The laboratory dyeing process(Industry) is as follow:

Sample Received

Standard is checked with the Reference from the inventory

If matched then sample prepared from that recipe

If not matched than the color percentage is calculated by using Data Color

Recipe Prepared

Ways of Liquor Flow from Additional Tank mainly two:

Injection:

Means high rate flow of chemical from additional tank to main tank.

Dosing:

Rate of liquor flow change with increase of time.
