Description

DETAILED DESCRIPTION OF THE INVENTION The present invention forms a concavo-convex pattern on the surface of a decorative object that gives a three-dimensional sense of perspective, and can be easily attached to clothes etc. with an iron or the like.
The present invention relates to a method for manufacturing a synthetic resin decorative body whose uneven pattern does not change even when dry-cleaned.

Traditionally, this type of synthetic resin decoration consists of a vinyl chloride sheet on the surface, a foamed synthetic resin sheet on the inside, and a vinyl chloride sheet on the back.These are polymerized and the edges of the pattern are heated and pressed using image frequency waves and welded. It expressed a three-dimensional pattern.

However, since the surface of this type of decorative body is a vinyl chloride sheet, is this decorative body? Clothes attached cannot be ironed, and if dry cleaned, the decorations will be deformed by the cleaning yeast, so the decorations must be removed and sent for dry cleaning. However, some XA7s have the disadvantage that they cannot be dry cleaned.
m. In addition, sewing was the main method for attaching decorations to clothing.

The present invention solves these drawbacks and provides a method for manufacturing a synthetic resin decorative body that can be dry-cleaned, attached to clothing with an iron, and has a three-dimensional appearance that can be ironed.

To explain the structure of an embodiment of the present invention, as shown in FIG.
c. The printing layer 1 is placed on the bottom surface, and then a medium-hard vinyl chloride sheet 3, a polyurethane sheet 4, and a nylon sheet 5 are polymerized in this order. Next, in order to remove air from these polymerized sheets, the upper and lower surfaces are polymerized and pressure welded at a temperature of 930° C. to 50° C. to remove air between each polymerized surface.

The design pattern shall be printed using synthetic resin printing ink, and if the polyurethane sheet 2 is opaque, the design pattern may be printed on the front surface, but it should be printed on the back surface to prevent the ink from peeling off. It is preferable.

The melting temperature of nylon 5, which is polymerized on the bottom surface, is 70°C.
Nylon 12 having a temperature of about 100° C. is suitable.

Next, a fusing blade portion 8 is provided at a position inside the outer contour line of a portion corresponding to the outer contour line 7 of the decorative body 6, and a slope 8 inscribed therein.
The flat suppression part 9 following A is further marked with letters at its inner position.
An upper mold 15 having a concave circumferential wall 11 that matches the graphic bulge 10, a suppressing part 12 on the inside thereof, and a central concave part 14 that matches the characters, figures, and the bulge 13 on the inside thereof; The corresponding upper mold 16 is provided with all the circumferential grooves 17 that have internal groove walls 17A into which the cutting blade 8 of the upper mold 15 fits and cuts.

Next, to explain the manufacturing method, the polymerized sheets that have been polymerized in the above-mentioned order and with the air removed between the sheets are placed on the lower mold 16, and the recessed peripheral wall 11 and central recessed portion 14 of the upper mold 15 are completely covered. , each letter/figure bulge 1 of the top polyurethane sheet 2
0.13, and the polyurethane sheet 2.4 does not melt, but the medium-hard vinyl chloride sheet 3 polymerized below it melts. The fusing blade part 8 of the mold 15 fuses the outer contour line 7 part, and at the same time presses the suppressing part 9. is formed, and the outer edge portion 18 is removed along the outer contour #Q contour line 7 cut by the fusing blade part 8.

The present invention having the above-mentioned configuration has the advantage that the upper and lower polyurethane sheets 2.4 do not melt, and the upper and lower polyurethane sheets 2.4 do not melt.
Since the medium-hard vinyl chloride sheet 3 polymerized in between was heated and pressurized at around 130° C., which melts it, the bulging portions of letters and figures l
Medium hard vinyl chloride melts and flows into O and the letter figure bulging part 13 to form a bulky three-dimensional letter figure pattern, and each suppressing part 9 and 12 is compressed to a low volume to create a decorative body with a three-dimensional sense of perspective. The edges of the polyurethane sheet 4 and the lower polyurethane sheet 4 and the nylon 5 are bonded together, and the medium-hard vinyl chloride sheet 3 is wrapped in the polyurethane sheet 2.4, so the decorative body 6 is dried using a solvent with particularly strong detergency for dry cleaning. Since it is not affected by polyethylene, it is possible to provide a decorative body that can withstand dry cleaning.

In addition, since the nylon sheet 5'ff is polymerized on the bottom surface of the decorative body 6, the decorative body 6 can be attached to clothing or bags by melt bonding with an iron after heating at approximately 70°C to 100'C. Sewing is not necessary.

Furthermore, if the medium-hard vinyl chloride sheet 3 in the character/figure bulge 1o and the character/figure l bulge 13 of the decoration 6 is at a daily temperature of 120' CC, the decoration attached to clothing will not melt. It has excellent features such as the character 〉'' shaped bulging part 10.13 will not be crushed and deformed even if it is ironed with the ``6'' attached.
