Quality Inspection and Defect Detection for Nonwovens
topic
Nonwoven quality inspection uses inline machine vision systems with line scan cameras detecting holes, contamination, bond defects, and weight variation from optical transmission or reflection imaging, supplemented by offline laboratory testing of basis weight, tensile strength, elongation, air permeability, and application-specific functional properties from samples taken at defined intervals to verify that production rolls meet all specification parameters before shipment.
Role
Ensures that nonwoven fabric rolls delivered to converting operations meet all specification requirements through continuous online defect detection that identifies and maps defect locations within each roll for selective rejection in converting, combined with offline sampling that verifies mechanical and functional properties that online sensors cannot measure, providing the complete quality assurance coverage required for high-speed converting operations using nonwoven raw materials.
