METHOD AND APPARATUS FOR PREPARING A FIBROUS BATT |
摘要 |
A process for providing a relatively smooth, tough, elastomeric coating over one surface of a fibrous batt employs a heated ironing surface which engages an uncured coating of a composition of cross-linkable elastomeric aqueous emulsion applied as a foam or froth to an exposed surface of a fibrous batt. The heated belt causes dewatering and cure of a film of the coating which is in contact with the ironing surface. The fibrous batt thereafter is heated in a curing oven to drive off substantially all of the moisture and substantially cure all of the elastomeric coating composition. The resulting coated fibrous batt has a smoother and tougher surface than similar batts formed from similar compositions without the interposed ironing treatment. A preferred ironing element comprises a continuous stainless steel belt. |
