One or more aspects of the present disclosure are directed to aqueous solutions that can be used to make substrates such as an article that can inhibit or limit one or more sources of odor. In an aspect, the aqueous solution can include one or more components, where one of the components is an inhibiting agent that can function to inhibit or limit the sources of odor in an article such as a textile.

An object of the present invention is to provide a sewing thread treatment agent, and a sewing thread, each achieving low friction properties across a wide range of sewing speeds. As a solution, a sewing thread treatment agent is provided, which is characterized in that it contains a hydroxy-terminated polydimethylsiloxane (A), a nonionic surfactant (B), and at least one type of wax (C) selected from paraffin wax, oxidized paraffin wax, polyethylene wax, oxidized polyethylene wax, and carnauba wax.

A resin composition containing a) a resin, and b) a cellulose fiber composite having a carboxy group in the cellulose molecule, wherein an aldehyde group content is 0.20 mmol/g or less, and wherein the cellulose fiber composite contains a modifying group bound to one or more members selected from a carboxy group and a hydroxyl group. The resin composition of the present invention can be suitably used in various industrial applications such as daily sundries, household electric appliance parts, and automobile parts.
