It is about.
일반적으로, 원단(原緞)은 모든 옷의 원료가 되는 천으로, 원단을 이용하여 옷은 물론 가방 등 다양한 제품을 만들게 된다.In general, the fabric (原 緞) is the raw material of all the clothes, using the fabric to make a variety of products, such as clothes as well as bags.
그리고, 가방도 직물 원단으로 만들어지는데, 가방(Bag)이란 내부에 필요한 물품을 수납하여 이동할 수 있도록 한 수납체를 말한다.In addition, the bag is also made of a fabric fabric, Bag (Bag) refers to a storage body that can be moved to accommodate the necessary items therein.
이러한 가방은 넓은 의미에서 지갑을 의미하는 펄스(Purse)/월렛(Wallet)으로부터 파우치(Pouch), 포셰 백(Pochette Bag), 배럴 백(Barrel Bag), 버켓 백(Bucket Bag), 필로우 백(Pillow Bag), 클러치 백(Clutch Bag), 쌕, 숄더 백, 토트백, 호보백, 보스턴백, 백팩, 크로스백, 등 매우 다양한 형상과 종류가 있다.These bags are Pouch, Pochette Bag, Barrel Bag, Bucket Bag, Pillow Bag from Purse / Wallet, which means wallet in a broad sense. Bags, Clutch Bags, Bags, Shoulder Bags, Tote Bags, Hobo Bags, Boston Bags, Backpacks, Cross Bags and many more.

실시예 1,2에 따른 샘플 원단 각각에 대해 내수압 테스트를 수행하였다.A hydrostatic test was performed on each of the sample fabrics according to Examples 1,2.
내수압 테스트는 디지털 내수압측정기(모델명:FX 3300Ⅳ, 제조사:Textest Instruments 스위스)를 사용하였다.The hydrostatic pressure test was performed using a digital hydrometer (Model: FX 3300IV, manufactured by Textest Instruments, Switzerland).
내수압 측정결과, 실시예 1의 샘플 원단은 1540mm의 내수압이 측정되었으며, 실시예 2의 샘플 원단은 1585mm의 내수압이 측정되었다.As a result of the water pressure measurement, the sample fabric of Example 1 was measured for water resistance of 1540 mm, and the sample fabric of Example 2 was measured for water resistance of 1585 mm.
이로써, 본 발명이 목적하는 1500mm 이상의 내수압 특성을 갖는 것으로 확인되었다.Thereby, it was confirmed that this invention has the water resistance characteristic of 1500 mm or more desired.
또한, 군용물품(예, 가방, 의류 등)에서는 공산품 품질기준에 따른 유해물질 검출 기준이 아릴아민 함량 30mg/kg 이하, 포름알데히드 함량 300mg/kg 이하, 유기주석화합물(TBT) 함량 1mg/kg 미만으로 유지되어야 한다.In addition, in military articles (eg, bags, clothing, etc.), the detection criteria of hazardous substances according to the quality standards of industrial products are arylamine content of 30 mg / kg or less, formaldehyde content of 300 mg / kg or less, and organic tin compound (TBT) content of less than 1 mg / kg. Should be maintained.
이를 확인하기 위해, 본 발명에 따른 샘플 원단의 공산품 품질기준에 따른 유해물질 검출 조건에 따라 검출한 결과, 아릴아민 함량은 샘플 원단 1,2에 대해 각각 5.1mg/kg, 5.3mg/kg으로 조건을 만족하였으며, 또한 포름알데히드 함량은 28.8mg/kg, 28.9mg/kg으로 이또한 조건을 현저히 만족하였고, 또한 유기주석화합물(TBT) 함량은 양자 모두 0.1mg/kg으로 확인되어 이또한 조건을 만족시켰으며, 이를 통해 친환경성이 있음도 확인하였다.In order to confirm this, as a result of detecting the harmful substances according to the industrial product quality standards of the sample fabric according to the present invention, the arylamine content is 5.1mg / kg, 5.3mg / kg for the sample fabric 1,2 In addition, the formaldehyde content was 28.8mg / kg, 28.9mg / kg, which also satisfactorily satisfied the condition, and the content of organotin compound (TBT) was both 0.1mg / kg, which satisfies the condition. It also confirmed that there is environmental friendliness.
뿐만 아니라, 방수성 및 발수성을 확인하기 위해 양자를 염수에 3일간 침지시킨 후 -10℃까지 냉각했다가 해동한 후 30℃까지 가열하기를 15회 반복한 후 표면 크랙여부와 변색여부를 확인하였다.In addition, in order to check the waterproofness and water repellency, both were immersed in brine for 3 days, cooled to -10 ° C and thawed, and then heated to 30 ° C for 15 times, and then surface cracking and discoloration were confirmed.
확인 결과, 양자 모두 아무런 변화가 없었고, 크랙도 발생하지 않았으며, 코팅층의 탈락도 발견되지 않았다.As a result, neither showed any change, no crack occurred, and no dropping of the coating layer was found.
아울러, 대전방지특성을 확인하기 위해 샘플 원단에 수십차례 마찰한 후 저항테스터를 이용하여 대전방지 효과가 있는지 확인하였다.In addition, after confirming the antistatic properties dozens of times to the sample fabric to determine the antistatic effect using a resistance tester.
이때, JIS T8 103의 규격에 따라 1×105Ω ≤ R(저항) ≤ 1×109Ω 범위라면 양호한 대전방지특성이 있는 것으로 판단하였다.At this time, it was judged that there was good antistatic property in the range of 1 × 10 5 kPa ≤ R (resistance) ≤ 1 × 10 9 Pa according to the standard of JIS T8 103.
측정결과, 0.26×107Ω으로 확인되어 양호한 대전방지특성이 있는 것으로 확인되었다.As a result of the measurement, it was found to be 0.26 × 10 7 Pa, and it was confirmed that there was a good antistatic property.
