Method of Manufacturing Headlining Using Moisture-Curing Adhesive and Headlining Manufactured Thereby
20230130842 · 2023-04-27 ·

Disclosed herein is a method of manufacturing a headlining, using a moisture-curing adhesive that can be molded at a relatively low temperature and enables energy saving by not requiring a condition in which bonding surfaces are preheated to an excessively high temperature. A headlining manufactured thereby the same method is also disclosed. The method includes coating a fabric with a moisture-curing adhesive, curing the moisture-curing adhesive by spraying water onto the moisture-curing adhesive, forming a headlining member by putting the fabric coated with the moisture-curing adhesive on a substrate after the curing, and pressing the headlining member so that the fabric and the substrate are bonded to each other and the headlining is shaped at the same time, after the forming.
