The dyed film was metallised on the undyed side with aluminium by vacuum vapour deposition. The films were then passed through two five foot long ovens heated to 185 C. at 24 ft/min to effect thermosol fixation of the dyestuff from the coating layer into the polyester film. In a preferred form of construction, the first (dyed) or preferably the second (undyed) surface of the coloured film is laminated to the unmetallised surface of the metallised film. In this embodiment, the surface speed of the gravure roll is preferably higher than the speed of the film, generally in the range 1.25:1 to 2.5:1, preferably 1.5:1 to 2.0:1. SOLUTIA INC., MISSOURI, Owner name: The disperse dyestuff generally penetrates only a relatively small distance into the film in the practice of the process of the invention. A preferred range for the viscosity of the dye mixture is 5 to 50 centipoise. (3) heating said film to cause said dyestuff to migrate from said layer into said film. Coloured polyester film prepared according to the method of the invention may be adhered to glass and suchlike materials, for example in the form of automobile windows or of flat glass such as is used in domestic and office windows.

The viscous dye paste is applied as a layer at least 24 micron thick to the surface of a polyester film using a stainless steel wire-wrapped rod. Under such conditions, the washing liquor may be very lightly coloured or nearly colourless. The ability to use relatively low fixation temperatures is an advantage of the invention. You can give your consent to entire categories or display further information and thus only select certain cookies. The heating step may be carried out for example at 160 C. for 60 seconds or 180 C. for 30 seconds, although higher or lower temperatures and other times can also be used. Alternatively, the film may be washed by passage through cold or warm water white being subjected to ultrasonic vibrations. No. The dye mixtures were coated onto 24 micron thick biaxially oriented polyester film (supplied by Hoechst Diafoil under the Trade Mark Hostaphan 5211) using a gravure printing machine supplied by Inta Roto, Richmond, Va. Samples of the treated film were then coated and heated a second time under the same conditions. The coated wet layer is typically a few micron thick, for example 1 to 10 micron thick. The viscosity of the dye mixture is measured under low shear conditions, for example in an Ostwald viscometer, Brookfield viscometer or Zahn cup.

The wash liquors contained a small amount of unfixed dye. This makes them ideal for label applications requiring precise registration and dimensional control.

The Quality Index of the dried coating was assessed to be 1. Wir verwenden Cookies und andere Technologien auf unserer Website. No thickener was added in this Example. It is an advantage of the present invention that dye mixtures for use in the invention may readily be prepared from disperse dyestuffs in powder form because the low-viscosity dye mixture used in the invention is easily mixed to form a homogeneous blend. The aqueous dispersion contains 1-4% dye, 0.1% sodium alginate and 0.003% of a sodium aryl sulfonate wetting agent. Save The former of these techniques is the one more commonly used. The gravure cylinder was driven in the opposite direction to the film web, but not necessarily at the same speed. The dye mixture may be coated onto the film at ambient temperature. Wir verwenden Cookies und andere Technologien auf unserer Website. It is an advantage of the present invention that no swelling agent need be present in the dye mixture.
A dye paste consists of a disperse dye (for example C. I. Disperse Red 60), 2.5-8% of a high molecular weight thickener (for example sodium alginate, sodium carboxymethyl starch, or hydroxylated guar gum), and water. In another embodiment of the invention, the film passes between the reverse gravure roll and two yoke rollers which serve to hold the film in light contact with the gravure roll. The maximum total solids content of the dye mixture by weight may be up to about 25% and is preferably 20%, more preferably 15%, further preferably 10%. COURTAULDS PLC, UNITED KINGDOM, Free format text: It was also found that web and cylinder speeds of 100 ft/min and higher could be used more satisfactorily when the dye mixture contained IPA. The tow is first padded with an aqueous dispersion of the disperse dye and then placed in a conventional raw stock dyeing machine, after which water is circulated through the padded tow at a temperature of 200-300 F. (93-149 C.) to fix the dye on the fibre. This is specified as having a viscosity of 60-90 centipoise measured on a 1% aqueous solution at 25 C. using an Ostwald viscometer. Disperse Blue 60 liquid dyestuff, 88.6 parts by weight of a thickener which was an 1% aqueous solution of CMC and 20 parts by weight IPA. 1 part Dispersol Blue C-3R and 99 parts water were mixed to produce a dye mixture having a viscosity close to that of water (1 centipoise).

Preparation of a conventional dye paste having a viscosity of 2000 centipoise or above from disperse dyestuff in powder form may require the use of special mixing apparatus or techniques in order to obtain a homogeneous blend. It was unexpected to find that an aqueous suspension of dyestuff exhibiting a low viscosity could successfully be coated onto a hydrophobic polyester film in a gravure printing process to form a uniform coating. The solids in the dye mixture comprise the disperse dyestuff and the thickener. This effect was less in those trials where the dye mixture contained IPA. Google cookie for website analytics. The dye is brought into contact with the film which is then heated to cause migration of the dye into the film. Legal notice. The dyed film was intensely coloured and its Quality Index was assessed to be 10. The colour of film dyed according to the method of the invention is highly uniform along the length of the film. The BRY mix used in some of the trials consisted of dyes B and R together with C.I. A stock solution of thickener was made by dissolving 2 parts SCMC in 98 parts water. 3,958,934 describes a process in which an organic disperse dye is first applied by conventional means to a synthetic polymer, which may be a polyester film, by spraying, padding or printing, and the dye-treated polymer, optionally dried, is then passed through a fluorocarbon fluid at a temperature greater than the glass transition temperature of the polymer.
