    摘要： 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 1×106 Daltons to 1×107 Daltons. 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 1×106 Daltons to 1×107 Daltons, and a polycarboxylic acid.

    摘要： Aqueous binder compositions with reduced rates of salt precipitation are described. The compositions may include a carbohydrate and a sequestrant for sequestering one or more multivalent ions (e.g., Ca2+, Mg2+, Ba2+, Al3+, Fe2+, Fe3+, etc.). The sequestrant reduces a precipitation rate for the multivalent ions from the aqueous binder composition. Methods of reducing salt precipitation from a binder composition are also described. The methods may include the steps of providing an aqueous binder solution having one or more carbohydrates. They may also include adding a sequestrant for one or more multivalent ions to the aqueous binder solution. The sequestrant reduces a precipitation rate for the multivalent ions from the binder composition.
