摘要

PATENT APPLICATION OF Walter G. DeWitt Robert A. Gill METHOD OF PRINT BONDING NON-WOVEN WEBS IN 83-05 - ERS/rvp This invention concerns a process for preparing non-woven webs having a very soft hand and a high tensile strength. The process involved includes print bonding a non-woven web with a formaldehydefree binder having a glass transition temperature of about 5.degree.C to about 33.degree.C, then drying, curing and then calendering the non-woven web. The resultant non-woven web has a cross dimensional water wet tensile strength of at least 150 g/in and has a softness value of at least as soft as thermally bonded polypropylene. The invention is also concerned with a product produced by the above process.
