Zero defect production of nonwovens, membranes & filtration materials

High-performance nonwovens and membranes are used in a wide range of consumer and industrial goods. Often in highly technical or sensitive areas, such as medical or hygiene products, which are subject to specially defined quality standards. To meet these standards, quality assurance in production is essential. The SMASH inline inspection system ensures the highest product quality at every stage of production. The reliable system precisely distinguishes between contamination or material defects and ensures that only flawless products are delivered to your customers.

Nonwovens

Quality defects can occur in various nonwoven manufacturing processes, including spunbond, spunlace, meltblown, airlaid and wetlaid. In the spunbond process, defects can arise from issues such as inconsistent fiber feed, uneven die temperature, or insufficient cooling. This can lead to streaks, holes, clumps, or poor uniformity. For spunlace, defects may arise from inadequate water pressure or temperature control, inconsistent web tension, or uneven fiber distribution. This can cause pilling, linting, or holes.

In meltblown, defects can occur due to irregularities in the polymer feed rate, shot particles, poor air flow control, or inadequate filtration. The result can be filament breaks, uneven fiber distribution, pinholes, and poor web formation.

In airlaid, defects can arise from issues such as inadequate fiber blending, bale strapping, poor web formation, or insufficient adhesion. This may result in weak bonding between fibers, uneven thickness or low density. With the wetlaid process, defects can result from poor fiber distribution, insufficient water pressure, or insufficient bonding. These can result in poor web formation, uneven density or insufficient bonding, thin areas, and holes.

MSTAR inspection solutions ensure the highest quality in all nonwoven manufacturing processes by detecting and classifying defects before slitting/rewinding as well as evaluating the rolls for conformity. This reduces waste as users can immediately correct process-related defects. Color cameras, real-time Multi-Scan Technology, and uniformity analysis enable the detection of even the smallest defects at high speeds. The solutions make invisible defects visible, identify and eliminate critical defects with AI classification, and offer condition and health monitoring.
