## Abstract

Compositions and articles with improved flame properties and fabric with improved melt dripping properties is disclosed. Reduced melt dripping can prevent injuries. Methods for making and using such compositions, articles and fabric are disclosed.

## Claims

### Claim 1

A composition comprising: a plurality of nylon-based polymer fibers, wherein one or more of the nylon-based polymer fibers are melt blended with a polymer comprising the following groups:
and one or more of the remaining nylon-based polymers comprise a first functional group and one or more of the remaining nylon-based polymers comprise a second functional group, the second functional group being different from and complementary to the first functional group; wherein one or more of the nylon-based polymers crosslink upon exposure to flame, and wherein the first functional group and the second functional group are selected from the following functional group combinations: amine and epoxide, amine and anhydride, amine and isocyanate, amine and aldehyde, amine and alkyl halide, amine and alkyl sulfonate, and amine and thiol.
