Publication number: 20180333933Abstract: 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.Type: ApplicationFiled: July 23, 2018Publication date: November 22, 2018Inventors: Karl F. Humiston, Gerald P. Rumierz, JR., Dickie J. Brewer

Publication number: 20170266865Abstract: At least a selected microporous membrane is made by a dry-stretch process and has substantially round shaped pores and a ratio of machine direction tensile strength to transverse direction tensile strength in the range of 0.5 to 6.0. The method of making the foregoing microporous membrane may include the steps of: extruding a polymer into a nonporous precursor, and biaxially stretching the nonporous precursor, the biaxial stretching including a machine direction stretching and a transverse direction stretching, the transverse direction including a simultaneous controlled machine direction relax.Type: ApplicationFiled: May 1, 2017Publication date: September 21, 2017Inventors: Xiaomin Zhang, Gerald P.
