The present application relates to fiber cloth having functional composite particles and a preparation method therefor. The preparation method comprises: placing a solid metal block consisting of functional metal particles into a crucible using an evaporation and condensation process, and heating and evaporating the same into a vacuum physical vapor deposition (PVD) process furnace for condensation; depositing PVD ceramic layers on the outer surfaces of the functional metal particles under the condensed state using a PVD process to form the functional composite particles; and screening the functional composite particles by means of a particle filter and accelerating the particles to bombard the fiber cloth, thereby implanting the functional composite particles into the fiber cloth to form the fiber cloth having the functional composite particles. The functional composite particles in the present application can reduce contact between the internal functional metal particles and external oxygen, slowly release ionic metal ions of the functional metal particles, and prolong the action time of the functional metal particles. According to the present application, by implanting the functional composite particles into the fiber cloth, the fiber cloth with a long lasting antibacterial effect can be obtained.

A soft magnetic powder according to the present disclosure comprises a particle which comprises a plurality of nanosized crystallites and an amorphous phase existing around the crystallites, wherein the crystallites have an average grain diameter of 30 nm or less, and the amorphous phase has an average thickness of 30 nm or less; and wherein when a minor axis of a cross section of the particle is determined as r, an average Fe concentration in the amorphous phase is lower than an average Fe concentration in the crystallites in a region where a depth from a surface of the particle is 0.2 r or more and 0.4 r or less.

The present invention relates to functional composite particles and the preparation method thereof. One embodiment of the present invention provides a functional composite particle including an inner core and a shell layer, wherein the inner core is consisted of functional metallic particles and has an outer surface, while the shell layer is a physical vapor deposition (PVD) ceramic layer consisted of biocompatible ceramic materials, and is attached to the outer surface of the inner core. The shell layer is a crystalline structure thereby allowing the ionic functional metallic particles to be sustained-released to the outside of the shell layer from the inner core via crystal boundaries. In the embodiment of the present invention, biocompatible ceramic materials are used to cover the outside surface of the functional metallic particles which have specific functions via the PVD process so as to form functional composite particles. The ionic functional metallic particles of the functional composite particles are sustained-released via crystal boundaries of the shell layer, leading to longer action time of the functional metallic particles.
