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 with fibers added and, on one side, a lightweight layer of generally continuous filament thermoplastic fibers having a larger average diameter with a microfiber layer on the other side. 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 compounents are preferably treated with a surfactant. The preferred combination of a layer of meltblown polypropylene microfibers with fibers added having on one side a spunbonded polypropylene filament layer and on the other a microfiber layer is particularly effective as an all-purpose wiper.
