Description

Process to manufacture breathable fabrics

The present invention relates to a manufacturing process of a breathable fabric, and in detail to a manufacturing process for providing a breathable fabric that can be easily stretched by the action of magnetic force and wrinkles using functional yarn, magnetic yarn, and shape memory.

In order to provide clothing such as sportswear as a fabric using a sweat-absorbent quick-drying functional yarn, there is a disadvantage in that it is essential to perform single-handed processing on a woven fabric, and the fabric of the clothing is in close contact with the human body and absorbs sweat directly from the human body, so it is quick to the outside. Since it is all that is configured to discharge sweat as a function of dissipation, there is a disadvantage in that air permeability cannot be largely expected from the fabric.

In order to solve the shortcomings of sportswear manufactured by weaving sweat-absorbent quick-drying functional yarns such as aerocools, cool maxes, etc., recently, a vent is formed in the fabric to allow the air to enter and exit the human body while allowing air to cool down. Fabrics with are being developed. Prior literature related to this is Korean Patent Registration No. 10-0463229.

However, the conventional breathable fabric has a problem in that when the fabric is opened or rolled and stored, the material of the fabric is flexible and is easily distracted or wrinkles are generated by the use of the fabric. Accordingly, the present invention is to propose a process for manufacturing a breathable fabric that is easy to organize the fabric by the magnetic force of the magnetic yarn and easy to control wrinkles by the shape memory.

In detail, the second fabric 200 is a fabric provided with a magnetic field shielding material bonded to the lower surface of the first fabric 100 in order to block the magnetic field by the magnetic yarn 20 woven on the first fabric 100 . The second fabric manufacturing step (S200) comprises a second fabric preparation step (S210) provided with a magnetic field shielding material and a breathable hole processing step (S220) of processing the breathable hole 210 in the second fabric 200. Can.

In the second fabric preparation step (S210), the magnetic field by the magnetic yarn 20 of the first fabric 100 acts only on one surface of the upper surface of the breathable fabric, and is bonded to the lower surface of the first fabric 100 so that it does not act on the lower surface. It is a step of preparing the second fabric 200. In detail, the second fabric 200 is an ultra-thin magnetic field shield provided with a very thin thickness, and a magsil foil having 0.0005 to 0.030 mm may be used. Or permalloy foil, silicon steel sheet, etc. may be used, but is preferably provided as a shielding agent processed to 0.03 mm or less. The second fabric 200 prepared in the second fabric preparation step (S210) is a shielding material in which a vent hole is not formed, and the breathable hole 210 may be processed by a separate breathable hole processing step (S220).

In addition, the breathable hole 210 is preferably processed in a circular or polygonal shape, but in order to improve the magnetic field shielding effect, it is preferable that one breathable hole 210 is provided as a pair divided into two or more. In detail, as shown in FIG. 7, a cross-shaped shielding material among circular breathable holes 210 may be processed to distinguish one breathable hole 210.

Therefore, the second fabric 200 manufactured by the second fabric manufacturing step (S200) maintains a breathable effect as the breathable holes 210 are joined to correspond to the ventilation holes of the first fabric 100, however, a magnetic field It can be provided to act only in the upward direction.

Hereinafter, with reference to FIGS. 8 and 9, the third fabric manufacturing step (S300) will be described in detail. 8 is a view showing a third fabric according to an embodiment of the present invention, and FIG. 9 is an enlarged view of D of FIG. 8.

The third fabric manufacturing step (S300) may include a preparation step, a weaving step, and a reduction step similar to the first fabric manufacturing step (S100). At this time, the direct irradiation in the third fabric manufacturing step (S300) is to include the functional yarn 10, the shape memory yarn 30 and the melted yarn 40, except for the magnetic yarn 20 of the first fabric 100 desirable. Therefore, in the direct irradiation preparation step, the functional yarn 10, the shape memory yarn 30, and the molten yarn 40 are respectively prepared, and each direct irradiation is the same as the first fabric manufacturing step (S100) described above. It should be omitted. In the weaving step, the weaving of the third fabric 300 is a pair of functional yarns 10, two dissolving yarns 40, and two dissolving yarns 40, which are supplied in two or more directions in an oblique direction as shown in FIG. At the same time, the process of supplying the shape memory yarn 30 supplied between them is repeated, and the same process as the supply of the direct irradiation in the oblique direction in the weft direction can be repeated to weave the direct irradiation. At this time, the third fabric 300 is preferably a functional yarn 10 instead of the magnetic yarn 20 of the first fabric 100 is located.

It is also possible to provide clothing that can be joined by. However, if both sides of the breathable fabric have magnetic force, discomfort that may attach to unwanted metal may occur, so that the second fabric 200 is bonded to the bottom surface of the first fabric 100 to the bottom surface. The magnetic force of can be cut off. In addition, the third fabric 300 that does not include the magnetic yarn 20 may be further provided on the lower surface of the second fabric 200 to prevent damage to the second fabric 200 and to feel the breathable fabric. .

In addition, the first fabric 100 and the third fabric 300 are woven by including the shape memory 30, so that when the heat in the first temperature range is applied as described above, the wrinkles of the breathable fabric are controlled to be flattened and ironed. Without repeating, by providing hot steam, there is an effect that can wrinkle the fabric. In addition, if the hot steam in the first temperature range is provided only once after washing of the breathable fabric, the breathable fabric can be dried without wrinkles.

Therefore, the breathable fabric produced according to the present invention may be easily used when making functional objects according to various effects such as easy storage and attachment, electromagnetic wave blocking, ventilation, as well as fashion products such as clothing, shoes, and bags.

The above-described present invention relates to one embodiment, which is only an embodiment, and those skilled in the art may have various modifications and equivalent other embodiments therefrom. Therefore, the scope of the present invention is not limited by the above-described embodiments and the accompanying drawings.
