Description

Needle for Embroidery

The present invention relates to an embroidery needle, and more specifically, an embroidery method in which a loop of thread is formed in the fabric by passing a thread through the hole while forming a hole in the fabric from one side of the fabric for embroidery and returning the thread through the hole again It relates to a needle used to pass a thread through the fabric while forming a hole in the fabric.

Embroidery is to display various patterns or figures by combining a pattern and color of a thread disposed on one surface of the fabric by fixing a thread to a fabric made of fabric or net.

In such embroidery, various methods are used to fix the thread to the fabric, and depending on the method, the form that can express or express a unique texture is changed, and the method of embroidery work is also changed.

As one of the embroidery methods, a technique of forming a loop of thread in the fabric by passing a thread through the hole while forming a hole in the fabric from one side of the fabric for embroidery and returning the thread through the hole is used.

U.S. Patent No. 4103631 (Document 1) and U.S. Patent No. 5117772 (Document 2), which disclose inventions related to needles used for embroidery in this way, also disclose such an embroidery technique. With reference to the invention and its drawings, the method of embroidery and the structure and action of needles that have been conventionally used for this embroidery will be described with reference to FIGS. 1 to 5 .

First, the structure of the needle 200 will be described with reference to FIG. 1, which is a longitudinal cross-sectional view showing the overall configuration of the needle 100 of Document 1, and FIGS. 2 and 5 showing enlarged parts of the configuration.

The needle penetrates the fabric (1 in FIG. 3) to form a hole in the fabric through which the thread 2 passes, and the needle body 210 for guiding the thread 1 to be fixed to the fabric 2 and a handle held by a person (220).

The needle body 210 and the handle 220 are coupled to each other in the longitudinal direction, both of which are formed in a substantially cylindrical shape and include a first guide hole 211 and a second guide hole 221 through which the thread 1 is guided. each is formed. The needle body 210 is inserted and coupled to the lower end of the handle 220 in the longitudinal direction, and the second guide hole 211 of the needle body is connected to the first guide hole 221 of the handle.

The thread 1 is sequentially guided from the skein to the first and second guide holes 221 and 211 through the hole 222 at the top of the handle, and is exposed to the outside through the tip 213 of the needle body 210, As shown in FIG. 5 , a circular third guide hole 214 is formed at the tip 213 of the needle body 210 in a direction perpendicular to the longitudinal direction of the needle body 210 so that the thread (1) is drawn out to the side of the needle body 210 through the third guide hole 214 .

The tip 213 of the needle body is in the form of an oblique cut to form a sharp tip.

An embroidery method in a state in which the thread 1 is inserted into the needle 200 will be described with reference to FIG. 3 .

When a hole is made in the fabric 2 with the tip 213 of the needle body formed sharply and the needle body 210 is penetrated through the fabric 2, the thread 1 also cuts the fabric 2 together with the needle body 210. It penetrates and is placed on the back side, and when the needle body 210 is pulled out again to come out above the upper surface of the fabric 2, the thread 1 is released from the needle body 210 to form a loop on the back surface of the fabric 2 will form

With the needle body 210 removed from the fabric 2, the needle body 210 is moved in a direction parallel to the surface of the fabric 2 as indicated by arrow F in FIG. 3, and the previous operation is repeated again. do.

By this series of operations, a loop is continuously formed on the back surface of the fabric 2 , and the thread 1 forms a pattern on the upper surface of the fabric according to the movement direction of the needle body 210 . The thread 1 overlaps each other in the hole of the fabric 2 formed through the needle body 210 and is fixed by the frictional force between the fabric 2 and the thread 1 .

In order to perform such embroidery, the operation of inserting the thread 1 into the guide holes of the needle 200 in the state shown in FIG. 1 must be preceded.

Such a working method will be described with reference to FIGS. 4 and 5 .

First, referring to FIG. 4 , as a tool for inserting the thread 1 into the needle 200 , a wire 3 for insertion is provided. The wire for insertion (3) is formed by overlapping the spring steel, and the tip (4) is formed in a form that can be opened.

The tip 4 of the wire for insertion 3 is inserted from the tip 213 of the needle 200, exposed to the outside through the hole 222 of the handle, and the thread 1 is inserted into the tip 4 of the wire for insertion ) through it. This state is shown in FIG. 4 .

When the wire for insertion 3 is retracted from the state shown in FIG. 4, the tip 4 moves along the first and second guide holes 221 and 211 of the wire and exits to the tip 213 of the needle body. .

At this time, the thread 1 also comes out from the tip 213 of the needle body 210 while being caught on the tip 4 of the wire for insertion, and the thread 1 is removed from the first and second needles from the skein. It extends along the guide holes 221 and 211, and the tip of the thread 1 is exposed to the outside from the tip 213 of the needle body. This state is shown in FIG. 5 .

In the state shown in FIG. 5 , the insertion wire 3 is inserted into the tip 213 through the third guide hole 214 formed at the tip of the needle body 110 from the outside, and the thread 2 is The tip is passed through the tip of the wire 3 for insertion.

When the wire for insertion 3 is pulled in this state, the tip of the thread 1 is placed outside the tip 213 of the needle body along the third guide hole 114 . Such a state is the state shown in FIG. 1 .

This completes the operation of arranging the thread 1 on the needle 200 for embroidery.

As described above, for the needle of Document 1 or Document 2, an insertion wire must be used to place the thread on the needle, and in particular, the operation of passing the thread from the end of the handle to the needle body using the insertion wire primarily After that, it should be passed through the guide hole at the tip of the needle body again using the wire for insertion.

As such, in the conventional embroidery, it is necessary to perform a cumbersome operation of several steps using a separate tool in order to arrange the thread on the needle. In particular, in order to change the thread to form a pattern by changing the type or color of the thread, such cumbersome work must be continued, which makes the work inconvenient in embroidery, which is easy to operate compared to other embroidery techniques.

In order to solve this problem, Korean Patent Publication No. 10-1917372 (Document 3) invented and filed by the applicant of this application discloses a needle for embroidery of a new configuration.

The needle for embroidery according to the invention of Document 3 is composed of a needle body that forms a hole in the fabric for embroidery, through which the thread passes, and guides the thread to be fixed to the fabric, and a handle held by a person.

In the embroidery needle according to the invention of Document 3, in the handle and the needle body, first guide holes and second guide holes serving as guide passages for threads are formed therein, respectively, in the longitudinal direction, and the needle body has a first end in the longitudinal direction. Is inserted into one end of the first guide hole of the handle is coupled in a line with the handle in the longitudinal direction, the second end opposite the first end is formed as a tip to form a hole in the distal end, the needle body at the second end A third guide hole penetrating outward in a direction perpendicular to the longitudinal direction of the needle body and a third guide hole through which the thread is guided outward from the second guide hole is formed, and the needle body and the handle have first guide holes and a first guide hole along the length direction of the handle, respectively. A first opening and a second opening through which the second guide hole is opened to the outside are formed in a line with each other, and in the first opening and the second opening, the seal can be inserted or separated between the outside and the first and second guide holes. It is formed with a certain width, and the second opening is provided in a direction opposite to the third guide hole.

In the needle according to the invention of Document 3, when the embroidery thread is placed on the needle, the tip of the thread is first passed through the third guide hole of the needle body, and then the rest of the thread is inserted into the second opening of the needle body and the handle. After arranging the needle along the first opening in the longitudinal direction, it is inserted into the first opening from the end side of the handle and the tip of the thread is pulled, so that the thread becomes a guide passage for the thread through the first and second openings. and the second guide hole.

As described above, in the needle according to the invention of Document 3, since the arrangement of the embroidery thread is made very simply, the arrangement and replacement of the thread can be made easily.

In the needle according to the invention of Document 3, guide holes are formed in a line from the needle body to the end of the handle, so that when the thickness of the thread or the frictional force on the surface is sufficiently large, the thread does not come off the needle during embroidery work .

However, when the thickness of the thread is thin or the frictional force on the surface is small, the embroidery thread is separated from the guide hole continuously formed on the handle and the needle body, so there is a problem in that the embroidery work is not performed smoothly.

Document 1: US Patent No. 4103631 Document 2: US Patent No. 5117772 Document 3: Korean Patent Publication No. 10-1917372

An object of the present invention is to provide a needle for embroidery that forms a hole in the fabric through which a thread passes in embroidery and guides the thread to be inserted and fixed through the hole.

Specifically, an object of the present invention is to provide an embroidery needle having a configuration in which the operation of arranging a thread on a needle for an embroidery operation can be performed simply and there is no fear that the thread is separated from the needle during the embroidery operation.

In addition, the present invention is to provide a needle for embroidery having a configuration that can smoothly pass through a densely woven fabric.

The object of this invention mentioned above is achieved by the needle for embroidery of this invention used for embroidery,

The needle for embroidery of this invention is

It is composed of a needle body that forms a hole in the fabric for embroidery and allows the thread to pass through the fabric to be fixed, and a handle held by a person, wherein the handle and the needle body are integrally formed continuously in the longitudinal direction with each other, , First and second accommodating spaces in which a thread is arranged and accommodated are continuously formed with each other, and a first hole through which the thread is inserted into the first accommodating space from the outside is formed at the rear end of the handle in the longitudinal direction, the needle A second hole through which the thread is drawn out into the second accommodating space is formed at the longitudinal end of the main body, and the handle and the needle body have first and second slots penetrating between the first and second accommodating spaces and the outside, respectively. are formed respectively, and the first slot and the second slot are continuously formed with each other.

When embroidering work with the embroidery needle of this invention, the embroidery thread must first be inserted into the embroidery needle and arranged.

The tip of the embroidery thread is passed through the first hole of the handle from the outside of the embroidery needle toward the first receiving space of the handle, and then the tip of the embroidery thread is directed outward from the second receiving space of the needle body to remove the needle body. 2 through the hole.

Accordingly, the embroidery thread passes through the first hole from the outside and is drawn out through the second hole again, and is not disposed in the first and second accommodating spaces of the handle and the needle body.

Then, when a tensile force is applied by pulling both sides of the embroidery thread from the outside of the embroidery needle, the thread is disposed in the first and second accommodating spaces of the handle and the needle body through the first and second slots. As a result, the embroidery thread is placed on the embroidery needle and the embroidery operation can be started.

Even when the diameter of the embroidery thread is smaller than the width of the first and second slots during embroidery work, the embroidery thread is inserted into the receiving space through the first hole from the outside, so that it does not escape through the first and second slots. .

As described above, in the embroidery needle of the present invention, the operation of arranging the thread is very simple, and there is no fear that the embroidery thread is separated from the receiving space of the needle during the embroidery operation.

As an additional feature of the present invention, the embroidery needle of the present invention comprises:

At the rear end of the handle in the longitudinal direction opposite to the portion in the diameter direction of the portion where the first hole is formed, the first slot is extended to provide a first opening in which the first accommodating space is opened to the outside,

A second opening in the radial direction opposite to the portion in which the second hole is formed at the longitudinal tip of the needle body may be provided with a second opening in which the second receiving space is opened to the outside by expanding the second slot.

According to this configuration, when arranging the thread on the embroidery needle, the tip of the thread can be pulled through the first opening provided facing the first hole to pass through the first hole, and the tip of the thread can be removed through the second opening. Since it can be passed through two holes, the thread can be placed on the embroidery needle without the need for a separate tool.

As a further feature of the present invention, in the embroidery needle according to the present invention,

The needle body consists of a flat bottom surface, two flat side surfaces extending vertically from both ends in the width direction of the bottom surface, and two upper surfaces extending to face each other from each side, and the ends of the two top surfaces are spaced apart from each other to form a second slot , and the second hole may be configured to be formed on the bottom surface.

According to this configuration, the needle body has a high contact pressure with the fabric, and the bottom surface on which the second hole is formed and the side surfaces on both sides of the bottom surface are formed as flat surfaces, so that the needle body is self-contained even when an embroidery fabric with a high fiber density is used. It can penetrate the receiving fabric smoothly.

In addition, since the second hole is formed on the flat bottom surface to form the shape of the second hole through which the yarn passes as intended, friction when the yarn passes through the second hole can be minimized.

In addition, it is preferable that the longitudinal tip of the needle body has an inclined surface formed from the curved surface toward the bottom to form a tip. Accordingly, friction is minimized when the needle body penetrates the fabric for embroidery.

As an additional feature of the present invention, the surface of the handle in the embroidery needle of the present invention may be formed of a plurality of curved surfaces continuous with each other without the centers of curvature coincide with each other.

When the surface of the handle is formed as a curved surface, the user feels good in the hand and feels less fatigue when holding and embroidering work, but the embroidery needle rolls on a flat surface and may be out of place.

However, in the embroidery needle according to an additional feature of the present invention, since the curved surfaces forming the surface of the handle do not coincide with each other in the center of curvature, it rotates even on a flat surface and does not deviate from the seat, and is gripped even by touch when gripped by the user. posture is known. In addition, since the curved surfaces are continuous with each other, the user can perform embroidery work for a long time without giving the user an unpleasant and uncomfortable touch.

As an embodiment of the needle for embroidery according to these additional features,

The cross-section of the handle is made in a form in which two arcs having an angle smaller than 180 degrees are connected to each other, and the first slot may be configured to be formed in the center of any one of the two arcs.

In addition, since the portion where the two arcs in the handle is in contact with the handle changes the curvature abruptly or is formed as a discontinuous surface, the user can grasp the posture of the handle when the user grips the handle by tactile sense. You will be able to hold it in an appropriate position.

In particular, when the portion where the two arcs of the handle are in contact with a curved surface having a smaller curvature than the arc, the portion in contact with the arc is clearly grasped by the user's tactile sense and gives the user an unpleasant tactile feel.

Hereinafter, as specific details for carrying out the present invention, the configuration and operation of an embroidery needle according to an embodiment of the present invention will be described.

First, the overall configuration of the needle of this embodiment will be described with reference to FIG. 6 .

The needle of this embodiment is integrally formed with a needle body 20 that forms a hole in the fabric for embroidery and guides the thread to be fixed to the fabric, and a handle 10 that is gripped by a person in the embroidery work.

The needle body 20 and the handle 10 are each elongated as a whole, have longitudinal axes parallel to each other, and the needle body 10 is continuously extended in the longitudinal direction from the handle 20 .

Referring to FIG. 9 showing a cross-section of the handle 10, the handle has a first accommodating space 11 in which the thread 1 is placed by bending one flat metal panel, and the handle 10 is The widthwise ends of the forming metal panel are spaced apart from each other to form a first slot 12 through which the thread 1 can pass. The first slot 12 is also continuously formed along the longitudinal direction in which the handle 10 extends.

The handle 10 has a shape in which first and second arcs 101 and 102 having a radius of curvature R face each other inward. Each of the arcs 101 and 102 is composed of an arc with an angle smaller than a semicircle, that is, an angle smaller than 180 degrees, so that the portion 103 where the arcs are in contact with each other is a curved surface having a curvature smaller than that of the arcs 101 and 102. consist of. Further, the first slot 12 is formed in the center of the first arc 101 .

According to this configuration, the handle 10 does not form a cylindrical shape as a whole, but has a shape in which two arcs 101 and 102 having a radius of curvature greater than the minimum width of the handle are glued together. Accordingly, when the needle is placed on a flat surface, the needle does not rotate due to the shape of the handle 10 and remains in place.

In addition, when the user grips the handle 10, the portion 103 in contact with the two arcs 101 and 102 has a small curvature, so it is sensed as a protruding portion in the user's hand. Accordingly, the user recognizes the posture in which he or she holds the handle 10 through the touch of the hand.

Referring to FIG. 10 together with FIG. 6 , at the rear end 15 in the longitudinal direction of the handle 10 and the opposite end of the needle body 20 , the thread 1 is inserted into the first receiving space 12 from the outside. One hole 13 is formed.

The first hole 13 is positioned opposite to the first slot 12 , that is, the first slot 12 is located at the center of the first arc 101 , and the first hole 13 is located at the position of the second arc 102 . formed in a central position.

The first arc 101 opposite to the radial direction of the second arc 102 in which the first hole 13 is formed at the rear end 15 in the longitudinal direction of the handle 10 has the first slot 12 extended toward the rear end. The first accommodating space is a first opening 105 that opens to the outside.

Accordingly, the portion in which the first hole 13 is provided in the first accommodating space 11 of the handle becomes an open space without the first arc 101 constituting the handle 10 , and the first hole 13 from the outside ) to insert the thread 1 into the first accommodating space 11 , the user can grip and pull the tip of the thread 1 that has passed through the first hole 13 .

A needle body 20 is integrally formed with the handle 10 on the front end side of the handle 10 in the longitudinal direction.

The needle body 20 has a smaller diameter than the handle 10 since the thread 1 is inserted through the fabric for embroidery. Accordingly, the front end side of the handle 10 adjacent to the needle body 20 forms the transition portion 14 having a smaller diameter.

As the first slot 12 is expanded, the first arc 101 in which the first slot 12 is formed in the handle 10 disappears, and the diameter of the opposite second arc 102 is increased. It has a shape forming the needle body 20 as it becomes smaller.

Referring to FIG. 8 showing a cross-section of the needle body 20 together with FIG. 6 , the needle body 20 bends a metal plate to form a second accommodation space 21 in which the thread 1 is accommodated, and , the width direction ends of the metal plate face each other to form the second slot (22).

The second slot 22 extends along the length direction of the needle body 20 and is formed at the same circumferential position as the first slot 12 of the handle, so that the first slot 12 when viewed in the plan view of FIG. 6 . And the second slot 22 is placed on a straight line.

In addition, since the open portion of the transition portion 14 is placed between the first slot 12 and the second slot 22, the first and second slots 12 and 22 are continuously formed.

The needle body 20 is a flat bottom surface 201 extending from the second arc 102 in which the first hole 13 is formed in the handle 10, and is formed vertically from both sides in the width direction of the bottom surface. It consists of a flat side surface 202, two upper surfaces 203 extending from each side to a curved surface and covering a second receiving space 21 surrounded by a bottom surface and a side surface.

Further, the upper surfaces 203 are spaced apart from each other at their free ends to form a second slot 22 therebetween. The upper surfaces 203 are formed as curved surfaces having a curvature, and the side surfaces 202 are connected to each other by a curved surface smaller than the curvature of the upper surface.

In this embodiment, the upper surfaces 203 are formed in a curved surface, but may be formed in a flat surface rather than a curved surface, and in particular, the tip of the needle body 20 has a cross-section close to a rectangle as a whole despite including a curved surface.

The structure of the tip 24 of the needle body will be described with reference to FIGS. 7, 10 and 11 together with FIG. 1 .

The tip 24 in the longitudinal direction of the needle body 20 forms a tip inserted by making a gap in the fabric for embroidery.

A second hole 23 through which a thread passes is formed in the bottom surface 201 of the tip 24 , and the second slot 22 is expanded on the opposite side in the diametric direction from the position of the second hole 23 to the upper surface 203 . ) is gradually disappeared and the side 202 is also gradually lost, so that only a part of the bottom surface 201 remains at the position of the frontmost end in the longitudinal direction of the needle body.

Accordingly, the opposite side of the position where the second hole 23 of the bottom surface 201 is formed in the front end 24 forms an opening through which the second accommodation space 21 is opened to the outside. Due to the partial opening of the second accommodating space 21 , the seal 1 can be disposed through the second hole 23 toward the outside from the second accommodating space 21 .

In addition, as shown in FIG. 11 , the needle body 20 forms an inclined surface 204 as a whole from the position of the second slot 22 to the most front end of the bottom surface 201 , and as shown in FIG. 10 , the needle The bottom surface 201 of the main body forms an acute angle at the front end, so that the front end 24 of the needle body forms a tip advantageous for penetrating the fabric for embroidery.

The needle for embroidery of this embodiment of the configuration described above is made of a single metal plate such as stainless steel.

After cutting the metal plate according to the profile when the needle for embroidery of this embodiment is deployed in a plane, the metal plate is bent by plastic processing such as sheet metal or forging, and the first hole 13 and the second hole 23 are formed. It is formed by drilling or the like to manufacture needles for embroidery. can

The needle for embroidery of the present invention can be manufactured integrally by the above method, but the fact that the needle body and the handle are integral does not mean that it is formed by plastically processing a single metal plate.

The needle body and the handle may be manufactured, respectively, and they may be coupled to each other by welding or interference fit, or may be formed by casting a metal material by a die-casting technique, or may be manufactured by injection molding a synthetic resin.

However, in this invention, the fact that the handle and the needle body are integral means that they are coupled to each other without needing to be separated from each other for insertion of a thread during use, and can be structurally integrally formed.

A method of inserting the thread 1 so as to embroider the fabric with the embroidery needle of this embodiment will be described with reference to FIGS. 13 to 15 .

Fig. 15 shows a state in which the thread 1 is inserted into the needle for embroidery of this embodiment and embroidery can be performed.

The thread is inserted into the first accommodating space 11 in the handle 10 from the outside through the first hole 13 and extends along the first accommodating space to the second accommodating space 21 of the needle body 20, and is drawn out through the second hole 23 at the tip of the needle body.

By using the needle for embroidery on which the thread is arranged in this way, the embroidery work can be performed in the same manner as the method of using the needle for embroidery of the prior art described with reference to FIG. 3 in the description of the background art.

13 shows a state in which the thread 1 is passed through the first hole 13 .

The front end of the thread 1 is inserted into the first accommodating space 11 of the handle from the outside, and the opposite side of the first hole 12 at the rear end 15 of the handle has the accommodating space 11 open to the outside, so the user Put your hand on the rear end (15) of the handle and pull the tip of the thread (1).

The tip of the pulled thread 1 is not disposed in the receiving space of the handle 10 and the needle body 20 but is exposed to the outside.

The tip of the thread 1 pulled in this way is passed through the second hole 23 .

Since the second accommodating space 21 is open to the outside at the tip 24 of the needle body opposite to the second hole 23, the user grips the thread 1 by hand to outward the thread 1 from the accommodating space. ) through it.

Accordingly, as shown in FIG. 12 , the thread 1 penetrates the first hole 13 from the outside and enters the receiving space of the handle 10 , and then through the second hole 23 again the needle body ( 20) is in a state withdrawn to the outside opposite to the accommodation space, and between the first hole 13 and the second hole 23, the seal 1 is not placed in the accommodation spaces 11 and 21.

In this state, a tensile force is applied by gripping and pulling the thread 1 from both sides of the outer side of the first hole 13 and the outer side of the second hole 23 .

Due to this tension, the thread is taut and tends to be straight, the open portion of the rear end of the handle 15 is continuous with the first slot 12, and the open portion of the front end of the needle body 24 is connected to the second slot 22 ), and the first slot 12 and the second slot 22 form a straight line with the open portion of the transition part 15 therebetween, so that the thread 1 is formed between the first slot 12 and the second slot. It is placed in the inside of the handle 10 and the needle body 20, that is, the first and second accommodating spaces 11 and 21 through the second slot 22.

In this way, the thread 1 is in a state in which the embroidery work shown in FIG. 13 is possible.

This thread insertion operation is a very simple operation of sequentially penetrating the tip of the thread 1 through the first hole 13 and the second hole 23 and pulling both sides to apply a tensile force. Therefore, it becomes very simple to insert the thread 1 into the needle for embroidery.

Since the first hole 13 and the first slot 12 of the handle and the second slot 22 of the needle body are intended to place the thread 1 in the receiving space, they are formed to have a diameter and a width larger than the diameter of the thread. In particular, it is advantageous to have a sufficiently large diameter and a sufficiently wide width compared to the diameter of the yarn so that the insertion and disposition of the yarn can be performed smoothly.

During the embroidery work, the needle for embroidery generally fluctuates in a vertical state and an inclined state, and the thread 1 placed in the receiving spaces 11 and 21 by this fluctuation causes the first slot 12 and the second slot 22 ) through which the force is drawn to the outside.

However, since the thread 1 is unwound from the skein and passes through the first hole 12 and is placed in the receiving spaces 11 and 21 , a part of the thread 1 may be removed from the first slot 12 or the second slot 22 . Although it can be placed in a state drawn out through the accommodating space, the entire chamber 1 is separated from the receiving space and it does not occur.

Meanwhile, in the embroidery needle of this embodiment, the tip 24 of the needle body penetrating the fabric for embroidery is formed in a rectangular cross-section as a whole, and the second hole 23 through which the thread passes is formed on a flat surface.

The tip of the needle for embroidery as disclosed in Documents 1 and 2 has a circular cross section, and the tip of the needle for embroidery disclosed in Document 3 has a triangular cross section. A needle having such a tip shape is not a problem when used for a fabric for embroidery with a sparse structure, but is a problem when used for a fabric with a narrow spacing between woven fibers, that is, a fabric with a tight configuration.

Since the fabric is woven in such a way that warp and weft yarns intersect, the space surrounding the warp and weft yarns is approximately rectangular, but when the cross section of the tip of the needle is circular or triangular, the surface of the tip of the needle gets caught in the warp or weft yarns forming the fabric, causing great friction. It is subjected to impact and resistance that causes warp or cuts the unit fibers forming the warp or weft. Therefore, when penetrating the fabric with the tip of the needle in the embroidery work, shock and large resistance are generated, which becomes an obstacle to the embroidery work, and the user who performs the embroidery work uses excessive force.

However, in the embroidery needle of this embodiment, since the cross section of the tip of the needle in contact with the fiber of the fabric for embroidery is generally rectangular, each surface of the tip is in line contact with the fiber over a wide length, thereby reducing friction between the needle and the fiber. Not only is it small, but the surface of the needle tip cuts the unit fibers sharply, so that no impact is applied in the embroidery work and the user does not repeatedly apply excessive force.

In addition, since the second hole 23 at the tip of the needle body that allows the thread 1 to pass through the fabric is formed on the flat bottom surface, the shape of the hole is the intended shape by processing, preferably, the circular shape is maintained like the cross section of the thread. As a result, the seal 1 passes through the second hole 23 smoothly and friction is reduced.

As described above, the configuration and operation of the needle for embroidery according to the embodiment of the present invention and the embroidery operation using the same have been described. However, the present invention is not limited to this embodiment, and changes in various configurations and addition of elements within the scope of the claims are not limited thereto. is possible
