Abstract
Disclosed is a disposable floor mat with improved wet soil absorbency comprising a primary backing and flocked or tufted fibers, the bases of which are adhesively or mechanically attached to said backing. The mat is characterized in that it has a surfactant disposed thereon which improves the wet soil absorbency in the mat with limited (controlled) surfactant mobility. The controlled surfactant mobility minimizes the transfer (tracking) of the disposed surfactant onto the permanent floorings.
Claims12
A fibrous floor mat comprising:
- a primary mat backing and assembled fibers, the bases of which are attached to said primary backing;
- characterized in that said fibrous mat has a surfactant disposed thereon at a level of less than 0.5 surfactant/mat weight ratio percent, wherein said mat has a Surfactant Mobility Test contact angle value of from 75.degree. to 86.degree., whereby a minimal amount of surfactant and wet soil would be tracked off the mat, and wherein said mat has significantly improved wet soil absorbency performance over a fibrous floor mat without any surfactant disposed thereon according to the Wet Soil Absorbency Test.
