8、/22-25cm Wools & fabric high water level throughout the wash formula 羊毛織物整個(gè)洗滌程序要保持高水位,Water levels水位 Overloading/underloading of wheels 超載/低載 Over sudsing泡沫過多 Wash wheel design (pullman and Y-pocket higher water level than open pocket washers) 洗衣機(jī)的設(shè)計(jì)（臥式或Y艙的水位比開艙式的要高）,Washing Formula 洗滌程序,Absorbed Wa

9、ter & Free Water織物吸收水&未吸收水,Absorbed water cannot be removed from the washer by merely draining 織物吸收水不能通過排水從織物中排走的水,Washing Formula 洗滌程序,Free water water added after saturation to achieved desired water level 織物未吸收水織物吸收飽和后，再加入的達(dá)到設(shè)置水位的水。 Washing & Rinsing continuous interchange between free & absorbed

10、 until a state of equilibrium between soil or chemicals in the fabric and water in the washer 主洗&過水吸收水和洗衣機(jī)內(nèi)的未吸收水之間不停交換直到洗衣機(jī)內(nèi)污垢或清潔劑達(dá)到某種平衡,Washing Formula 洗滌程序,Absorbed Water & Free Water織物吸收水&未吸收水,Initial Flush 頭道沖洗,Remove soil 去污 Raise the temperature of the linen 提升織物溫度 Lower the alkalinity before
