Abstract
A mop head has a fitting, a coupler, and string. The fitting couples to the end of a handle. The coupler attaches the string to the fitting. The string is arranged in multiple loops that depend from the fitting. The string itself is made of a foam core and a protective filament covering. The foam is of the open cell type for absorbency and wringability. The filament is braided or knitted so as to completely encircle the core and to provide openings therethrough in order to allow access to the core. The covering protects the core from tearing and other mechanical damage, while maintaining the porosity of the overall string.
Claims12
A string, comprising:
- a) an elongated core made of solid foam, the foam being of the open cell type and being absorbent, the core having a length;
- b) a porous covering encircling the core for the length of the core, the covering being formed from at least one filament, the covering having openings therethrough so as to allow access to the core from an environment around the string with portions of the core being exposed to the environment around the string by way of the openings;
- c) the string being capable of being stretched in the direction of the length of the core, with the covering having a greater breaking strength than the core.
