Description

Stereo embroidery method {METHOD FOR EMBROIDERING SOLID}

The present invention relates to a three-dimensional embroidery method, and more particularly to a three-dimensional embroidery method that can enhance the aesthetic three-dimensional appearance and visual effect without increasing the manufacturing cost.

In general, embroidery (刺繡) is to provide aesthetic beauty by embroidering a variety of embroidery patterns, such as trademarks, letters, numbers or figures using a plurality of colors of yarn, such as resin, leather, sheets, and the like.

Embroidery machines of various methods are widely used as an apparatus for forming such embroidery patterns on specific object surfaces.

The embroidery machine is to embroider a pattern or pattern designated by a paper or a diskette using various colored threads on a material such as leather, fabric, and the like, and a gap between a plurality of needles installed at regular intervals on the needle holder of the embroidery machine. (4/4, 8/4, 12/4, 16/4, etc.) to select the embroidery needle that is operated on the rubbing diskette to perform the embroidery process.

On the other hand, the embroidery pattern processed by such a general embroidery machine has a disadvantage that the flatness of the formed pattern is extremely prominent and the three-dimensional feeling is very poor.

Accordingly, in recent years, various structures or embroidery methods have been proposed to implement a three-dimensional effect of embroidery patterns.

As an example, Korean Utility Model Publication No. 20-0339540 (prior application) discloses a three-dimensional embroidery article capable of realizing a three-dimensional embroidered pattern by giving a grass-like effect on the upper surface of the main fabric and an embroidery method therefor.

By the way, in the method of embroidery of the first application, the object of embroidery is prepared, while the woven fabric is laid flat on the bottom, the polyurethane is laid on the upper surface of the woven fabric, and the main fabric is laid on the upper surface of the polyurethane. When the needle passes through the lower part of the object prepared as described above, the thread is cut by using a cutter positioned at the lower part of the object. After the thread is cut, the needle is moved upward. That is, during the process in which the needle is sewn through the upper and lower parts of the object, the cutter located at the lower part of the object cuts a part of the thread passing through the lower part of the object at the same time. Then, after performing the finishing process of the second cutting process with a separate cutter so that the yarn exposed to the surface of the woven fabric has a uniform height, the three-dimensional embroidery is maintained by removing the polyurethane. Finally, a separate adhesive is applied to complete the three-dimensional embroidery so that the thread is not separated from the upper surface of the main fabric.

However, as the embroidery process is progressed by the needle as described above, the thread exposed to the lower part of the object must be cut every time, so the process is very troublesome.

And for this purpose, since the embroidery machine of a special structure with a cutting knife attached to be provided, the manufacturing cost is very high, there is a possible problem only if the main fabric is flat.

In addition, after forming the three-dimensional embroidery, the second cutting process of the yarn unevenly exposed by a separate cutter, and the process of bonding with a separate adhesive so as not to separate the thread from the upper surface of the main fabric should be performed, There is a problem in that the overall manufacturing cost is increased due to a lot of manpower or work time.

On the other hand, due to the nature of the general embroidery machine and embroidery program, it is possible to work with approximately 150 embroidery submersions (grass number) per 1 cm 2.

However, in the case of working with such a number, the density of embroidery (grass) decreases, resulting in the appearance of aesthetic three-dimensional and visual effects, and the problem of embroidering entangled with each other when forcibly increasing the number of embroidery to solve the problem. There is a problem that the workability is remarkably low and the probability of defective embroidery is increased.

The present invention is to solve the above problems, a three-dimensional embroidery method that can enhance the aesthetic three-dimensional appearance and visual effect in a simple manufacturing process without increasing the overall manufacturing cost without using the embroidery machine of the special structure attached to the cutting knife The purpose is to provide.

In order to achieve the above object, the present invention, a primary embroidery preparation step of preparing a first embroidery object by laminating a first separation sheet on the main fabric and the upper surface of the main fabric; A first embroidery step of embroidery by passing a needle of the embroidery machine into the first embroidery object; A secondary embroidery preparation step of preparing a second embroidery object by stacking a second separating sheet on an upper surface of the first embroidery object embroidered in the first embroidery step; A second embroidery step in which the second embroidery object is embroidered, and the embroidery is made by passing the needle of the embroidery machine into the second embroidery object to interfere with the embroidery in the first embroidery step; An embroidery thread fixing step of fixing the embroidery thread to the main fabric so that the embroidery thread is not separated from the second embroidery object; Separating sheet cutting step for cutting the upper portion of the second embroidery object; And a separation sheet removing step of removing the upper portion of the second embroidery object from the upper surface of the main fabric by cutting the upper portion of the second embroidery object so that the embroidery thread is exposed on the upper surface of the main fabric. Provide a method.

As described above, according to an embodiment of the present invention, after preparing the first embroidery object by laminating the first separating sheet on the main fabric and the upper surface of the main fabric, the first embroidery object is first embroidery thread and the first embroidery object. Simultaneously primary embroidery with the first lower thread of the low-temperature fusion splicer so that the embroidery thread can be continuously hooked and twisted, and after preparing the second embroidery object by laminating a second separating sheet on the upper surface of the embroidered first embroidery object, 1 Simultaneously secondary embroidery to the second lower thread of the low-temperature fusion splicer so that the second embroidery thread and the second embroidery thread can be continuously hooked and interfered with the primary embroidery. 2 Cutting and removing the upper part of the embroidery object has the following effects.

First, precisely dense embroidery (grass) is possible, and the three-dimensional appearance and aesthetic effect increase in appearance, thereby improving the quality of the product.

Second, as a conventional general embroidery machine enables a high-density embroidery through a simple manufacturing process, it is possible to reduce the cost for manufacturing a good quality product.

Third, since the bottom of the main fabric is heated to fix the first and second embroidery threads to the main fabric, and the first and second lower threads are fused at low temperature, a separate adhesive is not used, thereby reducing work time and increasing workability. The overall manufacturing cost can be reduced.

Fourth, as the length of the upper portion of the second embroidery object to be cut can be adjusted, the operator can cut the upper portion of the second embroidery object as desired, and thus, the length of the embroidery can be adjusted according to the use. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

A first embroidery object 110 is prepared by stacking the main fabric 111 and the first separation sheet 112 having a predetermined thickness on the upper surface of the main fabric 111.

Here, the first separating sheet 112 serves to maintain the three-dimensional embroidery pattern formed by the first embroidery thread 113 to be embroidered. The thickness of the first separating sheet 112 may be 3 mm to 5 mm to adjust the lengths of the first and second embroidery threads 113 and 123 exposed to the upper surface of the main fabric 111.

When the first separating sheet 112 is embroidered on the first embroidery object 110 in the following step S102, ethylene is compressed and returned to its original state to fix the first embroidery thread 113 more tightly. It is preferably made of vinyl acetate (EVA: Ethylene Vinyl Acetate).

EVA is a material with ductility and elasticity, and has an appearance density of 0.05j / cm 3 to 0.07j / cm 3, thermal conductivity of 0.03kcal / mh ° C to 0.05kcal / mh ° C, thermal shrinkage of 1% to 5%, and tensile strength of 5k. / Cm 2 to 15k / cm 2 and hardness of 300gf to 700gf, the first embroidery object 113 is more tightly arranged, even if no special cutter is used, the first embroidery object described later by a general cutter ( The cutting of 100) is preferred since it may not interfere with cutting.

2. First Embroidery Stage <S102>

Embroidery is made by passing the needle (n) of the embroidery machine into the interior of the first embroidery object 110, the first lower thread so that the first embroidery thread 113 is continuously hooked to the bottom of the main fabric 111 114 is embroidered at the same time.

That is, the first embroidery thread 113 is embroidered by passing from the upper surface of the first embroidery object 110 to the bottom surface, and at the same time the first embroidery thread 113 that passes the bottom surface of the first embroidery object 110 is first. Repeating the work to the lower thread 114 can be embroidered having a variety of patterns and shapes on the first embroidery object (110).

The first lower thread 114 may be a plywood coated with a low melting fiber in order to be fused by heat as in step S105, or the first lower thread 114 may be made of a low temperature fused yarn.

In addition, the low temperature fusion yarn may be a low temperature fusion polyester yarn (Low melting polyester company) or a low-temperature fusion polyester yarn containing yarn.

The low-temperature fusion polyester yarn is a melting point of 150 degrees to 180 degrees can be melted to each other without a separate adhesive even at a low temperature, do not use a separate adhesive may not cause environmental problems.

In addition, the first lower thread 114 does not damage the main fabric 111 even when heat is applied to the bottom surface of the main fabric 111, and at the same time, the first lower thread 114 is well adhered to the first embroidery thread 113. It is preferably made of 100% polyester material which is fused and melted at a temperature of 140 ° C to 200 ° C to be fixed to the main fabric 111.

3. Preparation for the Second Embroidery <S103>

The second embroidery sheet 120 is prepared by stacking the second separation sheet 122 having a predetermined thickness on the upper surface of the first embroidery object 110 embroidered in step S102.

Here, the second separating sheet 122 serves to maintain the three-dimensional embroidery pattern formed by the second embroidery thread 123 to be embroidered, the thickness is 1mm to 2mm to increase the workability of step S104 It is preferable.

In addition, the second separating sheet 122 is not made by the special cutter as described above made of EVA to more firmly fix the second embroidery thread 123 to be embroidered on the second embroidery object 120 in step S104. It is preferable because the second embroidery object may not be prevented from being cut even by a general cutter.

4. Second Embroidery Step <S104>

While embroidering by passing the needle n of the embroidery machine into the inside of the second embroidery object 120 to interfere with the embroidery in step S102, the second embroidery thread 123 is hung continuously on the bottom of the main fabric 111. The second lower thread 124 is simultaneously embroidered so that it can be twisted.

The second lower thread 124 is made of the same material as the first lower thread 114 as described in step S102, it is possible to embroider up to 600 stitches / cm2 by steps S102 and S104.

As described above, as the embroidery proceeds to the first embroidery in step S102 and the second embroidery in step S104, high density embroidery is possible without being entangled with each other even if it is long in the longitudinal direction, thereby increasing the three-dimensional feeling and aesthetic effect. Therefore, there is an advantage that can improve the quality of the product.

In addition, as the conventional general embroidery machine as described above can be embroidered with high density, it is possible to manufacture a good quality product.

5. Embroidery thread fixing step <S105>

The bottom surface of the main fabric 111 is heated so that the first and second lower threads 114 and 124 are fused at a low temperature so that the first and second embroidery threads 113 and 123 are not separated from the second embroidery object 120. .

That is, the first and second lower threads 114 and 124 melt at a predetermined temperature by heat, and serve to fix the first and second embroidery threads 113 and 123 to the main fabric 111.

For this reason, in the related art, as the cutting process is performed secondarily, an increase in work time and workability deteriorate, thereby increasing the overall manufacturing cost. However, according to an embodiment of the present invention, this problem may be solved.

6. Cutting length adjusting step <S106>

In the step of adjusting the length of the upper portion of the second embroidery object 120 is cut, by adjusting the height of the separate cutter (c) to adjust the cut length (l) of the second embroidery object (120).

For this reason, in the past, there was an inconvenience of adjusting the length of the embroidery exposed to the upper surface of the main fabric by the number of the separation sheets to be laminated, but in the three-dimensional embroidery method of the present invention, the operator adjusts the height of the cutter (c). By cutting the upper portion of the second embroidery object 120 as much, there is an advantage that the length of the embroidery can be adjusted according to the use.

7. Cutting sheet for separation <S107>

In the step S106, the upper part of the second embroidery object 120 (the upper part of the first separating sheet 112) is cut.

8. Removing sheet for separation <S108>

The upper part of the first separating sheet 112 is cut to expose a part of the first and second embroidery threads 113 and 123 to the upper surface of the main fabric 111, and the remaining part is the main fabric 111. By removing from the upper surface of the portion of the first and second embroidery threads 113, 123 to form a three-dimensional embroidery protruding to the upper surface of the main fabric (111).
