Estimating the term…
A nonwoven disposable towel, having particular utility as a surgical towel, comprising a five-ply structure and method of making it. The outermost plies of the towel are tissue. To each of these tissue plies there is adhered an intermediate ply constituting a medium density, thermoplastic, long fibered, nonwoven material. These tissue-intermediate ply assemblies comprise primary laminates accounting for four plies of the towel. Between these primary laminates there is located a fifth or center ply constituting a low density, melt blown, long fibered, nonwoven material. The entire structure is heat sealed about its periphery and additional spot heat bonds may be employed to minimize slippage between the center ply and the two primary laminates. The two primary laminates may be embossed prior to assembly of the towel.
A disposable, sterilizable, surgical towel having a five-ply construction comprising a center ply of wettable microfibrous melt-blown fibers having a basis weight of from about 20 to about 60 grams per square meter and two identical primary laminates to each side of said center ply and each comprising an intermediate ply of wettable thermoplastic fibers having a basis weight of from about 10 to about 30 grams per square meter adhesively secured to a tissue ply having a basis weight of from about 10 to about 30 grams per square meter, said tissue plies comprising the outermost plies of said towel, said center ply and said primary laminates being bonded together about the periphery of said towel.
A disposable towel having a five-ply construction comprising a low density, soft, bulky, bendable, wettable, highly absorbent, nonwoven center ply and two identical primary laminates to each side of said center ply, each of said primary laminates comprising an inner ply and an outer ply adhesively adheared together, said inner ply comprising a medium density, soft, bendable, wettable, nonwoven ply, said outer ply comprising an abrasion resistant, low linting, soft, bendable, tissue ply, said primary laminates being characterized by fast strike through, said tissue plies comprising the outermost plies of said towel, said center ply and said primary laminates being bonded together about the periphery of said towel.
