In this case, as the persimmon persimmon dyeing method is improved to perform a fast color development step on the persimmon dyed fabric under high pressure and high temperature conditions, the browning reaction component contained in the persimmon juice is reduced. It reacts with the dissolved oxygen contained in the steam to induce an artificial rapid oxidation reaction (browning reaction), so that the existing oxidation and color development process, which takes at least 7 days, reaches the complete oxidation reaction point within a few hours and prevents discoloration after commercialization. Mass production is possible with uniform quality, and in particular, dye adsorption step (S10), rapid color development step ( S20), including the cooling step (S30) is the main configuration.

1. 염료흡착단계(S10)1. Dye adsorption step (S10)

본 발명에 따른 염료흡착단계(S10)는, 감 착즙액이 포함된 염료혼합액(11)에 원단(12)을 침지한 후, 탈수 및 건조과정을 거쳐 감물염색원단(10)을 형성하는 단계이다.The dye adsorption step (S10) according to the present invention is a step of immersing the fabric 12 in the dye mixture 11 containing the persimmon juice, and then dehydrating and drying the persimmon dyed fabric 10 to form the .

상기 염료흡착단계(S10)는 감 착즙액이 포함된 염료혼합액(11)이 담긴 염색조에 원단(12)을 침지하여, 원단(12)에 감 착즙액을 흡착시키되, 이때, 염색 농도는 염료혼합액(11)에 포함되는 감 착즙액 고형분비율로 조절된다.In the dye adsorption step (S10), the fabric 12 is immersed in a dyeing tank containing the dye mixture 11 containing the persimmon juice, and the persimmon juice is adsorbed to the fabric 12. At this time, the dyeing concentration is the dye mixture. It is controlled by the solid content ratio of the persimmon juice contained in (11).

그리고, 상기 염색조를 거친 원단(12)은 탈수과정을 거치는바, 여기서 탈수과정은 탈수대에 원단(12)을 올린 상태로 염료혼합액(11)을 자연 탈수하거나, 별도의 회전식 탈수장치에 투입하여 강제 탈수하도록 구비된다.In addition, the fabric 12 that has passed through the dyeing tank is subjected to a dehydration process, wherein the dehydration process involves either naturally dehydrating the dye mixture 11 with the fabric 12 placed on the dehydration stand, or putting it into a separate rotary dewatering device. to be forcibly dehydrated.

2. 속성발색단계(S20)2. Attribute color development step (S20)

본 발명에 따른 속성발색단계(S20)는, 상기 감물염색원단(10)을 습식 압력탱크(20)에 투입하고, 내부 저장된 물을 포함하는 반응액(21)이 기화되도록 히팅하여 증기를 생성하며, 증기와 함께 염료혼합액 입자가 감물염색원단(10) 섬유조직으로 침투되도록 하고, 감 착즙액에 포함된 갈변반응 성분이 증기에 포함된 용존 산소와 반응하여 인공적인 속성 산화반응(갈변반응)이 수행되는 단계이다.In the rapid color development step (S20) according to the present invention, the persimmon dyed fabric 10 is put into the wet pressure tank 20, and the reaction solution 21 containing the internally stored water is heated to vaporize to generate steam. , let the particles of the dye mixture along with the steam penetrate into the textile tissue of the persimmon dyed fabric 10, and the browning reaction component contained in the persimmon juice reacts with the dissolved oxygen contained in the steam, resulting in an artificial property oxidation reaction (browning reaction). This is the step that is performed.

이때, 상기 속성발색단계(S20)는 1.1 ~ 1.9kg/㎡ 압력 조건에서 습식 압력탱크(20) 내부 저장된 물을 포함하는 반응액(21)이 기화되는 온도까지 히팅하고, 반응액(21)이 기화되는 시점을 기준으로 50~100분 동안 반응액(21) 기화 온도를 유지하도록 구비된다. 여기서 감물염색원단(10)이 반응액(21) 증기에 노출되는 시간이 50분 미만이면 섬유조직 속까지 갈변반응 성분의 침투가 미흡하게 되고, 100분을 초과하면 섬유 손상 및 압력탱크 가열에 다른 불필요한 에너지를 낭비하게 된다.At this time, the rapid color development step (S20) is heated to a temperature at which the reaction solution 21 containing the water stored inside the wet pressure tank 20 is vaporized under a pressure of 1.1 to 1.9 kg/m2, and the reaction solution 21 is It is provided to maintain the vaporization temperature of the reaction solution 21 for 50 to 100 minutes based on the time of vaporization. Here, if the time that the persimmon dyed fabric 10 is exposed to the vapor of the reaction solution 21 is less than 50 minutes, the penetration of the browning reaction component into the fibrous tissue is insufficient, and if it exceeds 100 minutes, it is different from damage to the fibers and heating the pressure tank. It wastes unnecessary energy.

즉, 상기 감물염색원단(10)을 대기압 대비 높은 압력조건에서 가열하므로, 반응액(21)이 100℃ 이하에서 기화되고, 이로 인해 고온에 의한 원단(12)의 열손상이 방지된다. 그리고 감물염색원단(10)이 압력탱크에서 고온 고압으로 속성발색단계(S20)를 거치는 중에 감물염색원단(10)에 함유된 전분이 열에 의해 호화되면서 터치감이 유연하게 변화되는 이점이 있다.That is, since the persimmon dyed fabric 10 is heated at a pressure higher than atmospheric pressure, the reaction solution 21 is vaporized at 100° C. or less, thereby preventing thermal damage to the fabric 12 due to high temperature. And while the persimmon dyed fabric 10 is undergoing the rapid color development step (S20) at high temperature and high pressure in the pressure tank, the starch contained in the persimmon dyed fabric 10 is gelatinized by heat, and the touch feeling is flexibly changed.

이처럼 상기 속성발색단계(S20)가 고압 고온 조건에서 수행됨에 따라 감 착즙액에 포함된 갈변반응 성분이 증기에 포함된 용존 산소와 반응하여 인공적인 속성 산화반응(갈변반응)을 신속하게 유도하여 기존 최소 7일 이상이 소요되는 산화 발색공정이 수 시간 내에 완전 산화반응점에 도달함과 더불어 제품화 후에 변색이 방지되므로 균일한 품질로 대량 생산이 가능하고, 특히, 증기와 함께 염료혼합액 입자가 감물염색원단 섬유조직으로 깊숙이 침투되어 고착되므로 세탁시 물 빠짐이 방지되는 이점이 있다.As such, as the rapid color development step (S20) is performed under high-pressure and high-temperature conditions, the browning reaction component contained in the persimmon juice reacts with the dissolved oxygen contained in the steam to rapidly induce an artificial rapid oxidation reaction (browning reaction). The oxidation and color development process, which takes at least 7 days, reaches the complete oxidation reaction point within a few hours and prevents discoloration after commercialization, so mass production with uniform quality is possible. Since it penetrates deeply into the fibrous tissue and is fixed, there is an advantage of preventing water loss during washing.

또한, 상기 속성발색단계(S20)에서 습식 압력탱크(20) 내부로 과산화수소, 에틸렌가스, 이산화탄소, 산소, 탄산수소나트륨 수용액 중 어느 1종 이상을 포함하는 갈변반응제를 주입하도록 구비된다. 즉, 압력탱크(20) 내에 감물염색원단(10)을 투입하고, 뚜껑을 닫은 상태로 과산화수소, 에틸렌가스, 이산화탄소, 산소, 탄산수소나트륨 수용액 중 어느 1종 이상을 포함하는 갈변반응제를 충진하고, 이후 압력탱크(20)를 히팅하도록 구비된다.In addition, it is provided to inject a browning reagent containing at least one of hydrogen peroxide, ethylene gas, carbon dioxide, oxygen, and an aqueous sodium hydrogen carbonate solution into the wet pressure tank 20 in the rapid color development step (S20). That is, the persimmon dyed fabric 10 is put into the pressure tank 20, and the browning reagent containing any one or more of hydrogen peroxide, ethylene gas, carbon dioxide, oxygen, and sodium hydrogen carbonate aqueous solution is filled with the lid closed. , and then provided to heat the pressure tank 20 .

이에 압력탱크(20) 내부에 산소 농도가 증가되어 감물염색원단(10)의 갈변반응이 촉진되는바, 즉, 감물염색의 주요반응은 탄닌과 다른 구성성분(단백질, 미네랄, 당류, 유기산 등)이 중축합 반응하여 갈변반응을 일으키므로, 산소 농도의 증가로 인해 인공적인 속성 산화반응(갈변반응) 시간이 더욱 단축된다.Accordingly, the oxygen concentration inside the pressure tank 20 is increased to promote the browning reaction of the persimmon dyed fabric 10, that is, the main reaction of the persimmon water dyed is tannin and other components (protein, minerals, sugars, organic acids, etc.) Since this polycondensation reaction causes a browning reaction, the artificially accelerated oxidation reaction (browning reaction) time is further shortened due to an increase in oxygen concentration.

이때, 상기 탄산수소나트륨 수용액은 압력탱크(20) 내에서 65℃ 이상으로 가열하면 이산화탄소와 물 H2O를 발생하고, 탄산나트륨 무수물(無水物) Na2CO3로 변한다(2NaHCO3 → Na2CO3＋H2O＋CO2). 한편, 염산, 황산 등의 산과 작용시켜도 이산화탄소가 발생한다.At this time, when the sodium bicarbonate aqueous solution is heated to 65° C. or higher in the pressure tank 20, carbon dioxide and water H2O are generated, and sodium carbonate anhydrous Na2CO3 is changed (2NaHCO 3 → Na 2 CO 3 +H 2 O+CO 2 ). On the other hand, even when it reacts with acids such as hydrochloric acid and sulfuric acid, carbon dioxide is generated.

또한, 상기 속성발색단계(S20)에서 반응액(21)은 과산화수소, 에틸렌가스, 이산화탄소, 산소, 탄산수소나트륨 수용액 중 어느 1종 이상을 포함하는 갈변반응제가 용해된 상태로 포함되고, 반응액(21) 내에 용존갈변반응제량이 15~25ppm으로 설정된다.In addition, in the rapid color development step (S20), the reaction solution 21 contains a browning reagent containing at least one of hydrogen peroxide, ethylene gas, carbon dioxide, oxygen, and sodium hydrogen carbonate aqueous solution in a dissolved state, and the reaction solution ( 21), the amount of dissolved browning reagent is set to 15~25ppm.

상기 반응액(21) 내에 기포 발생기를 포함하는 산소용해장치를 투입하고, 소정의 시간동안 산소를 주입하여 반응액(21) 내에 용존갈변반응제량이 15~25ppm으로 설정한다. 이때 반응액(21) 온도를 상온 대비 낮은 온도에서 산소를 주입하는 것이 용존갈변반응제량 증가에 효율적이다.An oxygen dissolving device including a bubble generator is put into the reaction solution 21, and oxygen is injected for a predetermined time to set the amount of the dissolved browning reagent in the reaction solution 21 to 15 to 25 ppm. At this time, it is effective to increase the amount of the dissolved browning reagent by injecting oxygen at a temperature lower than the normal temperature of the reaction solution 21 .

이처럼 상기 반응액(21) 내에 용존갈변반응제량이 15~25ppm으로 설정됨에 따라 산소 농도의 증가로 인해 인공적인 속성 산화반응(갈변반응) 시간이 더욱 단축된다.As such, as the amount of the dissolved browning reagent in the reaction solution 21 is set to 15 to 25 ppm, the artificial property oxidation reaction (browning reaction) time is further shortened due to an increase in oxygen concentration.

3. 냉각단계(S30)3. Cooling step (S30)

본 발명에 따른 냉각단계(S30)는, 상기 속성발색단계(S20) 이후, 습식 압력탱크(20) 내부 압력을 강제 배기하면서 냉각하여 염료혼합액 입자를 감물염색원단(10) 조직 내에 고착시키는 단계이다.The cooling step (S30) according to the present invention is a step of fixing the dye mixture solution particles in the persimmon dyed fabric 10 tissue by cooling while forcibly evacuating the internal pressure of the wet pressure tank 20 after the rapid color development step (S20). .

상기 냉각단계(S30)는 습식 압력탱크(20) 내부 압력을 강제 배기시, 습식 압력탱크(20) 내부 온도가 급격히 떨어지고, 대기압에 도달하는 시점에 습식 압력탱크(20) 뚜껑을 개방한 상태로 감물염색원단(10)을 배출하게 된다.In the cooling step (S30), when the internal pressure of the wet pressure tank 20 is forcibly exhausted, the internal temperature of the wet pressure tank 20 drops sharply, and the wet pressure tank 20 lid is opened when the atmospheric pressure is reached. The persimmon dyed fabric 10 is discharged.

이후, 감물염색원단(10)에 포함된 잔류 수분을 증발시키기 위해 건조실에서 자연건조 과정을 거치면 비효소적 갈변반응을 이용한 속성 감물염색이 완료된다.After that, if a natural drying process is performed in a drying room to evaporate the residual moisture contained in the persimmon dyed fabric 10, the rapid persimmon dyeing using a non-enzymatic browning reaction is completed.

일예로서 본 발명에 따른 비효소적 갈변반응을 이용한 속성 감물염색 방법으로 감물염색원단을 제조하는 전체 과정을 구체적으로 살펴보면, As an example, if we look specifically at the entire process of manufacturing persimmon dyed fabric by the fast persimmon dyeing method using a non-enzymatic browning reaction according to the present invention,

먼저, 물 50ℓ에 탄산수소나트륨 수용액(Sodium hydrogen carbonate, NaHCO3) 8Kg(160g/ℓ= 8Kg/50ℓ) 농도의 수용액을 습식 압력탱크(20) 하부에 채우고 가열한다.First, an aqueous solution of sodium hydrogen carbonate (NaHCO3) having a concentration of 8Kg (160g/ℓ=8Kg/50ℓ) in 50ℓ of water is filled in the lower part of the wet pressure tank 20 and heated.

수용액이 65℃ 이상에서부터 CO2가 발생하기 시작하여 100℃가 되면 습식 압력탱크(20) 내부에는 CO2가 과포화상태가 된다. 또한 내부의 CO2와 함께 열, 압력, 수증기속 산소가 피염물에 접촉반응하게 되어 탄닌의 중축합(탄닌의 산화 중합)에 의한 갈변반응과 기타 성분(단백질과 미네랄, 당류, 유기산등)들의 비효소적 갈변반응이 이루어진다.When the aqueous solution starts to generate CO 2 from 65° C. or higher and reaches 100° C., the inside of the wet pressure tank 20 is CO 2 in a supersaturated state. In addition, oxygen in heat, pressure, and water vapor together with internal CO 2 reacts with the object to be dyed, resulting in browning reaction by polycondensation of tannins (oxidative polymerization of tannins) and other components (proteins, minerals, sugars, organic acids, etc.) A non-enzymatic browning reaction takes place.

그리고, 습식 압력탱크(20) 압력 1.47Kg/Cm3, 수증기 온도 93∼103℃ 에서 포화증기 상태를 지나서 과포화증기(130∼150℃) 상태에 도달하기까지 60분간 습식 증열처리 한다.In the wet pressure tank 20, the pressure of 1.47Kg/Cm3 and the water vapor temperature of 93~103℃ passes through the saturated steam state to the supersaturated steam (130~150℃) for 60 minutes.

이후 증기 토출 밸브를 열어 내부 수증기와 압력을 서서히 낮추면서 냉각단계(S30)를 수행한다.Thereafter, the cooling step (S30) is performed while gradually lowering the internal water vapor and pressure by opening the steam discharge valve.

이러한 과정 중에 고온고압상태에서 섬유장이 해리되고 느슨해진 상태(섬유의 비결정영역의 구조가 깨지면서)가 되어 염료입자들이 섬유 속으로 깊이 침투가 용이해진다. 그리고 냉각단계(S30)를 거치면서 섬유의 비결정영역의 구조가 굳어지면서 염료가 갇히게 되고 세탁내구성이 향상된다. During this process, in the high-temperature and high-pressure state, the fiber length is dissociated and becomes loose (as the structure of the amorphous region of the fiber is broken), making it easier for dye particles to penetrate deeply into the fiber. And as the structure of the amorphous region of the fiber is hardened during the cooling step (S30), the dye is trapped and washing durability is improved.

마지막으로 감물염색원단(10)을 꺼내어 남아있는 잔여 습기를 제거하면 발색이 완료된다.Finally, take out the persimmon dyed fabric 10 and remove the remaining moisture to complete color development.

도 3은 본 발명의 일실시예에 따른 비효소적 갈변반응을 이용한 속성 감물염색 방법으로 제조되는 감물염색원단을 나타내는 사진으로서, 도 3 (a)는 비효소적 갈변반응을 이용한 속성 감물염색 전 생지 섬유(원단)을 나타내는 사진이고, 도 3 (b)는 염료흡착단계(S10)를 거친 섬유을 나타내는 사진이며, 도 3 (c)는 속성발색단계(S20)를 수행한 섬유를 나타내는 사진으로서, 속성발색단계(S20)에서 속성 산화반응으로 인해 색상이 찐하게 발색됨을 알수 있다. 3 is a photograph showing a persimmon dyed fabric prepared by the fast persimmon persimmon dyeing method using a non-enzymatic browning reaction according to an embodiment of the present invention, and FIG. It is a photograph showing the fabric fiber (fabric), FIG. 3 (b) is a photograph showing the fiber that has undergone the dye adsorption step (S10), and FIG. It can be seen that the color is thickly developed due to the rapid oxidation reaction in the rapid color development step (S20).

도 4는 본 발명의 일실시예에 따른 비효소적 갈변반응을 이용한 속성 감물염색 방법으로 제조되는 감물염색원단과 기존 자연발색으로 제조되는 비효소적 갈변반응을 이용한 속성 감물염색원단을 비교하여 나타내는 사진으로서, 기존 자연발색으로 제조되는 비효소적 갈변반응을 이용한 속성 감물염색원단은 염색 직후 완전산화반응점에 도달하지 못하여 시간이 경과함에 따라 지속적으로 색상변화가 일어나는데 반해, 본원의 감물염색 방법으로 제조된 감물염색원단은 염색 직후와 시간이 경과한 후에 색상의 변화가 없음을 알 수 있다. 본원은 산화 발색공정이 수 시간 내에 완전 산화반응점에 도달함과 더불어 제품화 후에 변색이 방지되므로 균일한 품질로 대량 생산이 가능한 이점이 있다.4 is a comparison of the persimmon persimmon dyed fabric produced by the fast persimmon dyeing method using a non-enzymatic browning reaction according to an embodiment of the present invention and the fast persimmon persimmon dyed fabric using a non-enzymatic browning reaction produced by conventional natural color development. As a photograph, the fabric dyed with persimmon dye using non-enzymatic browning reaction produced with natural color does not reach the complete oxidation reaction point immediately after dyeing, and the color changes continuously over time. It can be seen that the dyed persimmon dyed fabric has no color change immediately after dyeing and after time has elapsed. The present application has the advantage that mass production with uniform quality is possible because the oxidation color development process reaches the complete oxidation reaction point within a few hours and discoloration is prevented after commercialization.

한편, 감착즙액에는 탄닌을 포함한 당류, 단백질, 미네랄, 비타민, 색소성분 등이 포함되어 있다. 특히 감탄닌의 주성분은 폴리페놀이며 높은 반응성을 가진다.On the other hand, persimmon juice contains sugars including tannins, proteins, minerals, vitamins, pigments, and the like. In particular, the main component of tannin is polyphenol and has high reactivity.

그리고, 감에 함유되는 효소에 의해 자연적으로 갈변하는 효소적 갈변반응이 존재하나 여러 가지 다른 물질들의 함유량이 높아 비효소적 갈변반응이 부가적으로 일어날 수 있다. In addition, although there is an enzymatic browning reaction that browns naturally by an enzyme contained in persimmon, a non-enzymatic browning reaction may additionally occur due to the high content of various other substances.

즉, 효소적 갈변반응은 폴리페놀의 산화반응(폴리페놀이 산화되면서 중축합하여 갈변한다. 이때 온도를 상승시킴으로써 반응이 촉진된다.)을 일컫는다.That is, the enzymatic browning reaction refers to the oxidation reaction of polyphenols (polyphenols are oxidized and polycondensed to brown. At this time, the reaction is accelerated by increasing the temperature).

또, 비효소적 갈변반응으로는 아미노카르복실반응(미야알반응, 당류와 아미노산(단백질분해)의 반응에 의해 멜라노이드 성분이 생성되면서 갈변한다.), 캐러멜반응에 의한 갈변(당류는 고온에서 산화 및 분해산물이 중합&중축합되면서 갈색물질을 형성하게 된다.), 카로티노이드 색소의 산화반응(카로티노이드 색소가 산화되면서 갈변한다.), 비타민(아스코르브산)의한 산화갈변(아스코르브산 분해에 의해 착색되면서 갈변한다.) 등이 있다.In addition, non-enzymatic browning reactions include aminocarboxyl reaction (Miyaal reaction, saccharides and amino acids (proteolysis) produce melanoid components, resulting in browning), browning by caramelization (saccharides are heated at high temperature). Oxidation and decomposition products are polymerized and polycondensed to form a brown substance), oxidation reaction of carotenoid pigment (the carotenoid pigment turns brown as it is oxidized), oxidative browning by vitamin (ascorbic acid) (coloring by decomposition of ascorbic acid) It turns brown as it becomes.) and so on.

상기 나열된 반응들을 인공적으로 촉진시키기 위하여 압력탱크(20) 내부를 고온으로 승온시키고, 산소를 포함하는 반응액을 준비한다. 또한 압력을 가하여 반응결과물(갈변물질 혹은 갈색물질)을 직물 내부로 안착시켜줌으로써 세탁내구성을 향상시킨다.In order to artificially promote the reactions listed above, the inside of the pressure tank 20 is heated to a high temperature, and a reaction solution containing oxygen is prepared. In addition, by applying pressure to settle the reaction product (brown material or brown material) inside the fabric, washing durability is improved.

이때, 폴리페놀 중합체는 매우 안정적인 구조를 이루고 있고. 이러한 구조적 특성 때문에 천연항균 및 소취기능을 포함하는 기능성을 지니게 된다.At this time, the polyphenol polymer has a very stable structure. Because of these structural characteristics, it has natural antibacterial and deodorizing functions.
