What chemical dissolves sewing threads?

Sewing threads, often made from polyester, nylon, or cotton, can be dissolved by specific solvents. For synthetic threads like polyester and nylon, solvents such as acetone or dichloromethane may be effective. For natural fibers like cotton, stronger acids or bases, such as sodium hydroxide, can dissolve the material. However, care should be taken when using these chemicals, as they can be hazardous and may damage other materials.
