    摘要: A wet wipe which includes a pattern bonded polypropylene nonwoven web adapted to provide a sustained controlled release to a surface of an aqueous alcoholic composition contained within the nonwoven web. The nonwoven web has a basis weight of from about 17 to about 100 grams per square meter and includes polypropylene meltblown fibers having diameters in a range of from about 0.01 to about 50 micrometers. The aqueous alcoholic composition contained within the polypropylene nonwoven web is present in a range of from about 300 to about 600 weight percent, based on a dry weight of the nonwoven web of 34 grams per square meter. The wet wipe provides a first release of the aqueous alcoholic composition in a range of from about 40 to about 70 weight percent, a second release in a range of from about 10 to about 25 weight percent, and a third release in a range of from about 5 to about 18 weight percent, of the composition originally present in the nonwoven web. The total amount of the aqueous alcoholic composition remaining in the nonwoven web after three releases is no more than about 25 weight percent, based on the amount of the composition originally present. Also provided is a method of applying a sustained controlled release of an aqueous alcoholic composition to a surface.

    摘要: A biodegradable, cellulose-based collecting sheet that can be used in either a wet state or a dry state. The collecting sheet may be a double recreped cellulose substrate reinforced with a binder, such as a latex binder. Alternatively, or in addition to the binder, the collecting sheet may be coated with a dielectric material and electret treated to establish a charge on the dielectric material. Additionally, the collecting sheet may be embossed to provide more interstices and greater surface area to enhance the pick-up ability of the collecting sheet. The invention further includes a method of forming such a collecting sheet.

    摘要: An apparatus and a method for ultrasonically producing a spray of liquid. 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 to produce a spray of liquid. 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 to produce a spray of liquid.

    摘要: An adsorbent filter for removing caffeine from liquids. The filter is composed of a liquid permeable, electret-treated matrix of fibrous material having individual exposed surfaces; and a relatively uniform distribution of adsorbent zeolite particulate material attached to individual exposed surfaces of the electret-treated fibrous material by substantially non-transient bonding, so that passage of a liquid having a caffeine concentration ranging from about 20 to about 100 mg per 100 mL of liquid through the matrix for a contact time of less than about 2 minutes results in at least a 40 percent reduction in the caffeine concentration of the liquid. The matrix of fibrous material may be selected from woven fabrics, knit fabrics and nonwoven fabrics. Generally speaking, the filter can be adapted to provide at least a 40 percent reduction in the caffeine concentration for about 1 cup to about 40 cups of a liquid.

    摘要: An apparatus and method for controlling an ultrasonic transducer preferably including a signal generator circuit, a signal sensing circuit, a modulator circuit, and a bias circuit. The signal generator circuit provides a pulsed drive signal to the ultrasonic transducer. The signal sensing circuit senses the voltage and current of the drive signal. The modulator circuit provides a frequency control signal and an energy control signal to the signal generator circuit corresponding to a detected phase difference between the sensed voltage and the sensed current of the drive signal. The frequency control signal and energy control signal operate to adjust the frequency and energy level, respectively, of the drive signal.Within the transducer, a movable element in contact with a liquid is preferably positioned corresponding to the level of a dc bias signal provided by the bias circuit. By adjusting the level of the dc bias signal, the flow rate of the liquid is adjusted. By applying the drive signal to the transducer, the viscosity of the liquid is adjusted which establishes a second flow rate of the liquid. When the frequency and energy level of the drive signal are changed, a third flow rate of the liquid is established.

    摘要: A fibrous web having a length, a width and a thickness, with at least about 50 percent of the fibers aligned in a direction generally perpendicular to the length and width of the web. The web defines a plurality of spaced-apart gaps, each having a top and a bottom, and each of the gaps extends from one surface of the web at least about 50 percent through the thickness of the web. The density of a portion of the web defining the bottom of the gap is greater than the density of a portion of the web defining the top of the gap. The portion of the web which defines the top of the gap may be composed substantially of terminal ends of the fibers. In addition, the portion of the web which defines the bottom of the gap may be composed substantially of continuous fibers. The fibrous web may be a meltblown nonwoven web or a neck-stretched, meltblown nonwoven web. The fibrous web may be employed as a component of such absorbent products as diapers; incontinent care products; and feminine care products, such as sanitary napkins and tampons; filter elements; and the like. The web provides improved distribution of liquid in the direction of fiber alignment.
