Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a three-dimensional color pattern on a perforated fabric, such as a coarse gauze, a mesh fabric, a mesh knit fabric, etc.

Traditionally, to form colored patterns on transparent fabric, embroidery is done with colored threads, gold, or silver threads, or colored threads, gold, or silver threads are woven into the weft using pattern paper on a loom, and the colored threads and It relies on a method of removing unnecessary parts other than the gold and silver thread patterns with scissors.

All of these conventional methods require a lot of tedious manual work, resulting in low productivity and expensive products. Moreover, the three-dimensionality was insufficient because it was due to the colored threads, gold, and silver threads themselves. SUMMARY OF THE INVENTION An object of the present invention is therefore to provide a method that can industrially and simply form a color pattern on a perforated fabric, and can also make the color pattern appear rich in three-dimensional effect.

Other objects of the invention will become apparent from the following description. The method of forming a three-dimensional color pattern on a translucent fabric according to the present invention involves placing a transfer sheet, in which a colored thin film with low breaking strength is laminated on a release film layer formed on a base sheet, with the colored thin film side facing up. Place it on a horizontal surface plate, place a weir frame of an appropriate depth on top of it, fill the weir frame with a photocurable liquid resin and insert a perforated fabric, and expose it to light through the original pattern of the desired pattern. The photocurable liquid resin in the portion corresponding to the original pattern is cured, and by this curing, the portion of the colored thin film of the transfer sheet corresponding to the pattern formed by the cured resin is integrated with the cured resin. Peel off the sheet and remove the uncured resin, thereby revealing the three-dimensional pattern made of the cured resin on the perforated fabric, and transferring the colored thin film on the transfer sheet to the perforated fabric according to the pattern made of the cured resin. Characterized by.

According to the method of the present invention, a transfer sheet in which a colored thin film with low breaking strength is laminated on a release film layer formed on a base sheet is placed on a horizontal surface plate with the colored thin film side facing up. A weir frame of an appropriate depth is placed on top, and the weir frame is filled with a photocurable liquid resin and a perforated fabric is placed therein, which is exposed to light through the original pattern of the desired pattern, and the light of the part corresponding to the original pattern is exposed. Curing the curable liquid resin.

By this curing, the portion of the colored thin film on the transfer sheet corresponding to the pattern formed by the cured resin becomes integrated with the cured resin. Therefore, next. By peeling off the transfer sheet and removing the non-cured resin (resin in areas other than the pattern-corresponding areas), the colored thin film on the transfer sheet will be transferred to the perforated fabric according to the pattern created by the cured resin, The colored thin film in areas other than the areas corresponding to the pattern will remain on the transfer sheet as is. The weir frame previously placed on the transfer sheet may be removed when the uncured resin is removed. According to the present invention, a color pattern is applied to a perforated fabric using a photoprinting method and a transfer technique.
It can be formed industrially and simply.

Furthermore, in the present invention, the weir frame placed on the transfer sheet is filled with the photocurable liquid resin and the perforated fabric is inserted, so that the resin can be removed while the perforated fabric is submerged in the liquid resin. Therefore, the pattern formed by the cured resin can be a pattern rich in three-dimensionality.

Furthermore, in the present invention, the above-mentioned three-dimensional pattern revealing and transfer process is performed multiple times on the same perforated fabric, and at that time, patterns of different depths are placed in the weir frame for pouring the photocurable liquid resin in ascending order of depth. By using different types of resins, it is possible to vary the degree of elevation of the three-dimensional pattern created by the cured resin. In the present invention, as a transfer sheet, a colored thin film and a metal thin film each having a small breaking strength are used in the release film layer formed on the base material sheet, or a colored thin film, a metal thin film, and a colored thin film are used as a transfer sheet. A structure in which these are sequentially laminated is applied.

The former transfer sheet adds metallic luster to the color pattern, while the latter transfer sheet reveals a composite color pattern and metallic luster. In the present invention, the colored thin film with low breaking strength can be formed by metal vapor deposition or by printing synthetic resin or other appropriate material.

In the case of printing, it may be single color printing or overprinting of two or more colors. In the present invention, any known per se can be used as the photocurable liquid resin.

The uncured resin may be removed by an appropriate method such as washing with water or vacuum suction. After removing the uncured resin, it is preferable to further irradiate the cured resin with light for an appropriate period of time (usually several minutes) to stabilize the curing of the resin. Embodiments of the method of the present invention will be described below with reference to the drawings.

The transfer sheet A includes a base sheet 1, a release film layer 2 formed on the sheet, a colored thin film 3 with a low breaking strength laminated on the layer, and a colored thin film 3 with a low breaking strength formed thereon. The metal thin film 4 is further provided with a colored thin film 5 having a low breaking strength and laminated thereon.

The metal thin film 4 and the colored thin film 5 or the colored thin film 5 of the transfer sheet A may be omitted. Place the transfer sheet A on a horizontal surface plate (not shown), place the weir frame B of an appropriate depth on top of it, fill the light-curing liquid resin 6 in the weir frame, and add the hole fabric. Enter 7.

Next, the photocurable liquid resin in the weir frame B is exposed to light through a negative or positive original of a desired pattern, and the photocurable liquid resin in the portion corresponding to the original pattern is cured.

After that, the uncured resin is removed and the transfer sheet A is peeled off.

At some point, a three-dimensional pattern 8 made of a colored cured resin formed by the colored thin films 3 and 5 and the metal thin film 4 is exposed on the perforated fabric 7.
