Problems solved by technology
Each type of antibacterial agent has its own advantages and disadvantages. Organic antibacterial agents have good effects and many varieties. They are currently the most widely used antibacterial agents. However, they have problems such as poor high temperature resistance and stability, and are difficult to use in synthetic fiber spinning processes; natural Antibacterial agents usually have good safety, but their application range is narrow, and most of them seriously affect the shade of fabrics; inorganic antibacterial agents have good heat resistance, but it is difficult to obtain durable effects when used in textile finishing, and most varieties contain heavy metals. toxicity problem

Embodiment 1
[0026] The preparation method of antibacterial finishing agent comprises the following steps;
[0027] Step 1 Add 186 parts of vinyl-terminated polyurethane emulsion, 10 parts of surface-modified nano-titanium dioxide, 8 parts of sodium lauryl sulfate, and 4 parts of OP-10 into the reactor, stir, and raise the temperature to 86 °C;
[0028] Step 2 Add the aqueous initiator solution, 20 parts of butyl acrylate, 7 parts of acrylic acid, 6 parts of methacryloxypropyl triethoxysilane, 0.8 parts of initiator ammonium persulfate to the reaction kettle dropwise within 2 hours. Dissolve 20 parts of deionized water, after the dropwise addition, keep the reaction at 85°C for 1 hour;
[0029] Step 3: Lower the temperature of the reaction kettle to below 50°C and pass through a 200-mesh sieve to obtain an antibacterial finishing agent for textiles.
[0030] Described surface modification nano titanium dioxide is made by following method:
[0031] Put 15 parts of titanium dioxide with an...

Abstract
The invention relates to a preparation method of an antibacterial polyester fabric. The preparation method of the antibacterial polyester fabric comprises the following steps: A, preparation of a finishing liquid from a 15-30 g/L antibacterial finishing agent and a 4-6 g/L silicone oil softener; B, padding of the antibacterial finishing liquid: double-dip-double-nip is performed, and the padding ratio is 90%-100%; C, drying at 170 DEG C for 30-50 s; D, high-temperature tentering at 210 DEG C for 20-30 s. Defects of poor stability of nanoscale antibacterial agents are overcome, and safety, durability and high efficiency of the antibacterial polyester fabric are achieved.
Description
technical field [0001] The invention relates to a preparation method of polyester antibacterial fabric, which belongs to the field of functional textiles Background technique [0002] Microorganisms have seriously affected human life, and pathogenic microorganisms have caused great harm to the human body. Fabric antibacterial finishing is exactly one of the methods for people to eliminate these pathogenic microorganisms. [0003] Antibacterial agents for textiles can be divided into three categories: natural, organic and inorganic. Each type of antibacterial agent has its own advantages and disadvantages. Organic antibacterial agents have good effects and many varieties. They are currently the most widely used antibacterial agents. However, they have problems such as poor high temperature resistance and stability, and are difficult to use in synthetic fiber spinning processes; natural Antibacterial agents generally have good safety, but their application range is narrow, a...
