The weave design offers a uniform distribution of pulp fibers and provides outstanding drainage capacity as a result of high top surface open area. The large diameter of weft yarns and long crimp on machine side provides excellent wear resistance and runability. The 2.5 layer forming fabric has the features of excellent pulp fiber support, paper sheet formation and high drainage.
Advantages
Improvement in sheet formation, smoothness.
Reduction of wire mark.
Easier to clean.
Larger diameter yarns in wear side to improve life potential.
Application
2.5 layer forming fabric's weaving effect greatly increases the fiber support index due to the addition of a fine weave at the top. The ratio of the top and bottom wefts is 2:1. It suitable for paperboard,newsprint,writing paper,tissue paper,printing paper,kraft paper.
