A forward-link power control method is disclosed. The crosslinked particles are prepared by activating crosslinkable groups on synthetic polymer molecules, where the crosslinkable groups are inert until activated and, when activated, undergo an irreversible intramolecular crosslinking reaction to form crosslinked particles. The cloth may have a first configuration wherein the cloth is retracted substantially into the cover member, and a second configuration wherein the cloth is extended substantially out of the cover member without becoming detached therefrom.
