preparation example Construction

[0025] Further, the preparation method of the nano-zinc oxide composite particles includes the following steps;

[0026] Step 1. Add n-butanol to desalted water, add polyether polyol (such as polyether F127) after dissolving, add acid to adjust the pH to 1.8-2.5, and then add tetraethyl orthosilicate (such as TEOS-28) dropwise After the dropwise addition is completed, heat to 40-50°C and keep stirring for 24 hours, then raise the temperature to 100-110°C, and let it stand for 24 hours to obtain a white precipitate, which is filtered with a 0.22 μm filter membrane, and the retained material on the filter membrane is washed, Calcined after drying to obtain mesoporous silica;

[0027] Step 2. Add the zinc acetylacetonate mixture into ethanol (100%), then add the mesoporous silica obtained in step 1, heat and stir at 70° C. for 5-8 hours, collect the remaining white powder, and then wash it with ethanol. Calcining after drying to obtain nano zinc oxide composite particles.

Abstract

The invention discloses an anti-UV and antibacterial extinction chinlon chip and a preparation method thereof, and belongs to the technical field of textile, the anti-UV and antibacterial extinction chinlon chip comprises a titanium dioxide matting agent, nano zinc oxide composite particles and caprolactam; and the nano zinc oxide composite particles comprise nano-zinc oxide particles, and the peripheries of the nano-zinc oxide particles are coated with organic silicon TEOS-28. The preparation method comprises the following steps: preparing a blending solution from a titanium dioxide delustering agent and nano-zinc oxide composite particles, mixing the blending solution with acid, amine and caprolactam, and carrying out pre-polymerization, final polymerization, filtration, granulation, extraction, drying and cooling to obtain a finished product. The preparation method is low in cost input and easy to control, the used raw materials are not easy to agglomerate and disperse, and the effects of the raw materials can be fully exerted; and the anti-UV, antibacterial and matting chinlon chip is used for preparing fibers or further used for weaving, and can endow the fibers and cloth with good anti-UV, antibacterial and matting properties.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an anti-UV and antibacterial matting nylon slice and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, the technology and product quality of the nylon chip industry have been continuously improved. Nylon chips have become an important branch of the synthetic chemical material industry, and its application fields are extremely wide. With people's urgent demand for functional chemical fiber products, major enterprises in this field are increasingly active in the research and development of such products. The existing chemical fiber products prepared by matting slices cannot meet people's daily needs. Users need not only the matting function with low brightness, but also anti-ultraviolet and antibacterial functions. New products are expected to appear. In order to improve the extinction of the slices, titaniu...
