  • This study was carried out to investigate the utilization value of legume crops collected in tropical and subtropical areas. We examined agronomic traits to assess domestic adaptability and evaluated useful components of foreign legumes. We used a total of 201 genetic resources of three legumes, consisting of 68 lentils, 72 chickpeas and 61 guars. The average number of days to flowering of the three legumes ranged from 56.7 to 60.8 days; the shortest in guar and longest in chickpea. The average number of days to growth of the three legumes ranged from the shortest 86.8 days in lentil, to the longest 163.9 days in guar. The maturation period of the three legumes lasted from the end of May until mid-September, based on sowing in March. However, the average yield of lentil was very low, ranging from 0.5 g to 30.6 g, with an average 16.4 g based on 10 plants per accession. The average 100 seed weight of the three legumes was 2.2 g for lentil, 22.9 g for chickpea, and 3.8 g for guar. The crude protein content ranged from 14.1% to 32.4% with an average of 20.4%, the highest for guar and the lowest for chickpea. The average crude oil content in the three legume crops was generally low, ranging from 0.8% in lentil, to 4.3% in chickpea. The average dietary fiber content in the three legume crops varied from 15.7% to 50.7%. Guar was the highest source of fiber, followed by chickpea (19.3%) and lentil (15.7%). From the agricultural traits analysis, chickpea and guar could grow domestically. However, lentil was difficult to flower and fruit normally during the warmer season after May. Therefore, lentil should be considered for late summer cropping during the cool season. The physicochemical properties of the three legumes seem to be useful as they are similar to, or better than, those of the control common bean.

  • 복합방사에 의해 복수의 성분을 단섬유내에 함유하고 있는 섬유를 복합섬유라 하며 복합섬유에는 천연섬유인 양모섬유가 있고, 합성섬유로는 sheath/core형, side-by-side형, 해도형 등의 다양한 형태의 섬유가 있다. 최초로 side-by-side형의 비스코스 섬유가 1937년에 발명 되었고, 이후 1960년대부터는 나일론 복합섬유가 양말ㆍ메리야스류, 부직포 제조의 용도로 사용되기 시작했고 최근에 와서는 극세섬유나 권축섬유 등 특수한 기능을 가진 섬유를 제조하기 위한 수단으로 sheath/core형을 비롯한 많은 형태의 복합섬유가 다양한 고분자의 조합으로 제조되고 있다[1].(중략)
