Abstract
The invention discloses a copper-modified antibacterial polyester fiber and a preparation method thereof. The polyester fiber contains 1-30wt% of copper particles. The preparation method comprises the following steps: (1) mixing metal copper powder in benzotriazole solution to steep for 20-90min after smashing the metal copper powder, and then drying the steeped copper particles to obtain modified copper particles with anti-oxidation modified surface; (2) adding the modified copper particles into high-viscosity polyester chips, and melting to pellet to obtain copper-modified polyester master batch; (3) mixing the copper-modified polyester master batch with the polyester chips, adding a dispersing agent and a lubricating agent to uniformly mix, and drying in a vacuum state to obtain a blend spinning raw material; and (4) carrying out melt spinning on the blend spinning raw material with the melting temperature of 270-295 DEG C to prepare the copper-modified antibacterial polyester fiber. Compared with the prior art, the preparation method is relatively easy to popularize and apply, relatively low in production cost and simple in production process.
Description
technical field [0001] The invention relates to the technical field of preparation of functional polyester fibers, in particular to a preparation technology of copper-modified antibacterial polyester fibers. Background technique [0002] In people's daily life, all kinds of textiles are a good living place for microorganisms and an important source of disease transmission. With the rapid development of industry and the continuous improvement of people's living standards, antibacterial problems have attracted more and more attention. Antibacterial fibers greatly increase the added value of textiles. While developing high-tech textiles, developing textiles with antibacterial functions is also one of the important development directions. [0003] The development of existing antibacterial polyester fibers is mostly made by adding nanometer metal oxide antibacterial agents and blending and spinning. For example, the patent document whose patent application number is 20091015244...
