Wicking occurs when a fabric soaks up oils and fluids quickly like the wick of an oil lamp.
The absorption of liquids or oils by the bottom fabric of the conveyor belt can bring about problems like delamination of plies and edge separation. Pathogenic microorganisms may also penetrate the fabric through capillarity, allowing them to flourish off the surfaces of the belts, thus making the belts difficult to clean.
Esbelt´s wick resistant belts are made with a specially treated fabric that are resistant to fluid penetration to solve these problems. These are belts with ´´W.impreg´´ or ´´WP´´ fabrics. They pass the Wicking Test G11, a concept defined in an FDA guideline in June 2011 under chapter G, section 11. According to the test, conveyor belts with fabric support should be dipped into water mixed with a food colorant: color penetrations higher than 1mm are not acceptable.
Esbelt´s ´´wick resistant´´ belts prevent the absorption of water and oils, enhancing the hygiene in food applications. Even though the fabric is not covered by thermoplastic, its wick resistant property protects the fabric and enhances hygiene in food applications.
