Abstract
A process and apparatus for making the appearance of a raised fabric suede-like comprising jet spraying a high pressure liquid (12) (14) onto the nap surface of a raised fabric through the means of the liquid passable material (2) having liquid impassable parts thereon while keeping the reverse side of the raised fabric (26) in close contact with the supporter (16) whose surface has a pattern of random contour variation specified by raised parts and hollow parts, in order to make the appearance of the raised fabric, which has the nap composed of extra fine fibers of monofilament fineness in the range of 0.0001 to 0.8 denier, suede-like.
Claims1
An apparatus for preparing a suede-like raised fabric comprising a rotatable cylindrical fabric supporter having an imperforate surface with a pattern of random contour variations thereon for supporting a travelling length of said fabric on a portion of the surface thereof, a hollow rotatable cylinder disposed in parallel spaced relation to said fabric supporter and having a liquid passable perforate surface comprised of a 5-300 mesh wire gauze whose meshes are partially and randomly closed so as to provide an open surface area constituting 10-80% of the total surface area, jet nozzles disposed inside said hollow rotatable cylinder with the nozzles directed toward said fabric supporter for randomly directing jets of liquid through said wire gauze onto the fabric and means for rotating said fabric supporter and said cylinder simultaneously to provide a random surface effect on said fabric.
