Nonwoven disposable wiper intended primarily for industrial applications and having a reduced tendency to accumulate metal chips or other small, sharp foreign objects. The wiper results from a combination of a meltblown microfiber web laminated to at least one web of interconnected aligned split filaments, such as a fibrillated thermoplastic film or foam. The combination is pattern bonded and includes a surfactant for improved wiping properties. The combination of the split flamentary web and microfiber web results in increased safety since injuries due to metal chips picked up by the wiper material are minimized. This is accomplished without significant deterioration of the wiping properties of the meltblown material.
