VapConHT Steam Oven

The steam oven manufactured by SCHOTT & MEISSNER is used in nonwovens bonding by means of phenolic powder or epoxy resin for either semi-curing or assisting in full-curing. The steam penetrates the fibre package and the thermal energy of the steam is used to activate the phenolic resin; this results in a first cohesion between powder and fibre. A double belt oven (TopConLP; AirConTS) is downstream to the steam oven in the full-curing process. Due to the pre-activation of the powder in the steam oven, the fabric web can be hardened in the double belt oven. A relevant thickness calibration can be undertaken via the double conveyor belt.
