This experimental work is aimed to find out if there is a reasonable tussah silk reeling service. The results obtained are as follows, 1) The best silk reeling rate of tussah cocoon was 8.02% by dupion reeling machine, 7.44% by common with Autumn cocoons, and 7.23% by dupion machine, 6.79% by common with Spring. Those results are sup-erior to 6.00% of the former. 2) The cocoon grading ratio was 63∼68% with Autumn cocoons md 66∼70% with Spring. Spring cocoons showved more 2∼3% than Autumn in cocoon grading ratio. These seem to be resulted from the weather condition. 3) The reeling efficiency was 70g per labor for an hour. 4) The strength of tussah silk war 3g/d and elongation 26% The strength of tussah silk is weaker, and the elongation of it larger than those of raw silk. 5) As these results, the enterprise of the tussah silk reeling has become possible, and will develop as a new industry. Therefore. it is demanded that this new industry will be helped by the Government to get foreign money.
