The weight of the meltblown fabric is uneven in the width direction

As with spun-bonded non-woven fabrics, one can see the phenomenon of one line thin and one line thick in appearance.

Cause: Most melt-blown fabrics are single-row spinnerets. For example, if the holes are blocked at certain positions, the process is abnormal, and the melt pressure is uneven, and the weight will be uneven.
