Indigo Calculations



For 12 ropes, at 24 m/min, of 344 ends of 14000 m length of 7s count.

wt of yarn = (12*344*14000*100*453.6)/(7*840*36*2.54*1000) kg= 5000 kg

at 24 m/min, a lot of 14000 m will be completed in 14000/24 = 583.3 min

at 1.8% shade
100 kg of yarn needs--> 1.8 kg of Indigo
5000 kg of yarn needs --> 90 kg of dye

at 100 gpl
100 gms of dye = 1 lit of solution
90 kg of dye = 900 litres

900 litres should be completed in 583.3 min
1 litre would be completed in = 583.3/900= 38.8 seconds

so flow rate will be 38.8 seconds / litre

Similarly flow rate of caustic and hydro can be determined

Hydro is taken around 100 gpl
caustic is taken around 90 to 100 gpl
