Image Analysis for Non-woven Inspection

This article focuses on the importance of image analysis for the inspection of non-woven materials. 

Advances of modern vision systems

As quality control issues and standards grow in the non-woven industry the importance of inspection uniformity is undeniable. The old approach of manual inspection which is a subjective, tedious and time-consuming approach were traditionally employed to identify fabric defects. This older approach raised huge concerns over quality and efficiency, nowadays along with the rapid development in technology, image-based inspection has been widely employed for image processing and texture recognition on nonwovens, textiles and engineered fabrics. 

Modern fast and accurate vision systems need to be employed for characterization of non-woven material. Some of the common fibre characteristics that modern vision systems can identify include:

  • Blend irregularity in yarns.
  • Pile-fibre distribution in silver-knitted fabrics.
  • Non-woven structure characterization.
  • Carpet texture evaluation.
  • Fabric testing.

Key defects that a modern vision system can identify:

  • Contamination detection.
  • Fish eye detection. 
  • Broken filament detection.
  • False color fibre detection.
  • Scratch detection.
  • Dent detection.
  • Roping detection.     non-woven_defects..jpg
  • Oil stain detection.
  • Wrinkle detection.
  • Drop detection.  
  • Coating defect detection.
  • Streak detection.
  • Holes by fibre break detection.
