In various embodiments, methods of treating a space to reduce a concentration of volatile organic compounds present in the space using chlorine dioxide are provided. A method can include application of aqueous and gaseous chlorine dioxide solutions within the space or to materials located within the space. Treatment of materials that emit volatile organic compounds with chlorine dioxide can reduce the emission rate or shorten the volatile organic compound emission cycle of the material. Soft surface substrates such as carpeting materials can be treated with chlorine dioxide to reduce volatile organic compound emission and/or to reduce the number of microorganisms present in the material.

A method for fiber modification provided in the present disclosure comprises steps: fibers react with a hypochlorous acid oxidant for development of antioxidant fibers, separate the antioxidant fibers from the hypochlorous acid oxidant and dry the antioxidant fibers for development of modified fibers which feature better oxidation resistance.

Provided is a recycling method of a polyester cotton blended fabric, including the following steps. A dye-containing polyester cotton blended fabric is put into an acidic aqueous solution containing an oxidizing agent for heating and soaking, so as to degrade the cotton in the polyester cotton blended fabric into powder, and decolorization is performed at the same time to remove the dye. After that, a polyester fabric and cotton powder are obtained by double filtration.

An article comprising a substrate having a stimuli-responsive hydrogel polymer functionalized to or associated with a surface. The stimuli-responsive hydrogel polymer is at least partially hydrated by an aqueous disinfectant solution comprising a disinfectant. The disinfectant is formed-prior to hydrating the stimuli-responsive hydrogel polymer. At least a portion of the disinfectant is taken up, stored, or released as an aqueous solution or a gaseous vapor upon interaction with a stimulus.

It is an object to provide a novel wet wiper in which a sterilization effect and a wiping/cleaning effect are maintained even when the wet wiper is stored for a long period of time. A wet wiper is provided which includes: a fabric; and a chlorine-based treatment agent included in the fabric, wherein the chlorine-based treatment agent includes at least one of chlorous acid (HClO.sub.2), chlorite ion (ClO.sub.2.sup.−), and chlorine dioxide (ClO.sub.2) as an effective chlorine component.
