Demands on the thread wetting system
Water delivery rate
Depending on the count, the following water delivery rates must be available per thread position for wetting the thread:
| … 500 dtex | 0.8 … 1.5 l/h |
| … 2000 dtex | 0.8 … 2.5 l/h |
| … 5000 dtex | 1.5 … 3.5 l/h |
Water quality
In order to prevent damaging or scaling of the jets, the water of the thread wetting system must be filtered and softened.
