Non woven applications : woven fabrics
Thermobonding belts, card exit belts, …
Dollfus & Muller manufactures different woven fabrics for non woven manufacturing. Its main products are for the thermobonding ovens and nonwoven cards.
Thermobonding process bonds the fibres together in order to create a pad of fibres which is used afterwards in bed furnishing, winter clothes ,…
This process requires high temperature (150 up to 200°C / 300 up to 380°F) which melts the fibres together. This process uses two belts which create pressure on the pad. The process itself has two stages : the high temperature stage to bond the fibres and a cooling chamber at the end of the process (50°C / 100°F) in order to fix the fibres.
These thermobonding conveyor belts are used on the following machines : Santex, Fleissner, Schott & Meissner, Aztec, Bombi,…
The main other woven fabrics for non wovens are antistatic belts, drylaid belts, spunlaid belts, wetlaid belts. The card exit belt is for instance for machineries such as Thibeau cards (NSC Nonwoven).
