Abstract

The invention provides anti-ultraviolet powder, a preparation method of a master batch and a production method of anti-ultraviolet functional fibers. The anti-ultraviolet powder comprises the following components in percentage by mass: 18.4-37.2% of CePO4 nano-powder of a core-shell structure, 55.8-74.4% of TiO2 nano-powder and 7-8% of a dispersing agent. The anti-ultraviolet master batch is prepared by stirring and granulating the anti-ultraviolet powder, an antioxidant, a coupling agent and a polyester matrix. The anti-ultraviolet master batch comprises the following components in percentageby mass: 15-30% of the anti-ultraviolet powder, 0.1-0.3% of the antioxidant, 0.3-0.7% of the coupling agent and 69-84.6% of polyester powder, and anti-ultraviolet polyester fibers are prepared by a spinning process. The invention has the innovation points that the novel inorganic CePO4 serves as the material of the anti-ultraviolet powder, and the functional polyester fibers can be prepared.

Description

technical field [0001] The invention belongs to the field of anti-ultraviolet of plastics, relates to PET fibers, in particular to a preparation method of an anti-ultraviolet powder, a master batch and an anti-ultraviolet PET functional fiber. Background technique [0002] In recent years, the output of PET fiber has shown a continuous growth trend. With the increase of industrial investment, technological breakthroughs and scale accumulation, the PET fiber industry will usher in greater development in the foreseeable future. However, people's requirements for the quality of textiles are gradually increasing, and their environmental protection and functionality have become two aspects that people are increasingly paying attention to. Traditional textiles can no longer meet the needs of the modern market. The research and development of functional fibers has become the main development direction of modern fibers. In recent years, with the improvement of people's health awaren...
