Systems and methods are provided that involve a subcritical water reaction to recycle the cellulose and polyester components of waste cotton and cotton/polyester blend textiles that would otherwise be discarded or disposed of. Specifically, the disclosed methods provide for treatment of the waste textiles to produce advanced materials including cellulose and terephthalic acid (TPA) with a low environmental impact. The cellulose and TPA that are produced are of a high quality allowing for production of regenerated cellulose and regenerated polyethylene terephthalate (PET) suitable for fiber spinning and textile applications.

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.
