Publication number: 20090291249Abstract: An impact resistant membrane and methods of preparing and utilizing the membrane are disclosed. The membrane comprises a loft layer, a first polymeric layer bonded to a first surface of the loft layer, and a second polymeric layer bonded to a second surface of the loft layer. The membrane can be fabricated by providing a loft layer and applying a polymeric layer on a first surface and on a second surface of the loft layer. The membrane has a higher resistance to failure due to impact and thus protects the underlying structure membrane for a longer time. A method of facilitating protecting a structure comprises providing a single ply membrane having a loft layer and a polymeric layer disposed on at least two surfaces of the loft layer.Type: ApplicationFiled: May 23, 2008Publication date: November 26, 2009Inventors: Naresh R.

Publication number: 20050210598Abstract: A method for producing an improved washed and plushed upholstery fabric in a continuous process includes the provision of a soft, dimensionally stable, nonwoven fabric backing. After the chemical application of an anti-migrant and softener, the fabric is washed in a rope form, opened and de-twisted. After the fabric is rewound and further coatings are applied, an adhesive is applied to hold a nonwoven web to the previously prepared fabric in a rewinding process. The fabric is then subjected to a steam flow process to enhance the fabric texture and reduce the width of the fabric.Type: ApplicationFiled: March 14, 2005Publication date: September 29, 2005Inventors: Duncan Whitehead, Justin Silvia, David Pettey, Xu Cai
