Embodiment 1

[0027] A modification treatment method for enhancing the antibacterial properties of polyester fibers, comprising the steps of:

[0028] (1) Polyester fiber pretreatment:

[0029] First immerse the polyester fiber in the sodium hydroxide solution, then heat to keep the temperature of the sodium hydroxide solution at 48°C, keep stirring for 2 hours, then take out the polyester fiber, and finally rinse it with deionized water and dry it for later use;

[0030] (2) Preparation of composite soaking solution:

[0031] a. Take the following materials in corresponding parts by weight: 1 part of silver nitrate, 5 parts of zinc nitrate, 90 parts of deionized water, and then put them into the stirring tank together, and after magnetic stirring for 30 minutes, add the other ingredients in the stirring tank Phytic acid with a total mass of 6% was treated with magnetic stirring for 20 minutes, then ammonia water was added to the stirring tank to adjust the overall pH value to 7.5, and the...

Embodiment 2

[0046] A modification treatment method for enhancing the antibacterial properties of polyester fibers, comprising the steps of:

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a modification treatment method for enhancing the antibacterial properties of polyester fibers. Background technique [0002] With the rapid development of the global economy and the continuous improvement of living standards, people's pursuit of quality of life tends to be healthier and more environmentally friendly. Among them, the hygienic function of textiles has attracted people's attention. There are many types of microorganisms in nature and they are everywhere. Bacteria, fungi and viruses that are harmful to the human body will multiply rapidly in a suitable environment, and spread diseases through contact, affecting human health. Textiles in daily life are good places for these microorganisms to live and are also an important medium for transmitting diseases. Therefore, The research and development of antibacterial fibers is particularly important. Polyeste...
