摘要： A blown film process for producing low gauge, latent elastic films with high cross-direction orientation includes preferentially regulating the temperature gradient of the film along the expansion length. The regulation of temperature along the bubble profile allows more effective “down gauging” of the film and improved melt strength of the hot film. The choice of raw materials is an important element in producing cross-direction-oriented, low gauge, latent elastic films. The method of this invention can be carried out as either a multiple-bubble process or a single-bubble process.

摘要： A targeted elastic laminate material is provided having at least one low tension zone with first filaments having a first basis weight and at least one high tension zone having second filaments with a second basis weight greater than the first basis weight. The second basis weight is greater due to increased average thickness of the second filaments and/or increased frequency of second filaments relative to the first filaments. Methods and modifications of those methods are provided to produce a targeted elastic laminate material according to the preferred embodiments of this invention.

摘要： A nonwoven web and method of preparing a novel nonwoven web of synthetic fiber are disclosed. An aqueous solution amide crosslinked synthetic precursor polymer is extruded under defined conditions through a plurality of die orifices to form a plurality of threadlines. The threadlines are attenuated with a defined primary gaseous source to form fiber under conditions of controlled macro scale turbulence and under conditions sufficient to permit the viscosity of each threadline, as it leaves a die orifice and for a distance of no more than about 8 cm, to increase incrementally with increasing distance from the die, while substantially maintaining uniformity of viscosity in the radial direction, at a rate sufficient to provide fiber having the desired attenuation and mean fiber diameter without significant fiber breakage. The attenuated threadlines are dried with a defined secondary gaseous source. The resulting fibers are deposited randomly on a moving foraminous surface to form a substantially uniform web. The moving foraminous surface is positioned about 10 to about 100 cm from the last gaseous source to contact the threadlines. The fibers have a mean fiber diameter in the range of about 0.1 to 30 Am and are substantially free of shot. The attenuating and drying steps are carried out under conditions of controlled macro scale turbulence.

摘要： A porous, nonwoven liquid-activated barrier which includes a fibrous nonwoven web in which at least about 50 percent by weight of the fibers constituting the fibrous nonwoven web are prepared from a liquid-swellable polymer which is not significantly soluble in the liquid. In addition, the fibers of the fibrous nonwoven web have diameters in a range of from about 0.1 to about 100 micrometers. The pores of the fibrous nonwoven web have a longest dimension in a range of from about 0.3 to about 300 micrometers. In the presence of liquid, the fibers swell to an extent sufficient to substantially block the passage of liquid through the fibrous nonwoven web. In many instances, the liquid will be water.

摘要： Improvements to processes and equipment for the manufacture of nonwoven webs useful in numerous applications including personal care, protective apparel, and industrial products. The fiber and/or filaments used to form the nonwoven fabric are deposited on a forming surface in a controlled orientation using application of an electrostatic charge to the fibers and/or filaments in combination with directing them to an electrode deflector plate while under the influence of the charge. The plate may be made up of teeth with a separation and angle orientation that are selected in accordance with the desired arrangement of the fibers and/or filaments in the nonwoven web. As a result, properties of the web such as relative strengths in the machine direction and cross-machine direction can be controlled.
