Dyes from Camphor.

Manufacturer and builder 4, 1880

Dr. W. H. Gregg, of Elmira, N. Y., is reported to have succeeded in obtaining a new coloring principle from camphor, to which he gives the name of "Laureline." Thus far he has only succeeded in producing various shades of yellow from it; but he is reported to be engaged in certain experiments which he hopes will result in the production of carmine and scarlet. The chief feature of the new dyestuff which recommends it to the attention of textile manufacturers, is in the brilliancy and fastness of the colors.

It can be used upon linen, cotton and silk with no apparent difference in density and brilliancy, and goods thus dyed are said to be entirely unaffected by the ordinary tests to which they will be subjected in use. Boiling for hours in a strong soap solution barely turned the shade of a cotton sample. With indigo, a handsome green is produced.

The inventor is not yet prepared to give special details respecting the cost of producing the new dye, or of the precise methods of using it; but as regards the first item, he intimates that it will be one of the cheapest, and as to the second, one of the simplest coloring matters to make and apply. The textile journals speak in terms of great interest of the new discovery.
