Abstract
A disinfecting cleaning wipe of stitch-bonded construction. The wipe includes a stitching substrate of fibrous nonwoven material having a mass per unit area of not more than 30 grams per square meter. A first plurality of stitching yarns is disposed in stitched relation through the stitching substrate in a pattern of substantially parallel linear stitch lines extending in a first direction across the stitching substrate. At least a second plurality of stitching yarns is disposed in stitched relation through the stitching substrate in a repeating zigzag pattern to define a first group of surface yarn float segments extending diagonally between stitch positions at opposing linear stitch lines. A disinfecting solution at least partially saturates the cleaning wipe.

A disinfecting cleaning wipe of stitch-bonded construction comprising:
- a stitching substrate of fibrous nonwoven material having a mass per unit area of not more than 30 grams per square meter;
- a first plurality of stitching yarns disposed in stitched relation through the stitching substrate in a pattern of substantially parallel linear stitch lines extending in a first direction across the stitching substrate, wherein the linear stitch lines are spaced apart from one another by a distance of at least 3 mm or greater;
- at least a second plurality of stitching yarns disposed in stitched relation through the stitching substrate in a repeating zigzag pattern to define a first group of surface yarn float segments extending diagonally between stitch positions at opposing linear stitch lines, wherein the second plurality of stitching yarns is characterized by a linear density greater than the first plurality of stitching yarns, wherein the stitching substrate of fibrous nonwoven material is spunbond polypropylene characterized by a mass per unit area of about 10 to 20 grams per square meter, wherein the linear stitch lines are spaced apart from one another by a distance of about 4 mm to 10 mm and wherein the first group of surface yarn float segments are formed from textured spun yarns and have a length of about 5 mm to 12 mm between stitches;
- and
- a disinfecting solution at least partially saturating the cleaning wipe.
