If the Dyestuffs Act is put in operation so as to exclude the competition of foreign chemicals, it not only keeps our chemists in ignorance of the developments of the industry abroad: it raises the prices of dyestuffs against the dye-using industries at home, and thereby handicaps them dangerously in their never-ending competition with the foreign industries, German and other, which offer the same goods in foreign markets.
He talked about the future of British Dyes now that Germany was out of the race, and . . . well, the long and short of it was that I took his advice and bought on margin. Bought like the devil. And this morning Amalgamated Dyestuffs went all to blazes. There you have the whole story!" "And now," said Jill, "comes the sequel!" "The sequel?" said Uncle Chris breezily. "Happiness, my dear, happiness!
Mineral and Pigment Dyestuffs. These colours are insoluble in water and alcohol. They are either fixed on the fibre by mechanical means or by precipitation. For example, you use blacklead or plumbago to colour or darken your hats, and you work on this pigment colour by mechanical means. I will show you by experiment how to fix a coloured insoluble pigment in the fibre.
Dyestuffs include, by definition, all the coal-tar dyes, colours, and colouring matter, and all organic intermediate products used in the manufacture of these the last category including a large number of chemicals such as formaldehyde, formic acid, acetic acid, and methyl alcohol.
When he regained consciousness, he was lying on a thick, dusty mattress, his head pillowed on a bundle of cloth that smelled of cotton and dyestuffs. Faces emerged from the gloom around him. Some one was holding a torch over his strange couch. That odd face in bismuth and lampblack was bending over him. "He's come 'round, Mrs. Braddock," he heard this creature say, in a far-off voice.
He knew things about glassmaking, enamel-work, dyestuffs, and medicine, that no one else did. He was occupied almost wholly with experiment and research. There are not two such men in a century. "Giovanni, you are the only one of us who has been beyond the Rhine. Do you know any one there who might possibly aid in this search?" The Lombard seldom talked unless he was directly addressed.
The necessity, for example, of encouraging the manufacture of dyestuffs and related chemicals; the importance of doing everything possible to promote agricultural production along economic lines, to improve agricultural marketing, and to make rural life more attractive and healthful; the need for a law regulating cold storage in such a way as to limit the time during which goods may be kept in storage, prescribing the method of disposing of them if kept beyond the permitted period, and requiring goods released from storage in all cases to bear the date of their receipt.
By passing the dyed cotton through water acidulated with a little vitriol or alum, a redder tint is assumed. DYESTUFFS AND COLOURS Continued Artificial Substantive Dyestuffs.
The original pigment say blue or blue-black ink is placed in the ink, to make the writing visible at first, and gradually fades, giving place to the black of the tannate which is formed. The dyestuffs employed in the commercial inks of to-day vary in colour from pale greenish blue to indigo and deep violet.
The dyestuff industry had been developed to such a point in Germany that Germany supplied the whole world. In the first months of the war some enterprising Americans, headed by Herman Metz, chartered a boat, called TheMatanzas, and sent it to Rotterdam where it was loaded with a cargo of German dyestuffs. Th boat sailed under the American flag and was not interfered with by the English.
