▎ 摘  要

NOVELTY - A flexible wave-absorbing fabric comprises a resistive periodic pattern layer, a fabric medium layer, a reflective layer or a conductive layer from top to bottom. USE - Flexible wave-absorbing fabric used in wearable device, electromagnetic shielding (all claimed), mobile phone, medical instrument, clothes and curtain. ADVANTAGE - The fabric has wide frequency absorption, flexibility, adjustable frequency band and excellent design, and is prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of flexible wave-absorbing fabric, which involves (s1) designing the shape, size and arrangement of periodic pattern units, and confirming the fabric medium layer, (s2) adhering the conductive film on the transfer film, cutting the periodic pattern on the conductive film, and removing the portions other than the periodic pattern, (s3) hot-pressing TPU (thermoplastic polyurethane) film on the surface of the fabric medium layer, hot-pressing the periodic pattern, and tearing the transfer film, and (s4) providing the reflective layer or conductive layer on the other side of the fabric medium.
