ABSTRACT:
A textured, continuous, multi-filament polyester yarn or fabric has a plasticizer incorporated onto the surface thereof and/or into the interfilamentary structure thereof either during the texturizing process or after the yarn has been made into a gauze-like fabric substrate. Because of the plasticizer, the gauze is enabled to be laminated to a vinyl sheet as it is formed. The plasticizer is characterized in that it is compatible with both the vinyl and the polyester, it softens the vinyl to receive the polyester gauze, it has a viscosity in the range of 25-105 centistokes (cs), and it swells or plasticizes the vinyl to such an extent that the polyester gauze becomes imbedded therein and affixed thereto to effectively bond the gauze to the vinyl. The gauze fabric substrate, when laminated to the vinyl sheet material, gives the vinyl sheet both enhanced strength and stability.
