摘要： The invention relates to non-woven fabrics comprising threads not produced with the spun-bonding method, for example made of non-melt spinnable thread-forming materials. The use of these fibers, optionally in combination with filaments produced using the spun-bonding method, allows the production of novel non-woven fabrics with novel property combinations. The production can be carried on conventional spun-bonding equipment, wherein part of the extruding devices are used as conveyors for the threads not produced with the spun-bonding method.

摘要： Method and device for manufacturing a flat textile structure in which two melts of at least two polymer materials are changed to the form of fibers with the aid of a spinning device and in which fibers are then combined and then solidified. The spinning device consists of a spinning rotor and the polymer materials employed have an charge difference of at least ten unit charges. The two materials are first melted separately from one another. Each melt, by means of a distributor device, is then fed to a group of outlet openings of a spinning rotor unmixed. The fibers emerging from the outlet openings are then stretched and combined to form a common flat structure with the flat structure then being charged triboelectrically by an aftertreatment.

摘要： Porous bodies, particularly membranes in the form of hollow filaments, are produced by heating a polymer above the upper critical temperature T.sub.c in a mixture of two compounds A and B, liquid and miscible at the dissolving temperature, whereby the employed mixture (polymer, compounds A and B) in liquid aggregate state displays a miscibility gap, the compound A is a solvent for the polymer and the compound B, which preferably is a non-solvent or a swelling agent for the polymer, raises the phase separation temperature of a solution composed of the polymer and compound A. After the dissociation, the components A and/or B if necessary are extracted. Through use of non-toxic substances such as e.g. edible oil as compound A and castor oil as compound B, bodies are obtained which are non-toxic and unobjectionable for use in medical areas and in the foods industry, among others.

摘要： A new water-swellable composition of a gelling agent based on hydrolyzed homo- or copolymers of acrylonitrile and of an inert metal oxide was synthesized. In the process, 1 to 22% of the nitrile groups were saponified to amide groups and 99 to 78% to alkali-metal salts. The obtained composition had a spongy structure and was characterized by high values with regard to both swelling capacity and swelling rate. Therefore it is particularly suitable for diaper manufacture and for agricultural use.
