摘要

PICT:0441660/IV/1 PICT:0441660/IV/2 Apparatus for dyeing piece goods made from animal, vegetable or artificial fibres, particularly closely woven or felted material, at atmospheric pressure, comprises a dye tank or bath through which the fabric is passed, in endless form C, as shown, or as a continuous length. One or more series of pipes D, D1 are fixed in staggered arrangement relative to the line of feed of the fabric C between them, and situated at a distance not more than six inches from the fabric. Air or steam or a mixture of both is admitted to the dye bath V through perforations in the pipes to set up a turbulence of the dye liquor in the vicinity of the fabric and a difference of pressure of dye liquor on the two sides of the fabric. The axes of the perforations in the pipes D, D1 are not in the same plane. Specifications 14871/89, 11254/06, [both in Class 15], 207,211, 327,168, [both in Class 15 (i)], 356,860, 386,520, and 436,875 are referred to.
