What is sandwashing?
As one of the methods used to produce clothing that is soft to the touch, few methods make use of natural methods as sandwashing. Here is some background on the process of sandwashing, and how this method helps to produce garments that we love to wear. Sandwashing is basically a garment washing process that is intended to remove any residual stiffness from the material used to make the clothing item. The aim of the sandwashing is not to produce a garment that will wrinkle easily. Rather, the focus is on ensuring that the clothing feels soft to the touch. After being treated for softness, the sandwashed garment can still undergo anti-wrinkling treatments and manage to retain the soft-brushed feel created by the treatment. The sandwashing treatment itself originally involved the use of very fine lava rocks. A quantity of the lava rocks is placed into a container along with the finished garment. The container is then rotated, allowing the rocks to gently abrade the fibers of the garment.
