The authors washed blankets with four new flow type washing machines and compared the rinsing effect by detecting the residual concentration of detergent in the waste water.
Acrylic blankets were used, and the washing procedures were followed the washing program of each washing machine.
HPLC was applied to analyzing the detergent concentration.
The results obtained were as follows :
(1) In the washing of blankets, the differences in rinsing effect of four flow types' washing machines are not obvious. Rinsing is more effective by dehydration after washing and during rinsing process.
(2) Rinsing effect of using washing net is more remarkable than that of each flow type washing machine.
