摘要： In the invention, a method is provided for producing a composite nonwoven fabric. A polymer is extruded into heated continuous filaments, possibly elastic, from the die head to a first chilled roller, wherein the extruder is configured to provide the continuous filaments to the chilled roller in a canted direction that is at a tangent or angle to the surface of the first chilled roller. The filaments are conveyed in a downward direction by way of chilled rollers to a nip. In a next step, the nonwoven web is sprayed with an adhesive and is laminated on the continuous filaments in the nip to form a composite nonwoven fabric. The continuous filaments move vertically downward approximately in line with the lamination process, facilitating automatic re-threading of filaments when they are broken or interrupted in their travel downward onto the chilled rolls.

摘要： A composite that contains an elastic film laminated to a meltblown facing is provided. During lamination, apertures and discrete bond sites may be concurrently formed in the elastic film. The discrete bond sites may be located proximate (adjacent or near to) a perimeter defined by corresponding apertures formed by displacement of the film. The location of the bond sites adjacent to or near the apertures may enhance the durability of the meltblown facing by strengthening the area surrounding the apertures. Furthermore, the content of the elastic film and the temperature/pressure of lamination may be selected to that the film possesses a sufficient tack for adhering to the facing at regions other than those fused together by the bonding elements of the patterned roll. Such secondary bonding further stabilizes the meltblown facing and renders it suitable for printing. Further, the film is under tension in the machine direction during lamination. Subsequent to lamination, however, the film is retracted so that the facing retracts toward its original machine direction length, thereby gathering and forming pleats. It has been discovered that these pleats have a relatively small amplitude (height), as well as a substantially uniform frequency across the surface of the facing. Such a small height and increased regularity improves the ability to transfer an ink to “peaks” of the pleats, thereby improving print quality and uniformity.
摘要翻译： 提供了一种包含层压在熔喷面上的弹性薄膜的复合体。 在层压期间，可以在弹性膜中同时形成孔和离散的接合位点。 离散的接合位点可以位于由通过膜的位移形成的相应孔限定的周边（邻近或接近）附近。 靠近孔附近的接合位置的位置可以通过加强孔周围的区域来增强熔喷面的耐久性。 此外，可以选择弹性膜的含量和层压温度/压力，使得该膜具有足够的粘合性，以便通过图案化辊的粘结元件熔融在一起的区域以外的区域附着在面上。 这种二次粘合进一步稳定了熔喷面，使其适合印刷。 此外，膜在层压期间在机器方向上处于张力下。 然后，在层压之后，膜缩回，使得面朝向其原始机器方向长度缩回，从而收集和形成褶。 已经发现，这些褶皱具有相对较小的幅度（高度）以及穿过表面的表面的基本均匀的频率。 这样小的高度和增加的规则性提高了将油墨转移到褶皱的峰值的能力，从而提高了印刷质量和均匀性。

摘要： A latent elastic laminate material, and methods of making latent elastic laminate materials. The laminate includes a latent polymer, which itself may or may not possess latent elasticity, that is applied to at least one elastic member while the elastic member is in a stretched configuration. The elastic member, at least partially covered with the latent polymer, is attached to at least one substrate. The amount of latent polymer applied to the elastic member may provide enough force to overcome a retractive force of the elastic member when the latent polymer is at a temperature below a softening point of the latent polymer, yet the amount of latent polymer may be small enough to allow the laminate to retract into an elastic, gathered structure when the laminate is heated to a softening point of the latent polymer. The laminate may be incorporated into a variety of articles including personal care garments and cleaning cloths.

摘要： The present invention comprises a continuous feed spun bonded laminate having improved elastic properties measured at body temperature. The laminate comprises at least one first and second nonelastic layers between which is sandwiched at least one elastic layer, the elastic layer being comprised of a triblock polystyrene-poly(ethylene/propylene)-polystyrene (“SEPS”) copolymer having a number average molecular weight of about 81,000 g/mol. The weight percent of styrene is approximately 18% and the weight percent of ethylene/propylene is approximately 82%. The molecular weight increase in the EP block, while holding the molecular weight of the styrene block constant, increases the entanglement density, polymer chain persistence length and the relaxation time. The resulting laminate load decay rate and load loss measurements over a period of 12 hours at body temperature showed marked improvement over known CFSBL product. The laminate is particularly useful as side panel material in training pants because of the resistance to sagging at body temperature.
