-Date Review of Conditions in the Allied Trades; Montreal, January 1, 1916 In order to understand the present situation it will be necessary to know something about the color business before the European war began. In the early days colors used for paper were made from logwood, sumac, indigo, and other vegetable sources. At present, however, our colors are almost altogether manufactured from coal tar. The coal tar industry dates back to 1856, when an English boy, later honored as Sir William Henry Perkins, discovered mauve aniline. Soon after this discovery, the manufacture of aniline colors from coal tar was begun in Germany, and the Germans have continually developed the industry until at present it has reached a very high state of perfection. It might be well to state here that only 6 per cent of the coal tar itself is useful for the manufacture of color. Out of this 6 per cent all of the twelve base colors are manufactured; and from these twelve, through very elaborate and expensive processes, there have been manufactured about 1,200 other shades. In Germany there are twenty-two factories manufacturing dyestuffs, but the larger proportion of the total utput is manufactured by four concerns. These plants are very large; for instance, one of them has in operation 400 steam locomotives, purchases sulphuric acid in tank steamers and employs about 10,000 workmen. These plants are practically under Government control. It is a well-known fact that most of the colors used in this country are of German manufacture. Consequently, when the war started there was much anxiety among color users. Figures show the imports of color to this country to be worth about ten million dollars per year, or 85 per cent of the total value of the colors we use. Having this fact in mind, you can realize how seriously the embargo on color affects the textile and paper manufacturers. At the outbreak of the war, the color manufacturers' agents were swamped with orders from all sources, but they handled the situation very fairly by proportioning the available stock according to the amounts the different companies customarily used. At the present time American color factories are producing a certain amount of paste colors, which is the form used years ago. Blues and reds in the powdered form can be bought, but the colors brown, green and orange have practically been used up, and most of tile mills are finding it necessary to use substitutes. Sap brown, a color which is used in carload lots by the lower grade mills, is no more to be had. An umber is being used for a substitute. Of course, the textile, paper, ink, paint and varnish manufacturers will welcome any relief in the color situation, but it would seem that a new invention in the process of manufacturing color might work out more slowly than would be expected at the start. We all know that the colors we are using to-day are the result of years of expert work by experienced chemists, with Government backing. The results we are able to obtain with the present dyes, which are much better, faster, brighter and easier to handle than previous colors, would make it seem that new companies with new processes might have troubles that would be hard to overcome. - James R.

The strength as represented by Mullen or Schopper tests increases with increasing power con sumption per ton. The relation between horsepower con sumption per ton of pulp per meter of breaking length of paper made from it, and the power consumption in grinding a ton of the pulp is also shown. At low values of power consumption greater strength is produced per horsepower than at high value. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
