[0142] pass Figure 1 ~ Figure 4 The shown method produces a decorative sheet composed of a soft polyurethane film 31 , a color migration preventing layer 5 formed of a color migration preventing film 151 of PVDC, a thermal adhesive film as an underlayer 7 , a carrier film 33 and a release paper 75 . In addition, except not using the color migration prevention layer 5, the decorative sheet for comparison was manufactured using the same material and manufacturing method.
[0143] Additionally, by Figure 5 ~ Figure 7 The method shown produces a decorative sheet composed of a soft polyurethane film 31, a color migration preventing layer 5 formed of a PVDC color migration preventing film 151, and a polyester fabric as a lower layer 7, except that the color migration preventing layer 5 is not used. Except for this, a decorative sheet for comparison was produced using the same material and production method.
[0144] also according to Figure 11 , Figure 12 In the embodiment s...

Abstract
Provided is a decorative piece to which the dye of a garment is prevented from migrating and which suffers no separation between the constituent members and can be produced by means of high-frequency induction heating. The decorative piece comprises: a pattern piece (3) which has an outer contour and a pattern formed therein and is constituted of a thermoplastic synthetic resin; a lower layer (7); and a migration-preventive layer (5) disposed between the pattern piece (3) and the lower layer (7), the layer (5) having the same outer contour as the pattern piece (3), being fusion-bondable to both the pattern piece (3) and the lower layer (7), and being capable of preventing dye migration. The migration-preventive layer (5) comprises a migration-preventive film (51) formed from an ethylene / vinyl alcohol copolymer or polyamide-MXD6 or comprises a migration-preventive film (151) formed from polyvinylidene chloride.
Description
technical field [0001] The present invention relates to decorative sheets such as logos, emblems, appliqués, and labels attached to clothing, etc., and more particularly relates to clothing, etc., which are polyester fabrics dyed with disperse dyes or sublimation printing A decorative sheet in which dye color migration occurs on clothing or the like. Background technique [0002] A method of manufacturing decorative sheets such as signs, badges, inlays, labels, etc. by using a thermoplastic synthetic resin film as a raw material and subjecting it to high-frequency induction heating, and the decorative sheets manufactured by this method are known, for example, as described in the following patent documents 1, 2, and 3. public technology. [0003] When the decorative sheet composed of the pattern sheet 3p and the lower layer 7p is produced by high-frequency induction heating with the thermoplastic synthetic resin film 131q and the lower layer material 171q as the material of ...
