A coated abrasive article () comprises: a backing () comprising polyester and having a major surface (); a tie layer () directly bound to at least a portion of the major surface (); and an abrasive layer () directly bound to at least a portion of the tie layer (), the abrasive layer () comprising abrasive particles () and at least one binder resin (). The tie layer () comprises an at least partially cured blend of, on a solids basis, from 50 to 99 parts by weight of at least one styrene-butadiene copolymer latex and from 1 to 50 parts by weight of at least one resorcinol-formaldehyde resin. A treated backing () comprising polyester having the preceding tie layer () directly bound thereto is also disclosed.

The present disclosure relates to multi-layer composite articles including at least two nonwoven web layers. Each or the layers may be a spunbonded web, and each may include biodegradable materials. The multi-layered composites of the present disclosure are particularly well suited for air filtration, as they can combine a high dust holding capacity with sufficient strength, dimensional stability, and a relatively low pressure drop.

Multi-layer, biodegradable composites for air filtration

An article () has a polyester film backing () and a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester film backing (). Another article includes a polyester backing (), a primer layer () including a carboxylated styrene butadiene copolymer crosslinked with a polyfunctional aziridine disposed on a major surface of the polyester backing (), and a phenolic layer () disposed on the primer layer () on a surface opposite the polyester backing (). The phenolic layer () can include abrasive particles (). Processes for making the articles are also described, as well as methods for abrading a workpiece and improving adhesion between a polyester film backing () and a phenolic layer () on the polyester backing ().

Articles including polyester backing and primer layer and related methods

A process and apparatus for producing a dimensionally stable melt blown nonwoven fibrous web. The process includes forming a multiplicity of melt blown fibers by passing a molten stream including molecules of at least one thermoplastic semi-crystalline (co)polymer through at least one orifice of a melt-blowing die, subjecting at least a portion of the melt blown fibers to a controlled in-flight heat treatment operation at a temperature below a melting temperature of the at least one thermoplastic semi-crystalline (co)polymer immediately upon exiting from the at least one orifice, and collecting at least some of the melt blown fibers subjected to the controlled in-flight heat treatment operation on a collector to form a non-woven fibrous structure. The nonwoven fibrous structure exhibits a Shrinkage less than a Shrinkage measured on an identically-prepared structure including only fibers not subjected to the controlled in-flight heat treatment operation, and generally less than 15%.
