Abstract: A soft uncreped throughdried tissue product is disclosed having uniformly distributed surface deposits of a chemical composition which imparts a benefit to the user, such as a reduction in skin irritation during use. Particularly suitable compositions are those which have a melting point of from about 30.degree. C. to about 70.degree. C. and which are applied to the outer surfaces of the tissue product in melted form, preferably by rotogravure printing. A suitable composition contains an oil, a wax, and preferably a fatty alcohol.

Abstract: A method of producing self-texturing filaments that exhibit a desirable tendency to coil rather than to bend sharply or zig zag. The method includes directing a quenching fluid at extruded hollow filaments of a liquid polymer predominantly from one side of the hollow filaments to thereby produce hollow filaments with different orientations on each side. Thereafter the temperature of the hollow filaments is raised to a temperature sufficient for the filaments to relax, but less than the temperature at which the filaments would shrink. When the relaxed filaments are cut into staple lengths, they tend to assume a form that provides a favorable degree of mechanical entanglement that is useful in forming resilient solid structures.

Abstract: A diaper containing a liquid pervious topsheet coated with a lotion composition is disclosed. The lotion composition reduces the adherence of BM to the skin of the wearer, thereby improving the ease of BM clean up, and improves skin softness. The lotion composition comprises a solid polyol polyester and an emollient to improve the lubricity of the solid polyol polyester. The polyol polyester(s) and emollient remains at or near the skin surface, providing the desired BM cleaning or therapeutic benefits.

Abstract: A pad is provided for use on a machine for the polishing of silicon wafers which allows the use of optical detection of the wafer surface condition as the wafer is being polished. This accomplished by constructing the entire pad or a portion thereof out of a solid uniform polymer sheet with no intrinsic ability to absorb or transport slurry particles and which is transparent to the light beam being used to detect the wafer surface condition by optical methods. Polymers which are transparent to light having a wavelength within the range of 190 to 3500 nanometers are suitable for the construction of these pads.

Abstract: A tear resistant film comprises more than five layers situated one on the other in a parallel array. The layers are individually selected from a stiff polyester or copolyester, a ductile polymeric material, and optionally, an intermediate material. The stiff polyester or copolyester is oriented in at least one direction. Tear resistance may be measured in a Graves area test and reflects the ability of the film to absorb energy. The films of the invention are useful in many articles including security control laminates for glazing members.

Abstract: The present invention provides a nonwoven fabric laminate comprising a thermally-bonded multiconstituent fiber nonwoven web. The multiconstituent fiber is composed of a highly dispersed blend of at least two different thermoplastic polymers which are present as a dominant continuous phase and at least one noncontinuous phase dispersed therein. The noncontinuous phase exists as an elongated fibrillar polymer domain oriented generally in the direction of the fiber axis. The polymer of the noncontinuous phase has a melting temperature below that of said continuous phase, and the lower melting noncontinuous phase comprises from about 2.5 to about 20 percent by weight of the fiber. The fabric laminate also comprises at least one other web bonded to the multiconstituent fibers of the thermally bonded nonwoven web and a multiplicity of thermal bonds formed from the polymer of said multiconstituent fibers and bonding the multiconstituent fibers of said thermally bonded web to said at least one other web.

Abstract: An improved thermally insulating batt particularly designed for use as filling material for winter apparel, quilts, sleeping bags and the like, is produced by first preparing carded webs consisting of natural or synthetic fibers, plying several webs to form a batt, and then subjecting this batt to a subsequent resin treatment, on at least one face thereof, by using specific cross-linked glues. The resin treated batt is then calendered, under controlled temperature and pressure conditions, so as to obtain, on its surface, a soft, resilient and heat-sensitive film and, in the interior, an air chamber so as to provide a low thermal exchange coefficient and a proper control of the body temperature.

Abstract: A method of producing easily densified high bulk fibers that have adhered particulates. The high bulk fibers have hydrogen bonding or coordinate covalent bonding functionalities, and a binder is applied to the fibers to bind the particles to the fibers. The binder has a functional group that forms a hydrogen bond or a coordinate covalent bond with the particles, and a functional group that forms a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers are adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder is in turn adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

Abstract: The textile spacer material is a material for replacing foamed substances; it consists of two knitted or woven covering layers that are connected by a pile thread structure. The pile thread structure produces the compressibility known from flexible foams and the large air fraction. The elasticity can be determined by the length and density of the pile threads and the material used. When recyclable materials are used, an environmentally compatible foam substitute can be obtained. Moreover, the textile spacer material can also assume chemical or physical properties through the use of treated starting material or a treatment during or after production and thus be used as a filter or catalyst material, for example.

The method includes the steps of heating at least one nonwoven web containing meltblown non-elastic thermoplastic polymer fibers to a temperature at which the peak total energy absorbed by the nonwoven web of meltblown fibers is at least about 250 percent greater than the amount absorbed by the nonwoven web of meltblown fibers at room temperature; applying a tensioning force to neck the heated nonwoven web; and cooling the necked nonwoven web so that the nonwoven web has at least the same hydrostatic head and/or particulate barrier properties as the nonwoven web before necking. Also disclosed is a stretchable barrier fabric composed of a nonwoven web of meltblown non-elastomeric thermoplastic polymer fibers, the nonwoven web being heat treated so that it is adapted to stretch at least about 10 percent more than an identical untreated nonwoven web of meltblown non-elastomeric thermoplastic polymer fibers.
