How to control the uniformity of needle-punched non-woven fabrics?

How can a needle-punched non-woven factory control product unevenness? Needle-punched non-woven fabrics are made by carding polyester fiber raw materials through a carding machine and then overlapping and needling multiple layers of raw materials. During the carding process, sometimes due to uneven carding, there will be a slight difference in product weight, but overall the difference will not be too much. Then the quality of the product has a lot to do with the quality of the equipment and the technical level of the technicians.
