摘要： A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than −7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of −7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than −7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles.

摘要： A nonwoven fabric comprises continuous polymer filaments of 0.5 to 3 denier that have been hydroentangled in a complex matrix for interconnecting filament loops, and that is otherwise substantially free of knotting, or of otherwise wrapping about one another. A process for making a nonwoven fabric comprises continuously extruding polymer filaments of 0.5 to 3 denier onto a moving support, pre-entangling the filaments with water jets, and entangling the filaments with a second set of water jets on a three-dimensional image transfer device. An apparatus for making a nonwoven fabric comprises means for continuously extruding substantially endless polymer filaments of 0.5 to 3 denier onto a moving support to form an unbonded web, a pre-entangling station for entangling the web with a plurality of water jets, and a plurality of water jets for final entanglement of the filament web on a three-dimensional image transfer device. In another aspect of the present invention, plural precursor webs, each comprising polymeric filaments, can be employed to form a laminated nonwoven fabric.

摘要： A nonwoven fabric includes a cohesively integrated web of hydrodynamically entangled short-staple or nullwaste cottonnull fibers. A batt of waste cotton fibers is hydrodynamically needled by high-pressure streams of water. The hydrodynamic energy of the streams causes the fibers to cohere and to become mutually entangled, which in turn results in a fabric of sufficient strength to be used for, among other things, a bag for a bulk material and particularly a bag or cover for a cotton bale.

摘要： Staple fibers made from crimped, in particular compression crimped, multicomponent filaments of the matrix/segment type, the cross section of which shows, in addition to the matrix, at least 6 peripheral wedge-shaped or lenticular segments, not completely covered by the matrix, are processed into a web, which is then mechanically bonded, preferably by needling. Subsequently, the fabric is subjected to a shrinkage process, by which its density is increased by more than 30%, the multicomponent fibers being completely or partly split up into their components. The difference in shrinkage between the components should be at least 10%. The liquids used for the shrinkage treatment are in particular organic liquids, such as methylene chloride, as well as other liquids producing a difference in shrinkage of at least 20%. The fabric is then impregnated with a solution of polyurethane on the basis of polyglycols, specifically polytetramethylene glycol, diisocyanates and low-moleclar glycols as chain lengtheners, the jelling temperature of the solution being higher than the room temperature and higher than the temperature of the coagulation bath; the polyurethane is coagulated by cooling and/or treatment with a coagulation bath containing a non-solvent for polyurethane; then the fabric is washed, dried and ground on one or both sides. The suede-like product obtained combines great suppleness with high strength. It is an excellent material for making garments, such as coats, jackets or skirts, offering high wear comfort as well as high breathability.
