Description

[0001] SEWING STRUCTURE AND SEWING APPARATUS [0002]

The present invention relates to a sewing structure without a bottom thread, and more particularly, to a sewing apparatus having a bottom thread, and more particularly, to a sewing apparatus having a bottom thread, The present invention relates to a sewing structure without a bottom thread that can improve the productivity of sewing work and improve the quality of sewing, and can reduce the sewing cost, and a sewing apparatus therefor.

In general, sewing work using a sewing machine is performed by alternately sewing an upper thread (also called a sewing thread) and a lower thread (also called a drum thread) of a drum (also called a drum) on the cloth.

However, since the drum is small in size, there is a limit in the length of the lower thread that can be wound, so that the lower thread is dropped due to continuous use of the sewing machine, and manual operation is required to replenish the thread in a short time. In addition, the drum requires a preliminary work to prepare by winding the lower thread before use. Such a preliminary work requires separate dedicated equipment, and it takes a lot of time and labor costs.

As a method for solving the above-mentioned conventional drawbacks, a "lower thread supply device for a sewing machine" as disclosed in Korean Patent Publication No. 1995-0011286 (Publication Date: 1995. 09.30; Application No.: 10-1993-0030043) , And a "lower thread supply device for a sewing machine" as disclosed in Korean Patent Laid-Open Publication No. 10-1988-0001868 has been proposed.

According to the lower thread supply device of the conventional sewing machine as described above, the lower thread can be theoretically supplied continuously without interruption at the time of sewing work, but it is structurally complicated and practically impossible due to the complicated driving mechanism of the sewing machine, There is also no sewing machine that is commercialized.

Even if the lower thread is continuously supplied by the lower thread supply device of the conventional sewing machine, since the lower thread is cut off due to excessive tensile force, friction or interference in the sewing process, it needs to be connected, Resulting in deterioration of the performance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings 1 to 10, and the same reference numerals are given to the same constituent elements in FIG. 1 to FIG. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

FIG. 1 is a view for explaining a sewing structure without a bottom thread according to a first embodiment of the present invention. FIG. 1 is a cross-sectional view of a part of a sewing structure.

1, a sewing structure without a bottom thread according to a first embodiment of the present invention includes a sewing product n having a planar structure and a plurality of stitches arranged to form various types of sweat on the sewing product n And the upper thread (t) is not provided, and the lower thread is not provided for fixing the upper thread (t) in the sewing process.

Particularly, the sewing structure according to the present invention is characterized in that the upper thread t is composed of a loop portion t1 forming sweat, a fastening portion fused to the tissue of the sewed product n and formed below the loop t1 t2).

The fixing portion t2 is a portion which is fixed to the tissue of the sewed product n to perform the function of supporting the loop t1 which forms the sweat. In order to form the loop t2, Or more, and is melted when heated.

For example, the upper thread (t) can be selectively applied to any fiber yarn having a property of being melted during the ultrasonic heating. Most of the synthetic yarns such as polyester and nylon are subjected to the ultrasonic welding process So that it is possible to form the fixing part t2.

In addition to the synthetic fiber yarn, the upper yarn (t) may be a monofilament yarn formed of a resin melted and fixed at the time of application of heat.

Here, the resin may be selected from a mixture of a thermosetting polymer, a thermoplastic polymer, a thermosetting polymer and a thermoplastic polymer. At this time, the thermosetting polymer may be selected from polyether, polyester, polyimide, polysulfone, epoxy resin, unsaturated polyester resin, phenol resin, urethane resin, urea resin and melamine resin. The thermoplastic polymer may be selected from polyamide, polyester, liquid crystal polymer, polyethylene, polypropylene, phenylene sulfide, and polystyrene.

Preferably, the thermosetting polymer and the thermoplastic polymer are selected so as to have a low melting point. In this embodiment, a thermoplastic polymer composed of a low melting point resin so as to be melted at a temperature in the range of 100 ° C to 200 ° C Is applied.

On the other hand, the sewed product (n) can be selected and applied to any material having a planar structure capable of sewing work. For example, a foamed foam pad, a synthetic resin sheet, a nonwoven fabric, leather, Typically, fabric is applied.

The sewing structure without the bottom thread according to the first embodiment of the present invention as described above can form sweat so that it can provide not only the binding function of the sewing material but also the unique feel of sweat, It is possible to perform continuous sewing without replacing the lower thread during the sewing work, and it is possible to improve the productivity of the sewing work because the pre-work for winding the lower thread around the drum and the replacement work are not required, There is an advantage that the cost can be reduced.

In addition, there is an effect that it is possible to fundamentally prevent problems such as cutting of the lower thread due to excessive tensile force, friction or interference in the sewing process as in the prior art, or stopping the work while being twisted.

FIGS. 2A to 2C are partially enlarged perspective views illustrating an upper thread applied to a sewing structure without a bottom thread according to a first embodiment of the present invention. FIG.

Referring to FIG. 2A, the upper thread t is composed of a supporting line t3 for forming sweat, and a fused portion t4 provided in association with the supporting line t3 and made of a material meltable by heat.

The support line t3 is composed of a non-fusion welder t31 formed of a material which is not heat-fused, such as natural fibers such as a face, a wool, a dog, Is composed of a lamination portion t41 laminated on the non-fractured ship t31 and formed of a heat-melting material.

The laminated portion (t41) is typically formed by laminating a thermoplastic polymer composed of a low melting point resin on the surface of a supporting line by coating or coating.

As shown in FIG. 2A, if the upper thread t is not formed of a material capable of being melted as a whole but the support line t3 formed of a cost ridge is disposed at the center, Even if the heat is generated, only the melted portion (t4) melts and the supporting line (t4) is not melted and remains while performing the supporting function, so that the upper thread supply failure and sweat formation defect And exhibits a unique synergistic effect that can be prevented in advance.

2B, the upper thread t is constituted by a supporting line t3 for forming sweat and a molten portion t4 formed by a material which is supplied with the supporting line t3 and is meltable by heat, and the supporting line t3 The molten portion t4 is composed of a plurality of strands of non-melting molten yarn t31 which are not heat-melted. The molten portion t4 is composed of molten yarn formed by a hot molten material such as monofilament yarn, t42). At this time, the molten ship preform t42 is formed to have a larger denier (outer diameter) than the non-weld welder t31 so that the welded portion t2 can be easily formed.

The upper thread t shown in FIG. 2B is also formed by a supporting line t3 formed by the non-welded thread t31 like the upper thread shown in FIG. 2A, and has a unique synergy effect Since the melted portion t4 is composed of the molten prepara- tion t42, it is advantageous in that it can be simply manufactured in such a manner that the molten portion t4 is superimposed on the non-reinforcing yarn t31 through the process of manufacturing the fiber yarn. Thus, as shown in FIG. 2A, the thermoplastic polymer is advantageous in that it has excellent manufacturability and can reduce manufacturing cost as compared with a manufacturing method of forming the laminated portion t41 by applying the thermoplastic polymer on the surface of the supporting line t3.

Meanwhile, the upper thread t may be formed in various forms other than those shown in FIGS. 2A and 2B, provided that the upper thread t has the supporting line t3 and the fused portion t4.

For example, as shown in FIG. 2C, the supporting line t3 and the melting portion t4 are both formed of a molten yarn made of a material to be thermally melted, and the molten prepacker t32 composed of the supporting line t3 has a temperature The molten prepara- tion t43 composed of the molten portion t4 is composed of the thermoplastic polymer composed of the high melting point resin so as to be melted in the molten prepara- tion t32 composed of the support line t3 And is formed of a material such as a thermoplastic polymer composed of a low melting point resin having a melting point in the range of 100 占 폚 to 180 占 폚 and having a lower melting point.

And FIG. 2D is a partially enlarged perspective view for explaining another upper thread applied to a sewing structure without a bottom thread according to the first embodiment of the present invention.

Referring to FIG. 2D, the upper thread t is composed of a functional wire p1 forming sweat and a fused portion t4 formed by a material which is supplied with the functional wire p1 and is meltable by heat.

Here, the molten portion t4 is constituted by the molten glass preform t42 formed of a hot molten material as described above. Here, the melted portion t4 may be composed of a lamination portion (not shown) formed of a heat-melting material.

Here, the conductive wire includes a conductive yarn having conductivity so as to have flexibility and soft touch similar to that of the fiber yarn, and a fiber yarn to be disposed along with the conductive yarn. For example, as shown in Fig. 2 (d), the conductive wire has a structure in which a core yarn p11 formed by a fiber yarn at the inner center and a plurality of stranded electric conductor p12 wound around the core yarn p11 are used.

The conductive p12 may be supplied by selecting at least one or more of a preform formed of a conductive material and a preform containing a conductive material.

Here, the fiber yarns forming the center yarns are selectively applied from among inorganic fibers or organic fiber yarns depending on the use of the functional wire material p1 and the sewed product (n), and the preforms formed of the conductive material are made of a conductive metal such as copper or stainless steel Conductive metal or carbon yarns formed may be applied.

When a conductive metal yarn is selected, it is preferable to have a diameter in the range of 10 to 500 micrometers (占 퐉). This is because at least one conductive metal yarn is contained in at least one strand so that the total diameter of the conductive wires in the state of being composed of conductive wires should be 1000 micrometers or less so that the foreign object can be minimized in a state of being arranged in the sewing product.

In addition, a pre-shrinkable film including a conductive material may be a preform having a conductive body coated with a conductive polymer on the outer surface of a linear body composed of a bundle of filament yarns, a preform having conductive materials such as metal oxide nanoparticles and graphene, (Conductive metal nano-particles, metal oxide particles, graphene, etc.) may be contained in the conductive layer.

Here, the functional wire p1 described above is typically applied to the supplementary wire p.

The fixed part t2 is constituted by a pull-in type fixing part which is melted and formed in the state of being drawn into the inside of the sewed product n by a needle. Such a lead-in type fastening part is integrally fixed together with the fibrous tissue of the sewing product in the inside of the sewed product (n), and therefore has a high fixing strength, so that the outer diameter of the supplementary wire (p) is large, And the like.

The auxiliary wire p is bound and fixed to the ring t1 formed by the upper thread t supplied from the auxiliary wire feeder 120 as described in the following sewing machine.
