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.

The present invention discloses a method of constructing a solid slippery surface, belonging to the technical field of preparation of lubricating materials. The method of constructing a solid slippery surface comprises (1) constructing a metal oxide coating on the surface of a metal substrate by anodic oxidation, and then modifying the metal oxide coating using a low surface energy material to afford a superhydrophobic coating; and (2) fulling mixing photothermal nanoparticles and solid paraffin, followed by infusing the mixture onto the surface of the superhydrophobic coating to afford the solid slippery surface. The preparation method of the present invention is performed in a simple process and is environmentally friendly. The solid slippery surface constructed in the present invention has excellent photothermal and anti-icing performance, making some improvements in the field of copper metal anti-icing.

The present invention relates generally to wall repair compounds such as joint compounds, spackling compounds, and the like used to repair imperfections in walls or fill joints between adjacent wallboard panels. Particularly, the present invention relates to such a wall repair compound that comprises a dust-reduction additive that reduces the quantity of airborne dust generated when the hardened compound is sanded. The dust-reduction additive also synergistically imparts water resistance and adhesion to the wall repair compounds to which it is added. More specifically, in one embodiment, the dust-reduction additive is an emulsion comprising colloidally-protected, wax-based microstructures comprising paraffin that is chemically encapsulated by polyvinyl alcohol.
