Abstract

The present invention relates to a method of degumming a bast fiber and to a bast fiber degummed by the method. More specifically, the present invention relates to a method of degumming a bast fiber and a bast fiber degummed by the method, the method comprising a cleaning process of killing germs which produce a cellulose degrading enzyme, i.e. cellulase, among germs and fungi and removing foreign substances included in the bast fiber as well as impurities hidden in a bark of a bast plant by using ultrasonic waves; a first degumming process which is an enzyme degradation process to degrade α-1,4 link of pectin by using pure pectinlyase to dissolve pectin in water so that a link of pectin which joins cellulose is broken to thereby broaden a free space between fibers and thus an exposed surface area of the fiber is broaden; and a second degumming process of completely removing pectin and propecin remaining in an undegraded state during the first degumming process by using ethylene-diamine-tetraacetic acid (EDTA) and ultrasonic waves and of successively removing hemicelluloses and lignin in a physical and chemical way by using low concentration of sodium hydroxide and ultrasonic waves. Thus, in comparison with a conventional chemical treatment method of using strong alkali chemicals and a conventional degumming process of using microorganism strains, the method is not only environmentally friendly and reduces degumming time and the amount of water used, but also enables acquisition of a homogeneous and high-quality bast fiber.

Description

인피섬유의 정련방법 및 이 방법에 의해 정련된 인피섬유{DEGUMMING METHOD OF BAST FIBER AND DEGUMMED BAST FIBER USING THE SAME}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of refining bast fibers,

본 발명은 초음파를 이용한 크린공정과, 순수 펙틴리아제(Pectin Lyase) 효소를 이용한 제 1 정련공정과, EDTA(Ethylene-Diamine-Tetraacetic Acid)와 초음파를 이용한 제 2 정련공정을 포함하여 이루어지는, 인피섬유의 정련방법 및 이 방법에 의해 정련된 인피섬유에 관한 것이다.
The present invention relates to a method for producing a microfiltration membrane comprising a microfiltration process using ultrasound, a first refining process using a pure pectin lyase enzyme, and a second refining process using EDTA (Ethylene-Diamine-Tetraacetic Acid) And to a bast fiber refined by this method.

일반적으로 인피섬유(bast fiber)는, 식물의 줄기 형성층의 바깥쪽 조직에 함유되어 있는 섬유로써, 우리나라의 토양이나 기후조건에 적합한 대마, 아마, 저마, 황마 등의 마 종류가 이에 속하며, 칡넝쿨, 뽕나무, 플라타너스 등도 이에 속한다.
In general, bast fiber is a fiber contained in the outer tissue of a stemming layer of a plant. It belongs to hemp, flax, juma and jute suitable for soil and climate conditions in Korea. Mulberry, sycamore, and so on.

특히, 마 종류의 인피섬유는 친환경적인 섬유로써 이로부터 순수 셀루로즈를 정련하여 우수한 품질의 인피섬유 소재 제품이나 자동차 내장재 및 건축재인 플라스틱 복합체(Thermoplastic composite) 등의 산업용 제품에 적용되며, 더욱이 상기 인피섬유의 정련 품질은 상기와 같은 산업용 제품의 품질과 직접적으로 연관된다.
In particular, hemp type fiber is an environmentally friendly fiber from which refined pure cellulose is applied to industrial products such as a high-quality infective fibrous material, an automobile interior material and a thermoplastic composite as a building material, The refining quality of the fibers is directly related to the quality of such industrial products.

한편, 일반적인 인피섬유의 정련방법은 다량(5%이상)의 강알칼리성(NaOH 등) 약품을 사용하여 강제적으로 정련을 시키는데, 이러한 방법은 정련과정 중 환경오염이 심한 오염물질이 배출되며 또한 다량의 물이 필요하게 되어 환경적으로나 경제적으로 바람직하지 못할 뿐만 아니라, 최근 국제적으로 발효된 지구환경보호차원의 품격에도 맞지 않은 방법이다.
On the other hand, the refining method of common bast fibers is forcibly refined by using a large amount (not less than 5%) of strong alkaline (NaOH, etc.) chemicals. In this method, contaminants with high environmental pollution are discharged during the refining process, Water is not desirable because it is environmentally and economically disadvantageous, and it is a method that does not fit the dignity of global environmental protection.

특히, 상기와 같은 정련방법은 다량의 수산화나트륨(NaOH)과 같은 강알칼리성 물질을 투입함으로써 셀루로즈까지 분해시키며 이렇게 분해된 이 물질이 셀루로즈 섬유와 헤미셀로로즈 및 리그닌 간에 불필요한 가교결합(Cross-linking)을 발생시켜 변색을 유발하게 되고 이로 인해 인피섬유의 품질을 현격히 저하시키는 문제점을 가지고 있다.
Particularly, the above-mentioned refining method decomposes cellulose into cellulose by adding a strong alkaline substance such as a large amount of sodium hydroxide (NaOH), and the thus-decomposed material is unnecessarily cross-linked between cellulosic fibers, hemicellulose and lignin -linking is caused to cause discoloration and thus the quality of bast fiber is remarkably lowered.

따라서, 최근들어 상기와 같은 문제점을 해결하기 위한 정련 방법으로써 바실러스(Bacillus)균에 속하는 특정 미생물박테리아를 사용하는 생 분해 방법이 개발되었으며, 관련 선행기술로써 특허문헌 1 내지 5 등이 있으나, 아직 완벽한 실효성이 검증이 되지 못하였으며 또한 균의 배양과정에서 생길 수 있는 균의 불균일성 및 다른 잡균의 오염이 실험실에서는 차단될 수 있으나 실제 산업 현장에서는 실질적으로 완벽히 차단될 수 없는 문제점을 가지고 있을 뿐만 아니라 생 분해 숙성과정에서 발생될 수 있는 온도 및 균 자체의 활동성 차이가 항상 일정한 정련의 결과를 보장하기가 어렵다는 것도 이 방식의 큰 문제점이다.
Therefore, recently, a biodegradation method using specific microbial bacteria belonging to Bacillus was developed as a refining method to solve the above problems, and there are Patent Documents 1 to 5 as related prior arts, In addition, there is a problem that the unevenness of microorganisms and contamination of other germs that may occur in the culture process of bacteria can be blocked in the laboratory, but they can not be completely blocked in actual industrial sites, It is also a major problem of this method that the difference in temperature and activity of the microorganisms that can occur during the fermentation process is not always guaranteed to result in constant refining.

결국 마지막에는 다량의 강알칼리 및 열적처리를 하여야만 원하는 정련도의 인피섬유를 얻게 되는데, 이는 상술한 강알칼리성 약품을 사용하는 화학적 처리 방법과 동일한 문제점을 가지게 된다.
Finally, a large amount of strong alkaline and thermal treatment is required at the end to obtain the bast fiber having the desired degree of refinement, which has the same problem as the chemical treatment method using the above-described strong alkaline chemical.

EDTA(Ethylene-Diamine-Tetraacetic Acid)와 초음파를 동시에 사용하여, 상기 제 1 정련공정에서 미 분해되어 잔존하고 있는 펙틴 및 프로토펙틴(Protopectin)을 완전히 제거하며 또한 환경법에 저촉이 안 되는 낮은 농도의 수산화나트륨과 초음파를 동시에 사용하여 헤미셀루로즈 및 리그닌까지 물리, 화학적으로 제거하는 제 2 정련공정을 포함하여 이루어짐으로써, It is also possible to completely remove pectin and protopectin which are not degraded in the first refining step by using EDTA (Ethylene-Diamine-Tetraacetic Acid) and ultrasonic wave at the same time, And a second refining step of physically and chemically removing hemicellulose and lignin by simultaneously using sodium and ultrasonic waves,

종래 강알칼리성 약품만을 사용하는 화학적 처리 방법 및 미생물 균주를 사용하는 정련방법과 달리, 친환경적이면서도 정련시간 및 물 사용량을 감소시킬 뿐만 아니라 균일하면서도 고품질의 인피섬유를 획득할 수 있도록 하는, 인피섬유의 정련방법 및 이 방법에 의해 정련된 인피섬유를 제공함을 과제로 한다.

이하, 본 발명에 따른 인피섬유의 정련방법 및 이 방법에 의해 정련된 인피섬유를 상세히 설명하면 다음과 같다.
Hereinafter, the method for refining bast fibers according to the present invention and the bast fibers refined by the method will be described in detail.

본 발명은 도 1에 도시된 바와 같이, 크린공정(S100), 제 1 정련공정(S200) 및 제 2 정련공정(S300)을 포함하여 구성된다.
As shown in FIG. 1, the present invention includes a clean process (S100), a first refining process (S200), and a second refining process (S300).

상기 크린공정(S100)은, 초음파를 발진하여 인피섬유에 포함된 불순물, 이물질 및 균류를 제거 및 사멸시키는 공정으로써, 인피섬유의 펙틴을 분해하기 위한 효소 정련공정에서 셀루로즈의 손상을 초래할 수 있는 셀루라제를 보유한 모든 균류 및 곰팡이류의 사멸과 흙 먼지 등을 효과적으로 제거할 수 있는 초음파 전처리 공정이다. The cleaning step (S100) is a step of oscillating ultrasonic waves to remove impurities, foreign substances and fungi contained in the bast fibers, and to kill the bast fibers. In the step (S100), the celluloses may be damaged in an enzyme refining step for decomposing pectin It is an ultrasonic pretreatment process which can effectively remove the dirt and dust of all fungi and fungi with cellulase.

이 공정은 후술되어질 효소분해 과정인 제 1 정련 공정의 효소 발효에 의한 펙틴 분해 공정에서 사용할 효소와 펙틴 간의 직접적인 접촉면을 넓혀서 최적의 생화학적 분해를 유발시킬 수 있다.
This process can lead to optimal biochemical degradation by widening the direct contact surface between the enzyme and pectin for use in the pectin degradation process by enzyme fermentation in the first refining process, which will be described later.

구체적으로 상기 크린공정(S100)은, 인피섬유를 세척 및 5 ~ 10cm로 절단하고, 상기 절단된 인피섬유 100kg에 대하여 물 400 ~ 600리터를 투입한 후, 100±5℃의 온도에서 초음파를 주파수 20 ~ 30KHz, 강도 0.1 ~ 0.3W/cm2 조건으로 20 ~ 30분간 동안 발진시키고 세정수로 세척하여 이루어진다.
Specifically, the cleansing step (S100) comprises washing the bast fibers, cutting the bast fibers at 5 to 10 cm, injecting 400 to 600 liters of water into 100 kg of the cut bast fibers at a temperature of 100 ± 5 ° C, 20 to 30 KHz and a strength of 0.1 to 0.3 W / cm 2 for 20 to 30 minutes, followed by washing with washing water.

이때, 상기 크린공정(S100) 시, 물의 양, 초음파의 발진 조건이 상기 범위를 벗어날 경우 불순물, 균류 및 이물질이 제대로 제거되지 못할 우려가 있다.
At this time, when the amount of water and the oscillation condition of the ultrasonic wave are out of the above-mentioned range in the clean step (S100), impurities, fungi and foreign matter may not be properly removed.

상기 제 1 정련공정(S200)은, 상기 크린공정(S100)을 거친 인피섬유에 펙틴리아제(Pectin Lyase) 효소를 투입하여 인피섬유 내 펙틴을 생화학적으로 분해하는 공정으로써, 일반적으로 인피섬유의 구성품인 펙틴은 셀루로즈와 부분 결합하여 불용성인 프로토펙틴을 형성하고 있는데, 상기 제 1 정련공정(S200)은 펙틴 분해효소로 알려져 있는 순수 펙틴리아제 효소를 사용하여 고분자 펙틴의 α-1, 4 결합을 끊어 분자량이 작고 물에 쉽게 용해가 되는 올리고머로 만드는 공정이며, 상기 크린공정(S100)에서 이송된 인피섬유에 펙틴리아제 효소를 투입하고 자연 효소 발효시켜 펙틴을 수용화 시키며 섬유소의 자유공간을 확대시켜 단면적을 넓히는 과정이다.
The first refining step (S200) is a step of biochemically decomposing pectin in the infective fiber by injecting a pectin lyase enzyme into the infective fiber through the clean step (S100). Generally, the first refining step (S200) In the first refining step (S200), the pure pectin lyase enzyme known as pectin cleaving enzyme is used to invert the α-1,4 bond of the polymer pectin. The pectin lyase enzyme is added to the bast fiber transferred in the step (S100), the natural enzyme is fermented to pectinate the pectin, and the free space of the cellulose is enlarged. This is the process of widening the cross-sectional area.

구체적으로 제 1 정련공정(S200)은, 상기 크린공정(S100)을 거친 인피섬유 100kg에 대하여, 50 ~ 60℃의 세정수 400 ~ 600리터를 투입하고, 펙틴리아제 효소 0.05 ~ 0.1 kg를 넣고 55±5℃에서 20 ~ 30시간 동안 발효시킨 후, 물로 헹굼 하여 이루어진다.
Specifically, in the first refining step (S200), 400 to 600 liters of washing water at 50 to 60 DEG C is added to 100 kg of the infant fiber after the above-mentioned clean step (S100), 0.05 to 0.1 kg of pectin lyase is added, Followed by fermentation at ± 5 ° C for 20 to 30 hours, followed by rinsing with water.

상기와 같은 제 1 정련공정(S200)을 거치면, 펙틴의 α-1,4 결합이 분해되어 수용화 되며 또한 섬유소간의 간격이 벌어져 후술되어질 제 2 정련공정을 효과적으로 진행할 준비가 되며, 효소분해에 의한 상기 제 1 정련공정(S200)을 거친 세척 전 후 인피섬유(일 실시예로 인피섬유 중 대마를 적용)의 상태를 나타낸 SEM 사진은 도 2a(세척 전) 및 도 2b(세척 후)에 도시하였다.
After the first refining step (S200), the α-1,4 bond of the pectin is decomposed to be water-soluble and the distance between the fibrils is widened. Thus, the second refining process, which will be described later, SEM photographs showing the state of the bast / leaf fibers after the first refining process (S200) (in one embodiment, applying hemp in the bast fibers) are shown in FIG. 2A (before cleaning) and FIG. 2B .

한편, 상기 제 1 정련공정(S200) 시, 세정수의 양, 효소의 양 및 발효조건이 상기 범위를 벗어날 경우 효소분해과정이 제대로 이루어지지 못할 우려가 있다.
On the other hand, when the amount of washing water, the amount of enzyme, and the fermentation conditions are out of the above ranges during the first refining step (S200), the enzyme decomposition process may not be performed properly.

상기 제 2 정련공정(S300)은, 상기 제 1 정련공정(S200)을 거친 인피섬유에 EDTA(Ethylene-Diamine-Tetraacetic Acid) 투입 후 초음파를 발진하여 잔존한 펙틴 및 프로토펙틴을 완전히 제거하며 이어서 낮은 농도의 수산화나트륨을 투입하여 초음파를 발진시켜 헤미셀루로즈 및 리그닌을 제거하는 공정으로써, 일반적으로 초음파는 펙틴, 리그닌과 같은 불순물인 검(Gum)성분과 셀루로즈 사이의 작은 틈이나 구멍 사이로 에너지를 전달하여 공동화 기포(Cavitation bubble)를 형성하는데 이들이 소멸하면서 발생되는 에너지가 압력으로 전달되어 불순물인 검(Gum)을 셀루로즈 로부터 물리, 화학적으로 분리되는 성질을 이용하여 양질의 인피섬유를 획득하는 정련공정이다.
In the second refining step (S300), ethylene-diamine-tetraacetic acid (EDTA) is added to the bast fiber through the first refining step (S200), ultrasonic waves are generated to completely remove the remaining pectin and protopectin, (Sodium hydroxide) to remove hemicellulose and lignin by oscillating ultrasonic waves. In general, ultrasonic waves generate energy between a small gap or hole between a gum component such as pectin and lignin, which is an impurity such as pectin and lignin, The cavitation bubble is formed by transferring the energy generated by the extinction of the bubble to the pressure. The gum, which is an impurity, is physically and chemically separated from the cellulose, Process.

In the secondary step (S302), 400 to 600 liters of water at 50 to 60 占 폚 are introduced again after removing the water after the primary step (S301), and when 100 parts by weight of the water is added again, 1 to 1.5 parts by weight of sodium hydroxide is added to 100 parts by weight of the solution, and the ultrasonic waves are oscillated at a frequency of 30 ± 5 kHz and a strength of 0.4 to 0.5 W / cm 2 at a temperature of 100 ± 5 ° C. for 50 to 70 minutes.

상기 2차 공정(S302)은 저 농도 수산화나트륨 수용액과 초음파를 사용하여 최종적으로 헤미셀루로즈와 리그닌 그리고 아직 섬유소 안에 남아있는 검을 초음파의 섬유소내 공동화 기포의 소멸결과로 발생되는 압력 도움으로 제거하는 공정이다.
