    摘要： The present invention is directed to novel, improved, modified or treated microporous membranes for use in textile related applications and which are preferably composed of two or more dissimilar porous membrane or material layers laminated together using heat, compression and/or adhesives. The preferred inventive laminated composite microporous membrane is modified using a technique or treatment such as microcreping to introduce permanent small, regularly spaced, crepes, profiles, compactions, pleats, or wrinkles into the laminated composite microporous membrane for the purpose of improving mechanical strength, elasticity and/or resiliency. In addition, the inventive microcreped microporous laminated membrane more preferably has significantly improved ‘hand’ or softness, has ‘next-to-the-skin’ softness, and/or is quiet without crinkling noises during movement, which may be desired performance properties or characteristics of or in textile garments, materials or applications.

    摘要： Methods for measuring and/or mapping in-plane strain of a surface of a substrate. A grating is formed on at least a portion of the surface of the substrate. A laser is then used focused onto the grating to determine the strain on the surface by determining the variation of the grating wavelength due to the strain on the surface. The strain information is essentially carried by the grating, in terms of grating wavelength, because it varies according to the volume change of the underlying substrates. By scanning the surface grating with the small laser size, a high resolution strain map of the surface can be produced. The induced strain is related to the grating wavelength variation, which leads to the diffraction angle variation that is captured by the strain sensing measurements.

    摘要翻译： 用于测量和/或映射衬底表面的面内应变的方法。 在基板表面的至少一部分上形成光栅。 然后将激光器聚焦到光栅上，以通过确定由于表面上的应变引起的光栅波长的变化来确定表面上的应变。 根据光栅波长，应变信息基本上由光栅承载，因为它根据下面的基底的体积变化而变化。 通过以小的激光尺寸扫描表面光栅，可以产生表面的高分辨率应变图。 感应应变与光栅波长变化有关，这导致了应变感测测量所捕获的衍射角变化。

    摘要： A dunnage crumpling apparatus is provided having first and second entry-side crumpling members and first and second exit-side crumpling members. The first and second entry-side crumpling members define an entry therebetween. The first and second exit-side crumpling members define an exit therebetween that is disposed along the longitudinal path downstream of the entry. A crumpling zone being defined between the entry and exit. The first entry-side crumpling member is configured for moving at an first rate and is associated with the second entry-side crumpling member for moving sheet material through the entry in a first direction along a longitudinal path at an entry rate. The first exit-side crumpling member is configured for moving at an second rate and is associated with the second exit-side crumpling member for moving the sheet material through the exit in the first direction along the path at a exit rate that is slower than the entry rate to crumple the sheet material for producing dunnage. The entry and exit-side crumpling members are displaced laterally along the path with respect to each other to cause shearing of the sheet within the crumpling zone.
