Description

  The present invention relates to a flocked laminate sheet, a flocked transfer sheet, and a method for producing the same.

  As is well known, in a flocked transfer sheet used for transferring short fibers on which a pattern such as characters or designs is applied to a transfer object such as clothing, a coloring agent for applying the pattern to the short fibers As a sublimation dye is used.

  For example, in Patent Document 1 described later, a transfer pattern layer is previously formed on a mount using a dye that sublimates, and then a paste whose adhesive strength is reduced by heating is applied on the transfer pattern layer. A pile pattern is formed by electrostatically flocking hydrophobic fibers through the transfer pattern layer on the mount, and then heated under reduced pressure so that the dye is infiltrated and held in the fibers of the pile. A method for producing a flocked transfer sheet is disclosed in which the pile pattern is made peelable from the mount and finally an adhesive resin layer is formed on the pile.

  Further, in Patent Document 2 described later, a heat-sublimable or heat-vaporizable dye and a pattern layer mainly composed of a binder are formed on the upper surface of the mount, and then the water-soluble property is formed on the entire surface of the pattern layer or mount. A dye contained in the pattern layer is formed by forming a paste layer mainly composed of a polymer, further flocking a flocking layer made of short fibers into the paste layer to form a multilayer sheet, and then heating the whole. Is sublimated or vaporized to escape most of the dye from the pattern layer to form an escape pattern layer, and the escaped dye is diffused and penetrated into the flocking layer through the glue layer, and the short fibers forming the flocking layer are gasified. A method for producing a flocked transfer paper is disclosed in which a flocked layer is formed into a dyed flocked layer by phase dyeing, and an adhesive resin layer is formed on the upper surface of the dyed flocked layer.

However, in any of the above flocking transfer sheet manufacturing methods, the sublimation dye is directly printed on the mount, and when sublimation dye is sublimated to dye short fibers, a part of the sublimated dye is transferred to the mount side. Since it penetrates, it becomes difficult to be sufficiently dispersed to the short fiber layer side, and accordingly, the short fibers are not dyed vividly, and the color of the transfer pattern formed after transfer is blurred.
