Pine-leaf Fab′ric.
This is described in the “Journal of the Franklin Institute,” 1852, page 412 et seq. The green leaves are used in preference at Breslau for making this pine-tree wool, which was extensively used from 1842 for mattresses, coverlets, etc. Five hundred of these coverlets were purchased for the hospital of Vienna in the former year, and shortly afterward at other places. It was particularly useful as stuffing for beds and for upholstering, as it was offensive to insect vermin. The leaves are treated by heat and chemical reagents to separate the fibers and remove the resin. The invention is credited to M. Pannewitz. “Bib. Univ. De Genevi,” June, 1852, page 165. See also English patent, No. 1002, 1853. See also Belgian patent, “Genie Industriel,” Paris, 1864, page 104, where the process is fully described. |
