What Makes Clothes Static?
Static electricity results from friction between two different materials that come in contact with each other in a dry environment.
How to De Static Silk Clothes Easily?
1) Mist it with H₂O
Since static build-up can only happen in a dry environment, adding a little moisture can help you solve your problem. You can invest in a spray bottle to help you out. All you have to do is spray some water on your clothing before you go out, just enough to dry before you head out.
2) Apply moisturizer to your body before you get dressed
Try to apply lotion to your legs or any other part of your body that experiences static cling. Please be sure to allow the moisturizer to be completely soaked in before dressing. (If your skin is greasy, it may leave a stain!)
3) Use a metal hanger (a safety pin or metal thimble work may also be OK)
Run a metal hanger on the surface and inside any clothing article. This will reduce the electrical charge by transferring the electron charges on the clothes to the metal hanger. But other small metal objects can also do the trick.
