Kamptulicon (Kamp-Tu'-Li-Con). A variety of floor cloth, invented in 1843, but not generally introduced until about 1855. The materials and processes employed in its manufacture vary considerably, but it is essentially a preparation of india-rubber masticated up with ground cork, the preparation and mixture being effected by repeated passing of the material between heavy grooved metal rollers. When thoroughly mixed it is rolled out into sheets; sometimes over a backing of canvas by passing it between pairs of wide and steam-heated rollers. In addition to the substances above mentioned, gutta-percha, saw-dust, ground leather, boiled oil, resins, pitch, asphalt, and chalk have all been used in kamptulicon making. The rolled sheets are ornamented by printing simple patterns on their surface. Kamptulicon forms a warm, pleasant, soft and noiseless floor-cloth, but the higher qualities, in which india-rubber and ground cork are the main ingredients, are rather expensive, and the manufacture has been curtailed since the introduction of linoleum.
