Problems solved by technology

This method is complicated in process and high in energy consumption, and the nano-silver product obtained has a large particle size and is easy to agglomerate. The particle size of the carrier is generally about 1 micron after ultrafine grinding
Adding this powder will easily block the spinneret holes during the production process, resulting in high spinning end-break rate, poor post-processing tensile properties, and low product strength.
And reducing the addition of powder affects the antibacterial effect of the fiber, which cannot meet the use requirements in the production of finished products

Embodiment 1

[0028] Manufacturing process:

[0029] Weigh AgNO 3 200-2000 grams, dissolved in 100 liters of water, add 150-600 grams of concentrated NaOH and keep stirring. Then add 3-20 kg NH 4 OH mixed well. 1-2 kg of glucose is added under stirring to prepare a nano silver aqueous solution. 1-2 kg of polyvinylpyrrolidone (PVP) is dissolved in the aqueous nano-silver solution, and mixed evenly to prepare the nano-silver hydrosol.

[0030] Adding 10-30 liters of n-butanol solution with a total weight of 10-30 liters into the nano-silver hydrosol, heating the mixture in a water bath to 80° C.-85° C., stirring for 1-2 hours, and then cooling down to room temperature. After the natural separation of the oil-water mixture, the silver nanoparticles will spontaneously transfer from the water phase to the n-butanol phase.

[0031] The organic and aqueous solutions were left to cool to room temperature, and the water and n-butanol solution were separated by liquid phase method. The separate...

Abstract

The invention discloses antibiotic fiber and a preparation method of fiber product. According to the invention, an aqueous nano-grade silver antibiotic agent is prepared into organic nano-grade silver sol by using a chemical phase transferring method, such that the antibiotic agent has a good compatibility with a high polymer substrate; the sol is directly mixed with high polymer, and the mixture is dried, such that an antibiotic high polymer is prepared. The obtained antibiotic high polymer has characteristics of good versatility, good dispensability, simple technology, good processability, good temperature tolerance, and no environmental pollution. With methods of spinning or melt blowing, the antibiotic high polymer can be directly used for preparing antibiotic fibers and antibiotic fiber products. The obtained antibiotic fibers and antibiotic fiber products have excellent performances of rapid and long-lasting antibiotic effect. The physical properties of the antibiotic fibers and the antibiotic fiber products are not changed with additional antibiotic agents.

Description

technical field [0001] The invention relates to an antibacterial high polymer obtained by combining nanotechnology and high polymer. The aqueous nano-silver antibacterial agent is prepared into an organic phase nano-silver sol by chemical phase transfer method, so that the antibacterial agent has good compatibility with the polymer matrix. And after directly mixing and drying the sol with the high polymer, various antibacterial fibers can be prepared, and the fiber products prepared from the fibers have long-lasting antibacterial effect. Background technique [0002] At present, synthetic fiber products occupy a very important position in people's daily life and industrial and agricultural production. In order to make synthetic fiber products more widely used, people often add antibacterial agents in the preparation of fibers to obtain antibacterial fibers. The antibacterial agents used in antibacterial fibers can be classified into inorganic, organic and natural. Organic...
