The modacrylic component also serves to add strength to the char-forming fiber by softening and thereby binding to the charring fibers. The fibers are blended together and homogenized into a lightweight fiber web which is stacked in staggered layers to form a low density batting.Type: ApplicationFiled: November 27, 2006Publication date: May 29, 2008Inventor: Paul H.
