Abstract: A method for making a fibrous web and the wiper (71) made thereby which exhibits improved dry, wet and solvent tensile strengths as well as superior resistance to wet collapse. The web is formed from a furnish of lignocellulosic fibers and bi-component fibers, the web having a basis weight in the range of about 20 lbs per ream to about 60 lbs per ream. Bonding material (75) is applied in at least one pattern to each surface of the web, and the web is creped at least twice from a creping surface. Lignocellulosic fibers make up from about 50 % to about 94 % by weight of the web. Bi-component fibers of polyester and polyethylene make up from about 6 % to about 50 % by weight of said fibrous web. The fibrous web has an undulating disposition due to creping and has first and second strong, abrasion resistant, laminate-like surface regions interconnected by an absorbent central de-densified core region containing tack-bonded bi-component fibers.
