Measuring spunlaced nonwovens

For example, if the weight does not correspond to the specifications, this can lead to errors in functionality, but also to unnecessarily high raw material consumption. A fleece that is too light for medical masks may no longer be able to meet all safety standards and thus become a health hazard. Nonwoven webs that are used as supports for operating tables are also typical spunlaced nonwovens. If this type of product is too heavy, it does not affect function and safety. However, more resources are wasted than actually needed. The result: rising costs and a higher burden on the environment. The same applies to the residual moisture in the product. If the product is too moist, there is a risk of mold growth, and if the fleece is too dry, the energy consumption in the line is too high.

The advantages of quality control are obvious: If critical parameters are systematically controlled and regulated, this is reflected in higher fabric quality. This means less rejects and less consumption of raw materials. This not only saves manufacturers time, but also money.

The necessary measurement and control tasks are performed by the modular quality control system Qualiscan QMS »  from Mahlo. The cross direction profile of the measurement is displayed over the entire fabric width by means of traversing sensors. Depending on the application, the infrared sensors Infralot IMF or Infrascope NIR are used.

Mahlo has already successfully implemented many such applications and offers the user a perfect tool with high measuring accuracy and easy handling. Our technical service ensures that the desired measures are implemented 100%. Not only can products with "zero defects" be manufactured continuously, but quality, efficiency and profit can also be increased in the long term.
