Abstract: This invention relates to heat transfer presses and more particularly to the transferring of a colored picture printed on paper to polyester knit goods by means of heat and pressure. The polyester cloth heat softens while the ink vaporizes and passes through the intercies of the cloth. The cooling of the cloth locks the vapors in the material producing the effect of a dyeing process.

Abstract: An apparatus in which successive layers of charged particles are transferred, in superimposed registration with one another, to a sheet of support material. The sheet of support material is reciprocated so that successive forward movements thereof are in synchronism with the movement of the charged particles. On the return movement, the sheet of support material is located in a position to initiate the transfer of the next successive layer of particles in superimposed registration with the previously transferred layer of charge particles during the forward movement thereof.

Abstract: A dry release sublimation transfer is provided which includes a temporary backing sheet having disposed thereon a sublimation transfer design layer formed of one or more sublimation transfer inks, and a polymeric coating disposed in contact with such design layer. In one embodiment, the design layer is first printed on the backing sheet employing conventional printing techniques and thereafter the polymeric coating is applied over the design layer. In another embodiment, the polymeric coating is first applied to the backing sheet and thereafter the design layer is printed over the polymeric coating. The dry release sublimation transfer is applied under heat and pressure to a substrate to be decorated, such as cotton fabric or a cotton-polyester fabric, thereby causing the polymeric coating to soften and penetrate into the substrate and upon cooling securely bond the design layer to the substrate.

Abstract: Pile fabrics with a pile containing thermoplastic fibers are thermoprinted with a pattern, the contact pressure between the pile fabric and the thermoprinting web in the heating zone being such that about 40 to 60% of the pile is compressed, and immediately afterwards relief-formed and/or surface formed while still hot with a pattern which bears a strict relationship to the thermoprinted pattern. A machine for carrying out this process comprises a thermoprinting unit with adjustable contact pressure and a relief-forming and/or surface forming patterning unit which functions in synchronism and coordination therewith.

Abstract: A method for the color printing of yarns in a space-dyed pattern so that the yarns can be used in a process to form the pile of a fabric, and form a color pattern in the fabric said method comprising printing a pattern of parallel color strips on a transfer sheet using sublimatic dyestuffs, and then causing, by the application of heat, release of said dyestuffs from the sheet, whilst the sheet is in face to face contact with a bank of parallel yarns. It is preferred that an air flow through the yarns be created during the dyestuff release so as to draw the vapor phase dyestuffs into and round the yarns.

Abstract: A method of printing on thermographic paper according to which the heat for causing the imaging color change in the thermographic coating is generated by means of current in a portion of the coating dampened by a thin film of a conductive salt solution which is dispensed on the thermographic coating. The current is generated by a printing head having spaced electrodes in contact with the dampened portion of the coating. The conductive salt solution may be deposited on the thermographic coating in liquid film form, combined with a thermographic material to form a conductive coating for printing in the dry state, or mixed with the thermographic material in liquid form and dispensed on plain paper in a thin film in the path of the writing head.

Abstract: Dry transfer printings are obtained by bringing the printed surface of a temporary carrier sheet into face-to-face contact with the surface of a substrate sheet to be printed, forming the joined sheets into a coil and heating the coil to a temperature and for a time period sufficient to cause transfer of transferable dyestuff from the printed surface of the temporary carrier to the surface of the substrate to be printed.

Abstract: A pattern is placed on a porous transfer sheet by the use of sublimable dyes. Carpet face yarns are tufted into a backing material.
