A recently granted patent (Publication Number: US11771790B2) describes a pre-saturated disposable disinfecting wipe that offers improved coverage and durability. The wipe consists of a microfiber cloth with a substrate and microfiber yarn attached in parallel rows and stitches. The cloth is saturated with a liquid disinfecting formulation.

The patent claims that the pre-saturated disposable disinfecting wipe has a single-touch two-minute wetness coverage of more than 100 square inches and an abrasion resistance of more than 10 cycles. Additionally, the microfiber yarn comprises between 100 and 300 filaments and has a denier (a unit of measurement for the linear mass density of fibers) between 50 and 150.

The patent also mentions that the liquid disinfecting formulation can include various ingredients such as alcohol, quaternary ammonium chloride (QUAT), chlorine bleach, citric acid, hydrogen peroxide, or peracetic acid.

The microfiber yarn is attached to the substrate using straight stitches that are flush with the first and second faces of the substrate. Alternatively, the microfiber yarn can be stitch-bonded onto the substrate.

The weight of the microfiber cloth can range from 10 g/m2 to 150 g/m2, with a preferred range of 45 g/m2 to 65 g/m2. The cloth is saturated with the liquid disinfecting formulation in an amount between 3.5 times and 4.5 times its dry weight.

The patent also includes methods of manufacturing the pre-saturated disposable disinfecting wipe. One method involves attaching the microfiber yarn to the substrate and then saturating the cloth with the liquid disinfecting formulation. Another method involves saturating a pre-existing microfiber cloth with the liquid disinfecting formulation.

Overall, this patent describes a pre-saturated disposable disinfecting wipe with improved coverage, durability, and liquid release percentage. The wipe can effectively keep a surface area wet for more than 2 minutes after a single application. The use of microfiber yarn and various disinfecting formulations enhances the wipe's effectiveness in disinfecting surfaces.
