摘要： A filter medium having high stiffness is provided. The filter is a nonwoven web of conjugate fibers which has a Frazier permeability above 200 CFM, an NaCl efficiency above 75 percent, a Gurley Stiffness above 700 mg, and a SEP value of above 80. The conjugate fibers may be polyolefin, more particularly polypropylene and polyethylene in a side-by-side configuration. The medium may be made into a filter by conventional means such as pleating. Such filters are useful in HVAC systems and transportation cabin air filtration.

摘要： The invention relates to a means (150) for determining the soiling of a workpiece (108). The means contains a device (155) for capturing dirt particles contained in a characteristic liquid volume on a filter diaphragm (158), said dirt particles being introduced into a liquid when the workpiece (108) is subjected to the action of the liquid. In the means (150) there is a system (169) for analysing the dirt particle load, captured by the filter diaphragm (158), from the liquid. The system (169) for analysing has an analysing means (170) connected to a computer unit (202), wherein the flat filter diaphragm (158) is in the form of a band and can be moved at least sectionally relative to the analysing means (170) by means of a transport device (160). The computer unit (202) connected to the analysing means (170) is used to determine dirt particle measured value (M) in the form of the type and/or number and/or size and/or size distribution of dirt particles (166) accumulated on the section (174) of the filter diaphragm (158).

摘要： Disclosed are a blood filter which exhibits excellent leukocyte elimination performance as well as significantly improved blood throughput per unit time and erythrocyte recovery rate and a method of manufacturing the same. The blood filter of the present invention includes a pre-treatment filter which is a laminate of first non-woven fabrics having a mean fiber diameter of 5 to 30 µm and a mean pore size of 10 to 30 µm, and a main filter which is a laminate of second non-woven fabrics having a mean fiber diameter of 1 to 5 µm, a mean pore size of 5 to 10 µm and a mean pore size distribution rate of 30% or more. A filling density of the pre-treatment filter and a filling density of the main filter, with respect to a target blood throughput of the blood filter, are 0.1 g/100 ml to 1 g/100 ml and 1 g/100 ml to 3 g/100 ml, respectively.

摘要： By, according to the invention, manufacturing a filter cloth (5, 6) especially to be used in filtering of gas flows, which filter is manufactured in a rolling mill where the individual layers are laminated with a membrane layer (1), to which by the use of a binder (2), such as thermoplastic sheeting, is glued a filter layer (4) with at least one metal layer (3, 13). Hereby is achieved a robust laminate (5, 6), which is, in addition, easy to manufacture in a rolling mill with heated rollers for melting of the binder (2).

摘要： Fibrous structures containing immobilized particulate matter and processes for making them are disclosed. These structures may be used for filters and for fabrics including chemical defense garments and others. The fibrous structures have webs containing composite fibers having a lower melting component and a higher melting component. The particles are distributed into the interior of the web and fused to the low melting component of the individual fibers without substantially reducing the available surface area of the particle. A fibrous structure of a composite staple having a nylon sheath and a polyester core, with activated carbon particles bonded to the sheath is specifically disclosed. The processes for producing such a fibrous structure include carding a web of staple fibers and distributing particulate matter therein, air laying a web of staple fibers and distributing particulate matter therein, spin bonding a web of continuous filaments and distributing particulate matter therein, and wet forming a web of staple fibers and particulate from a suspension thereof between two wet formed layers of staple fibers. One or more additional layers of nonwoven, woven, or knit webs or fabrics may be bonded thereto.

摘要： Fibrous structures containing immobilized particulate matter and processes for making them are disclosed. These structures may be used for filters and for fabrics including chemical defense garments and others. The fibrous structures have webs containing composite fibers having a lower melting component and a higher melting component. The particles are distributed into the interior of the web and fused to the low melting component of the individual fibers without substantially reducing the available surface area of the particle. A fibrous structure of a composite staple having a nylon sheath and a polyester core, with activated carbon particles bonded to the sheath is specifically disclosed. The processes for producing such a fibrous structure include carding a web of staple fibers and distributing particulate matter therein, air laying a web of staple fibers and distributing particulate matter therein, spin bonding a web of continuous filaments and distributing particulate matter therein, and wet forming a web of staple fibers and particulate from a suspension thereof between two wet formed layers of staple fibers. One or more additional layers of nonwoven, woven, or knit webs or fabrics may be bonded thereto.
