treatments, however, must be reapplied periodically,
frequently after each cleaning, which imposes a
continuing maintenance burden. Permanent treatments
can be successfully applied to most fabrics. Only a
few fibers or fabrics are limited to renewable
treatments. Specify permanent treatment except
where the fiber type or other fabric characteristics
prohibit use of this type.
