NONWOVEN BINDERS WITH HIGH WET/DRY TENSILE STRENGTH RATIO |
摘要 |
This invention is directed to an improvement in a crosslinkable vinyl acetate/vinyl versatate based polymeric binder for use in nonwoven applications. The improvement in the binder for nonwoven and, particularly premoistened wipes, resides in a polymer comprised of vinyl acetate and vinyl versatate produced by either of the methods: batch polymerization where polymerized units of an in situ or internal crosslinking (polyolefinically unsaturated) monomer are incorporated into the polymer; or, delayed addition of vinyl versatate where the vinyl versatate is polymerized into the polymer by delayed addition such that vinyl versatate rich polymer segments are formed; and, preferably, polymerized units of a polyolefinically unsaturated monomer are incorporated into the polymer. |
