Abstract
Nonwoven textile fabrics in accordance with the present invention include a web of entangled polymeric fibers with substantially pectin-free, individualized bast fibers having a mean length less than 9 millimeters (mm). A method of making a nonwoven fabric includes forming a web of polymeric fibers, forming a randomly arrayed fiber web of the substantially individualized bast fibers having a mean length less than 9 mm, disposing the web of the substantially individualized bast fibers onto the web of polymeric fibers, and entangling the polymeric fibers with the substantially individualized bast fibers to form the nonwoven fabric. In addition, laminates include the nonwoven fabric, a film, and an adhesive disposed between the fabric and the film to bond the nonwoven fabric to the film.
