Abstract: Uncreped throughdried basesheets can be made with the caliper of the basesheet being independent of the basis weight of the basesheet. Multi-ply wipers and towels produced by plying together two or more of such basesheets having a relatively low basis weight can provide products with improved caliper and absorbency for a given strength level and the amount of fiber used.

Abstract: This invention provides a densified previously expanded PTFE article having remnants of a fibril and node structure and a process for producing the article. A PTFE shape is compressed through the application of heat and pressure while the shape itself is under a vacuum, thus forming the densified ePTFE article. The densified PTFE article exhibits increased flexural strength.A diaphragm containing the densified ePTFE article as one layer is also disclosed.

Abstract: A method of cleaning a metal surface includes covering the portion of the metal surface with a cleaning tape. The cleaning tape is chromium in combination with a fluoride ion source bound together by fibrillated polytetrafluoroethylene. This is applied to the portion of the area to be cleaned and is subject to heat treatment at about 1800.degree. F. and a reducing atmosphere of preferably hydrogen. This effectively cleans only the area covered by the tape. Further, the tape and binder format acts to force fluoride ions into the cracks on the surface providing a significantly improved cleaning operation.

Abstract: A thermoplastic resin defines a core of a thermoformable thermoplastic composite material. The core is sufficiently thick to provide for a shaping of the composite material at an elevated temperature to any desired configuration. First and second layers of fabric material are disposed on opposite sides of the core. The fabric material may be formed of glass, carbon or aramid and may be formed from woven fibers, unidirectional or chopped fibers or random strand mats. The fabric layers have a thickness sufficient to impart strength and rigidity to the fabric material. Layers of a thermoplastic thermoformable resin material may be disposed on the layers of the fabric material. The thermoplastic layers impregnate the fabric layers, bond the fabric layers to the core and provide a smooth external surface to the composite material.

Abstract: The invention is to a non-woven fabric sheet for a storage battery separator. The sheet has an excellent property of holding electrolyte by using conjugate fibers having a specific sectional form. The sheet comprises an ethylene copolymer having a specific structure which can introduce a desirable amount of sulfo groups efficiently under mild reaction conditions. Conjugate fibers having a split sectional form include a first component and a second component having a radial arrangement. The conjugate fibers are obtained by forming an ethylene based random copolymer containing a unit represented by a formula --CH.sub.2 CH(COOH)--, with polypropylene. Subsequently, a non-woven fabric sheet of a thermally bonding type is obtained by mixing the conjugate fibers with polypropoylene fibers. Subsequently, a non-woven fabric sheet for a storage battery separator is obtained by sulfonating the non-woven fabric sheet using gas such as SO.sub.3 to form a unit of the formula --CH.sub.2 C(SO.sub.3 H)(COOH)--.

Abstract: Disclosed is an abrasion resistant fibrous nonwoven structure composed of (1) a matrix of meltblown fibers having a first exterior surface, a second exterior surface, and an interior portion; and (2) at least one other fibrous material integrated into the meltblown fiber matrix so that the concentration of meltblown fibers adjacent each exterior surface of the nonwoven structure is at least about 60 percent, by weight, and the concentration of meltblown fibers in the interior portion is less than about 40 percent, by weight. This fibrous nonwoven structure provides useful strength and low-lint characteristics as well as an abrasion resistance that is at least about 25 percent greater than that of homogenous mixture of the same components. The fibrous nonwoven structure of the present invention may be used as a moist wipe.

Abstract: The dimension-stable impregnated polyester tire cord is at least 95% by weight polyethylene terephthalate and has an intrinsic viscosity of 0.70 dl/g to 0.89 dl/g for undrawn cord, a fineness of at least 1100 x 2 dtex, a dimension stability coefficient of at least 30'000 cN.sup.2 /tex.sup.2, a thermal shrinkage of about 0.8 percent measured at a temperature of 160.degree. C. with 0.1 cN/tex pre-stress and a permanent lengthening of less than 1.5 percent at a tire pressure of 2 bar and a temperature of 100.degree. C., so as to reduce shrinkage during vulcanization and in tires heated in operation and so as to provide a quieter running tire. The fatigue resistance of this polyester tire cord suffers a drop in tensile strength of less than 20 percent measured at 10.8 MC with 6 percent strain and 6 percent compression so that tires made from the polyester cord have a greater durability and increased life.

Abstract: Bulky split fibers having bond strength are produced by preparing a composite synthetic resin film of three layer structure having a polypropylene layer formed of a polypropylene/polyethylene blend and a polyethylene layer on either surface of the polypropylene layer, slitting and stretching the composite film to thereby form stretched tapes, and causing splitting of the stretched tapes for fibrillation. An integral article is prepared from the resultant split fibers by mixing them alone or with plant fibers and then heating at a temperature between the melting points of polyethylene and polypropylene, thereby integrating together the split fibers with each other or with the plant fibers.
