Abstract
A method of forming a binder composition includes providing a urea-formaldehyde resin and combining one or more starch compounds with the urea-formaldehyde resin to form a starch modified urea-formaldehyde resin. The one or more starch compounds may be combined with the urea-formaldehyde resin so that the starch modified urea-formaldehyde resin includes about 1 wt. % to about 10 wt. % of the one or more starch compounds.
Claims20
A non-woven fiber mat comprising:
- a plurality of fibers that form a fiber mesh, the fibers of the plurality of fibers having:
- fiber diameters in the range of 12 to 17 microns;
- and
- fiber lengths up to about 3 inches;
- and
- a binder composition applied to the fiber mesh to bond the plurality of fibers together, the binder composition comprising:
- a starch modified urea-formaldehyde resin including:
- a urea-formaldehyde resin;
- and
- one or more starch compounds combined with the urea-formaldehyde resin to form the starch modified urea-formaldehyde resin;
- wherein the one or more starch compounds are combined with the urea-formaldehyde resin so that the starch modified urea-formaldehyde resin includes about 1 wt. % to about 10 wt. % of the one or more starch compounds.
