"Anti-Starch Covers are used to protect padding from constant abrasion as the rolls turn tightly against the chests. They protect the linen from the coarseness and irregularities of the padding. They keep dirt from the padding and prevent particles from adhering to the linen being ironed. They hold the padding assembly in proper position. Anti-Starch Covers are 9.0 (OSY) and are 100% woven aramid fiber with a starch resistant treatment. This cover is made exclusively for Tingue. "
