Problems solved by technology

This method uses a lot of organic solvents, which is not conducive to environmental protection, and the preparation method is relatively complicated
[0004] In addition, the raw copper (copper source) selected for the existing copper masterbatches on the market is copper oxide or metal copper powder, and the original processing methods cannot avoid further oxidation of the copper source during the granulation process, making the masterbatch For back-end (spinning) application, the fiber itself has color, such as green, yellow, copper, or gray
Due to the darker color of the fiber itself, the color problem cannot be solved through further processing into textiles, so that the final product cannot be white or light-colored

Abstract

The invention provides a copper master batch and a preparing method thereof. The copper master batch is prepared from, by mass, 75%-96% of PET and 4%-25% of modified nano-copper. The preparing method includes the following steps that the modified nano-copper and the PET are mixed, and a mixed solution is formed; the nano-copper is evenly distributed in a PET base material; the mixed solution obtained in the step S1 is subjected to vacuum reaction prilling, and the copper master batch is obtained. According to the copper master batch and the preparing method thereof, copper with the nanometer particle size and the PET base material are fully and evenly subjected to mixing granulation, the problems that reaction prilling is high in pollution and energy consumption, low in purity and unstable in PH value are solved, the nanometer activity of the copper is fully reserved, and the copper master batch and the preparing method thereof are environmentally friendly, free of pollution and low in energy consumption.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and in particular relates to a copper masterbatch and a preparation method thereof. Background technique [0002] In today's society, the extreme environment, environmental pollution and other ecological environments have seriously deteriorated, and special living microenvironments such as confined spaces have led to an urgent need for functional protective textiles. At present, the fibers used to prepare textiles do not have antibacterial ability, and under certain conditions, they will provide an environment for bacteria to survive and reproduce, threatening human health. The main method to solve the antibacterial problem of fibers is to use antibacterial nanoparticles and polymer groups for composite modification to prepare modified fibers with antibacterial effects. The fiber will gradually release antibacterial ingredients during use to achieve the purpose of antibacterial. At prese...
