이상견이 제사과정에 있어서 사질에 미치는 영향
Effect of abnormal Cocoons on the Silk Qualify during the Silk Reeling Process
초록
본 실험은 이상견이 제사과정에 있어서 사질에 미치는 영향을 구명하기 위해 수행된 바 그 결과를 요약하면 다음과 같다. 1. 견장, 견폭, 견중, 견층중 견층비율은 이상견이 정상견에 비하여 0.83∼4.65%가 떨어진다. 2. 견층의 두께는 20.62∼22.42%가 이상견이 정상견에 비하여 얇다. 3. 견층 sericin의 용해도는 11.75∼30.05%가 이상견이 정상견에 비하여 높다. 4. 견층연감율은 이상견이 정상견보다 6.51∼9.32% 높다. 5. 이상견은 정상견에 비하여 견사장9.43%, 견사량 8.53% 생사량비율 6.72%가 떨어진다 6. 해서율은 이상견이 정상견보다 9.58% 저하하였다. 7. 소절은 이상견이 정상견에 비하여 3점 떨어진다. 8. 대중절은 정상견에 비하여 이상견이 1.5∼3.8배나 많았으므로 대중절성적은 16.3 점이 저하되었는데 이는 특히 split ends가 많은 것에 기인된 것이다. 9. 양견수는 이상견에 있어서 정상견에 비해 1.4∼5.5배가 많고 사조고장의 주요원인이 되는 마디수는 1.9∼3.5 배나 많았다.
This experiment was conducted to know the effects of abnormal cocoons on the silk quality during the silk reeling process. The results obtained are summarized as follows: 1. The length, the width, the weight, the layer weight, and the layer ratio of abnormal cocoons are in every case 0.83∼4.65% less than those of normal cocoons. 2. The thickness of the abnormal cocoon layer is at)out 20.62∼22.4% less than that of the normal cocoon. 3. The sericin solubility of tile abnormal cocoon layer is about 11.75∼30% more than that of the normal cocoon layer. 4. The degumming ratio of the abnormal cocoon layer is about 6.51∼9.32% more than that of the normal cocoon layer. 5. The length of a have, the weight of a tave and percentage of raw silk yield of the abnormal cocoon are decreased 9.43%, 8.53% and 6.72% each as compared with those of the normal cocoon. 6. The percentage of reelability of abnormal cocoons is decreased 9.58% as compared with that of normal cocoons. 7. The neatness of abnormal cocoons is 3 per cent lower than that of normal cocoons. 8. In the cleanness test of abnormal cocoons, the number of split ends i9 about 1.5∼3.8 times as much as that of normal cocoons. Especially cleanness of abnormal cocoons is 16,3 per cent lower than that of normal cocoons. 9. The number of non-reelable cocoons of abnormal cocoons is increased 1.4∼5.5 times as much as that of normal cocoons. In abnormal cocoon, the number of knot which resulted in the breaking of silk end is increased 1.9∼3.5 times as much as that in normal cocoon.
