<p>Liquid dye deposited on the pile (18) of a carpet tile can be fixed by inserting an array of heated pins (11) into the pile. The pins, mounted on a block (12), penetrate the tufts of the pile which have liquid dye thereon, but do not penetrate the backing of the carpet tile. A heating element (13), to raise the pins to the fixation temperature of from 90°C to 100°C, is clamped to or located within the block. Preferably, both the block and the pins are made of metal (not necessarily the same metal). This equipment can be used to heat other penetrable media. Replacement of the heating element with a cooling element enables similar equipment to be used to cool a penetrable medium.</p> |
