Abstract
Abstract Methods of controlling the migration of resin binders in the manufacture of bonded nonwoven fabrics from fibrous webs comprising the use of a resin binder composition comprising: (1) a synthetic resin; (2) a water soluble, polymeric, carboxylic thickener; and (3) a metal amine, complex coordination compound capable of releasing ions of said metal to control the total migration of the resin binder during its deposition on the fibrous web.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
144 words
A colloidal synthetic resin composition for application under controlled migration conditions to porous, absorbent materials which comprises a stable, colloidal aqueous dispersion having an alkaline pH comprising: (1) from about 0.1 to about 60 percent by weight on a solids basis of a colloidal synthetic resin: (2) from about 0.05 percent by weight to about 7 percent by weight, based on the weight of said colloidal synthetic resin of a water-soluble, polymeric carboxylic synthetic resin thickener; and (3) from about 0.01 percent by weight to about 5 percent by weight, based on the weight of said colloidal synthetic resin of a metal ammine complex coordination compound, having the formula Me (NH3)xY wherein Me is a metal, x is a whole number from 2 to 8, and Y is an anion, said metal being selected from the group consisting of chromium, nickel, zinc, and copper.
