旦尼爾D和英制Ne的轉(zhuǎn)換
單位換算
A．特?cái)?shù)Ntex與英制支數(shù)Ne
Ne=C/ Ntex（C為常數(shù)，化纖為590.5、棉纖為583，如果為混紡紗可根據(jù)混比進(jìn)行計(jì)算，如：T/JC（65/35）45S紗線C=590.5*65%+583*35%=588，然后按公式計(jì)算便可）
B．英制支數(shù)Ne與公制支數(shù)Nm
純化纖：Ne=0.5905Nm 純棉：Ne=0.583Nm
混紡紗線：如T/JC（65/35）45S Ne=（0.5905*65%+0.583*35%）Nm
C、特?cái)?shù)Ntex與公制Nm
Ntex ×Nm=1000
D、特?cái)?shù)Ntex與旦數(shù)Nden
Nden=9*Ntex
Ne=C/ Ntex --Ntex=C/Ne
旦數(shù)Nden=9*特?cái)?shù)Ntex =9*C/支數(shù)Ne (C=590)
旦數(shù)Nden=9*590/支數(shù)Ne =5310/支數(shù)Ne
