Lab Dip:
A lab dip is a swatch of fabric test dyed to hit a color standard. It is a process by which buyer’s supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of spectrophotometer. Lab dip plays an important role in shade matching & this is an important task before bulk production. In previous article of this author we have to learn on flow chart on dyeing lab.
There are different matching systems followed in Labs. They are :
 |
| Lab dip |
- Tube light matching.
- Sun light matching.
- Ultra Violet matching.
- Sodium light matching (show room).
The main objectives in lab dip are as follows:
- To calculate the recipe for sample dyeing.
- To compare dyed sample with swatch by light Box or Spectrophotometer.
- To calculate revise recipe for sample dyeing.
- Finally approved Lab Dip (Grade: A, B, C & D)
Lab dip plays an important role in dyeing process. Bulk dyeing process completely depends on the lab dip development work. Lab dip is completely managed as the following sequence.
