For many years, textile mills have used strong chemicals to remove old emulsion from rotary screens. Yes, the chemicals clean the screens – but they also bring many problems that affect workers, machines and the environment.
Let’s understand these problems in a simple and clear way.
1 Chemical Cleaning Is Unsafe for Workers
The most commonly used chemicals include very strong acids. These can:
- burn skin
- harm eyes
- create dangerous fumes
- affect breathing
Many of these chemicals are already banned in Europe because of their health risks. Workers who handle these chemicals daily face long-term health problems.
2 Screens Become Weak and Break Faster
Chemicals slowly damage the nickel surface of the rotary screen.
This causes:
- mesh becoming thin
- screens losing strength
- print quality getting poor
- screen life reducing
In short: you spend more money replacing screens again and again.
3 The Environment Gets Damaged
When chemical waste is washed away, it pollutes water and soil.
This increases:
- disposal cost
- risk of government penalties
- negative environmental impact
Today, textile brands expect mills to follow clean and safe processes. Chemical cleaning does the opposite.
