1. A process of making a non-woven glass fiber mat, the process comprising the steps of:
forming an aqueous dispersion of fibers;
passing the aqueous dispersion through a mat forming screen to form a wet mat;
applying a carbohydrate binder composition to the wet mat to form a binder-containing wet mat; and
curing the binder-containing wet mat to form the non-woven glass fiber mat,
wherein the carbohydrate binder composition comprises a carbohydrate, a nitrogen-containing compound, and a thickening agent, and wherein the carbohydrate binder composition has a Brookfield viscosity of 7 to 50 centipoise at 20° C. as measured with a Brookfield viscometer using spindle 18 at 60 rpm.
