  • Patent number: 4096311
    Abstract: Wipe-dry characteristics of non-woven, dry-formed webs are improved by a post-treatment process that adds water and a surfactant to the web followed by wet-working the web. The effectiveness of the surfactant for improving the wipe-dry capability is noticeably enhanced by working the web while it is still wet with the water and the surfactant. Preferred surfactant addition is from about 0.5% to about 3% by weight surfactant based upon the weight of the web.
