The present invention relates to a functional garment and a method of manufacturing the same. More specifically, the present invention relates to the manufacture of garments including jeans products with excellent antibacterial and deodorizing properties by adding a natural antibacterial substance having antibacterial and deodorizing function in the dyeing process of yarn and using silver nanosa as a sewing thread in the garment manufacturing process. will be.

Jeans, commonly referred to as jeans, were initially worn as sailors or miners' work clothes.In modern times, jeans were made in various forms by adding synthetic fibers such as lycra, spandex, and rayon. It became clothes. However, jeans are made by denim paper cutting, which is made of a relatively thick cotton fabric, which has strong durability, but due to its thick and toughness, it is difficult to frequently wash and has a high degree of contamination compared to other garments.

In addition, the conventional jeans dyeing method has the advantage that the dyeing of the vivid color and the dyeing process is simplified by lowering the cost of the product by relying on the chemical dyeing method using the chemical dyes in most cases, but seriously due to the waste water generated after dyeing It causes water pollution, and there is a problem that dermatitis may occur by directly contacting the residue of the dyed dye of the fabric to the skin.

Recently, natural dyeing method by dyeing dyes or knitted fabrics using natural dyes, which are powdered and cochineal powders, has emerged. Does not cause any direct skin problems. However, the dyeing method using a natural dye is not easy to process the natural dye itself, and the cost of the dye is high, resulting in an uneconomical increase in the price of the dyed fabric.

In addition, in recent years, efforts have been made to manufacture friendly garment products by treating natural materials to products or fabrics to reinforce functionality such as antibacterial activity.

Japanese Patent Application Laid-Open No. 63-249701 describes a sock using copper as an antimicrobial agent. The antibacterial sock using copper has a disadvantage of causing allergy when copper is eluted from fibers by sweat or water. have.

In addition, Korean Patent Publication No. 2003-5433 treats an amino acid ester-based material on a sock as an antimicrobial agent. However, the amino acid ester-based material itself is a synthetic material, which is not environmentally friendly. At the same time, since it inhibits not only toxic microorganisms but also friendly microorganisms, the biodegradability of the fiber is low, and the damage to the ecosystem is serious.

In addition, antimicrobial products have a decay effect as the number of washing increases, making the term functional clothing colorless.

On the other hand, silver has excellent sterilization function and deodorizing function and there have been many efforts to apply it to clothing. The focus has been on enhancing the effect of silver by attaching pads to clothing areas that are usually odorous. For example, the pads are installed in the upper armpits of the upper part of the upper part of the upper part of the lower part of the lower part, but are not suitable for applying to thin clothing. The pads are not firmly fixed as time passes and the effect is increased as the number of washing is increased. There was a downside to gradually decreasing.

Therefore, the present inventors pay attention to the advantages, the functional natural material is treated in the dyeing process of the yarn to give functionality first, and then use the silver nano yarn, which has not been used conventionally as a sewing thread during garment manufacturing, the function is improved and improved for a long time An attempt was made to produce clothing that could be maintained.

Accordingly, it is an object of the present invention to provide a more improved method for producing functional garments that are excellent in antibacterial and deodorizing properties and can have long lasting effects using natural antibacterial substances.

Another object of the present invention is to provide a garment with enhanced functionality manufactured through the improved method.

The above object of the present invention was achieved by adding a natural antimicrobial material to the dyeing process of the yarn and then weaving the fabric, examining the deodorizing ability of the fabric, and evaluating whether the antimicrobial activity was maintained after using silver nanosa as a sewing thread during garment manufacturing.

The present invention is a dyeing step of the yarn is added natural antibacterial material; Fabric weaving step; Deodorizing step of the fabric; Preparing a jean using silver nano yarn as a sewing thread; And, it is composed of a functional maintenance evaluation step.

In the present invention, the manufacturing method of functional clothing excellent in antibacterial and deodorizing ability,

Dyeing the yarn by mixing ginkgo biloba powder with dye at 5 to 6% by weight, and

When manufacturing the garment is characterized in that it comprises the step of using a silver nano yarn containing 10% silver component as a sewing thread.

Jeans produced according to the functional garment manufacturing method of the present invention has an excellent effect of maintaining the initial functionality even if the number of washing 50 times or more.

In the present invention, the jeans are manufactured as a functional garment, but any form of a jean product is possible, and can be applied to other garments except jeans.

The silver nano yarn used in the present invention is used as a sewing thread by twisting 3 to 5 sum of silver nano yarn having a content of 10% of silver components. Preferably, silver nanofiber 40 males 3 go is twisted and used. This is less than 3 in the thickness of the thread is too thin, the tighter the number of washing of the jeans increases, the less robustness, 5 or more has a disadvantage that sewing is not easy because the thickness of the thread is too thick.

Hereinafter, the specific configuration and operation of the present invention will be described in more detail by examples. However, the following examples are only for illustrating the present invention, and the scope of the present invention is not limited thereto.

EXAMPLE

Example  1: functionality Jeans  Produce

In order to manufacture functional clothing having excellent antibacterial and deodorant effect, first, a natural material having excellent antimicrobial activity was added during the dyeing process of yarn, and silver nano yarn was used as a sewing thread when manufacturing jeans.

The yarn for the jeans used for this purpose was purchased from Saehan Co., Ltd. and Geumseong Spinning Co., Ltd. Weaving was conducted by the Chungnam Fabric Association, and the deodorizing ability (ammonia concentration) of the fabric was tested by the Korea Textile Technology Institute. Aldehyde deodorizing ability and antimicrobial activity maintenance test after washing of the fabric was commissioned by the Korea Apparel Testing and Research Institute.

Natural antibacterial substance uses ginkgo biloba powder. Ginkgo biloba leaves were taken in June and in mid-October, just before deciduous leaves were formed and immersed in lukewarm water maintained at 20-23 ° C for about 3 hours. After the pretreatment step, the raw materials were taken out and washed once with clean water. Then, 30 L of water per kg of ginkgo biloba was added, followed by heat treatment for 15 to 30 minutes in a hot water at 100 to 120 ° C. At this time, the boiling pot is a pressure cooker is suitable for the pressure cooker and open the gas outlet so that the odor component volatilized during boiling. The heat treatment was again performed at 110 to 120 ° C. for about 5 minutes, followed by quenching to remove internal pressure. In the course of repeating the heat treatment and cooling process, the active ingredient is extracted and concentrated, and the concentrated solution extracted from the above is filtered through a filter and then vacuum dried to prepare a powder.

Ginkgo biloba powder prepared by the above process was mixed with dye at a ratio of 5 to 6% by weight to dye yarns according to a conventional method. At this time, the dyeing time and temperature is carried out for 1 to 2 hours and the temperature at 100 to 120 ℃ depending on the type of yarn.

Next, the dyed yarn was woven into the fabric and the deodorizing ability of the fiber was examined.

Next, when manufacturing jeans, silver nano yarn was used as a sewing thread. Silver nano yarn was twisted 40 pieces of X-Static yarn spun yarn of J2L USA Scoide Co., Ltd., 10% of silver component was used as sewing thread. The washed jeans were washed to check whether they remain functional after washing.

Experimental Example  1: Ammonia and Formaldehyde of Textile Added Ginkgo Biloba Powder Deodorant  Research

Ginkgo biloba powder was added during yarn dyeing to investigate the formaldehyde deodorizing ability of the woven fiber, and ammonia concentration was examined according to KAKEN method.

Ammonia Concentration sample Ammonia Concentration (ppm) Initial concentration 2 hours later 24 hours later Blank test 40.0 34.0 21.5 Fabric of the Invention 40.0 2.6 Less than 1.0 Baseline: 1.0 ppm after 24 hours

As shown in Table 1, the ammonia concentration of the fabric of the present invention was significantly decreased from 2 hours and became below the reference value after 24 hours. Therefore, the fabric of the present invention was found to be excellent in deodorizing ability.

Next, the formaldehyde deodorization rate of the fabric of the present invention was evaluated under the following conditions through a gas detector.

Size of fabric: 10 × 10 cm (3.2 g)

Test gas: formaldehyde (2 μl is injected into the syringe)

Volume of the container: 1,000 mL

Temperature: 16 ℃, Humidity: 20%

Trial time (minutes) Deodorization rate (%) 30 56 60 58 90 60 120 63

As shown in Table 2 and Figure 2, formaldehyde deodorization rate was 56% after 30 minutes compared to the initial deodorization rate was maintained similar to 120 minutes.

Experimental Example  2: Silver nano Sewn Jeans  Investigate maintenance of functionality after washing

When fabrics made of yarn dyed with ginkgo biloba powder were made into pants, silver nano yarn was used as a sewing thread, and then the functionality was maintained even after washing.

The test conditions are as follows.

Test species: Staphylococcus aureus ATCC 6538

2) Concentration of inoculum fluid: 1.2 × 10 ⁵ cell / mL

3) Control group: raw sample

4) Nonionic Surfactant: Tween80, 0.05% of Inoculum Bacteria

5) Washing method: ISO 6330-2000, 11B, net drying after continuous washing, WOB
