STABILIZATION OF LOOPED FABRIC SURFACES BY FINE-SCALE EMBOSSING
A fabric made of yarns interlooping with each other or passing through an inner layer at looping intervals. The fabric is embossed with a micro-pattern extending into the yarns or into a layer underneath the fabric. The micro-pattern contains a pre-defined pattern of a plurality of binding points attaching the yarns to the inner layer or to the added underlayer. This micro-pattern has an inter-point spacing between adjacent binding points that is less than the interlooping intervals. The fabric can also be embossed with a macro-pattern separate from and coarser than the micro-pattern. The macro-pattern establishes a desired aesthetic in the fabric, and the micro-pattern does not interfere with the desired aesthetic.
Cleaning article with differential sized tow tufts
A cleaning article defining an XY plane and a Z direction perpendicular to the plane. The cleaning article has discrete tufts of tow fibers bonded to a carrier sheet by primary bonds. The discrete tufts have secondary bond lines external to the tufts. The secondary bond lines interrupt the Z-direction thickness of the tufts, to provide channels for improved collection and retention of debris from a target surface. The tufts are created by slits between the primary bonds and secondary bonds, which yield plural tuft sizes. The slits may be transversely unequally spaced between adjacent bonds.
