BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing the structure of a conventional 3D air mesh fabric. FIG.

Referring to FIG. 1, the 3D air mesh fabric is a three-dimensional three-dimensional high-tech new material fabric formed of an upper layer, a lower layer and an intermediate layer, and polyester interlaced with warp knitting technology.

The upper and lower layers are made of polyester woven fabric so as to form a hexagonal or polygonal space. The intermediate layer is formed of a structure vertically connecting the upper and lower layers, and is formed of a polyester pile to have a cushion and a ventilation structure.

In the present invention, the 3D air mesh fabric 700 is formed of an upper layer 701, a lower layer 702, and an intermediate layer 710, and the upper and lower layers are mesh fabrics woven with polyester twist yarns to form a hexagonal or polygonal mesh space , And the middle layer is defined as a fabric of three-dimensional struc- ture consisting of pile yarn woven with polyester warp knitting technology.

Referring to FIG. 2, the thickness of the upper and lower layers of the 3D air mesh fabric according to an exemplary embodiment of the present invention is 0.3 to 0.6 mm, and the thickness of the intermediate layer 710 where the pile yarn is located is 7 to 40 mm.

Polyester, which is widely used for plastic and synthetic fiber, has a thermoplastic property. When heat is applied, it starts to deform at a certain temperature and its melting point (Melting Point) is 250 ~ 260 ℃.

The inventors of the present invention have found that, in order to more easily process a 3D air mesh fabric, in order to reduce the processing time while experiencing trial and error by various methods and to keep the cutting surface smooth and smooth more accurately than before, Method.

In order to facilitate the cutting and sewing work, the upper and lower layers 701 and 702 are formed by pressing only the intermediate layer 710 formed with pile yarn in a circular shape so as to reduce flexibility, so that the upper and lower layers 701 and 702 can be easily inserted into the presser foot of the sewing machine It is preferable to form it thin.

In addition, in the state where the elasticity of the middle layer pile yarn is retained at the time of cutting, since the cutting is not smooth and a large amount of residual material such as bop yarn is generated, the middle layer pile yarn should be processed to adhere to the upper and lower layers at the processing area.

In addition, the wide 3D air mesh fabric can be processed in a short period of time by moving the processing device from the upper side or the lower side, thereby improving the productivity.

In order to process the 3D air mesh fabric more easily, the portion to be sewn must be pressed and / or fused in advance. In order to perform the pressing and / or fusing work, a processing technique using heat of a proper temperature is required.

However, when heat is applied at a normal high temperature rather than hot air, only the upper layer 701 is deformed, and the processed portion of the product is hardened or unfavorable, resulting in deterioration of the product quality. In addition, the needle breaks at the time of sewing or the presser foot .

Therefore, when the heat treatment is performed by hot air at a high temperature which allows the upper and lower layers 701 and 702 to be deformed up to just before dissolution without modifying the upper and lower layers 701 and 702, So that the cutting and sewing process can be smoothly performed.

As a result of various experiments, the upper and lower layers 701 and 702 of the 3D air mesh fabric were woven densely with polyester yarn, and the middle layer 710 was formed with a gap between the upper and lower layers 701 and 702 The intermediate layer 710 is deformed at a lower temperature than the upper and lower layers 701 and 702 and the melting point is lower than that of the upper and lower layers 701 and 702. Therefore, And that the

As a result of various experiments, it is also possible to use a heat treatment method using various kinds of heaters and PE / PVC heat fusers other than high temperature hot winds. However, when heat treatment is applied by using these heat treatment methods, Even if heat is applied to the filament yarn or the filament yarn is deformed, the outer filament yarn is dissolved like the inner filament yarn and the subsequent process such as cutting and sewing becomes difficult, which is not suitable for the processing method of the 3D air mesh fabrics.

Accordingly, in the processing method according to an embodiment of the present invention, the upper and lower layers 701 and 702 are not deformed but are processed by adopting a heating condition using hot air at a high temperature capable of deforming only the pile of the intermediate layer 710 It is a technical feature.

As a result of an experiment according to an embodiment of the present invention, when hot air of 200 to 350 ° C is applied to the upper or lower part, the upper and lower layers 701 and 702 are not deformed, and the pile of the middle layer 710 is deformed, It was experimentally observed that the upper and lower layers were closely adhered to each other.

Also, it is experimentally shown that the hot air of 200 to 350 ° C is heated for a proper time and the pile of the intermediate layer 710 starts to melt, and the upper and lower layers 701 and 702 start to deform as well. Are inversely proportional.

Therefore, the optimum method was adopted to adjust the temperature of hot air and the time of applying hot air.

As a result of various experiments, when the hot air is blown at a speed of 30 to 100 mm / sec while blowing hot air of 200 to 350 ° C from the upper part or the lower part, the upper and lower layers 701 and 702 are not deformed, The filaments of the vertically formed filaments of the upper and lower layers 710 are deformed to be less elastic and bent so as to be bent inside the upper and lower layers 701 and 702. When the filaments are pressed and pressed by the rollers, And it was found that it was thinly processed so as to be smooth.

Referring to FIG. 3, a 3D air mesh fabric having a thickness of 7 to 40 mm is blown from upper or lower side by blowing hot air at 200 to 350 DEG C at a speed of 30 to 100 mm / sec, The upper and lower layers 701 and 702 are stably adhered to the inside of the upper and lower layers 701 and 702 while the filaments of the intermediate layer 710 are not deformed, / 8, and it is thinly processed to a thickness of 1.5 to 6 mm.

Next, in the case where the processing purpose is for cutting and sewing, the pressing part cutting step (S104) is performed after the heat treatment part pressing step (S103).

In the crimping portion cutting step (S104), a cutting process can be performed using a laser, a circular rotary knife, or the like.

The 3D air mesh fabric processing method according to an embodiment of the present invention can be variously formed through simple processes such as engraved pattern and letter design on 3D air mesh fabric which is difficult to handle.

In addition, since the portion to be cut in the 3D air mesh fabric is cut in a state in which it is thinly pressed and / or fused, the cut portion can be formed by cutting the fabric cleanly and the cut portion can be formed smoothly. There is an effect that can be.

In addition, since the portion of the sewing machine that has been subjected to the squeezing and / or fusing process is inserted and subjected to the sewing step in the frame sewing step after the cutting, the fabric can be easily fixed during the sewing work and the sewing process can be shortened.

Also, after the sewing, the sewing thickness can be made thinner than the conventional sewing machine, and the rim can be processed in a thin shape, so that the product manufactured using the 3D air mesh fabric as a whole can be made beautifully. So that it is possible to reduce defects.
