    摘要： In a filter bed (11) for the solid/fluid separation of media which contain substances that attack or dissolve cellulose, for example cellulase-containing enzymes, a matrix comprising a fibrous material structure of polyolefin fibrid particles (12) which are matted and anchored in one another and which can additionally contain up to 20% by weight of narrower fibrid polyolefin fibres and/or polyolefin fibres that have a fibre length of up to 5 mm. and have just started to fibrillate, in order to strengthen the sheet formation of the matrix. The actual filter-active particles, in particular kieselguhr particles and/or perlite particles having grain sizes of 5 to 100 um., are embedded in the cellulose-free fiber matrix.

    摘要： The disclosure related in part to a novel and highly superior high bulk pulp formed of lignin-containing fibers, and to process conditions for manufacture of the pulp. The process involves selection of a lignin-containing fiber source, having a lignin content of at least about 10%, and thermomechanically pulping the fiber source under temperature/pressure conditions of 300.degree. F.-350.degree. F./50 psig-120 psig and a refiner energy utilization of about 8-35 HPT/ADT, using a double disc, counter rotating disc refiner. The thermomechanically produced fibers are characterized by a high degree of stiffness, and an extremely smooth surface, free of fine fibril formation and thus substantially non-self-bonding. The new pulp has a wide variety of specialty uses which are attractive in terms of both economics and technical performance, because of the exceptionally high bulk and other distinctive characteristics of the fiber.Novel and highly superior filter media, formed using the new pulp which filter media are particularly useful in the filtration of lube oil, fuel and air. The filter media are formed by a random lay-up of the lignin-containing fibers, typically with selected other pulp fibers having technical characteristics suitable for filter media utilization. Suitable lignin-containing fiber, produced under conditions of the invention, may be substituted with minimum effort for conventional technical fibers utilized in furnishes intended for filter media production. The new filter media are characterized by exceptionally high bulk, void volume and dust capacity-high critical characteristics of filter media, and provide equal or superior product performance at significant reductions in production cost and/or exceptional improvement in filtration performance at equivalent production cost.

    摘要： A glass fiber filter mat possessing excellent wet strength which is in the form of a non-woven matrix of glass micro-fibers including polymer micro-bits derived, for example, from a non-brittle expanded, thermoplastic styrene polymer or a flexible foamed polyurethane, the micro-bits being substantially free of intact cells. Also included in the filter mat is a cobeat or intimate blend of cellulose fibers and the polymer micro-bits, which may additionally contain polyester fibers, as well as a combination of binders, viz., polyvinyl alcohol and a melamineformaldehyde resin.
