POLYESTER NONWOVEN FABRIC, NONWOVEN FABRIC PRODUCT THEREOF AND VARIOUS PRODUCTS USING THE NONWOVEN FABRICS REINFORCING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2002/070805
Kind Code:
A1
Abstract:
A nonwoven fabric mainly comprising polyester short fibers and polyester binder short fibers, and is provided with such physical properties that a shrinkage percentage at a 150 °C x 15-min heat treating is up to 2% in both longitudinal and lateral directions and a tensile strength is at least 15 N/5cm in both longitudinal and lateral directions. Such a high-strength, low-shrinking polyester nonwoven fabric used does not adversely affect human bodies by scattering broken fibers at handling unlike glass fiber cloth, nor pose an environmental problem that might be caused by debris left after burning carpets. Especially, when this nonwoven fabric is embedded in the backing layers of various carpets, it bonds strongly to a resin component constituting the backing layer to deliver a reinforcing effect stronger than glass fiber cloth.
