ABSTRACT OF THE DISCLOSURE Nonwoven wiper having improved absorbency characteristics and streak free wiping properties having a laminate construction including a relatively high basis weight middle layer of meltblown thermoplastic microfibers and, on either side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter. These wipers are strong, fabric-like, and are useful for a wide variety of applications including industrial uses, food services, as well as many others. The continuous filament layers provide strength and low lint properties while the combination exhibits improved wiping characteristics. The laminate is preferably bonded by application of heat and pressure and the individual components are preferably treated with a surfactant. The preferred combination of a layer of meltblown polypropylene microfibers having on either side a spunbonded polypropylene filament layer is particularly effective as an all purpose wiper.
