Textile deepening principle: By using resin or silicone oil to make the textile surface unevenly so whenwe changing the direction of the reflected light it will have deepened effect.
The law of reflection of light indicates that the incident point is relatively flat.
When the surface is uneven, the reflection of light amount to detection point is reducing so the visual sense will make the textile looks darker.
The components of deepening agent are resin or silicone oil, due to different concentration and condition the carry out also differently. It’s necessary to take continuous experiment to get the perfectly usage of working fluid concentration from the beginning to working for a while. How much differences and when shall they need to refill the working fluid to keep the same concentration?
Here’s the report of ZSB continuity experiment as below:
1. Equipment
a. Pad JMU504A
b. Bakeer Rapid No.7012
c. Electronic balance YP-1002N
d. Datacolor 600
2. Working Liquid 100ml
a. Deeping agent ZSB 30g/L
b. Softener RRJ 20g/L
c. Disperse agent 570-C 5g/L
3. Material: PES
4. Experimental conditions: Rolling pressure: 0.4MPa(set)
Pick up (50-60%)
Bake Temp: 170°Ctime : 60S
Computer colorimetric data: (light source D65)
Un-deepened cloth sample as standard

The result shows the concentration of the working fluid must be adjusted before rolling the 8th piece of fabric otherwise the deepening effect will not keep consistently. However, we still need to work on the tests to find when the perfect timing during the production.
