A glass-fiber-containing nonwoven polymer web is prepared by providing a nonwoven polymer web, applying a layer of glass fibers onto the nonwoven polymer web, and encapsulating the glass fibers into the nonwoven polymer web utilizing heat and pressure. Alternatively, a glass-fiber-containing polymer web is prepared by providing a first nonwoven polymer web, applying a layer of glass fibers onto the first nonwoven polymer web, superposing over the layer of glass fibers a second nonwoven polymer web, and laminating together the assemblage to encapsulate the glass fibers. |
