Description

Sandwich cake button and manufacturing method thereof

The present invention relates to a garment accessory, and more particularly to a button having a sandwich-like structure, and the present invention also relates to a method of manufacturing the sandwich cake button. Background technique

With the continuous improvement of living standards, people have put forward higher requirements for the aesthetics of clothing. As an important part of the garment, the button, its material, function and especially the design is one of the key points in the design of the garment.

The clothing buttons in the prior art are generally monochromatic, the color is relatively monotonous, and the matching design with the clothing is also limited accordingly. In order to make the buttons look like a variety of colors and various styles, the current practice is to apply oil or silk screen or pad printing on the surface of the button after laser, but this method is inefficient and produced. Buttons feel and texture are relatively poor, the resulting color and pattern are not natural enough, in many cases, the design of the clothing is still not coordinated enough, and some may fade or change color after wearing or using for a period of time.

For the common resin buttons, the liquid resin is generally poured into the roller-type tablet machine or the stick machine which is commonly used in the industry to be solidified and then formed into a blank. Usually, it can only be changed by the color or locality of the resin and the subsequent process. Wait to achieve the pattern and style. It is difficult to produce buttons that are similar to the pattern of ready-to-wear fabrics.

Therefore, it is necessary to develop a new production process, and to manufacture a button having various color patterns and a stable shield according to the needs of various clothing design styles. Summary of the invention

The main object of the present invention is to provide a button with a natural color pattern, a rich design and a stable quality in view of the deficiencies of the prior art, and at the same time provide a button for manufacturing the button. A simple and efficient process.

In order to fundamentally solve the problem that the button color in the existing clothing is single and difficult to perfectly coordinate with the diversification of the clothing design, the designer of the present invention develops a unique style based on years of experience in button development and production. a sandwich cake button, which is mainly composed of a top layer (or upper layer), a bottom layer (or lower layer), and an intermediate layer (intermediate interlayer) disposed between the surface layer and the bottom layer, wherein the surface layer has a certain Transparency, the intermediate layer can have various styles of color and pattern according to design requirements, so that the button product of the present invention can achieve the variety of styles by seeing the color and pattern of the middle layer through the transparent layer. The color and natural color pattern can meet the needs of matching with various design styles of ready-to-wear.

According to a specific embodiment of the present invention, in the sandwich cake button, the material of the top layer (upper layer) may be a resin material or the like which is generally used in the industry, and is usually an unsaturated resin substrate, especially an unsaturated polymer. Ester resin, such as Zhejiang Tianhe Resin Co., Ltd. (Xiangren Town, Linhai City, Zhejiang Province), the production of phthalic acid unsaturated polyester resin DS-988, 602 glue, etc., and these resin substrates should have a certain degree after curing Transparency. The top layer of the button of the present invention may be a fully transparent (highly transparent) resin layer to fully embody the color and pattern as the intermediate layer; it may also be a translucent resin layer, or may be a resin forming the surface layer. Appropriate pigments are added to the raw materials to make them have a specific color (preferably a light color series), which is matched with the color pattern of the intermediate layer and even the clothing to achieve the aesthetic effect of improving the color and pattern of the buttons.

The material of the bottom layer (lower layer) of the button of the present invention may be a resin material or the like which is generally used in the industry, and the material thereof may be the same as or different from the material of the surface layer. Since the bottom layer is generally not exposed when the clothing is matched, the design effect may not be important. Therefore, in the present invention, there is no special requirement for the transparency and color of the resin layer as the underlayer of the button, but it is preferable to have a certain The transparency is matched with the color, material and pattern of the intermediate layer of the surface resin layer, and at least should not affect the button effect seen from the surface layer.

The colorful pattern design of the sandwich cake button of the present invention is mainly derived from an intermediate layer, which is an interlayer having a certain color and/or pattern, and the pattern or color thereof can be based on Choose the style of the clothing to choose from. The intermediate layer may be a mesh fabric layer or other thin layer material having permeability to the uncured liquid resin material of the bottom layer and the top layer, such as various textile fabrics having low density, good permeability and soft texture. It may also be a sheet-like or granular material which is sprayed at a certain density on an under-solidified underlayer to form a flower pattern. However, no matter which material is used, the intermediate layer material and the surface layer and the bottom layer must be tightly combined to ensure good fastness of the button product. Specifically, the intermediate layer of the button of the present invention may be a cloth having various colors and patterns, such as a knitted fabric, a woven fabric, or a woven fabric, a striped fabric, a plaid fabric, a monochrome fabric, etc., or some Other loose-form materials, such as smashed paper, extremely short thread or fiber, etc., may be of the same or similar material as the fabric of the desired garment, depending on the texture; The choice of the style of the clothing to be selected, in this way, can improve the coordination between the button and the clothing, highlighting the texture of the clothing and the overall aesthetic effect.

As apparent from the above, the button of the present invention is a product having a sandwich-like appearance structure by a resin layer or a similar surface layer having a certain transparency and an underlayer substrate sandwiching an intermediate layer having a color and a pattern. The shape and style of the button product can be varied according to the design of the garment. For example, the overall appearance can be various regular or irregular geometric shapes (circular, elliptical, square, diamond, triangle, polygon, etc.); The top layer and the bottom layer have a certain thickness ratio of needle holes (the number of the needle holes are not limited) that need to be provided through or not through the upper, lower and intermediate layers. In summary, the buttons of the present invention can have a variety of design styles to fully reflect the diversity of colors.

It should be noted that the garments described in the present invention include not only the tops, pants, skirts and the like generally described, but also any accessories or daily necessities that may be used in daily life, such as hats, bags, quilts, etc. . That is, the button of the present invention can be applied to any item that may be used with a button, and can achieve an effect that matches the design style of the main body to which it is attached.

In another aspect, the present invention also provides a method for manufacturing the sandwich cake button, which mainly comprises separately preparing a liquid resin raw material for forming a surface layer and a bottom layer, sequentially preparing the bottom layer and laying the middle portion. The layer, the surface layer is further added, and the underlying resin and the top layer resin are controlled to be substantially simultaneously cured by adjusting the content of the curing agent in the liquid resin material. That is, the present invention adopts a prefabricated underlayer sheet (or a facing sheet), and then lays an intermediate layer of textile fabric or other similar material of a network structure, a sheet-like substance, etc. (avoiding a metal material such as a metal material), and adding a surface layer. The method of the sheet (or the back sheet) allows the sheet to achieve a sandwich-like structure.

According to a preferred embodiment of the present invention, the method for manufacturing the sandwich cake button mainly comprises the steps of: sheet production → blanking → car button → polishing → post process. The processes of the blank, the car, the polishing, the post-process and the like are not different from the traditional button production process, and will not be described here. The key step of the production process of the present invention lies in the tableting process, which is different from the one-step forming method of the conventional button. The roller type tableting machine is used to pour the pre-formed underlying unsaturated resin liquid into the drum and Slowly solidify under the action of curing agent; at a certain degree of curing, stop the roller, lay the intermediate layer flat on the bottom layer, turn on the machine, continue to rotate the drum, and pour the pre-formed liquid surface resin material On the covered intermediate layer; when the base resin and the surface resin reach the same level and are suitable for the curing degree of the button blank production, the drum is stopped to obtain the annular sheet. After the annular sheet is cut and removed, the entire sheet is punched into a blank, and the button, the laser, the 7J grinding, the fuel injection, and the like are selectively used to form the sandwich cake button product of the present invention.

A manufacturing method of the present invention described above will now be described in conjunction with a specific process flow:

First, the production process

First, according to the production process requirements, the bottom layer of the button and the surface layer substrate (such as unsaturated polyester resin) are formulated, and the curing agent can be appropriately added. Since the button of the present invention has been developed to enable the finished button to see through the pattern or pattern in the intermediate layer, a visual style matching the ready-to-wear fabric is achieved. Therefore, the top layer of the button of the present invention is generally selected to have a certain transparency.

The tableting process can adopt an ordinary drum type tableting machine, and the prepared bottom unsaturated liquid resin is poured into a vertical drum (the amount of laying can be calculated according to the thickness of the designed button), and is rotated at a certain angular velocity. The liquid resin is spread on the inner surface of the drum with the same thickness under the action of centrifugal force, and is slowly solidified by the action of the curing agent. When the bottom layer is in a semi-cured state, stop the machine and lay the intermediate layer. The intermediate layer is required to be laid flat on the bottom layer to cover the entire bottom layer area (for the sheet-like intermediate layer, the sprayed manner is applied to the bottom layer at a certain density), but it is necessary to prevent the intermediate layers from overlapping and avoid wrinkles and bubbles. Wherein, for the cloth-like intermediate layer, the intermediate layer needs to be cut into the required size of the drum in advance, generally the length of the intermediate layer is required to be equal to the circumference of the drum, and the width is equal to the width of the roll (ie, the width of the back sheet); For the use of a sheet-like material as the intermediate layer, it is only necessary to prepare small pieces of a certain size, depending on the density of the pattern and the number of production. According to a preferred embodiment of the present invention, for some thicker cloth-like intermediate layers, it may be pre-soaked in the resin liquid of the bottom layer (the resin liquid solution is preferably the same as the surface layer resin liquid) for a certain period of time (generally in the form of a fabric) It is completely saturated with the resin, usually 2 to 3 minutes), so that the resin penetrates and adsorbs into the inner layer and the surface layer of the intermediate layer, which is more advantageous for the firm bonding of the intermediate layer of the finished product to the bottom layer and the surface layer.

After that, the liquid surface resin material is poured onto the covered intermediate layer, and the amount of the resin can be calculated according to the design thickness.

In this process, the liquid resin having a certain transparency of the surface layer is evenly laid on the intermediate layer under the action of centrifugal force. At the same time, it is integrated with the liquid resin on the intermediate layer. The resin which has not been completely cured on the bottom layer is also fused with the resin of the intermediate layer to finally achieve simultaneous curing, thereby obtaining the effect of three layers of tight bonding, and ensuring that the bottom of the sandwich cake of the present invention and the surface layer are not cracked.

It should be noted that the intermediate layer structure used in the process of the present invention is too dense, and the permeation performance of the surface layer before the uncured layer and the liquid resin of the bottom layer is poor, and the amount of resin permeating between the pores of the intermediate layer is small, possibly Lead to cracking of the final product. Therefore, it is preferable to use a thin layer material with low density, good permeability and soft texture as the intermediate interlayer, so that the intermediate layer can be tightly combined with the uncured front layer and the underlying liquid substrate under osmosis. To ensure that the finished button products have good firmness.

At the same time, the process that requires critical control is the amount of curing agent added and the curing time. Generally, the content of the curing agent in the resin forming the underlayer is smaller than the curing agent content in the resin forming the surface layer, so that the curing time of the underlayer is longer than the curing time of the surface layer, so that the curing of the underlayer and the surface layer starts from different times but basically Can be completed at the same time. At the same time, you need to control the time of laying the middle layer: the start time of the middle layer laying It should be less than the difference between the curing time of the underlayer and the curing time of the surface layer. For example, if the bottom layer curing time is 30 minutes and the surface layer curing time is 20 minutes, the intermediate layer is preferably laid within 10 minutes after the bottom layer starts to roll to ensure that the bottom layer and the surface layer can achieve substantially simultaneous curing. .

It should be noted that the bottom layer and the top layer mentioned in the above process are strictly referred to as the lower layer and the upper layer, and are formed in the order from the bottom layer to the surface layer of the button. The description is interchangeable. In actual production, it is also possible to lay the surface layer material of the button first, and then lay the bottom layer material (only when the button design is used, the surface layer is used as the bottom layer during the production of the button, and when the button is changed, the surface layer is transferred to the surface layer. Yes, the same effect can be achieved. For the production process, the first layer to be laid can be called the lower layer, and the bottom layer to be laid later can be called the upper layer. This description applies to all relevant descriptions of this case.

Second, the next piece of blank

Since in the production process of the button of the present invention, different amounts of curing agent have been designed in the bottom layer and the surface layer resin formulation, after the surface layer resin is rotated for a certain period of time, the base resin and the surface layer resin are almost identical and suitable. The degree of cure in the production of button blanks. This degree of curing is readily grasped by those skilled in the art. At this time, the drum is stopped, and the ring piece is cut by a blade and then taken off. The entire sheet is then punched into a blank of the desired size in the same manner as a conventional button blank. At this time, the sandwich cake effect blank of the top layer and the bottom layer resin sandwiching the intermediate layer is basically generated.

Third, the car new 1⁄2 process

After the sandwich cake is formed, according to the design requirements of the button shape and style, it is possible to selectively add subsequent processes such as car, laser, water mill, fuel injection and the like. .

Through the above steps, the button having the similar sandwich cake structure of the present invention is formed, and the upper and lower layers of resin sandwich the intermediate layer by the penetrating property, and the transparent resin material selected in the design can make the pattern of the middle interlayer in the button The effect is revealed, and the button is sewn on the same or matching garment as the middle layer color pattern to show the perfect style of the button and the garment. At the same time, the present invention also provides another method for manufacturing the sandwich cake button, (according to the order), selecting the surface layer of the button and the bottom mold, first laying an unsaturated resin on the bottom mold The raw material is placed on the upper layer, and then an unsaturated resin is laid on the intermediate layer, and then the surface layer mold is buckled, and after being thermoplastically molded, it is purified and polished to become the sandwich cake of the present invention. Product.

The intermediate interlayer type and material type and color pattern, and functions, etc. in the design and process of the button of the present invention can be selected according to the product windshield requirements. However, the basic principle of product realization is the same, that is, the surface layer and the bottom substrate have different curing times, and are fused together in a liquid state and a semi-cured state, and the intermediate interlayer is closely combined with the surface layer and the underlying substrate by permeability. One. In summary, the sandwich cake type buckle of the present invention not only differs from the traditional button in appearance, but also changes the production mode of the traditional button, and the required intermediate layer sheet (cloth or other mesh) The structure is added to the interlayer of the bottom layer and the top layer to form a special style, and the permeable property of the bottom layer and the surface layer resin on the intermediate layer and the time difference of curing of the liquid resin material are used, and the intermediate layer is firmly fixed in the middle after curing. , and the bottom layer and the surface layer are firmly combined. According to the method provided by the invention, the large-scale flow processing of the new type of buckle can be realized by using appropriate raw materials and molds, and the process is simple, and the production efficiency can be greatly improved. On the other hand, the buttons of the present invention are rich in color, beautiful in appearance and diverse in variety, and can be harmoniously matched with the ready-to-wear fabrics and design styles, thereby better emphasizing the texture of the clothes and the overall aesthetics, giving a fresh and beautiful feeling. Further, the effect of the button of the present invention is mainly brought about by the inner intermediate layer, and is not affected by the friction of the buckle during washing or wearing, and is not easily faded or discolored, and the quality is stable. Therefore, the button of the present invention and the method of manufacturing the same have a good market prospect. DRAWINGS
