<p>Title: DYE-RECEPTIVE POLYOLEFINS AND POLYOLEFIN FIBERS Polyolefin compositions are described which can be dyed by conventional dyeing techniques. Such polyolefins comprise a blend of (A) a polyolefin and (B) a dye-receptive amount of at least one metal sulfonate which is soluble in the polyolefin when melted, and which sulfonates are characterized by the formulae (I) (R' Ar SO3)x M (II) wherein R is an aliphatic group, R' is an aliphatic group containing at least about 8 carbon atoms, Ar is an aromatic group, M is an alkali or alkaline earth metal, n is at least 1. y is equal to 1 when M is an alkali metal and 1/2 when M is an alkaline earth metal, and x is equal to the valence of M. The preferred sulfonates are those represented by Formula (I) and especially wherein M is sodium. In particular, it has been found that films and fibers prepared from such polyolefin comosition, and more particularly polypropylene compositions, are readily dyed with common dyes to provide deep shades and fastness.</p> |
