Description

Panties and its manufacturing process

The present invention relates to a panty and a method for manufacturing the same, and specifically relates to a panty made of a non-sewn by combining only the fabric and ultrasonic cutting without applying a rubber band for preventing the flow down.

In general, underwear is a basic garment directly contacting the body, and the purpose of maintaining the cleanliness, skin protection, and also to compensate for the shortcomings of the body form to serve as an ideal silhouette. The fabric used for the underwear is usually soft cotton, nylon, artificial dogs, silk, etc., which are soft to the skin, and is mainly used for elastic materials, and may be decorated with lace or embroidery. In particular, as women's outerwear material became thinner and the outerwear fits perfectly to the body, they became more interested in underwear than outerwear. Fashion concepts were introduced to create fashionable colors and designs, and various types of underwear were developed. have.

FIG. 1 is a front view of a conventional panty, in which a rubber band 25 is sewn on a part in contact with the skin of the waistband part 20 and the opening end 40 in order to prevent the fabric from flowing down and unwinding the fabric. It is shown.

The fabric of the conventional underwear is woven using a polyester-based yarn of 20 denier thickness, and the underwear was manufactured by cutting it with scissors or a knife. This is because the thickness of the thin yarn is used, so there is no force in the fabric, so the rubber band 25 and the like do not flow down.

However, in the case of wearing such conventional underwear, the padded portion causes friction on the skin or the rubber band 25 is kept tight, which is a disorder of blood circulation, and adversely affects the intestines and the genitals. In addition, the padded fabric is sewn again, so the padding part protrudes over the outer garment, which is not good in appearance, and the hand goes through a lot of manufacturing processes.

In addition, there are currently few young people who want to learn sewing technology, so it is difficult to obtain a sewing machine in reality. As a result, the sewing machine is gradually aging and the lack of sewing machine is expected to become serious in the future. have.

The present invention has been invented in view of the above circumstances, and when worn, there is no irritation to the skin and the underwear line is prevented from remaining even when the outer garment is worn on the body, and the feeling of wearing is improved, and the blood circulation and internal organs are not disturbed when worn It is an object of the present invention to provide a panty and a method for manufacturing the same, which can reduce labor in a manufacturing process.

The present invention for achieving the above object is in a panty consisting of a body portion and a waist band portion connected to the upper end of the body portion and the opening formed in both lower ends of the body portion, the end of the waist band portion and the opening is folded into an adhesive layer It is characterized in that the base fabric of the lower end portion and the inner surface fabric of the cotton type is combined with an adhesive layer made of a non-sewn.

The manufacturing method of the panty according to the present invention is a process of weaving a base fabric using a polyester-based yarn and a spanner of 40 denier thickness, a process of coating an adhesive layer on the base fabric, and then the inner surface of the cotton type on the coated base fabric Laminating the fabrics and then lapping them with ultrasonic waves and steam, and forming a lower end portion by ultrasonically cutting the laminated composite fabrics;

A step of ultrasonically cutting the woven base fabric, a process of coating an adhesive layer on the folded inner surface and the seams of the waistband portion and the opening end, and then forming the trunk by combining the folded portion and the seam with ultrasonic waves and steam;

The process of coating an adhesive layer on the adhesive portion and the lower end of the body portion, followed by attaching the body portion and the lower end by ultrasonic and steam.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;

Figure 2 is a front view of the panties according to an embodiment of the present invention, the body portion 10 and the waist band portion 20 provided on the upper body portion 10 and formed on the lower side of both sides of the body portion 10 In the panties made of an opening, the waist band 20 and the opening end 40 are folded to be shown.

The base fabric 51 used in the present invention, for example, weaving using a 40-denaer polyester-based yarn and span yarn, so it is more powerful than the fabric using a conventional 20-denier yarn, and is cut using ultrasonic waves so that the edge is fused. Unlike cutting with a knife or scissors, there is no fear of loosening of the ol, so there is no need for additional sewing.

The waistband portion 20 and the opening end 40 fold the base fabric 51 and form an adhesive layer 55 between the folded base fabric 51 to form the adhesive layer 55 as illustrated in FIG. 3 below. Let's do it. Therefore, by using the elastic and strong base fabric 51 and folding the base fabric 51, the elastic force is increased and is supported without falling down even if the rubber band is not padded.

For example, a support band made of polyurethane may be installed in the waist band portion 20 and the end portion 40 of the opening 40 (FIG. 5).

FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2 and illustrates an adhesive layer 55 formed between the base fabric 51 and the inner surface fabric 52 of the surface type.

The adhesive layer 55 uses, for example, polyamide, and is applied between the base fabric 51 and the inner fabric 52 to be combined under heat and steam. Polyamide is a coating agent based on castor oil, which is a vegetable raw material, which is harmless to the human body, and has excellent adhesion, chemical resistance, corrosion resistance, abrasion resistance, insulation, touch, appearance, hygiene, and low cost.

For example, a lyocell is used as the inner surface fabric 52. Lyocell is a scientific name of new material fiber. It is a cellulose fiber that combines the excellent functional properties of chemical fiber with the natural feel and hygroscopicity of natural fiber.It is a kind of cotton and has excellent hygroscopicity and breathability. It maintains morphological stability and water washing because it maintains strength of about 85% even when wet and similar to ester fiber.

Figure 4 is a rear view of the panties according to an embodiment of the present invention, the body portion 10 and the waist band portion 20 provided on the upper body portion 10 and the lower side of both sides of the body portion 10 In the panties made of the formed opening, the waist band portion 20 and the opening end portion 40 are folded and folded, and the body portion 10 is formed as a seam 45 at the rear center portion.

As described in FIG. 2, for example, the base fabric 51 is woven with a polyester yarn and a spanner having a thickness of 40 denier, and ultrasonically cut so as not to loosen, and then the waist band portion 20 and the end of the opening 40 are folded. After coating the adhesive layer 55 on the inner surface and laminating it with heat and steam, coating the adhesive layer on the seam, and abutting the end portion of the torso part 10 with the ultrasonic wave and steam to form the torso part.

Figure 6 is a block diagram illustrating a manufacturing process of the panties according to an embodiment of the present invention, weaving the base fabric 51 using a 40-denier polyester yarn and span yarn to the base fabric 51 Coating the adhesive layer 55, laminating the inner surface fabric 52 of the surface type, laminating it with ultrasonic waves and steam, and then ultrasonically cutting the lower portion 35; Ultrasonic cutting of the base fabric 51 woven in the same manner and coating the adhesive layer 55 on the folded inner surface and the seam 45 of the waist band portion 20 and the opening end 40, and then the ultrasonic wave and steam to be combined with the body By molding 10; The manufacturing process of the panty made of a seamless material is formed by coating the adhesive layer 55 on the body portion 10 and the adhesive portion 55 by laminating the adhesive portion of the lower portion 35 and attaching and attaching them by ultrasonic and steam. .

As described in FIG. 2, for example, the base fabric 51 is woven using a polyester-based yarn and a span yarn of 40 denier thickness, and thus, is stronger than a fabric woven with a conventional 20 denier yarn, for example, polyamide. Since the elasticity of the waist band portion 20 and the opening end 40 is improved by using the adhesive layer 55 made of ultrasonic wave and steam, it is not necessary to add a separate rubber band 25 and sutures by using ultrasonic cutting. In order to eliminate the need for a separate sewing process, the number of stitches is reduced, the process is simplified, and the manufacturing cost is reduced.

In the preferred embodiment of the present invention has been described with respect to the panties manufactured using a single layer of the base fabric 51, the base fabric 51 and the base fabric 51 may be manufactured by including the adhesive layer as described above.

In addition, various patterns can be inserted into the base fabric 51. In particular, when two layers of the base fabric 51 are combined, the patterns can be embossed or engraved using ultrasonic waves. Insertion of the pattern using the ultrasonic wave gives aesthetics and at the same time reinforces the strength of the fabric.

In the preferred embodiment of the present invention, panties are shown, but it is apparent to those skilled in the art that the present invention can be applied to other kinds of underwear within the technical spirit of the present invention.

As described above, according to the present invention, since the rubber band is not attached to prevent the sewing work and the falling down, there is no irritation to the skin when worn and the underwear line is prevented from remaining even when the outer garment is worn on the body. It is effective in reducing blood circulation and internal organs, and reducing manufacturing costs in the manufacturing process.
