Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a vine patch that can be welded to two bags of clothing, two pairs of footwear, two gloves, etc. by a simple heating press.

This invention relates to synthetic resin decorative pieces such as appliques.

Conventional Art Decorative pieces made of synthetic resin consisting of a thermoplastic synthetic resin sheet, a foamed thermoplastic synthetic resin sheet, and a substrate have already been disclosed in Japanese Patent Publications No. 43-15353 and Japanese Patent Publication No. 50-986.
The one shown in Publication No. 1 is known.

The synthetic resin decorative pieces disclosed in these publications are all adhered to substrates such as clothing fabrics or bag fabrics using a high-frequency welder.

It has also been proposed that the base material of the synthetic resin decorative piece is cut wide enough to extend beyond the outer contour of the decorative piece, and then attached to the fabric of clothing, two bags, one glove, etc. by sewing with a sewing machine. There is.

Problems to be Solved by the Invention Since the decorative piece made of synthetic resin shown in the above-mentioned publication is bonded using a high-frequency welder, it is necessary to transport clothing fabrics, bag fabrics, etc. to a high-frequency welder processing factory for processing. However, it has the disadvantage of increasing transportation costs.

In addition, in the case of synthetic resin decorative pieces that are cut to a width slightly larger than the outer contour of the decorative piece and then sewn onto clothes, bags, gloves, etc. by machine sewing, the base material of the known synthetic resin decorative pieces is cut slightly wider than the outer contour of the decorative piece. The decorative pieces may not be in the same position, spoiling the appearance, or the sewing thread may cause the decorative piece to tangle, causing the outer edge to curve upwards. There is a risk of water or washing liquid entering and damaging the decorative pieces.Furthermore, decorative pieces with complex shapes are difficult to sew and are likely to peel off due to thread breakage, and their adhesion is relatively weak. . Moreover, it takes time to sew, which increases the cost. The sew time also varies depending on the size and shape of the decorative piece. The skill level of the worker also affects the sew time and the quality of the finish. There are problems such as discrepancies.

Therefore, the first aspect of the invention is capable of firmly fixing a decorative piece made of synthetic resin having a three-dimensional pattern by just one operation called a hot press, regardless of the shape, size, skill level of the worker, etc. It was invented for the purpose of adhering clothes, bags, gloves, etc. to make them look beautiful and have high production efficiency.

The second invention of the present invention is a two-bag garment made of cloth that can achieve the above-mentioned object.

It was invented for the purpose of making a 5-by-5 decorative piece by firmly adhering it in the same process to give it the same material feel as gloves and the like.

Means for Solving the Problem The first invention comprises a synthetic resin sheet as a surface layer, a foamed synthetic resin sheet as a middle layer, and a base material as a lower layer, and the synthetic resin sheet is a foamed synthetic resin sheet as a middle layer. The sheet is made of thermoplastic synthetic resin that exhibits adhesive ability at the same time as the sheet, and the middle layer synthetic resin foam sheet is made of thermoplastic synthetic resin that exhibits adhesive ability at 1500 ON 200°C, and both sheets have an outer contour line and a pattern contour line. In this case, it is bonded to the base material by the adhesive ability, and the entire lower surface of the base material is heated to 110°C.
By adopting a structure in which an adhesive film made of a thermoplastic synthetic resin that exhibits adhesive ability is attached to the front and back, and the second invention of claim The synthetic resin sheet is composed of a surface layer synthetic resin sheet, a middle layer synthetic resin foam sheet, and a lower layer base material, and the synthetic resin sheet is made of a thermoplastic synthetic resin that exhibits adhesive ability at the same time as the middle layer synthetic resin foam sheet, The synthetic resin foam sheet in the middle layer is made of a thermoplastic synthetic resin that exhibits adhesive ability at 150°C to 200°C, and the fabric, the synthetic resin sheet, and the synthetic resin foam sheet have an outer contour line and a pattern contour line. is adhered to the base material by the adhesive ability,
The above object has been achieved by having an adhesive film made of a thermoplastic synthetic resin that exhibits adhesive ability at around 110° C. adhered to the entire lower surface of the base material.

In the first aspect of the invention, the main part of the decorative piece consists of a synthetic resin foam sheet in the middle layer that develops adhesive ability at 150°C to 200°C, and a surface layer that develops adhesive ability at the same time as the sheet. Due to its adhesive ability, the synthetic resin sheet is adhered to the lower layer base material at the outer contour line and the pattern contour line to form a three-dimensional pattern.
Since an adhesive film made of a thermoplastic synthetic resin that exhibits adhesive ability at around 0°C is attached, the adhesive film of the synthetic resin decorative piece is attached to the adhesive part of the fabric to be adhered, such as clothes, bags, gloves, etc. When the adhesive film is heated in a single step by pressing the adhered surface with a flat hot plate from the back side of the adhered fabric to a temperature at which it exhibits adhesive ability, the synthetic resin decoration is created. The three-dimensional patterned portion consisting of the synthetic resin sheet on the surface layer and the foamed synthetic resin sheet on the middle layer of the piece does not undergo thermal deformation, and only the adhesive film melts, and the entire lower surface of the base material is bonded to the fabric to be bonded. In this adhesion process, if the synthetic resin decorative piece is supported by a pressure receiving plate such as a synthetic beam, the gas in the synthetic resin foam sheet expands due to the heat during hot pressing, and the surface layer of the synthetic resin sheet and the foam The three-dimensional pattern portion made of the sheet maintains a markedly bulging state while pressing the pressure receiving plate, and the three-dimensional pattern is not deformed by heat.

The second claimed invention has exactly the same effect as the first claimed invention described above, and since it includes a fabric as an outer skin, it has a three-dimensional pattern that has the same texture as the fabric to be adhered. To highly efficiently and firmly adhere decorative pieces without sewing them.
