旦数

实验结果表明，预牵伸倍数应根据氨纶丝规格不同而改变，旦数越大，氨纶丝预牵伸倍数越大；

The results showed that the pre-draft times should be changed with the specifications of the spandex .

采用这种度量方法时，旦尼尔数越低，则纱线越细。

In this system the lower the number , the finer the yarn .

因此一个化纤长丝是以它的旦尼尔数和它纱线中的纤维数为特征的。

Thus a filament yarn is characterized by its denier and the number of fibers in the yarn .

厚裤袜，在寒冬里救了我的命。我用我袜子的旦尼尔数作为方程的基数，因为那就够帮任何人度过寒冷且大风的天气了。当天气暖和明媚，建议的旦尼尔数就会减少。”

I made those tights my basis for the formula because they should see anybody through cold and windy weather , and then when it 's lovely and sunny , the denier recommendation reduces . '
