20080216205 | Breathable waterproof garment - A garment containing a breathable laminate that is optionally bonded to an outer layer fabric and an optional inner layer fabric. The breathable laminate is constructed from a microporous membrane situated in a face to face relationship with a nanoweb and optionally bonded thereto. | 09-11-2008 |
20080220676 | Liquid water resistant and water vapor permeable garments - A water resistant garment is disclosed having regions of high MVTR while maintaining water resistance. The garment has a fabric layer adjacent one major surface of a nanofiber layer. The surface of the nanofibers are coated with a coating containing a fluorocarbon polymeric moiety and a resin binder or extender which is soluble in water and/or other solvents. The coated nanofiber layer has a contact angle of greater than 145°. The garment optionally includes a second fabric layer adjacent the other major surface of the nanofiber layer. The garment has regions having a Frazier air permeability of between about 0.5 m | 09-11-2008 |
20090029885 | META- AND PARA-ARAMID PULP AND PROCESSES OF MAKING SAME - The present invention relates to meta- and para-aramid pulp for use as reinforcement material in products such as seals and friction materials. The pulp comprises (a) fibril free meta-aramid particles, (b) irregularly shaped, para-aramid fibrous structures, and (c) water, whereby the para-aramid fibrous structures contact and are wrapped partially around at least some of the meta-aramid particles. The invention further relates to processes for making such aramid pulp. | 01-29-2009 |
