  • Patent number: 6520216
    Abstract: A method for obtaining a woven fabric which comprises continuously unwinding from a single warp beam, a set of parallel warp yarns; passing the set of warp yarns on a whip-roll; forming a shed using heald means; inserting a weft yarn in the shed in the proximity of a face stitch to form a fabric; and finally uniformly pulling and batching the resulting fabric. In one aspect of the invention, the method consists of, in the proximity of the shed opening stitch, heating the warp yarns, and then cooling said warp yarns in the shed before they reach the heald means, characterized in that only part (34) of the warp yarns is heated. In one aspect of the invention, the shed may be defined in the forward movement direction of the warp, for example, by the opening stitch and the face stitch.

  • Patent number: 6447629
    Abstract: A method of digitally printing reactive ink contained in a heat meltable ink layer comprising dyes or pigments or other colorants, using a thermal printer. The ink layer comprises compounds with functional groups capable of reacting with active hydrogen, and compounds with functional groups containing active hydrogen, or functional groups capable of conversion to active hydrogen containing groups. The reactive ink contains one or more blocking agents which prevent initiation of the reaction during thermal printing. An image is thermally printed onto a substrate, at a first temperature, so that the ink is not reacted during the process of printing on to the medium. The image is subsequently transferred or permanently fixed on the substrate by the application of heat and pressure, which removes the blocking agent and reacts the ink, bonding the colorant to the substrate.

  • Patent number: 5580410
    Abstract: A dispersed dye sublimation imaging method of a substrate includes a pre-conditioning step, before the substrate is imaged, which uses controlled heat and humidity. The pre-conditioning step, by raising the surface energy levels of the substrate and thermally stabilizing the substrate before pressured contact in the imaging zone, allows for more precise control of dye sublimation during image. Pre-conditioning also allows: the use of higher temperature dyes; the use of higher temperatures and shorter dwell times in the imaging zone; and/or the use of lower imaging temperatures. The pre-conditioning also provides for greater migration and penetration of the dispersed dye into the surface of the substrate being imaged. The shorter dwell time and thermally stabilized pre-conditioned substrate also reduces movement between the substrate and dye carrier device, which provides for increased resolution of the imaged substrate.

  • Patent number: 5507839
    Abstract: A dye is fixed to a solid material by using a diene or dienophile as the dye, incorporating a dienophile or diene into the solid material, effecting Diels-Alder reaction between the diene and the dienophile or between the dye and the solid material for binding the dye to the solid material. The dyed solid material has an increased dye concentration and prevents dye diffusion with the lapse of time.
