摘要： Disclosed is a hydrodisintegratable material which, when injection molded into an object, acquires and maintains the desired shape without becoming brittle. Additionally, in the presence of water, the molded object has the ability to rapidly disintegrate and disperse when subjected to standardized agitation testing. The moldable material typically includes: (1) from about 7.5 to about 85 weight percent of at least one water dispersible polymer; (2) from about 7.5 to about 85 weight percent of at least one xerogellant; and (3) at least one volatile material, where the weight percentage of all volatile materials present in the material is within a range which is defined, at its lower end, by the weight percentage of all volatile materials which assures that the material will not become brittle upon being molded and is defined, at its upper end, by the highest weight percentage of all volatile materials which results in the material satisfactorily conforming to the desired physical configuration upon being molded. A process for forming such an object is disclosed.

摘要： Disclosed are a number of processes for forming a liquid-impermeable sheet having a fibrous cloth-like surface. In one embodiment the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces; and subjecting the sheet to pressure and a z-gradient temperature differential sufficient to melt the fibers of the first surface and form the melt into a liquid impermeable skin without significantly altering the fibers of the second surface. In another embodiment, the process includes the steps of: (1) forming a sheet having first and second fibrous surfaces wherein, upon the sheet being subjected to a sufficient temperature, the fibers forming the first fibrous surface are adapted to substantially completely melt prior to the fibers forming the second fibrous surface significantly melting; and (2) subjecting the sheet to a sufficient pressure and temperature to melt the fibers of the first surface and form the melt into a liquid impermeable skin without significantly altering the fibers of the second surface. In some embodiments the liquid impermeable skin is subsequently apertured to make the sheet breathable. Products formed by these processes are also disclosed.

摘要： The present invention is directed toward a fibrous web having improved strength characteristics which, in the presence of water, rapidly disintegrates when subjected to standardized agitation testing. The web includes a plurality of fibers joined together by a binder. The binder makes up from about 0.20 to about 15 percent of the dry weight of the web. The binder is formed from a blend of from about 10 to about 40 weight percent of a water dispersible, high molecular weight amorphous polyester having one or more ionic substituents attached thereto; from about 10 to about 40 weight percent of an elastomeric latex emulsion; from about 20 to about 40 weight percent of a xerogellant; and from about 5 to about 20 weight percent of a plasticizing agent. The fibrous web is useful in the formation of disposable diapers and feminine care products which may be flushed down the toilet.

The method includes the steps of (1) placing the thin sheet material on a pattern anvil having a pattern of raised areas wherein the height of the raised areas is generally less than the thickness of the sheet material; (2) conveying the sheet material, while placed on the pattern anvil, through an area where a fluid is applied to the sheet material; and (3) subjecting the sheet material to a sufficient amount of ultrasonic vibrations in the area where the fluid is applied to the sheet material to area thin the sheet material in a pattern generally the same as the pattern of raised areas on the pattern anvil. In some embodiments, the thinned areas may be micro areas.

摘要： Particle-laden meltblown material, methods for forming such material, composite laminate fabrics using such material as a layer of the laminate, and uses of such material and/or laminate thereof are disclosed. The particle-laden meltblown material is a coform of the particles and meltblown fibers, consolidated into a meltblown material. The meltblown fibers are made of polymeric materials such that the fibers are tacky after extrusion from the meltblowing die and prior to consolidation as meltblown material; active particles (such as active carbon) are incorporated in the stream of meltblown fibers, as the fibers pass from the die to the consolidation surface, at a location where the fibers are tacky, so that the particles adhere to the surface of the fibers. The polymeric materials forming the meltblown fibers can be elastomeric materials, and/or blends of polymers. The formed meltblown material can be used as a layer of a laminate, with other layers of the laminate providing abrasion resistance and mechanical strength. The meltblown material, and/or laminate including the meltblown material, can be used for gas/vapor filtering and/or adsorbing, and specifically can be used for disposable vacuum cleaner bags and the like.

摘要： There is provided a disposable personal article with a polymer having a glass transition temperature ranging between 25 and 45° C. The polymer is tacky over the temperature range, which is approximately that of the body, and results in better sealing of the personal care product to the wearer and so a decrease in the amount of bodily exudates that escape to soil the clothing of a wearer. The preferred polymer has a main chain, lateral perfluoroalkyl groups and lateral alkyl groups.

摘要： An ultrasonic apparatus and a method for injecting a pressurized liquid fuel by applying ultrasonic energy to a portion of the pressurized liquid fuel. The apparatus includes a die housing which defines a chamber adapted to receive a pressurized liquid and a means for applying ultrasonic energy to a portion of the pressurized liquid. The die housing further includes an inlet adapted to supply the chamber with the pressurized liquid, and an exit orifice defined by the walls of a die tip. The exit orifice is adapted to receive the pressurized liquid from the chamber and pass the liquid out of the die housing. When the means for applying ultrasonic energy is excited, it applies ultrasonic energy to the pressurized liquid without applying ultrasonic energy to the die tip. The method involves supplying a pressurized liquid to the foregoing apparatus, applying ultrasonic energy to the pressurized liquid but not the die tip while the exit orifice receives pressurized liquid from the chamber, and passing the pressurized liquid out of the exit orifice in the die tip.
