Abstract: A multi-fiber blended thermal-insulating wadding, a preparation method therefor and an application thereof. The multi-fiber blended thermal-insulating wadding is prepared by mixing, by weight, 60-90% of viscose fiber, 0-30% of fine denier polyester fiber, and 10-40% of three-dimensional crimped polyester fiber; fiber materials are opened and mixed twice by an opener, and then are fed into a carding machine to be carded; a fiber net is treated by a random roller, so that the fibers are rearranged to be criss-cross in 12 directions, and then are introduced into a pre-needling machine to be pre-needled and into a lower needling machine for bottom surface needling. The multi-fiber blended thermal-insulating wadding has excellent wearability, can well meet the basic performance requirements of the thermal-insulating wadding, and has relatively high physiological comfort. In addition, the multi-fiber blended wadding enhances the bulkiness, air permeability and heat retention on the basis of a relatively low thickness by increasing the content of the three-dimensional crimped polyester fiber and the fine denier polyester fiber, thereby further reducing production costs.
