The labor cost and energy cost account for 5060% and 1015% of the total cost of dyeing and finishing process respectively . The sum of the two costs amounts to 6075%. Because an increase of the labor and petroleum cost reluctantly raise the dyeing and finishing cost, it is more needed for an advanced production systems to save both labor and energy . An attempt has been made to develope an unattended and energy-saving system in the dyeing process.
The results obtained in the plant of 8, 000 Kg/day, i.e., about 60 batches per day in productivity are :
(1) Labor saving :
i) The number of operators attending to 10 sets of dyeing machines and weighing dyestuffs was reduced from 24 to 4.
ii) Labor productivity of dyeing process including an auxiliary process was increased by about 3 times.
(2) Energy and resources saving :
i) The consumption of steam was reduced to about 1/3.
ii) The consumption of water was reduced also to about 1/3.
iii) The consumption of dyestuffs and chemicals was reduced by about 10%.
