摘要： Stitchbonded composite wiper with improved softness, bulk, hand conformity, absorbency and strength performance characteristics having a construction comprised of a middle layer of cellulose natural fibers and outer layers of either continuous filament thermoplastic fibers, meltblown thermoplastic microfibers or rayon fibers. The layers are laminated into a composite by stitch-bonding using stitching yarn of either polyester, cotton, rayon, nylon or a blend. The preferred construction of an inner layer of two ply lightweight cellulose natural fibers with relatively lightweight continuous filament thermoplastic fiber layers, on both outer sides of the cellulose fiber layer, bonded by stitching with a medium to heavy textile yarn in a prescribed stitch pattern provides a composite wiper having layer bond strength and hand feel of a desired textile nature along with improved wipe performance characteristics. This stitchbonded composite wiper while economically disposable is reusable and effective for multiple applications, particularly those applications of a heavy duty nature wherein wiping is traditionally performed using textile wiping materials or heavy weight nonwovens.
