Title:
FIBER CLOTH HAVING FUNCTIONAL COMPOSITE PARTICLES AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/015621
Kind Code:
A1
Abstract:
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 same into a vacuum physical vapor deposition (PVD) process furnace for condensation; depositing a PVD ceramic layer 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 fiber cloth, fiber cloth with a long lasting antibacterial effect can be obtained.
