Description

TECHNICAL FIELD [0001] The present invention relates to a sewing hole finishing device, a finishing method, and a textile product of the same.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sewing hole finishing of a bedding, and more particularly to a technique for effectively blocking a sewing hole of an acupuncture bed so that an allergen such as dust or feces of a house dust mite can not pass therethrough.

When making bedding of various kinds of duvets and pads, the three sides of the duvets having pattern and shape are first stitched to make a bag shape, then the inside of the cotton is filled and the remaining openings are sewn to finish.

However, the body of the house dust mite accumulated in the inside of the bedding is discharged to the outside through the sewing hole formed by the sewing line passing through the fabric of the bedding, thereby providing a cause of allergy.

For this purpose, high density fabrics which can block allergens with normal bedding fabrics, such as fabrics having an average pore size of 10 m or less, can be produced. However, although the passage of the allergen through the bedding fabric itself can be blocked, there is a problem that the passage of the allergen through the stitching hole caused by the sewing applied to the bedding fabric can not be blocked.

In order to solve this problem, the present inventors have disclosed a method of sewing a bedding fabric using a sewing thread made up of a fiber core and a thermoplastic adhesive layer applied to the outer surface of the fiber core, in Patent Publication No. 2015-0117241; Attaching a release sheet to upper and lower surfaces of the bedding fabric, respectively; And passing the bedding fabric between a pair of opposing heat rollers.

When the bedding fabric passes between the heat rollers, the fused yarn of the stitched yarn melts and spreads to fill the gap between the yarn and the stitch hole.

However, this conventional method has the following problems.

First, by the heating by the heat roller, the fused yarn melts and becomes a liquid having viscoelasticity and spreads by pressing with the heat roller, thereby filling the gap between the thread and the sewing hole. Since the viscoelastic liquid does not spread uniformly and reliably, There is a problem that a gap between the holes can not be filled.

In this case, the dirt and the dead body of the house dust mite existing in the bedding through the gap that can not be naturally leaked out to cause allergic to the bedding user.

Second, a heat press and a heating plate may be used instead of the heat roller. However, when the heating plate is pressed for a long period of time, the heating plate may be warped or the heating plate may be warped Which may result in a portion that is not uniformly pressurized by the press over the entire length of the heating plate, or that is not pressurized or contacted by the press. As a result, there is a blocking part along with a stitch hole and a non-blocking part, which reduces reliability.

Therefore, an object of the present invention is to reliably prevent the sewing holes by sewing as a whole.

Another object of the present invention is to reliably prevent the sewing hole even if the pressing by the press is not uniform due to long use.

The above object is accomplished by a sewing machine comprising: a main body having a control unit for finishing a sewing hole formed on a sewn portion of a sewn using a core composed of a core and a fused yarn for wrapping the core in a coil shape; A cylinder unit installed at an upper portion of the main body and driven and controlled by the control unit; A press coupled to the cylinder unit and lifted and lowered and having a heater built therein; A heating plate fixed to the main body so as to face the press and having a heater and a temperature sensor built therein; And a vibration unit coupled to the heating plate and driven and controlled by the control unit to vibrate the heating plate, wherein the viscoelastic liquid, in which the fusion yarn is melted by the press and the heating plate by the heating plate, And the stitch hole finishing apparatus is characterized in that the stitch hole finishing apparatus closes a gap between the core and the stitch hole by pressing and vibration by the vibration unit.

Preferably, the vibration unit is coupled to both ends of the heating plate, and the heating plate may be vibrated in the longitudinal direction and / or the width direction.

Preferably, the vibration unit may be a vibration motor having an eccentric wheel mounted on a motor shaft and fixed to a lower surface of the heating plate.

The above object can be accomplished by a method of finishing a sewing hole formed in a sewing fabric portion using a yarn made up of a core and a fused yarn wrapping the core in a coil shape and thermally pressing the upper and lower surfaces of the fabric portion; Oscillating the fabric part in a horizontal direction in a pressing process; And cooling the fabric part, wherein the viscoelastic liquid formed by melting the fused yarn by the thermocompression is cooled in a state in which the gap between the core and the sewing hole is blocked by the pressurization and the vibration And the sewing hole is blocked by the sewing hole finishing method.

The above object is achieved by a process for sewing a fabric by sewing a fabric using a fabric composed of a core and a fused yarn for wrapping the core in the form of a coil and thermally compressing the upper and lower surfaces of the fabric portion formed by the sewing, Wherein the viscoelastic liquid is formed by melting the fused yarn by the thermo-compression bonding, and the viscoelastic liquid, which is formed by the thermo-compression bonding, Wherein the cooling is performed in a state in which a gap between the core and the sewing hole is blocked by vibration, so that the sewing hole is blocked.

According to the above-described configuration, it is possible to reliably prevent the sewing holes by the sewing, and the excrement or the dead body of the house dust mites present inside the bedding can be prevented from being caused to leak to the outside and causing allergies to the bedding user.

Further, even if the press is unevenly pressed or brought into contact with the press by a long use, the viscoelastic liquid flows by the vibration, thereby making it possible to reliably prevent the sewing hole.

Further, since the structure for applying the vibration unit is simple and the manufacturing cost is low, the installation cost can be reduced.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view showing a yarn used for sewing. Fig.

The yarn 10 is composed of a core 11 composed of a normal yarn and a melting fiber 12 wound around the core 11.

The core 11 may include both spun yarns or filament yarns made by twisting single fibers or short fibers.

The fusing yarn 12 is composed of only low melting point PET and melts when heat is applied. It has a melting point of about 80 ° C to 140 ° C and may have a thickness of about 70 to 140 De (denier), but is not limited thereto.

After the stitches 10 are stapled together and thermocompression is performed within the melting temperature range of the fusing yarn 12, the fusible yarn 12 melts to become a viscoelastic liquid having both viscosity and elasticity, So that it plays a supporting role.

Fig. 2 shows a sewing hole finishing apparatus according to the present invention.

A bracket 110 is installed on the upper part of the main body 100 and a cylinder unit 120 is coupled to the bracket 110. Guide rods 130 are installed on both sides of the cylinder unit 120.

The press 140 is coupled to the rod 122 of the cylinder unit 120 and the end of the guide rod 130. The press 140 has a flat plate shape having a narrow width and a long length and has a heater built therein .

When the cylinder 121 is operated by pneumatic or hydraulic pressure, the rod 122 is lowered or raised so that the press 140 descends or rises and the guide rod 130 does not shake the press 140 when the guide rod 130 ascends or descends. Guide.

A heating plate 150 is installed on the main body 100 in opposition to the press 140. The heating plate 150 has the same shape as the press 140 and has a heat wire and a temperature sensor built therein.

A vibrating unit 160 is installed at both ends of the longitudinal direction of the heating plate 150 to vibrate the heating plate 150 at a predetermined speed.

Various types of vibrating units 160 may be used. In this embodiment, a vibration motor provided with an eccentric wheel on the motor shaft is fixed to the both ends of the heating plate 150.

When the vibration motor is driven to rotate the motor shaft, the eccentric wheel coupled to the motor shaft rotates to generate vibration, so that the heating plate 150 can vibrate in the longitudinal or width direction or vibrate alternately in both directions.

Unlike this embodiment, a rotary motor that repeats clockwise and counterclockwise at a constant rotation angle can be applied as the vibration unit 160. [ That is, both ends of the heating plate 150 are coupled to the rotating shaft so that the rotating motor rotates clockwise and counterclockwise repeatedly at a constant rotation angle, whereby the heating plate 150 repeatedly rotates clockwise and counterclockwise .

Hereinafter, the operation of the sewing hole finishing apparatus according to the present invention will be described with reference to Figs.

Fig. 3 shows a state in which the gap of the sewing hole is clogged with respect to the conventional one.

The control unit 200 of the main body 100 controls the cylinder unit 120 to lower the rod 122 by placing the sewing finished portion of the fabric 50 on the heating plate 150 and driving the sewing hole finishing apparatus .

As a result, the press 140 coupled to the end of the rod 122 descends and contacts the heating plate 150 to press the heating plate 150 at a predetermined pressure.

The control unit 200 controls the vibration unit 160 to vibrate at a predetermined speed so that the heating plate 150 coupled thereto is pressed by the press 140 as the vibration unit 160 vibrates Vibrates.

As a result, the raw material is heated by the press 140 and the heating plate 150 while the press 140 is pressed against the heating plate 150, and the fused yarn 12 ) Is melted and converted into viscoelastic liquid (14).

The viscoelastic liquid 14 flows in the sewing hole by the pressurization by the press 140, and as shown in Fig. 3 (a), a gap 52 is formed in a part without spreading uniformly.

At this time, when the heating plate 150 is vibrated by the vibration unit 160, the viscoelastic liquid 14 in the sewing hole flows uniformly in the sewing hole while the fabric is vibrated in the horizontal direction, , The gap between the core 11 and the stitch hole is clogged.

As a result, the stitches formed on the fabric by the stitch finishing can be reliably prevented by cooling the gap formed between the core 11 constituting the padding 10 and the stitch hole in a state in which both the viscoelastic liquid 14 are covered .

Table 1 below shows the results of experiments to cut house dust mites using sewn-finished fabric.

For the experiment, one hundred samples of house dust mites are placed in a sealed container with a feed of mites. One side of the sample box is blocked by the stitched part of the fabric, that is, the part where the stitch hole is formed.

Samples 1 to 3 are referred to as Samples 1 to 3 according to the used fabrics. Samples 1 and 2 are obtained by sewing the fabric after the sewing and without specially finishing the fabric, respectively. And the fabric is thermally compressed and then subjected to vibration treatment.

2 weeks 4 weeks 6 weeks Sample 1 30% 80% 98% Sample 2 One% 14% 35% Sample 3 0% 2% 4%

As shown in Table 1, most of the mites survived after 6 weeks in the case of the sample 1 which was not subjected to the special finishing after the sewing, and in the case of the sample 2 in which the fabric was heat-pressed after the sewing, Marie's tick survives.

On the other hand, in the case of Sample 3 in which the fabric was subjected to vibration after thermocompression, only four mites survived after 6 weeks, indicating that most of the mites did not pass through the fabric. In other words, the viscoelastic liquid formed by melting the fused yarn by the vibration process after thermocompression of the fabric reliably blocks the gap formed between the core of the yarn and the sewing hole by uniformly spreading the sewing hole.

As a result, it is possible to fundamentally prevent the excretion or carcass of the house dust mite from leaking out to cause the allergen to the bedding user.

Further, as described above, since the structure of applying the vibration unit is simple and the manufacturing cost is low, the installation cost can be reduced.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.
