전 세계적으로 ``지구환경 보호운동``과 웰빙 삶이 확산되면서 환경과 인체에 부정적인 영향을 미치고 있고, 특히 합성섬유의 주원료인 원유가 멀지 않은 장래에 고갈될 것을 예상하고 있으며, 이에 대한 대안으로 새로운 천연섬유 소재의 창출에 대한 연구가 활발하게 진행되고 있다. 따라서 본 연구는 천연섬유의 주산지가 될 수 있는 자연 환경적 요소를 갖추고 있는 캄보디아 천연섬유 작물 현황을 조사하여 추후 한국 농산업체의 천연섬유 생산에 대한 투자를 대비한 정보를 제공하고자 조사 연구하였던 바 결과를 요약하면 다음과 같다. 1. 현재 캄보디아의 천연섬유산업은 소규모로 아직 초기 단계에 있으며, 조사된 황마, 부레옥잠 등 열대식물도 있지만, 왕골, 갈대, 목화 등 온대지역에 자생하는 천연섬유 등 12가지 작물이 대표적인 천연섬유 작물로 조사되었다. 2. 누에를 이용한 실크산업은 캄보디아의 저렴한 노동임금으로 부가가치 창출이 쉬운 산업으로 캄보디아 정부에서 활성화 길을 모색하고 있으나, 기술력 향상을 위한 인력양성이 가장 큰 문제점으로 대두되고 있다. 3. 목화를 이용한 천연섬유 생산은 대단위 노동집약적 산업으로 수출활로의 전망은 좋으나 주로 북부지역이 주 생산지로 인구밀도가 적은 농촌지역에서 활성화시키는데 한계점이 있는 것으로 나타났다. 4. 캄보디아의 열대성기후와 정부의 지원, 세계의 천연섬유 산업의 트렌드와 더불어 천연섬유 분야의 전문가 양성과 해외 투자자유치, 섬유생산기술 발전 등을 동반한다면 캄보디아는 새로운 천연섬유생산기지로 발전 가능성이 있는 것으로 조사되었다. As the health conscious culture, or the so-called ``well-being culture`` arose in our society, consumers started to have higher standards upon choosing which goods to purchase. Nowadays, products which are not harmful to the body as well as which are environmental friendly are being preferred. In relation to this movement, the demand of natural fibers in the global market has been continuously increasing compared to synthetic fibers which are made by harmful chemicals. In this study, we have conducted a survey on the production and the uses of the finished products of natural fibers after being processed. The objective of this study was to provide an up-to-date information on Cambodia`s natural fiber industry to Korean investors, open to the possibility of the future development of natural fiber market in Cambodia. The industry of natural fibers in Cambodia relies mainly on domestic materials wherein the products are handcrafted and the craftsmen earn a small amount of income since large scale production has not yet been established. According to our survey, crops in Cambodia which can be used to make natural fiber are Kapok, Jute, Screw pine etc. including silk, Cotton and Cyperus grown in temperate areas. Despite of the abundance in resources, these are not optimally utilized for the production of natural fibers due to the lack of the natural fiber processing technologies. The future of natural fiber industry in Cambodia is very promising. Creating a favorable environment conducive for growing natural fiber crops will be crucial for the production of natural fibers. In addition, intensive and integrated training to come up with qualified technicians for natural fiber processing would be as key factor that would greatly contribute to the acceleration of Cambodia`s natural fiber industry`s development.

In recent, the cultivation of maize in the world is being increased as a feed for the animal due to the increase of the large amount of meat consumption. However, reduction of supply for the feeding maize by the natural disaster such as drought, flooding, and demanding materials for bioenergy are attributed to increase the cereal price of the world that caused for the fluctuation of prices. The research has been done to provide useful information to the Korean agricultural investor regarding the current status of maize production and distribution in Cambodia. The maize cultivation of Cambodia in 2009 presented as a second major crop at the area of 6.8% in the total crop production area, and it continuously increased maize production yearly basis for the internal uses as well as for the exportation. The total amount of production showed by amount of 0.92 million tons due to the increased production of unit area. The yield production of unit area in current shows about 4 tones per hectare. About 90% of total production produced during August to September at wet season, and area of Batambang province produced about 70% of the total production. The production of feeding maize cultivated about 70% of the total cultivation area, and the exportation have done around 60% and remains were consumed as a domestic uses. The prospects of maize production in Cambodia will be increased due to the acceleration of livestock industry as 8.7% of annual growth rate.

International price of cereal has been dramatically increasing for the past few years. This price hike amplified the importance of food self-sufficiency in numerous countries due to the fact that food security is directly proportional to food self-sufficiency. In this study, we conducted a survey to provide useful information of Cambodia`s agricultural environment to possible Korean agricultural investors and as to highlight Cambodia as a strong candidate for the establishment of Korea`s foreign base for cereal production. The survey conducted includes information regarding Cambodia`s agricultural environment and investment circumstances including the political, economical and other contributing factors affecting agricultural investment in Cambodia. Seventy percent of the Cambodia`s total population engage in agriculture and this comprises about 30% of the country`s GDP. This statistics reflects the possibility of Cambodia`s poverty alleviation which proves that agriculture in Cambodia is the driving force for the improvement of the country`s economy. In addition, low labor cost, fertile land, abundant water resources, like the Tonle sap lake and the Mekong river, and unreclaimed lands are the strong points that could attract agricultural investors to Cambodia. Poor infrastructure, irrigation systems, law reforms, including social and cultural differences may be the biggest setbacks for the acceleration of Cambodia`s agriculture development. However, the Cambodian government is open and willing to make adjustments for Cambodia to be both foreign and domestic agricultural investor-friendly, expecting that it will boost its country`s agricultural development. Making the best out of this opportunity, the coordination of KOICA with Korean agricultural investors in building infrastructures and with the help of the KOPIA program for the transfer of agricultural technology will benefit both countries and will play an important role in Cambodia`s agriculture.

As a raw material for pulp and paper industry, Moso bamboo, Timber bamboo and Henon bamboo pulps were prepared by soda or soda-anthraquinone(Soda-AQ) pulping process. Soda–AQ pulp yields was higher in Henon bamboo (43.2%) than in Moso bamboo or Timber bamboo (32.7-39.2%), but quite lower than hardwood species. In Kappa number comparison, Henon bamboo pulp showed lower (16.6) with 50 min cooking to 170 ℃ than that of Moso bamboo (22.8) and Timber bamboo (18.9) with 90 min cooking to 170 ℃. Fiber length of Timber bamboo soda pulp had higher (1.46 mm) than that of Moso bamboo or Henon bamboo (1.18-1.36 mm). All three bamboo pulps showed longer average fiber length than commercial hardwood pulp. With higher pulp yield and lower Kappa number, Henon bamboo is better raw material for pulp than Moso bamboo and Timber bamboo.

Moso Bamboo was investigated as the a raw material for pulp and paper industry. Soda-Anthraquinone (Soda-AQ) pulping, elemental chlorine free bleaching was applied. Yield of soda or soda-AQ pulp was 29.3-31.7% with Kappa number 33.0-22.8 with different cooking time or anthraquinone addition at 20% active alkali. In soda or soda-AQ pulping, 81-86% of xylan was removed, which was the main reason for lower pulp yield than hardwood species. Average fiber length of Moso Bamboo soda-AQ pulp was 1.36 mm with 15.5 μm fiber width. Soda-AQ pulp from Moso Bamboo (P-3, lowest Kappa pulp) was bleached with 5.5-6.5% of chlorine dioxide charge as D0ED1 bleaching sequence. In 3-stages ECF bleaching, final brightness of 85.3% ISO was achieved with total chlorine dioxide 6.5%.
