▎ 摘　　要

NOVELTY - Preparing yarn protective-type flexible photocatalytic fabric comprises (i) covering the surface of the textile yarn with a conductive material to obtain a conductive yarn; (ii) attaching a photocatalytic material on the surface of the conductive yarn to obtain a photocatalytic yarn; and (iii) making the photocatalytic yarn into a fabric. USE - The method is useful for preparing yarn protective-type flexible photocatalytic fabric. ADVANTAGE - The method reduces the loss of the photocatalyst during use, reduces the damage of the external environment to the carrier, and increases the service life of the photocatalytic fabric, provides material for increasingly serious environmental pollution control, can broaden the application fields of textile fibers, which has positive practical significance for the sustainable development of the textile industry, product transformation and structural adjustment.
