Abstract
Abstract A glass fiber wool binder composition comprising a phenolic resole resin, animal bone glue, a sulfite process lignin and dicyandiamide is disclosed. When a binder composition of this invention is employed on glass fibers to produce uncured glass fiber wool, the uncured wool exhibits improved integrity, thus facilitating alignment of uncured wool in mold contours and the production of molded products.

Claim 2
Dependent Claim
46 words
At least one glass fiber at least a portion of the surface of which is in contact with a residue produced by removing water from an aqueous composition comprising: (1) a phenolic resole resin, (2) animal bone glue, (3) a sulfite process lignin and (4) dicyandiamide.
Claim 3
Dependent Claim
26 words
