Rayon blended yarns are superior in absorbency and do not require a break-in period. Rayon yarn is also more bleach resistant and mildew resistant than cotton yarns. Rayon is more durable because it is produced with 100% long staple synthetic fibers. Rayon yarn can be used effectively for all wet mopping applications including economical wax applications. Cut-End style mops are not machine launderable.
