    Abstract: A pair of stretching pulleys are rotatably mounted on a pair of support plates within a housing. A belt is wound around the upper part of the stretching pulley and a number of turn pulleys. A film introduced onto the stretching pulley is held between the belt and the stretching pulley and is transferred. Air flow generated by a fan and heated with a heater is blown against the film through a louver and circulates through bellows mounted to the housing to return to the fan. The stretching pulley is partially cooled in a water bath. The support plates are rotatably connected to screw shafts, thereby changing a distance and angle between the plates. The stretch width or stretch ratio of the film is thus adjusted with the change of the distance and angle.

    Abstract: Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric. The sprayed fabric is held under transverse tension in a heated (350.degree. to 450.degree.

Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.

  • Patent number: 4448582
    Abstract: A textile fabric formed of synthetic fibrous material or blends with natural fibers to which dyestuffs have been applied is subjected to a thermosol heat treatment by directing the fabric supported on an air permeable conveyor through a heated oven while directing heated air downwardly through the fabric and through the underlying supporting conveyor and while at predetermined longitudinally spaced locations as the fabric travels through the oven directing heated air upwardly through the open mesh conveyor and into contact with the fabric so as to lift portions of the fabric from the conveyor to permit free shrinkage and bulking of the fabric while avoiding distortion of the fabric or obtaining an undesirable ironed surface appearance as would occur if the fabric were pinned to the conveyor. This method also achieves very rapid and efficient heat transfer to the fabric and thus avoids the extreme time and temperature conditions which result in harsh treatment of the fabric.
