Abstract

A sewing thread is characterized in that it comprises a fiber core and a thermoplastic adhesive layer applied to the outer surface of the fiber core. Even if a logo or decorative pattern is attached to a bedding or a tent or sewing is performed by embroidery, the sewing hole formed by the sewing can be completely filled with the adhesive.

Description

TECHNICAL FIELD [0001] The present invention relates to a sewing thread for sewing a sewing hole and a manufacturing method of a textile product using the same. BACKGROUND OF THE INVENTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a sewing thread, and more particularly, to a sewing thread and a method of manufacturing a fiber product using the sewing thread to prevent a gap from being formed by filling sewing holes formed by sewing.

In general, products such as clothing, bedding or tent are designed by the designer, and after preparing the necessary fabric and auxiliary materials, the fabric is cut according to a certain pattern, and the separated pieces of cloth are stitched together through the sewing process using the thread, And attaching a subsidiary material such as a button or a zipper thereto.

In this process, the thread penetrates through the cloth to form a sewing hole, and this sewing hole causes various problems.

First, in the case of mountain climbing equipment such as a tent, wind or moisture can penetrate through a sewing hole formed by sewing cloth pieces against each other while making a tent. To solve this problem, a seam sealing tape is put on the sewing line and attached by applying heat to the iron.

However, after a certain period of time, the ventricular ring tape is peeled off, and the portion with weak adhesive strength is exposed, resulting in dirtiness and re-repair.

In addition, in the case of bedding, the carcass mites accumulated in the interior of the bedding are discharged to the outside through sewing holes formed by sewing or attaching a decorative material for decorating, and thereby causing a cause of allergy . Specifically, the excrement or carcass of the house dust mite is allergen which is an allergen causing allergy, that is, a powder constituting a rotten protein. Since the size is 3 to 50 탆 or so, it flows out from the inside of the bedding through the needle hole . Of course, although the yarn itself fills the sewing hole to some extent, it flows out through the gap formed between the yarn and the sewing hole.

Accordingly, it is an object of the present invention to provide a removable sewing thread that can simply fill a sewing hole formed by sewing.

It is another object of the present invention to provide a method of manufacturing a fiber product in which a sewing hole formed by sewing is filled in a fiber product to prevent a gap from being created.

The above object is achieved by a thermoplastic resin composition comprising a fiber core and a thermoplastic adhesive layer applied to the outer surface of the fiber core, wherein the sewing hole is filled by melting of the adhesive constituting the adhesive layer at a preset temperature and pressure And a sewing thread for sewing.

Preferably, the adhesive of the adhesive layer may be an amide-based adhesive or a polyethylene adhesive.

The above object may be achieved by a sewing machine comprising: sewing a fabric using the sewing thread; And passing the fabric between a pair of heat rollers disposed opposite to each other, wherein in the step of passing the fabric, the heat roller is configured to move the fabric at a temperature above the melting temperature of the adhesive of the adhesive layer And the fibers are pressed while being heated.

Preferably, the fabric may be a fabric applied to a bedclothes or an outdoor clothing / tent.

According to the above configuration, even if the logo or the decorative pattern is attached to the bedding or the tent or the embroidery is placed to increase the esthetics of the appearance, the sewing hole formed by the sewing can be completely filled with the thread.

As a result, in the case of bedding, the excrement or the dead body of the house dust mite accumulated in the inside is leaked out to fundamentally prevent the allergen from being caused to the bedding user.

Further, in the case of outdoor clothing or tents, it is possible to prevent wind and moisture from penetrating through the sewing holes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a thread according to the present invention.

Referring to FIG. 1, the yarn 100 is composed of a fiber core 110 and an adhesive layer 120 applied to the outer surface of the core 110.

The fibers constituting the core 110 include all the yarns made by twisting single fibers or single fibers.

The adhesive constituting the adhesive layer 120 may be a thermoplastic adhesive, for example, an amide-based adhesive having a melting point of about 120 ° C to 140 ° C or a polyethylenic adhesive having a melting point of about 170 ° C.

In order to manufacture the yarn 100, the impregnation tank filled with a liquid thermoplastic adhesive may be formed by applying the adhesive layer 120 to the outer surface of the fiber core 110 while passing the fiber core 110, and cooling the impregnation tank.

FIG. 2 shows a principle of removing a sewing hole using the yarn of the present invention, and FIG. 3 shows a thermocompression process by a heat roller.

In order to improve the appearance of the bedding, a logo or various kinds of decoration patterns are attached or embroidery is placed by using a thread.

Referring to FIG. 2 (a), a sewing hole 12 is formed at a certain interval in the raw fabric 10 of the bedding, and the thread 100 is inserted into the sewing hole 12 by sewing.

In this state, a constant gap 12a is formed between the sewing hole 12 and the thread 100, and body and excreta of the dust mite can be discharged from the inside of the bedding to the outside through the gap 12a.

The bedding fabric thus finished is passed between a pair of opposing heat rollers to thermally adhere the bedding fabric. 3, the bedding fabric 10 having been sewn is thermally compressed by the heat rollers 20 and 22 while passing between the heat rollers 20 and 22 spaced apart at regular intervals.

The heat rollers 20 and 22 press the bedding fabric 10 while heating the bedding cloth 10 in contact with the upper and lower surfaces of the bedding fabric 10, The melting temperature should be above the melting temperature.

2B, the adhesive 120 applied to the outer surface of the fiber core 110 of the thread 100 melts and changes into a viscoelastic liquid phase to fill the gap 12a of the sewing hole 12, (12a) is missing. The molten adhesive is in a liquid state, but has a viscosity, and therefore can not flow down and can maintain a state filled with the gap 12a.

It is preferable that the release sheets 30 and 32 are attached to the top and bottom surfaces of the bedding fabric 10 before passing through the heat rollers 20 and 22 so that the melted adhesive is adhered to the heat rollers 20 and 22 .

The bedding fabric 10 having passed through the heat rollers 20 and 22 is cooled and the adhesive is changed back to a solid state due to plasticity to block the gap 12a of the sewing hole 12, The sewing hole 12 is completely filled.

Therefore, even if stitching is performed to attach a logo or decorative pattern on the bedding or to increase the esthetics of the appearance of the bedding by placing the embroidery on the bedding, the sewing hole formed by the sewing can be completely filled with the yarn 100, It is possible to fundamentally prevent allergen from being caused to the bed user.

Although the case of the bedding has been described in the above embodiments, in the case of clothes and tents for outdoor wear, it is possible to prevent wind and moisture from penetrating through the sewing holes.

In the above embodiments, bedding and tent have been described as an example. However, the present invention is not limited to this, but the present invention can be applied to all kinds of textile products requiring logos, decorative patterns or sewing for embroidery.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Accordingly, the scope of the present invention should not be construed as being limited to the embodiments described above, but should be construed in accordance with the following claims.
