Abstract
A mop head comprising a bundle of fibers bound together to create mop head fabric. The fibers are composed of polyvinyl alcohol which is water soluble at temperatures above approximately 93.degree. C. The polyvinyl alcohol fibers are produced by a process of dope extrusion and which contain wetting and anti-blocking agent.
Claims12
A mop head comprising a bundle of fibers bound together to create said mop head fabric, said fibers comprising polyvinyl alcohol which is water soluble at temperatures only above approximately 93.degree. C., said polyvinyl alcohol fibers being produced by a process of dope extrusion and then treated with heat and stretching, the degree of crystallinity and the degree of orientation for the heated and stretched polyvinyl alcohol fibers are approximately 0.70 and 0.52, respectively, and wherein the water content of the polyvinyl alcohol fiber is kept at a value between approximately 1.5 to 15.0% (wt.), said polyvinyl alcohol having a degree of polymerization between approximately 1300 to 1500 being produced from greater than 99% saponified polyvinyl acetate.
A mop head comprising a bundle of fibers bound together to create said mop head, said fibers comprising polyvinyl alcohol, approximately 0.1 to 5.0% of an anti-blocking agent based upon the weight of the polyvinyl alcohol and approximately 0.1 to 2.0% of a wetting agent based upon the weight of the polyvinyl alcohol, said polyvinyl alcohol being characterized as being water soluble at temperatures only above 93.degree. C., said polyvinyl alcohol fibers being produced by a process of dope extrusion and then treated with heat and stretching, the degree of crystallinity and the degree of orientation for the heated and stretched polyvinyl alcohol fibers are approximately 0.70 and 0.52, respectively, and wherein said water content of the polyvinyl alcohol fiber is kept at a value between approximately 1.5 to 15.0% (wt.), said polyvinyl alcohol having a degree of polymerization between approximately 1300 to 1500 being produced from greater than 99% saponified polyvinyl acetate.
