Embodiment Construction

[0016] A bacteriostatic acid dye, made of the following ingredients in parts by weight: 25 parts of resorcinol, 25 parts of bromic acid, 20 parts of sodium polynaphthaldehyde sulfonate, 8 parts of sodium silicate, triphenylphosphine 5 parts of sodium m-sulfonate, 6 parts of pyrazole copper, 5 parts of chitosan, 0.5 parts of nano-copper particles, 0.5 parts of nano-cuprous oxide particles, 160 parts of deionized water, 2 parts of defoaming agent, and 1 part of auxiliary agent.

[0017] Further, the auxiliary agent is made of the following ingredients in percentage: 16% sodium sulfite, 15% formaldehyde, 46% acrylic acid amide, 23% terephthalic diboronic acid; the preparation method of the auxiliary agent is: acrylic acid amide and p- Mix benzenediboronic acid, control the temperature at 65°C, and last for 40 minutes; at the same time, add formaldehyde and sodium sulfite dropwise, control the dripping in 30 minutes, heat to 80°C, cool to room temperature, and adjust the pH value t...

Abstract

The invention discloses bacteriostatic acid dye. The bacteriostatic acid dye is prepared from resorcinol, bromamine acid, sodium poly[(naphthaleneformaldehyde)sulfonate], sodium silicate, triphenylphosphine-3,3',3''-trisulfonic acid trisodium salt, pyrazolone, chitosan, nano-copper particles, nano-cuprous oxide particles, deionized water, a defoaming agent and an auxiliary. According to the bacteriostatic acid dye, the stability is high, and use is convenient; by optimizing the dye components and cooperatively using the home-made auxiliary, the coloring power of the dye is enhanced, the problem that the color fixing effect of traditional acid dye on a chinlon fabric dyed by the acid dye is not ideal is solved, and the effect of the wet treatment fastness is greatly improved; in the preparing process of the acid dye, the components are divided into two parts to be processed through mixing separately and then processed through total mixing, and by cooperating with the added auxiliary, the dye components can be greatly homogenized, and the coloring effect and the coloring quality of the dye are improved; the dye has the very good antibacterial property on escherichia coli, staphylococcus aureus and candida albicans.

Description

technical field [0001] The invention relates to the field of dyes, in particular to a bacteriostatic acid dye. Background technique [0002] Acid dyes are a kind of water-soluble dyes with acidic groups in their structure, and they are dyed in acidic medium. It is mainly used for dyeing wool, silk and nylon, and can also be used for leather, paper, ink, etc. It generally has no coloring power to cellulose fibers, and the acid dyes have a complete spectrum and bright colors. The light fastness and wet treatment fastness vary with the dye. Varieties vary widely. Compared with direct dyes, acid dyes have a simple structure, lack of longer conjugated double bonds and homoplanar structures, so they lack directness to cellulose fibers and cannot be used for dyeing cellulose fibers. Different types of acid dyes have different dyeing properties due to their different molecular structures, and the dyeing methods used are also different. Contents of the invention [0003] The pur...
