Chemical Bonded

Chemical bonding refers to the application of a liquid-based bonding agent to the web to strengthen the adhesion between fibers. Chemical binders can also be used to improve characteristics including strength, softness, water resistance and fire retardance, depending on the intended end-use for the material.

There are several methods of chemical bonding, with the main four being print, spray, saturation and foam bonding. Saturation bonding in particular may affect the uniformity of the fabric, and in all cases an automated inspection system is recommended to monitor web continuity and surface quality.

Inspection systems will identify any surface flaws, allowing action to be taken to remove substandard product. It will also highlight web defects at an early stage, helping to maintain the continuous process. In this way it supports both quality and efficiency.
