  In view of the above-mentioned problems, the object of the present invention is to weave, knitting, embroidery, sewing, bonding and other means to sheets made of fabric, knitted fabric, embroidery, sewn fabric, etc., leather, paper, plastic sheets, etc. It is to provide a flat foil yarn for forming which produces a unique three-dimensional effect and a unique luster similar to a twisted silver yarn, and a method for decorating sheets using the same.

  The flat foil yarn for modeling of the invention according to claim 1 that solves the above problem is a flat foil yarn including at least two base material layers excluding a coating film and an adhesive layer, and is disposed on one side. The base material layer is formed of a material having low heat shrinkability or non-heat shrinkability in the yarn width direction and the yarn length direction, and the base material layer disposed on the other side has heat shrinkability in the yarn width direction. And is formed from a material having low heat shrinkage or non-heat shrinkage in the yarn length direction.

  According to the configuration of the flat foil thread for modeling, the flat foil thread for modeling is introduced into the fabric and other sheets by weaving, knitting, embroidery, sewing, bonding, and other means, and disposed on the other side. When the base material layer is heat-treated at a required temperature causing heat shrinkage in the yarn width direction, the base material layer disposed on the other side having heat shrinkability in the yarn width direction in the forming flat foil yarn is The flat foil yarn for modeling is more contracted in the yarn width direction than the base material layer disposed on the one side having low heat shrinkability or non-heat shrinkability in the yarn width direction and the yarn length direction. The base material layer disposed on the other side is used as an inner surface, and is biased so as to be bent and deformed along the yarn width direction. The flat foil yarn for modeling is not seen in ordinary flat foil yarns having a rectangular cross section and a flat surface due to the change in the cross-sectional shape and the surface shape due to the bending deformation along the yarn width direction as described above. A unique three-dimensional effect and a unique gloss similar to the twisted silver thread will be exhibited, and furthermore, a specific three-dimensional effect and unevenness will be given to the sheets in which the flat foil yarn for modeling is introduced.

The provided base material layer has lower heat shrinkability or non-heat shrinkability in the yarn width direction and the yarn length direction than the base material layer disposed on the one side in the yarn width direction and the yarn length direction. Because of the large shrinkage, the shaping flat foil yarn is biased so as to be curved and deformed along the yarn width direction and the yarn length direction with the base material layer disposed on the other side as an inner surface. The shaping flat foil yarn is not only due to the change in the cross-sectional shape and the surface shape due to the bending deformation along the yarn width direction as described above in the case of the shaping flat foil yarn according to claim 1, The cross-sectional shape and the surface shape curve change due to the bending deformation along the yarn length direction are also taken into consideration, and not only in a normal flat foil yarn having a rectangular cross section and a flat surface, but also in claim 1 The sheet has a unique three-dimensional effect that exceeds the case of the described flat foil yarn for modeling and a unique luster similar to a twisted silver yarn, and further to the sheets into which the flat foil yarn for modeling is introduced.
