Process Flow Chart Of Lab Dip Development In A Dyeing Lab | Shade Matching Procedure

Posted by Textile Fashion Guide: A Dedicated Textile Fashion Education Informations Blog

Dyeing is performed in the dyeing floor but before starting bulk production a lots of work is done in the dyeing laboratory. In the lab, lab dip or sample is developed by the textile engineer or technician. In lab, lab dip is matched with the sample given by the buyer. Then lab dip is send to the buyer for his approval. In lab, full work is done in sequence.



In a dyeing lab, lab dip is developed like the following sequence:

Receiving standard swatch



First recipe take from Spectrophotometer or manually



Dispersion by autodoser



Trial dyeing of first recipe



Unload



Normal wash



Hot wash with detergent



Finishing



Hydro



Drying



Compare with standard swatch



If not ok



First correction takes from Spectrophotometer or manually



Dispersion by autodoser



Trial dyeing of first recipe



Unload



Normal wash



Hot wash with detergent



Finishing



Hydro



Drying



Compare with standard swatch



If not ok



Second correction takes from Spectrophotometer or manually



Dispersion by auto doser



Trial dyeing of first recipe



Unload



Normal wash



Hot wash with detergent



Finishing



Hydro



Drying



Compare with standard swatch



If ok



Send for buyer’s approval


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 engineers own procedure. This procedure is applicable for yarn or fabric dyeing.

In dyeing lab, the textile engineer should have deep knowledge about the shade matching.
