Abstract
Fiber-containing composites are described that include woven or non-woven fibers, and a binder that holds the fibers together. The binder may include the reaction product of a starch and a polycarboxylic acid. The starch has a weight average molecular weight that ranges from 1×10Daltons to 1×10Daltons. The fiber-containing composite has an unaged tensile strength of greater than 4.0 and an aged tensile strength greater than 3.0. Also described are methods of making the fiber-containing composites. The methods may include applying a binder composition to fibers to form coated fibers, measuring a moisture content of the coated fibers, and curing the coated fibers in a curing oven to form the fiber-containing composite. The binder composition may include a starch having a weight average molecular weight that ranges from 1×10Daltons to 1×10Daltons, and a polycarboxylic acid.
