Problems solved by technology

[0002] Microorganisms usually do not cause harm to the human body, but once the flora is out of balance, they will multiply and cause harm to human health through the human skin, respiratory tract, digestive tract and reproductive tract mucous membranes
As a necessity for human beings, textiles are an important medium for spreading pathogenic bacteria. Currently, antibacterial agents used in textiles are divided into three categories: organic, inorganic and natural. Natural antibacterial agents are generally safer, but have poor stability; organic antibacterial agents have initial It has the advantages of strong bactericidal power and fast sterilizing speed, but it has the disadvantages of poor heat resistance, certain toxicity, easy oozing, not resistant to washing, and short service life; the inorganic antibacterial agent is mainly silver-based antibacterial agent, which has a relatively high antibacterial effect. Good, good washability, good heat resistance and stability, but it is easy to block the spinneret in the process of fiber preparation, which brings difficulties to long-term continuous spinning, resulting in high unit consumption and decreased yield, and the antibacterial properties of the fiber The shortcomings of low efficiency and narrow application range of performance

Embodiment 1

[0019] The preparation method of the fiber with antibacterial, deodorant and far-infrared functions comprises the following steps:

[0020] A. Preparation of antibacterial masterbatch

[0021] Calculated in parts by weight, the silicate mineral-loaded metal ion antibacterial agent includes 60 parts of silicate minerals and 40 parts of metal salts containing metal ions, and the silicate minerals are a combination of montmorillonite and sepiolite, wherein m (montmorillonite Soil removal): m (sepiolite) = 8:9, add silicate minerals into the mixer, first stir at 700rpm for 9 minutes, then adjust the rotation speed to 1000rpm and continue to stir for 5 minutes, mix well; then add nitric acid Add aluminum, ferric nitrate, and calcium nitrate into the stirrer for mixing and dissolving. Stir for 6 minutes at a speed of 3000 rpm and a temperature of 82°C. Finally, adjust the speed to 500 rpm and add deionized water. The amount of deionized water added is the metal salt. 100% of the vo...

Abstract

The invention relates to the technical field of spinning and weaving, and in particular relates to a preparation method of fibers with antibacterial, odor-resisting and far infrared functions. The method comprises the following steps: preparing an antibacterial agent and mixing the antibacterial agent with a chemical fiber matrix slice; melting and extruding to prepare antibacterial master batches; melting the antibacterial master batches and chemical fibers and spinning to produce the fibers with the antibacterial, odor-resisting and far infrared functions. The antibacterial fibers provided by the invention have the advantages of stable process and very good spinnability, and have the odor-resisting and far infrared functions; an antibacterial rate on escherichia coli, staphylococcus aureus and candida albicans is greater than or equal to 99 percent; the fibers have an excellent water washing resisting property, and the antibacterial rate is still greater than 99 percent after being washed for 50 times; the fibers have no irritation on skin; a preparation process is pollution-free, and technologies are not increased; the cost is reduced, and the economic benefits are good.
