A new dryer process for wide nonwoven webs has been introduced by Glenro, Paterson, NJ. The process uses a waterbased silicone finish on a spunbonded polyester nonwoven web that is 210 inches wide. The dryer uses high velocity hot air impingement nozzles mounted beneath the product to apply hot air to the web at a right angle. Hot air impingement breaks through the material to vaporize liquids in the coating or finish. High velocity hot air impingement is used in applications where large quantities of water must be removed from a saturated or coated product. The dryer system measure 11.75 x 21 x 11.8 foot and is made from aluminized steel.
