Examples of the plant Productivity, which changes very much according to the fabric type, their cleannes degree and weight:
- fabric denim, width1900 mm 400/450 gr. linear meter, not desized, - speed 10/11 meter/min.
- fabric denim, width 1900 mm 400/450 gr linear meter, desized - speed14/15 mt/min.
- shirting fabric, width 1800 mm 150/200 gr. linear meter - speed 18/20 mt/min.
The line is located in Italy and can be inspected in running.
