摘要： Melt blown or spun bond nonwoven webs are formed by flowing fiber-forming material through a die cavity having a substantially uniform residence time and then through a plurality of orifices to form filaments, using air or other fluid to attenuate the filaments into fibers and collecting the attenuated fibers as a nonwoven web. Each die orifice receives a fiber-forming material stream having a similar thermal history. The physical or chemical properties of the nonwoven web fibers such as their average molecular weight and polydispersity can be made more uniform. Wide nonwoven webs can be formed by arranging a plurality of such die cavities in a side-by-side relationship. Thicker or multilayered nonwoven webs can be formed by arranging a plurality of such die cavities atop one another.

摘要： Disclosed is a process for preparing a fibrous web. The fibrous web includes a microencapsulated material, such as a microencapsulated phase change material, adhered to the web. Preferably, the web is prepared in a melt-blowing or spun-bonding process. In the melt-blowing process, cooling water containing the microcapsules is used to cool melt blown fibers prior to collection on a collector. In the spun-bonding process, microcapsules are applied in liquid suspension or in dry form to a heated web, for instance, after the web has been calendared. The fibrous webs thus prepared have numerous uses, and are particularly suited to the manufacture of clothing.

摘要： A melt-extrudable polymeric strand with enhanced tensile strength formed by extruding a melt-extrudable polymer while subjecting the a portion of the polymer to ultrasonic energy. The melt-extrudable polymeric strand has a tenacity which is from about 1.5 to about 3 times the tenacity of an otherwise identical strand not made by applying ultrasonic energy to a portion of the melt-extrudable polymer while the melt-extrudable polymer is extruded. Desirably, the strand has a tenacity within a range from about 0.3 to about 0.9 g/denier. In a method for making such a strand, a molten melt-extrudable polymer is extruded through a die assembly, ultrasonic energy is applied to a portion of the melt-extrudable polymer within the chamber and without applying ultrasonic energy to the die tip, while an extrusion exit orifice receives melt-extrudable polymer from an extrusion chamber, and the extruded polymer is attenuated to form a strand. The extrusion of the melt-extrudable polymer and the excitation of the means for applying ultrasonic energy are controlled such that the strand has the above-described tenacity. A nonwoven web comprises the strands with enhanced tensile strength.

摘要： An apparatus and method for increasing the heating efficiency of a nonwoven web using heated air are provided. A flow modifier including a turbulence inducing bar arrangement is positioned between the heated air supply and the nonwoven web. The flow modifier increases the turbulence of the heated air before it contacts the nonwoven web, resulting in more thorough penetration of the web by the air, and better convective heat transfer between the heated air and the nonwoven web.

摘要： A process for the thermomechanical treatment of a fleece web which is comprised of filaments and/or fibers of a thermoplastic synthetic resin in a continuous process. The fleece web is moved during the thermal treatment continuously and with uniform speed. The fleece web passes initially a thermal treatment station and in this is traversed by a gas stream of predetermined gas flow velocity and gas flow temperature and is heated to a preheating temperature. The preheated fleece web is subjected to mechanical treatment. The gas flow temperature and the gas flow velocity on the one hand and the treatment stretch of the fleece web in the thermal treatment station on the other are so selected that the preheating temperature at all speeds which can be assumed by the fleece web, including zero speed, does not exceed the temperature of the melting point of the filaments and/or the fibers. Also apparatus for carrying out the process of the invention are given.

摘要： Multicomponent thermoplastic continuous filaments are provided, including hollow core multicomponent filaments. The filaments are at least partially splittable into smaller filaments in the absence of mechanical treatment or application of high pressure water jets. The surface energy of the components can be controlled to control separation of the multi-component filaments. Sub-denier and micro-denier filaments of low orientation can be produced from relatively high molecular weight polymers to produce nonwovens of surprising strength, barrier, and cover.
