ABSTRACT OF THE DISCLOSURE Wiper comprising a matrix of nonwoven fibers having a basis weight generally in the range of from about 25 to 300 gsm and including a meltblown web having incorporated therein a staple fiber mixture including synthetic and cotton fibers. The combination provides highly improved wiping properties as well as strength and absorbency for many industrial applications requiring wiping of oily and/or aqueous materials. The wipers may be formed by a conventional meltblowing process involving extrusion of a thermoplastic polymer as filaments into airstreams which draw and attenuate the filaments into fine fibers having an average diameter of up to about 10 microns. The staple fiber mixture of synthetic and cotton fibers may be added to the airstream, and the turbulence produced where the airstreams meet results in uniform integration of the staple fiber mixture into the meltblown web. The matrix may contain up to 90% by weight of the synthetic and cotton fiber blend, which, itself, may contain up to about 90% by weight of the synthetic fibers. The meltblown web may be formed from a wide variety of thermoplastic polymers including polyolefins, polyamides, polyesters, and the like. The synthetic fiber component of the staple fiber mixture may also be formed from such synthetic thermoplastic materials as well as others including rayon, polyacetate, and the like. Wipers produced in accordance with the invention have particularly improved oil absorption rate and clean wiping properties as demonstrated by residual testing and capillary suction curves. 1. In particularly preferred embodiments, the staple component has a denier in the range of up to 6 denier for even further improved wiping properties. The matrix is preferably bonded by a patterned application of heat and pressure or sonic energy providing for a percent surface area of bonding in the range of from about 5 to 30 with individual bonds in the range of from about 20 to to 200 bonds/in2 or line patterns either generally in a single direction or intersecting in the range of 2 to 15 lines per inch. 2.
