The jointly developed 4.2m line is the 14th Trützschler ATB line for Wisdom-Greentech. The carding machine has a working width of 4.2m and a designed speed of 200 m/min. Compared with traditional 2.5m and 3m production lines, the production capacity is doubled. Compared with traditional 4.2m production lines, it further improves production efficiency while maintaining high product quality, reduces production costs, and significantly enhances product competitiveness.
