There are great changes in color and light
1. Reason:
The main reason for the color change is the deepening effect of fluorine-containing resin. This is also a phenomenon that cannot be completely avoided during the waterproofing process. Discoloration is a normal phenomenon and usually becomes darker because a waterproof film is formed on the surface, causing refraction, so the color looks darker.
2. Main countermeasures:
To solve the color and light change, you can confirm the degree of color and light change through preliminary tests, and then carry out color matching; replenish the newly prepared working fluid as soon as possible during processing (it is better to have an automatic liquid adding device) to prevent head and tail color difference.
The above are the problems that often occur in waterproof and oil-proof finishing. We selected a variety of waterproof and oil-proof finishing agents for testing, and found that by adopting the above measures and selecting excellent waterproof and oil-proof finishing agents (such as Japan’s Mingcheng series), the above problems were basically solved and the waterproof and oil-proof effect was improved. The customer satisfaction rate for waterproof orders is high. In short, choosing the appropriate waterproof and oil-proof finishing agent will provide a good foundation for the waterproof and oil-proof finishing of fabrics; during the finishing process, the processing cloth, working fluid and processing conditions are the guarantee for obtaining good waterproof and oil-proof effects.
