    摘要： A technology for measuring an air permeability which can avoid, by using pure water in place of oil as a sealing liquid, adverse effects by oil mist and can accurately measure an air permeability by identifying variations in vapor concentration to be caused by using water. A device for measuring an air permeability installed in a constant temperature/humidity room,wherein an air chamber (22) is formed inside an inner tube (2) with the inner tubu fitted in an outer tube (1) storing a sealing liquid, a sample clamping unit (5) is provided between an air passage (3) extending from the air chamber through the bottom of the outer tube and an exhaust passage (42) facing the air passage, pure water (W) is used as the sealing liquid, and a temperature/humidity measuring unit (6) and an air supply port (7) opened/closed by a solenoid valve (71) are provided in the vicinity of the sample clamping unit in the air passage.

    摘要： Disclosed is an improved structure that includes a nonwoven web including a viscoelastant treatment. The treated web, when contacted by a viscoelastic fluid such as menses alters the viscoelastic properties of the fluid and enhances its wicking and distribution throughout the absorbent structure. A desirable viscoelastant is an alkyl polyglycoside, particularly those having 8 to 10 carbon atoms in the alkyl chain. When applied so as to provide an amount of about 0.1 % to about 5.0 % solids add-on based on the weight of the dry nonwoven web, rapid fluid wicking and distribution may be obtained. Other viscoelastants are disclosed. Advantageously the treatment may be applied as a high solids composition using conventional application means such as spray coaters and the like or as an internal additive. The absorbent structure finds particular utility as a distribution layer component of a sanitary napkin for absorbing menses as well as other blood handling products such as surgical drapes, for example.

    摘要： Gas permeability of very low permeability subterranean formations, and the gas permeability reducing effects of injecting one or more treatment fluids thereinto, are measured by injecting a gas into a core sample of the formation at a selected substantially constant pressure, and continuing the injection for a long period of time to ensure steady state flow conditions. The temperature of the gas as it flows through the core sample and the flow rate of the gas exiting the core sample are measured, and the native state gas permeability of the core sample is calculated therefrom. One or more treatment fluids can be injected into the core sample after the native state permeability is determined. Thereafter, the gas permeability can again be determined and compared to the native state permeability.
