Therefore, after the antibacterial irradiation using antimicrobial mono yarn with a silver ion content of 2% to prepare a tray and a loofah.

실험예Experimental Example 2: 본 발명 항균  2: present invention antibacterial 모노사의Mono 항균 능력 조사 Antibacterial activity investigation

항균시험에 사용된 공시균주는 식중독균인 대장균 (Escherichia coli ATCC 25922) 1종과 황색포도상구균 (Staphylococcus aureus ATCC 6538) 1종, 폐렴균 (Klebsiella pneumoniae ATCC 4352) 1종 등 총 3 균주를 사용하였다.The test strains used in the antibacterial test were food poisoning bacteria. Escherichia coli ( Escherichia A total of three strains were used, including one coli ATCC 25922), one Staphylococcus aureus ATCC 6538, and one Klebsiella pneumoniae ATCC 4352.

항균 효과를 검정하기 위하여 50 mL 삼각플라스크에 10 mL NB 액체배지를 넣고 121℃에서 15분간 멸균하여 배지를 준비하였다. 여기에 공시균주인 대장균, 황색포도상구균, 폐렴균을 각각 초기농도 1.4 × 105 CFU/mL, 1.3 × 105 CFU/mL, 1.1 × 105 CFU/mL 농도로 접종하고, 시험시료를 1.0 g 첨가한 후 37 ± 1℃에서 24시간 동안 120 rpm/min의 속도로 진탕 배양한 후 배양액을 NB-Agar 배지에 도말하여 생성되는 콜로니(colony) 수로 생균수를 결정하였다. 이때 시험구는 무처리 구(blank), 일반실 첨가구, 항균실 첨가구로 구분하였으며, 항균효과를 정량적으로 나타내기 위하여 균증가율과 균감소율 (%)을 각각 하기 수학식 1과 2에 의하여 구하였다.In order to assay the antimicrobial effect, 10 mL NB liquid medium was placed in a 50 mL Erlenmeyer flask and sterilized at 121 ° C. for 15 minutes to prepare a medium. E. coli, Staphylococcus aureus and pneumococcus strains were inoculated at the initial concentrations of 1.4 × 10 5 CFU / mL, 1.3 × 10 5 CFU / mL and 1.1 × 10 5 CFU / mL, respectively, and 1.0 g of the test sample was added thereto. After vibrating incubation at a speed of 120 rpm / min for 24 hours at 37 ± 1 ℃ and then the culture medium was determined by the number of colonies (colony) produced by plating the culture medium in NB-Agar medium. At this time, the test group was divided into untreated (blank), ordinary room addition, antimicrobial room addition, and in order to quantitatively indicate the antimicrobial effect, the increase rate and the decrease rate (%) were calculated by the following Equations 1 and 2, respectively.

균증가율 (F) = Mb / MaBacterial growth rate (F) = Mb / Ma

균감소율 (%) = [(Mb - Mc) / Mb] × 100% Reduction = [(Mb-Mc) / Mb] × 100

여기서 Ma는 무처리구(blank)의 초기 균주, Mb는 24시간 배양 후의 무처리구(blank)의 균수, Mc는 24시간 배양 후의 시험 시료의 균수를 각각 나타낸다.Ma is an initial strain of a blank (blank), Mb is the number of blank bacteria after 24 hours culture, Mc represents the number of bacteria of the test sample after 24 hours culture.

이상 실험 결과를 도 2 및 표 1 내지 표 3에 나타내었다. 도 2를 보면 알 수 있듯이, 일반실 처리구는 무처리구 (blank)와 마찬가지로 많은 대장균이 증식되었다. 이에 비해 항균제를 처리한 항균실 시료는 대장균이 급감하여 NB-Agar 고체배지 상에 균이 거의 발견되지 않음을 알 수 있다. 또한 일반실과 항균실에 대하여 3종류의 공시균주를 이용하여 정량적으로 균수를 측정한 결과, 표 1 내지 표 3에서 보여주는 바와 같이 항균실은 항균력이 뛰어나게 높아 공시균주 3종 모두에서 99.9% 이상의 균감소율을 보여주었다. 이상의 결과로부터 본 발명을 통하여 제조한 항균실은 항균효과가 탁월한 기능성 모노사임을 확인할 수 있었다.The experimental results are shown in FIG. 2 and Tables 1 to 3. As can be seen from Figure 2, the common room treatment was a lot of Escherichia coli like the untreated (blank). In contrast, the antimicrobial treatment treated with antimicrobial samples showed that Escherichia coli rapidly decreased, and therefore, almost no bacteria were found on the NB-Agar solid medium. In addition, as a result of quantitatively measuring the number of bacteria using three types of test strains for the normal and antimicrobial chambers, as shown in Tables 1 to 3, the antimicrobial chambers had high antibacterial activity, which resulted in a reduction rate of 99.9% or more in all three test strains. Showed. From the above results, it was confirmed that the antimicrobial chamber prepared through the present invention is an excellent functional mono yarn with antibacterial effect.

실험예Experimental Example 3: 본 발명 항균 트레이의 항균 능력 조사 3: investigation of antibacterial ability of the present invention antibacterial tray

항균 Tray의 항균시험을 위한 공시균주로는 식중독균인 대장균 (Escherichia coli ATCC 25922)을 사용하였다.As a test strain for the antibacterial test of the antibacterial tray, Escherichia coli ( Escherichia coli ATCC 25922) was used.

항균 효과를 검정하기 위하여 50 mL 삼각플라스크에 10 mL NB 액체배지를 넣고 121℃에서 15분간 멸균하여 배지를 준비하였다. 여기에 공시균주인 대장균을 초기농도 1.8 × 105 CFU/mL 농도로 접종하고, 시험시료를 1.0 g 첨가한 후 37 ± 1℃에서 24시간 동안 120 rpm/min의 속도로 진탕 배양한 후 배양액을 NB-Agar 고체배지에 도말하여 생성되는 콜로니(colony) 수로 생균수를 결정하였다. 이때 시험구는 무처리구(blank), 일반실 첨가구, Tray 첨가구로 구분하였다.In order to assay the antimicrobial effect, 10 mL NB liquid medium was placed in a 50 mL Erlenmeyer flask and sterilized at 121 ° C. for 15 minutes to prepare a medium. E. coli, a test strain, was inoculated at an initial concentration of 1.8 × 10 5 CFU / mL, 1.0 g of test sample was added thereto, followed by shaking culture at a speed of 120 rpm / min at 37 ± 1 ° C for 24 hours. The number of viable cells was determined by the number of colonies produced by plating on NB-Agar solid medium. At this time, the test zone was divided into a blank, a blank room, a tray addition.

이상 본 발명 항균 트레이의 항균 능력 조사 결과를 도 10 및 표 4에 나타내었다. 도 10의 결과에 의하면 일반실 처리구는 무처리구 (blank)와 마찬가지로 많은 대장균이 증식됨을 알 수 있다. 이에 비해 항균제를 처리한 Tray 시료는 대장균이 급감하여 NB-Agar 고체배지 상에 균이 거의 발견되지 않음을 알 수 있다. 또한 일반실과 항균 Tray에 대하여 대장균을 이용하여 정량적으로 균수를 측정한 결과, 표 4에서 보여주는 바와 같이 항균 Tray는 항균력이 뛰어나게 높아 99.9% 이상의 균감소율을 보여주었다. 이상의 결과로부터 본 발명 항균 트레이가 항균 기능성을 가짐을 확인할 수 있었다. The antimicrobial activity investigation result of the present invention antimicrobial tray is shown in FIG. 10 and Table 4. According to the results of FIG. 10, it can be seen that the E. coli proliferates in the general treatment chamber like the untreated treatment (blank). On the other hand, it can be seen that in the tray sample treated with the antimicrobial agent, E. coli is rapidly reduced and almost no bacteria are found on the NB-Agar solid medium. In addition, as a result of quantitatively measuring the number of bacteria using E. coli in the general room and the antibacterial tray, as shown in Table 4, the antimicrobial tray showed an excellent antibacterial activity and showed a reduction rate of more than 99.9%. From the above results, it was confirmed that the present invention antibacterial tray has antibacterial functionality.

이상, 상기 실시예를 통하여 설명한 바와 같이, 본 발명은 상품성 및 경제성을 고려하여 항균력이 우수한 항균제 함량 비율을 산출하여 은이온 함유 항균 모노사와 트레이를 제공하였다. 트레이의 재질은 열성형이 가능하고, 항균능력이 우수 하며, 투명도가 탁월한 재질을 선정하여 판매촉진 효과를 고려한 것이므로, 매출증대가 기대되고 국내에서는 아직 항균 모노사 및 열성형 시트(sheet) 전용 항균 마스터배치 (M/B)를 제조하여 적용한 제품이 없으므로 원사의 사출 및 식품용 용기개발 등에 큰 파급효과를 줄 것으로 예상된다.As described above, the present invention provides a tray with a silver ion-containing antimicrobial mono yarn by calculating an antimicrobial agent content ratio having excellent antimicrobial power in consideration of merchandise and economy. The material of the tray can be thermoformed, has excellent antibacterial ability, and selects a material with excellent transparency to consider sales promotion effects. Since no master batch (M / B) has been manufactured and applied, it is expected to have a big ripple effect on yarn injection and food container development.

또한, 항균제품에 대한 요구는 일부 유통업체에 국한된 내용이 아니고 생활과 의식주에 부응한 전반적인 제품 개발에 적용이 가능한 것이므로 특히 가공제품이 아닌 신선제품의 출시가 많은 현시점에서 항균포장재 개발은 오히려 때늦은 감이 있다. 지금까지 실제 무기물질 외에도 다양한 항균제가 개발되었지만 현재까지 상용화되지 않고 있다. 그러나 본 발명 항균 마스터배치 (M/B)를 전체 플라스틱 포장재에 접목시킬 수 있을 것으로 예상되므로 상기 항균포장재의 개발을 기대할 수 있게 되었고 식품 중에서 신선제품의 유통기간은 현재 수일로 관리하고 있는데, 항균 트레이에 의해 제품의 보관수명이 연장될 수 있으므로 유통기간의 조정이 가능할 것이며, 이를 통해 업체는 매출확대 및 반품감소로 인한 수익률 향상을 기대할 수 있게 되었으므로 식품포장재 및 생활용품산업상 매우 유용한 발명인 것이다.In addition, the demand for antimicrobial products is not limited to some distributors, but can be applied to the development of overall products that meet the needs of living and food. There is this. Until now, various antibacterial agents have been developed in addition to the actual inorganic materials, but have not been commercialized to date. However, the antimicrobial masterbatch (M / B) of the present invention is expected to be able to be grafted to the entire plastic packaging material, so the antimicrobial packaging material can be expected to be developed and the shelf life of fresh products in food is currently managed for several days. The shelf life of the product can be extended, and thus the shelf life of the product can be adjusted. As a result, the company can expect an improvement in profitability due to the increase in sales and the reduction of returns, which is a very useful invention for the food packaging and household goods industry.
