Lab Dip
Dyeing is performed on the dyeing floor but before starting bulk production lots of work is done in the dyeing laboratory. In the lab, a lab dip or sample is developed by the textile engineer or technician. In the lab, the lab dip is matched with the sample given by the buyer. Then lab dip is sent to the buyer for his approval. In the lab, full work is done in sequence.
Process Flow Chart Of Lab Dip Development In A Dyeing Lab
In a dyeing lab, lab dip is developed like the following sequence:
Receiving standard swatch
↓
The first recipe takes from a Spectrophotometer or manually
↓
Dispersion by autodoser
↓
Trial dyeing of the first recipe
↓
Unload
↓
Normal wash
↓
Hot wash with detergent
↓
Finishing
↓
Hydro
↓
Drying
↓
Compare with a standard swatch
↓
If not ok
↓
The first correction takes from a Spectrophotometer or manually
↓
Dispersion by autodoser

The flow chart which I have given in above is all most same in the entire dyeing laboratory. But this sequence could be changed depending on the engineer’s own procedure. This procedure is applicable for yarn or fabric dyeing.
In the dyeing lab, the textile engineer should have deep knowledge about shade matching.
