Abstract
Abstract Sterile package moist woven cloth towel and method for producing same in hermetically sealed packages. The invention comprises inserting a small woven cotton cloth towel, such as of terry cotton, into a liquid impervious envelope, injecting a sufficient volume of liquid into the envelope to impregnate the towel, hermetically sealing the envelope and finally exposing the envelope to sufficient radiation to cause sterilization of the liquid-impregnated towel therewithin. The woven cloth is capable of laundering for subsequent use in wet or dry condition.
