The material is impregnated with a water-soluble high-boiling organic liquid, for example a polyhydroxy compound, preferably diethylene glycol, by heating at a temperature in excess of 120 C. or 175 C. The treated material is more rapidly dyed by disperse dyestuffs than untreated material is. Cookie-Details Polyester film was coated with this dye mixture using the same conditions as in Comparative Example 1. A disperse dye may be defined generally as a substantially water-insoluble dye having substantivity for one or more hydrophobic polymers such as polyesters, for example poly(ethylene terephthalate). 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. kilogram approx 08/643,063, filed Apr. Many of the known swelling agents have undesirable toxicological or environmental properties. The dye bath becomes exhausted of its components as the roll of film is unwound and passed through it. The quality of the dyed film (uniformity, in particular freedom from streakiness) was assessed visually by comparison of different samples of film and is quoted as a Quality Index on a scale of 1 (very poor) to 10 (flawless). The dye mixture preferably contains essentially no particles larger than 50 micron in size, more preferably 20 micron, further preferably 10 micron.
metallized metalized holograms lamination twist It has surprisingly been found that more perfect films having fewer defects can be prepared by the method of the invention than by gravure printing according to the prior art using a high-viscosity dye paste. 3d film polyester packaging rolls transparent type indiamart The wash liquors contained a commercially unacceptable large amount of dyestuff which had not migrated into the film. The dried film was then further heated at 190 C. for 100 sec to cause the dyestuffs to migrate into the film. 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. The thickener has a low molecular weight and accordingly a low solution viscosity in water. The film may contain a substance which absorbs the harmful wavelengths of light, for example an ultraviolet absorber. Weitere Informationen ber die Verwendung Ihrer Daten finden Sie in unserer.

Polyester film was dyed to a charcoal shade of 35% transmission either by a solvent-assisted technique (ethylene glycol) according to the prior art or by the method of the invention. The colours can help to differentiate between different products of release liners or to fulfill different manufacturing specifications.
It was found that, contrary to expectations, increasing the cylinder speed relative to the web speed caused a decrease in coating quality. 
pet metallized film polyester colored larger The coated film was heated to dry the coating layer so formed. This is a continuation of U.S. patent application Ser. metallized ec21 The film was air-dried, heated at 165 C. for times between 30 seconds and 2 minutes to cause migration of the dyestuff into the film, and washed with water. Another known method of dyeing a polyester film with a disperse dye relies upon thermal diffusion of the dye into the film. The wash liquor contained a small amount of unfixed dye. The stock solution exhibited a viscosity of 2000 centipoise. U.S. Pat. Solvent dyeing has the disadvantage that organic solvents capable of swelling polyester film and therefore suitable for the purpose are in general not environmentally friendly. Nevertheless, the amount of swelling agent present in the dye mixture and in the film, even when such commercial liquid disperse dyes are used, is very much less when the method of the present invention is used than in prior art solvent dyeing and solvent-assisted dyeing processes, perhaps by a factor of 20 or more. The dyed films were then exposed in a zenon weatherometer for 500 hours and the change in colour (degree of fading) assessed using a spectrophotometer. The dye mixture may contain 5 to 50% by weight of the organic liquid, more preferably 5 to 40%, further preferably 10 to 25%. CPFILMS INC.,VIRGINIA, Owner name: No. Alternatively, the film may be washed by passage through cold or warm water white being subjected to ultrasonic vibrations. The organic liquid may for example be an alcohol, for example ethanol or isopropanol, a ketone, for example acetone or methyl ethyl ketone, or an ester, for example ethyl acetate. (3) heating said film to cause said dyestuff to migrate from said layer into said film. Such viscosities are much lower than 500 centipoise. The aqueous dispersion contains 1-4% dye, 0.1% sodium alginate and 0.003% of a sodium aryl sulfonate wetting agent. Dongguan Yalan Packing Materials Co., Ltd.

Dispersol Blue C-3R (a liquid disperse dyestuff available from ICI plc) was coated onto a sample of polyester film 25 micron thick by drawing a wire-wrapped stainless steel rod (metering rod) over the film to simulate gravure printing. The absorber is substantially uniformly dispersed through such a film. The composition may contain 1-6% by weight dyestuff suspended or dissolved in the composition. Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. 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. No. Very streaky with evidence of gels and dye spots. Worse than 36, More defined streaks than 40, but less unevenness, Very fine streaks. The dye mixture is preferably coated onto the film by use of a gravure printing roll in a gravure printing process, more preferably by reverse gravure printing. The dyestuff may be applied to the film in the form of a uniform layer by any convenient coating or printing expedient, for example a gravure roll. Assignors: CP FILMS INC., FLEXSYS AMERICA L.P., SOLUTIA INC. For example, in a dyed film 25 micron thick it may be observed that 90% of the dyestuff is to be found in a surface region amounting to about 10 or 20% of the thickness and that the remaining 10% of the dyestuff is to be found in the remaining 90 or 90% or so of the thickness. The dye is generally applied to the film in solution in the solvent, either at the same time as or subsequently to the swelling treatment. It is difficult in such a process to maintain the composition of the dye bath as accurately as could be desired. Many such dyestuffs are available commercially. 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. All these dyestuffs were obtained from Ciba-Geigy in the form of liquid dyestuffs containing approximately 40% solids and approximately 20% 1,2-propylene glycol. It was found that coating quality was generally better when the dye mixture contained IPA. DEUTSCHE BANK TRUST COMPANY AMERICAS, AS COLLATERA, Free format text: In a preferred embodiment, at least one of said dyestuffs is an ultraviolet absorber. This defect has been attributed to the presence of residual swelling agent in the film. The SCMC used was Courlose F-350 available from Courtaulds plc. The layer is usually dried before the heating and migration step. The vapour pressure of type D dyes increases the least rapidly with temperature. SECURITY INTEREST (SEE DOCUMENT FOR DETAILS). The dye mixture may contain one or several dyestuffs. Our PET films offer excellent barrier properties for such environments.

Better than 33. The absence or very low level of swelling agent in the dye mixture used in the method of the invention is an advantage in the heating step. The dry coating weight (DCW) of samples of the film was measured gravimetrically. Save 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. Show cookie information One known method of dyeing a polyester film with a disperse dye relies upon swelling the film with an organic solvent. The minimum total solids content of the dye mixture by weight is preferably 0.1%, more preferably 0.2%, further preferably 2% or 5%. In one embodiment of the invention, the film passes between the reverse gravure roll and an impression roller. Coloured polyester film prepared according to the method of the invention may be laminated to another film, for example a metallised polyester film. 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. 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. The disperse dyestuff generally penetrates only a relatively small distance into the film in the practice of the process of the invention. Coloured polyester films exhibiting an optical transmission of less than 20%, less than 10%, less than 5% or around 2 % at an absorption maximum of such a dyestuff component can be readily prepared. Similar to 35. mylar 015mm polyester roll insulation larger If the degree of leveling through the film is greater, it may be observed that 90% of the dyestuff is to be found in a surface region amounting to about 50% of the film thickness. It is known that commercial liquid disperse dyes often contain a swelling agent, for example 10-25% or around 20% ethylene glycol or propylene glycol. ABLECO FINANCE LLC,NEW YORK, Free format text: Saves the settings of the visitors selected in the Cookie Box of Borlabs Cookie. Average particle size is preferably less than about 1 micron.

The invention provides a process for producing a coloured polyester film including the steps of: (1) providing a dye mixture which has a viscosity of no more than 500 centipoise at ambient temperature and which is a suspension of at least one disperse dyestuff in a solution of a thickener in water; (2) coating said dye mixture onto a polyester film to form a layer; and. Dimensional stability PET films offer excellent resistance to shrinkage, curling or distortion. The vapour pressure of type A dyes increases the most rapidly as the temperature is raised and consequently fixation occurs more rapidly and at lower temperatures with type A dyes than with the other types.
The resulting high quality film was opaque with an Optical Density of 3. The process can be used to prepare films which contain one or more dyestuffs in one surface region of the film and one or more different dyestuffs, for example an ultraviolet absorber, in the other surface region of the film. The dye mixture may contain a minimum of 0.1%, preferably 0.5%, more preferably 2%, by weight of the dyestuff on a dry weight basis. The BRY mix used in some of the trials consisted of dyes B and R together with C.I. In some cases, isopropyl alcohol (IPA) was added to the resulting mixture. The process of diffusion may be assisted by heating. Dyecontrol By Loris Bellini E. Zaitex S.R.L. It may generally be preferred for simplicity to dye only one side of the film. SHORT-FORM JUNIOR PATENT SECURITY AGREEMENT;ASSIGNOR:CPFILMS INC.;REEL/FRAME:014718/0276, Free format text: It is an advantage of the invention that low concentrations and amounts of thickener can be used, since the thickener can be washed off the film and discarded after use. The dye-carrier is a material which has a noticeable swelling action on the film and consequently accelerates dyeing so that, for example, dyeing can satisfactorily be carried out at a temperature in the range 80-100 C. with a dyeing time of about 1-3 hours. It has been found that films treated according to the process of the invention generally shrink by no more than 0.5 to 2% during the heating step, for example around 1% at 180 C. or around 2% at 200 C. It is known to be difficult in the prior art processes of solvent dyeing and solvent-assisted dyeing to remove all the swelling agent after dyeing.
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. Einige von ihnen sind essenziell, whrend andere uns helfen, diese Website und Ihre Erfahrung zu verbessern. polyester film mylar milky ecplaza The Quality Index of the dyed film was assessed to be 1. 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. It penetrates into the surface region adjacent to and underlying the coated surface and is substantially all present in this surface region.
Dye mixtures which are essentially free of any swelling agent may be preferred in the method of the present invention. The heating step can often be carried out at temperatures lower than conventionally used for transfer printing of disperse dyes, which printing is often carried out at 200-210 C. It is generally thought that disperse dyes migrate during transfer by sublimation. Our color pet film made of special chip provide an excellent surface to print your graphics. Outsidecoatingforwrappingboxorbagforfood,medicine,cosmetic,gift,liquoretc. The layer is then dried, and the film heated to 200 C. to cause diffusion of the disperse dye from the dye paste into the film. Lots of dye spots. Some of them are essential, while others help us improve this site and your experience. B. IP-Adressen), z. This technique can be used to obtain excellent quality film with very few defects. (Dispersol is a Trade Mark of ICI plc.) The wet layer may be dried at ambient or elevated temperature, for example on steam-heated rollers or in an electrically-heated oven at around 80-120 C. or by exposure to infrared radiation. Under such conditions, the washing liquor may be very lightly coloured or nearly colourless. The viscosity of the dye mixture is measured under low shear conditions, for example in an Ostwald viscometer, Brookfield viscometer or Zahn cup. An ultraviolet absorber may alternatively be incorporated in a polyester film by extruding a polyester dope containing the absorber to form a film or by conventional dyeing processes. The coated wet layer is typically a few micron thick, for example 1 to 10 micron thick. Liquid disperse dyestuffs may be preferred for convenience in the practice of the invention. The dye mixture may be made using a disperse dyestuff in powder or liquid form. polyester film metallic glitter colored larger 08/443,688, filed May 18, 1995 (now abandoned), which is a continuation of U.S. patent application Ser. The film was then heated at 200 C. for 30 seconds to cause migration of the dye into the film and then washed with water. Such liquid disperse dyestuffs commonly contain around 20-50% by weight, for example about 40% by weight, of the dyestuff, and are viscous pastes which commonly have a viscosity around 2000-5000 centipoise. The thickness of the film may be 5 to 250 micron, more often 10 to 50 micron, for example 12.5 or 25 micron.

Einige von ihnen sind essenziell, whrend andere uns helfen, diese Website und Ihre Erfahrung zu verbessern. The most appropriate heating time at any particular temperature can be selected on the basis of experiments in which the increase in colouration of samples of film with time at that temperature is monitored. The former of these techniques is the one more commonly used. Another known method of dyeing a polyester film utilises a suspension of disperse dye in a mixture of water and an organic solvent which swells the film. Disperse dyestuffs are commonly classified as type A (having a molecular weight around 250), B, C or D (having a molecular weight around 450). Drawingpaper,documents,advertisement,digitalprinting,showboard,etc. Even if the dye mixture contains a low level of swelling agent, for example when a liquid disperse dye containing a swelling agent as mentioned above is used, much less swelling agent is present than in prior art solvent dyeing or solvent-assisted dyeing processes.
