AI Technical Summary

Technical Problem

Existing paper-making processes face challenges in effectively reducing adhesion between a tissue web and structured fabrics, particularly in Through-Air-Drying (TAD) processes, which affect machine runnability and sheet quality.

Method used

A composition comprising quaternized long-chain imidazolines and long-chain fatty acids, combined with emulsifier agents and lubricant oils, is applied to the TAD fabric surface to enhance the release of the tissue web, utilizing intermolecular interactions for improved anchoring and lubrication.

Benefits of technology

The composition significantly reduces paper adhesion, enhancing machine runnability and sheet quality by promoting better spreading and retention of lubricant oil on the fabric surface, thereby improving the release performance.
