Improvements in tuft bind and/or elongation of tufted carpet may be achieved by selecting, as components of a tuft bind adhesive, one or more of: i) a polyol component comprising a low or ultra-low unsaturation polyoxypropylene polyol optionally containing up to 30 weight percent oxyethylene moieties, and ii) a chain extender component comprising 2-methyl-1,3-propanediol.

Polyurethane carpet backings with improved tuft bind

Tufted carpeting can be manufactured employing polyurethane adhesives and cured face up without dripping, when one or more drip-reducing process steps of adding a non-Newtonian thickener to the adhesive or forming a viscosified or cured film on the outer surface of the adhesive are practiced prior to entry of the greige good into the curing oven.
