  1.消耗率和計(jì)劃停臺(tái)率的選擇 根據(jù)資料選取的各工序消耗率、計(jì)劃停臺(tái)率見表3-38。
  2.各工序總產(chǎn)量的計(jì)算
  某工序總產(chǎn)量=細(xì)紗總產(chǎn)量M策工序消耗率
  已求得織物的經(jīng)、緯紗總用紗量分別為64.24kg/h和42.4kg/h,即經(jīng)紗的細(xì)紗總產(chǎn)量為64.24kg/h,緯紗的細(xì)紗總產(chǎn)量為42.40kg/h。按上述公式可計(jì)算出各工序的總產(chǎn)量。
  絡(luò)筒總產(chǎn)量:
  經(jīng)紗: 64.24×99.9%=64.18(kg/h)
