About This Book

This work provides a comprehensive examination of the principles and processes involved in paper-making, emphasizing the scientific understanding necessary for effective practice. It covers the chemical properties of cellulose, the physical structure of fibers, and the analysis of plant substances, detailing methods for isolating cellulose from various raw materials. The text discusses specialized treatments for different fibers, bleaching, and the mechanical processes involved in paper production. Additionally, it addresses the testing and quality control of paper, along with considerations for site selection and water purification in paper mills. The authors aim to enhance the reader's grasp of the scientific foundations essential for modern paper-making.

CHAPTER XVII. STATISTICS.

Raw Materials.

The statistics concerning the trade in raw materials for paper-making are not published in a detailed form, all the various kinds of fibre, &c., being grouped under two heads, viz. rags (linen and cotton), and esparto (which embraces other fibres, and probably wood pulps). The figures for recent years are shown in the accompanying tables:—

(a) Imports of cotton and linen rags:
tons. l.
1880. 29,642 451,782
1881. 26,773 396,274
1882. 21,200 303,349
1883. 28,543 401,922
1884. 36,233 487,866
1885. 35,470 466,928
(b) Esparto and other material:
tons. l.
1880. 228,580 1,642,903
1881. 238,043 1,626,800
1882. 251,594 1,784,078
1883. 288,549 1,943,732
1884. 260,544 1,638,564

But a portion of these imports was exported again, the figures being as follows:—

(a) Exports of rags and other paper-making material produced in the United Kingdom:
tons. l.
1880. 55,792 673,523
1881. 50,488 563,460
1882. 49,352 526,554
1883. 51,293 502,851
1884. 60,924 562,903
(b) Exports of ditto of foreign and colonial produce:
 
tons. l.
1880.  6,965 102,499
1881. 10,183 146,101
1882.  7,004  84,515
1883. 11,561 121,992
1884. 26,498 274,664

A considerable export of raw material for paper-making also takes place from British shores, the figures, embracing rags and other materials, for 1884 being as below:—

Our imports of “rags and other paper-making materials” from Norway increased from 23,483 tons, value 138,098l., in 1880, to 48,199 tons, 279,679l., in 1884, mainly owing to the development of the wood-pulp industry. Later figures will probably show a similar increment. The same articles from Denmark grew from 359 tons, 3406l., in 1880, to 1403 tons, 16,352l., from the same cause. German statistics have even a stronger upward tendency: 11,587 tons, 196,051l., in 1880, against 196,051 tons, 331,591l., in 1884. Our receipts of esparto from Algeria show an advance, but not a marked one, being 60,612 tons, 421,343l., in 1880, and 88,357 tons, 515,232l., in 1884. But shipments of the same fibre from Spain show a decline from 51,413 tons, 454,713l., in 1880, to 40,159 tons, 314,927l., in 1884; and from Morocco they have fallen away from 2879 tons, 18,231l., in 1880, to 260 tons, 1290l., in 1884; while the figures relating to Tunis and Tripoli also show a disposition to recede, though not at such a rapid rate.

The wood-pulp industry of Norway for the year 1886 shows a very large increase upon the figures of a few years back, albeit prices have ruled very low. This latter circumstance is attributed, not so much to over-production, as to excessive competition among the sellers of this article. The quantity exported during the year 1886 is about 120,000 tons; in the year 1885 it was 107,651 tons; 1884, 88,220 tons; 1883, 70,464 tons; 1882, 58,884 tons; 1881, 42,194 tons; 1880, 26,055 tons. Several of the old works have extended their production during the past year, and several new establishments are in the course of erection, so the production this year may probably be put at 150,000 tons wood pulp with 50 per cent. water. The greatest part of the Norwegian wood pulp is exported to England, France, and Belgium; in Russia, the increase in the duty has stopped business, and the same can almost be said of Germany. America, too, has drawn part of her supply from Norway, but this trade is not expected to continue. {225}
